RE: using vol0
by Alan McLachlan 14 Feb '03

Simon, Assuming you have a copy on a server drive or CD somewhere with the version of Data Ontap you're running, all you need is boot floppies (for non-flash units), and a copy of the config files (rc, hosts, exports, cifsconfig.cfg, lclgroups.cfg etc). Providing you keep a backup of the config files - many of my customers simply replicate the files in the /etc directory without all the subdirs to a folder on a couple of other servers. The config files all used to fit on a floppy. In a full blown DR scenario you can then have the root volume online and ready within a few minutes, unless disks need to be zero'd then it might take 20-30 minutes. You can than start restoring the rest of the root volume (home directories, workgroup data etc). The only time this wouldn't work is if you used "snap mirror to tape" for bare-metal restores rather than regular NDMP backups. regards, Alan. -----Original Message----- From: Clawson, Simon [mailto:simon_clawson@mentorg.com] Sent: Thursday, 13 February 2003 8:31 PM To: toasters(a)mathworks.com Subject: RE: using vol0 The only benefit as I see it to having the smallest possible vol0 is recovery time. You can back up and recover the small amount of data in a few minutes on most tape devices, meaning you are up and running fairly quickly in the event of losing the volume. However, there are methods of replicating the /etc data to another volume, then telling the filer to boot this as vol0. This would of course mean any NIS maps etc are broken until you change their paths, but the filer would be up and running quicker than if you were to have to restore the whole root volume first, and you would not be using two 72Gb disks for 40mb of data. **** ASI Solutions Disclaimer **** The material transmitted may contain confidential and/or privileged material and is intended only for the addressee.

wafl scan reallocate not improving layout?

I have a volume that shows a layout of 5 when doing a wafl scan measure layout. I have tried reallocating it but it never gets below 5.

Checking netapp for bad blocks?
by Art Hebert 13 Feb '03

13 Feb '03

Our oracle database has experienced two problems lately with file corruption on our standby database. The corruption isn't on the primary database and our Oracle DBA is asking if I can do something similar to fsck on the netapp. Any thoughts on the commands to run and what to check for would be appreciated. art -----Original Message----- From: Stephane Bentebba [mailto:stephane.bentebba@fps.fr] Sent: Thursday, February 13, 2003 5:49 AM To: Jonathan Cc: Jordan Share; 'Toasters(a)Mathworks.Com' Subject: Re: Adding a drive shelf to my existing F740 Jonathan wrote: >>2 - there is an extra trick to save a spare disk : don't keep two but >>only one spare disks : a 36G one, as Filer can reconstruct a 18G broken >>disk on a 36G.

F760 thinks it has 2 shelves with ID2
by Daniel Finn 13 Feb '03

13 Feb '03

Had another (different) Netapp crash last night. One thing I don't understand is why it decided to rewrite/recompute parity? Is that normal. There's nothing abnormal in the logs above where it starts to rebuild parity. It seems it crashed because it found two shelves with ID 2, but we haven't touched this in forever and the shelf IDs should've have changed. Would it be possible for this netapp to have been functioning all this time (+6 months) with two shelves with the same ID?

Adding a drive shelf to my existing F740
by Jordan Share 13 Feb '03

13 Feb '03

We're getting a bit tight on space, and I'd like to add a drive shelf to my F740. Right now, we have 2 full shelves of 18gig drives, with 1 for parity and 1 for hot spare. What I had planned to do was get a shelf of 36gig drives, and create a second raid group, then add it to the existing volume. As I understand it, I would then have 2 hot spares (18 and 36), and two drives for parity. Are there any "gotchas" (or blatant ignorance on my part) in this scenario? Thanks, Jordan

RE: NDMP issues with 6.2.x of DataONTAP
by Jay Newton (Email) 13 Feb '03

13 Feb '03

NetApp did confirm that NDMP went from V3 to V4 from 6.1.x to 6.2.x. I tried forcing the Filer back to NDMP V3. It raced the processors up to 100% and stayed there. I had fewer backups running as well. I can't explain that behavior other than something in how DOT talks to NDMP must have changed. Have you tried this and what were your experiences?

removing a disk from a volume?
by Peter D. Gray 13 Feb '03

13 Feb '03

Is there a way to remove a disk from a volume permanently. I want to move from 18GB drives to 36GB drives and I was hoping to do it with no downtime by removing the 18Gb drives one at a time and replacing with 36GB drives. Possible or is there a better way? Regards, pdg -- See mail headers for contact information.

