routed
by Robert Borowicz 22 Feb '05

22 Feb '05

DOT 6.4.4 seems to want to run routed by default. Last reboot I missed the fact that it was turned on and now its running with a sizable route table. In my mind there is no reason to run the routed and take up memory space by the ensuing route list. Am I missing something obvious? -Rob

Destroying failed disks
by Ted Weston 22 Feb '05

22 Feb '05

Good Morning (or afternoon/evening, depending on your location) - I'd like to conduct a quick poll on the process those of you employ to destroy failed filer hard drives. Do you use an outside service to physically destroy it, utilize something akin to 'shred -z,' or an entirely different approach? Thanks, -t

RE: Destroying failed disks

Oops, sorry guys, lost track of the thread and wrote too soon. Of course! How the hell am I going to be able to sanitize a failed disk if it isn't even "seen" by the filer? The encrypted data option is still pretty good and it brings a bunch of security benefits (and additional administration). Otherwise, the industrial magnet sounds like great fun. I wonder what field strength and exposure time is required to guarantee a complete scramble? Hell it probably even depends on the angle that the disk platter is exposed to the magnet.

Quick access to quota information
by Jacek Nogala 21 Feb '05

21 Feb '05

The landscape: - The company is cable tv providing also Internet services - They intend to use FAS920 in NFS environment (all servers are Linux) - At this very moment they are servicing about 80k users but wanting to be able to service more that 200k - Services for users are to be implemented with UID and GID quotas Requirements: - They need to be able to retrieve quickly information about current quota usage for each specific UID or GID. - The information will be available via: -- Call Center - estimated queries 12 times per minute -- WEB GUI for users - estimated queries 120 times per minute - The quota information should be retrieved within 2 s and should be not older than 30 s - There is not specific requirements regarding method of getting the result (SNMP/RSH/NFS RPC/HTTP are acceptable) We discussed with them SNMPwalk and quota report parsing but they cannot accept it due to high and growing number of users. The most convenient way would be short series of SNMP queries for specific UID / GID. Any suggestions other than "make and parse quota report" are welcome. Best regards, Jacek

FC720 stalling
by Simon Waters 18 Feb '05

18 Feb '05

Okay - first post - be gentle. FC720 old and unloved, has finally started having issues where it ceases to handle CIFS request correctly. The problem manifests as a failure to respond to client requests. Two areas of possible "change" I think likely; Linux client mounting the CIF partitons. Wed Feb 16 11:57:57 GMT [de1]: CIFS t2 request 6 not implemented debuginfo( 15d 9e RH9CLIENT) Or the Windows clients finally being stable enough to stay up long enough to exhaust some resource (good riddance to NT4). In particular I'd be interested in seeing what the CIFS Session information looks like on other filers. I see a lot of repeats..... W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 0 W2KIISSERV (WINDOMAIN\iusr_anon - pcuser) 10 91 ... is that normal? However I have no clear handle on what is going wrong. The box just supplies CIFS service to a bunch of W2K webservers using IIS. The problem seems to manifest itself randomly, but does look like it is accumulating over time. Last time it managed 6 days. A reboot or restart of CIFS seems to clear it. When it happens nothing unusual is logged. The box is claiming to handle about 500,000 to 1,000,000 CIFS ops an hour. This doesn't seem to change much when the box fails?! All the status reports look normal. I guess it could be a networking issue, but it only affects the FC720, and is fixed by a reboot. We are in the process of sourcing replacement hardware because is has basically reached the end of it's life. Till recently it "just worked", so no one touched it, and as a result has archaic firmware 2.3_a2. If it was supported and with a future, I'd probably stick a firmware upgrade in straight away and see if this fixes it. But if anyone has any clues where to look, or what might be doing this....

problems with netapp snapshot backups
by Coder, James (STP) 18 Feb '05

18 Feb '05

We recently upgraded from a 960 NT cluster to a 980 cluster. Prior to this, the NT backups consisted of taking a snapshot and then backing this up to via CIFS using Veritas NetBackup. Since moving to the new cluster (and moving to DataOnTap 7.0) , we are unable to do this. The error we get is 12:01:54.350 AM: [5896.5736] <16> file_access::V_OpenForRead: ERR - CreateFile() failed: \\?\UNC\STPNAS01\VOL2BU$\~snapshot\backup\project3\QIT Admin\Project Ve locity\Release 5.1\TechnologyTeam\SoftwareInstallation\Windchill\OOTB\ptc\oracle \oo4o\CODEWIZ\DOC\HTML\WIZPROC.GIF (WIN32 5: Access is denied. ) Anyone seen / having similar problems? thx in advance. jcc James C.

George, We have safely deleted the entire contents of this directory on a number of occasions. Our original reason for doing so was because multiple autosupport send failures were causing the data to be accumulated for sending at a later date. The failures were mostly due to email attachment restrictions on our mailrelay. You may like to check your messages log around the time that weekly autosupports are due to go out. It is likely you will see something related to an SMTP failure.