RE: using vol0
by Alan McLachlan 13 Feb '03

13 Feb '03

Hi Charles, Don't understand why you're asking this. In most cases that I'm aware of vol0 is used for data. In some cluster scenarious, particularly with local or remote syncmirror, it becomes necessary to burn two disks to have a root volume that's just for the filer's config files - usually only on one half of the cluster. I can't imagine apart from that why someone would want to consume two whole drives for the 40MB or so of data in the /etc directory. In fact, many of my customers have only configured a second volume in order to support a database. User home directories and workgroup data stay on vol0. You should of course make use of qutoa'd qtrees within vol0 extensively to prevent it filling up - theoretically this could cause a panic in some circumstances although Data OnTap is much more robust than a Unix or Linux in this regard. ---------------------------------------------------------------------------- --------------------------- On a related note, one issue that crops up from time to time is that when a filer is used to replace a bunch of Windows fileservers on a large CIFS network, it can happen that well-meaning Domain Admins that don't directly look after the filer and aren't trained in Data OnTAP may accidently corrupt config files in the /etc directory. It would be nice to restrict access to just a select group of trained admins. Using a Windows domain group is not the answer, as any Domain Admin can take ownership of the resource. A solution is to turn the /etc directory into a unix security style qtree: * make a new qtree called say "etcnew" * copy the files from /etc to /etcnew * rename /etc to "etcold" * rename /etcnew to "etc" * set the security style of etc to unix This works even if you only have a CIFS licence. You should then install ssaccess on a workstation to manage the security on the /etc qtree. Then, in the usermap.cfg file in /etc put an entry for each trusted admin like so: *\root => nobody (security defensive entry) DOMAIN\fred => root DOMAIN\wilma => root As the final step, set options wafl.nt_admin_priv_map_to_root to OFF. The result is that, in the example above, only the domain users "fred" and "wilma" can make changes to the /etc directory. For all the other resources on the filer (which have NTFS security style), normal domain security rules apply. -----Original Message----- From: Charles Bartels [mailto:cbartels@openharbor.com] Sent: Wednesday, 12 February 2003 3:45 AM To: toasters(a)mathworks.com Subject: using vol0 Hi, I'm configuring an F810 and space is going to be a little tight.

Has anyone seen this behavior before? Often enough that we decided to go away from mixed mode. We have ended up selecting unix on filesystems mostly accessed by unix users and ntfs on filesystems mainly used by windows users. It seemed to create less confusion that way. I haven't tried mixed mode witj ONTAP 6.x though. >>>>>>>>.rune -- Rune Bakken Senior System Administrator Telenor Business Solutions (Nextra), ManagedServices/*/IP-Services http://ips.telenor.net/

Thanks you all the people that responded to this. It sounds like there is no real easy solution, although people did have specific suggestions (snapmirror, ndmpcopy etc). Many thanks, pdg

mixed mode .vs unix mode qtrees on a NFS & CIFS filer
by Colin Eric Johnson 12 Feb '03

12 Feb '03

Here's the trouble I'm running into and the question that it raises. I'm getting ready to turn on CIFS on our filer (F820) so that our users have one file system to deal with and not two. In my experiments I have seen some strange behavior that goes something like this: If the qtrees are unix mode then my unix host that has root privs can see and manipulate files just fine. If the qtrees are mixed mode then on some files the unix host can manipulate files and on some it cannot. It can even get to the point that a file/directory that a user creates under windows cannot be accessed by that same user from unix (if the filer is in mixed mode). So, my questions are: 1. Has anyone seen this behavior before? 2. If a user disappears from Active Directory and I have to recreate them will the new SID be a problem if the user has the same name? 3. Does anyone have any thoughts on which security mode (unix or mixed) for a filer that is serving NFS to an NIS domain and CIFS to a Windows AD Domain? Thanks Colin J.