RE: high performance file systems, non Netapp.
by Ben Rockwood 13 Feb '05

UFS (Solaris9/Solaris10) will cut it, but probly isn't the best without tuning, and definately not on Linux. If your using Linux, carefully consider JFS and XFS, both can do what you want but have up and downsides. Do NOT run ReiserFS in production, too many people have been bitten by it. EXT2/3 are just not even contenders, and who wants to pay for VxFS. For your requirements my first attempt (on Linux anyway) would be JFS. And, ZFS, btw, would handle this all nicely, but won't be introduced to Solaris10 untill Update1, sometime in the summer. benr. -----Original Message----- From: owner-toasters(a)mathworks.com on behalf of Maren S.

Yes, that may help on seeking and reading but the ammount of time required to delete 1Million files is still huge. I've not tested it though. I recall delete this kind of structure that squid would setup and it would take for ever. The application that is creating all these files is actually Mysql, and under UFS2 we got upto the limit of 1 million files in a single directory. Yes, it worked ok, but deleting the files took for ever. We are looking at hacking mysql so that it creates a directory tree. Still this only going to solve one part of the problem. The time required for dropping such databases or removing tables is long. We have use the more advance database format Innodb that Mysql offers as it is meant to be faster and it only uses one file per table instead of the default 3 files. > Maren> We are finding that file systems like UFS just don't cut it > Maren> never mind Linux extFS...

RE: Diskless Boot of Windows/iSCSI

This fits 1/2 the model, the key is that the base load never changes..if the end-user changes something that could have messed the encoding process up somehow, a simple reboot would repair it. To replace the base LUNs, I would have to copy from the snapshot, would take time to copy that file from snapshot space to real space, correct? Ive got Gig to the tent switch (clean workspace on refuel floor) and 100Mbit from there to the PCs. Performance should be in the OK range. The critical function for these PCs is encoding video, once loaded up network traffic for apps or I/O would be small. Also looking at some solutions that manage disk images that will always force clients to a base boot image on a reboot, but Id like to keep the technology layer thin, and I already have netapps in the design. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com]On Behalf Of Alan Biren Sent: Sunday, February 06, 2005 7:42 PM To: toasters(a)mathworks.com Subject: RE: Diskless Boot of Windows/iSCSI Jeff, As long as you have the base snapshot you can replace the boot LUNs quickly.

RE: Diskless Boot of Windows/iSCSI
by Derek Lai 09 Feb '05

We are looking at doing iSCSI boot of Windows for a different purpose - higher availability, maybe in place of clustering which is alot more expensive and complex. We have a production SQLServer which management does not feel is necessary to go through the complexity and cost to do a cluster. However, they are intersted in <30 min SLA. We currently have a spare server sitting around just in case. If we setup iSCSI boot of Windows then we can swap the spare server in place of the production server if the production server ever has hardware problem, right? Has anyone done this with one of the iSCSI accelerators? I've only setup for iSCSI with MS SW initiator. But I would imagine the iSCSI id would be fully contained on the iSCSI accelerator and if I remove it from one server and place into another server with the same configuration then the new server will just boot up as the original server?

Jeff, No sure if you have gotten additional answers. But you might want to look into writable LUN. It is a LUN based on snapshot and can be changed but at some point you can just throw it away and off goes all the changes. It is pretty quick to create the writable LUN.

Tracking fpolicy/vscan contribution to filer load
by Hill, Aaron 08 Feb '05

08 Feb '05

Does anyone have some information on where to look for information on vscan and fpolicy contribution to filer load over time? I would think that this would be available within the perfstat output or perhaps even the Filer Performance monitor (DFM Client performance agent). Any assistance on expected statistics would be helpful.

snaplocker utility with Veritas
by Bui, Marcus 08 Feb '05

08 Feb '05

Hi Toasters, I have an R200 with SnapLock Enterprise on ONTAP 6.5R2. A batch job runs every night to set the retention period against the data on a couple of WORM volume. The application that manages these data does not have the ability to set retention period, yet. Therefore, I have to run the Snaplocker.exe utility to manually set the retention period. The batch job as follow: snaplocker.exe \\Filer\volume <file:///\\Filer\volume%201h%203m%20\> 1h 3m /F << The /F switch is used because some files written/copied to the volume may already be 'read only'. The problem is with Veritas Netbackup Enterprise v4.5 incremental backup. All incremental backup is treated as a full backup since the batch job scans all files every time it runs. This somehow causes Veritas to think a file already there is a new/modified. And so, every backup job is a full. Any suggestions?

RE: F740 memory upgrade to lower CPU utilization?
by Bui, Marcus 08 Feb '05

08 Feb '05

John, More RAM will help, you can never have too much of it. These are the items to look for: 1. Are there any volumes > %90 full? Volume over %90 can degrade performance, especially on busy volume. 2. For cifs you can use "cifs top" command ( "cifs.per_client_stats.enable" must be on). These will show the top cifs clients ops. There's also one for NFS on NOW. 3. use "statit" command. This will provide a lot of very good information of what's going on. 4. If you have DFM v3.0 or higher, use the DFM client that comes with it. It's has a lot of good performance stats. As for the replacement upgrade, I suggest talk to your local Netapp. There are many things to take into consideration to make a good recommendation.