Free Disk Shelves - Non-Profit Organizations
by Allen, Pat 12 Feb '03

12 Feb '03

I apologize for the improper use of the list and I hope I don't attract too many flames. But I hope that I can be forgiven considering the potential good to be derived from the posting. We have just retired two FC-8 disk shelves which are fully populated with 18GB disks. The shelves and disks are in great shape. As a non-profit organization we are willing to donate these to other non-profit organizations. All we ask is that you supply an account for shipping. Please only reply to this post if you are a non-profit organization and have a need for this storage. --- Pat Allen (pat(a)mbari.org) Monterey Bay Aquarium Research Institute (MBARI) 7700 Sandholdt Rd, Moss Landing, CA 95039 (voice) 831-775-1724; (fax) 831-775-1620

High disk reading after upgrade
by Rune Bakken 12 Feb '03

12 Feb '03

Hi! Two nights ago we upgraded one of our systems from an F880 Ontap 6.2.2 to Ontap 6.3.1 then upgraded the head to a FAS960. The system has 3 FC-Loops with 4 DS14 (36GB Disks) on each After this we are experiencing constant high Disk reads ranging between 20000-40000kB/s, with network traffic less than 9000KB/s out, and 7000kB/s in. Disk writes matches Net in. Disk scrub is not running Suggestions? >>>>>>>>>.rune -- Rune Bakken Senior System Administrator Telenor Business Solutions (Nextra), ManagedServices/*/IP-Services http://ips.telenor.net/

Moving files from qtree up to a volume
by Steven Boyer GD-Mail 12 Feb '03

12 Feb '03

We have 5 qtree's within a volume, our help desk did a move of one of the subfolders within a qtree in this volume. We now have 5 qtree's and one shared folder under the volume. When the folder was moved from the qtree up to the volume it inherited the volume permissions. When doing a move within a volume do you not maintain the perms? Are qtree considered partitions so when you move across partitions you inherit permissions of the parent. How does my problem compare to a move or copy on a NT or 2000 system. Example: volume share share qtree1 share qtree2 share qtree3 share qtree4 share qtree5 folder in qtree1 moved under vol\share Thanks Steven

NDMP issues with 6.2.x of DataONTAP
by Jay Newton (Email) 12 Feb '03

12 Feb '03

We are experiencing issues with NDMP backups. I'm hoping other people in this group have seen it as well and may have suggestions for us to try. Here's an explanation of what has happened. On 12-13-2002 we upgraded from 6.1.3r2 to 6.2.1r2 to fix issues with Autosupports not being sent in the event of hardware failure. A couple of things went sour after the upgrade. Our SnapManager for Exchange performance went down more than 30%, NDMP backups would run slow intermittently, and general Filer performance got worse. NetApp discovered a memory leak in 6.2.1r2 in the NDMP daemon about the same time we upgraded to 6.2.1r2. We had to upgrade to 6.2.2d8 to fix that issue. However, a backup or two will invariably run slower than the rest. If the backup is restarted, it usually picks up speed and runs normally. By slow I mean 10 gigs in 10 hours on a DLT8000 drive. I used to get 20-30 gig per hour before we upgraded to 6.2.1r2. This can happen with each of the 4 DLT8000 drives attached to the Filer meaning that I can't pin the problem to a bad piece of hardware. Today we have discovered that snapshots for backup are not deleting correctly. The NDMPD process was holding the snapshot hostage. A volume ran out of space due to this issue. We were able to kill the NDMPD sessions that were holding the snapshot open and the snapshot deleted normally. Has anyone else experienced similar issues? For those of you running SnapManager for Exchange, how big are your databases and how long does it take to verify them? Also, those who run multiple backups, what is your CPU utilization like when running 4 simultaneous backups and what is your tape throughput?

Real Time Virus Scanning with F820 and Norton AV
by Pucky, Todd M. 12 Feb '03

12 Feb '03

Has anyone had success running real time virus scanning on cifs shares on an F820 (Ontap 6.1.2.R1) or any other filer? I have a dedicated Windows 2000 server with Norton Antivirus Corporate Edition 7.xx, but I have not been able to get real time virus scanning to work correctly. How do you register the filer with the virus scanning software? Do you have to use mapped drives on the Windows 2000 virus scanning server that point to volumes on the filer? Are most of you using real time scanning on your filers or do you use scheduled or manual virus scans? Any input would be greatly appreciated.

Todd, You can not use Norton Corporate Edition for Realtime File Protection on Netapps, you must use specific AV products that talk to OnTap like Symantec Carrier Scan, Trend ServerProtect for Network Appliance, and McAfee (their product name escapes me). You can get a review at http://www.netapp.com/tech_library/3107.html. I did extensive testing when this release & went with the Trend product. I'm not dissing the other 2 products, I just believe in the results I found when I tested. Larry -----Original Message----- From: Pucky, Todd M.

Agreed. We ran Trend ServerProtect for Netapps for a while with a demo license and we were very happy with it. The only thing that kept us from buying it was the sudden disappearance of all of our budget. (This was some time ago under a previous parent company; we're just about getting this all sorted out now.) As for how to get the virus protection working, if it is similar to how it worked for ServerProtect, you have to install the Netapp anti-virus software on your scan server(s), and then you have to use commands on the filer to register it to one or more scan servers (I believe the "vscan" command on the filer was used for this. Sorry, I don't have access to verify that right now.) We set up a private 100MB/FD network between the filer and the scan server to use for scanning, and we did not see a significant performance hit when the scan server was enabled. If/when we take it into production, I'm hoping we can get a gigabit network in place for it, but even with only the 100mb nobody complained about performance problems. -- Mike Sphar - Sr Systems Administrator - Remedy, a BMC Software Company -----Original Message----- From: Jay Newton (Email) [mailto:jnewton@chkenergy.com] Sent: Tuesday, February 11, 2003 3:48 PM To: 'Steve Evans'; Wurster, Richard M DSTI; Pucky, Todd M.; toasters(a)mathworks.com Subject: RE: Real Time Virus Scanning with F820 and Norton AV Can you tell us why?

RE: using vol0
by Mike Sphar 11 Feb '03

11 Feb '03

I'm really curious what specific situations cause this, as I've had filers run out of space on vol0 lots of times and have never had a panic from it. The problem we have is that we just can't justify giving up three disks worth of data to hold the very tiny amount of data needed for booting. Our engineers are data hungry monsters, gobbling up as much space as they can, no matter how much space we provide. If it wasn't for occasionally running out of space, I'm not sure we'd ever be able to force them to delete stuff. -- Mike Sphar - Sr Systems Administrator - Remedy, a BMC Software Company -----Original Message----- From: Rune Bakken [mailto:rb@telenor.net] Sent: Tuesday, February 11, 2003 3:25 PM To: Charles Bartels Cc: toasters(a)mathworks.com Subject: Re: using vol0 Charles Bartels <cbartels(a)openharbor.com> writes: > Hi, > > I'm configuring an F810 and space is going to be a little tight.

Not sure if it is an issue, but I will never have any production data that keeps growing on vol0 again. I had a Filer panic once or twice because vol0 got filled up. I know some admins on this lists put static data that they control on with a qtree with fixed size (tree quota) on vol0. >>>>>>>>>>.rune -- Rune Bakken Senior System Administrator Telenor Business Solutions (Nextra), ManagedServices/*/IP-Services http://ips.telenor.net/
