RE: RAID Group Size Limits?

Why would DP cut your max raidsize in half? If anything, it should increase it, though I doubt Netapp allows it. Here's a quiz for everyone: Q: You have a fully loaded R200, 96TB, 24 shelves, 336 disks. You use a 2 disk root vol and want no more than 2 hot spares in the system. What raidsize do you use, so as not to end up with an inordinate number of spares? -----Original Message----- From: Hill, Aaron [mailto:aaron.hill@cba.com.au] Sent: Wed Jun 30 17:41:38 2004 To: 'James Brigman'; toasters(a)mathworks.com Subject: RE: RAID Group Size Limits? The absolute limit will depend on both your platform (FAS900 series, FAS250, R100, R150, R200 or F series) and ONTAP Version. Check the ONTAP release manual for your version. For example, 6.5 supports max of 28 for FAS900 & F series filers. I think this has been the same for quite a few releases. RAID DP cuts that in half.

How do you migrate from Novell to Netapp?
by Mike Langas 30 Jun '04

30 Jun '04

Greetings all, After a five year absence I find myself back in the NetApp world. I just convinced my employer to replace their aging novell servers with a netapp. Now the next logical question is how best to move the data? Does anyone know of a good way to migrate it all and keep ownership, permissions, etc... in place. Unfortunately I haven't been able to get the search facility for this list to work so I apologize if this question has been asked a million times before. Thanks for any help.

RE: Piecing together a netapp on the cheap - PART II
by Timothy Sesow 30 Jun '04

30 Jun '04

I have done Snapshots with EVMS (Enterprise Volume Management Software) under LINUX. It does basic snapshots and only has a command line interface (you do your own crontab). It is slower then NetApp snapshots (even more so the more snapshots you get), but it does work. You still have to figure out how to quiesce your filesystem during the snap (umount/mount works, but can be a challenge). The only thing close to SnapMirror I have found is to do RAID-1 via iSCSI or FCIP. Big investment in switches, though. Just have one local disk and more remote disk striped together under the "md" driver. The RAID striping isn't done in the shelf, the enclosure has a SES/CEMI card that gives the Filer information on temperatures, voltages, what power supplies are working, what the health of the local drive bus is, etc. This is either a SCSI target or a Fibre Channel port/WWN that the Filer talks to. The shelves are just JBODs and you can hook them up to any host you want and use them. It's just that when you hook them into the filer, the filer expects certain behaviors. You are on the right track on the IDE (I prefer the term ATA) drives, but the following issues present themselves: 1. LINUX has a 2TB file system limit. Solaris has a 1TB limit. NetApp has something like a 6TB limit. 96Tbytes is the most number of disk shelves (24) that can be hooked into that filer. I would much rather have 16 file systems with NetApp than 48 file systems with LINUX. 2. Getting LOTS of drives working all at once is a real challenge and starts to cost $$$ for more hardware (enclosures, SCSI/Fibre Channel interfaces, etc). The 7TB R200 is high on a $/MB basis ($.01 per MB), but a fully loaded R200 LISTS for half that per MB ($.006 per MB) and any reseller will give you a discount (maybe 20%) off that. The old R100/R150 have been discontinued (real pain to get those SCSI drive shelfs installed in the field). The R200 is easier to install/manage than the old R1x0. Plus MAXTOR doesn't make the old drive shelves anymore. I'm not saying that NetApp is always better, but they have their place in the overall scheme. Small NAS boxes are getting really good and NetApp is responding to the market that they choose to, which I would characterize as the "more fully featured solution" that has a higher return to NetApp. You might also want to look at http://www.openfiler.org. I have tried it and it has promise, but it is still a challenge. I still stick with RedHat 8 (yes, 8, not 9, cause 8 doesn't ever crash/hang) and just add in SAMBA 3.x for a really cheap NAS box. -----Original Message----- From: owner-toasters(a)mathworks.com on behalf of Joe Schmoe Sent: Mon 6/14/2004 12:26 PM To: toasters(a)mathworks.com Subject: Piecing together a netapp on the cheap - PART II Thanks for your help so far. Let me give some more details and answer some of the points you all have raised. First, I am looking for cheap and large - and am willing to sacrifice speed to get it. Second, I am very intrigued by SnapMirror (replication over WAN) and SnapShot copies (point in time backups). The reason I don't just build my own little unix fileservers with linux or FreeBSD is that I don't see how GNU tools and scripting can replicate the functionality of snapmirror and snapshot copies. Maybe I'm wrong ? So, I see that my initial plan is ill advised - you have pointed out that the disk shelves that NetApp ships are not just JABODs, but have intelligence in them - I did not know that the RAID striping was done in the shelf - I thought all RAID and logic was housed in the head unit and it just accessed big stacks of disks. So at this point, my questions are as follows: 1. Is there any reasonable implementation of snapmirror / snapshot copies in free UNIX OSs ? That is, can I get netapp like features out of a normal NFS fileserver ? 2. When I see netapp quote a certain capacity for its filers, like 96TB for the NearStore R200, does that simply mean that they can get to 96TB using the largest currently available IDE drives, and that once larger drives are available that number will naturally go up ? OR does it mean there is some logical limitation in place on the unit that will keep it from going above 96TB ? 3. What is the absolute cheapest IDE based NAS that netapp has put out ? Is it the NearStore R100 ? What if I bought the head unit and shelves from netapp (or netapp branded from ebay), but used my own 400gig hitachi IDE drives ? - I see a 7TB R100 on ebay right now for $78,500 - which is completely absurd. My 4TB freeBSD fileserver at home cost about $5k ... Again, many thanks. --------------------------------- Do you Yahoo!? Friends. Fun. Try the all-new Yahoo! Messenger

Change the /etc/syslog.conf and reduce the level of severity or disable the messaging of some services completely. There is a man page about this config file and there is a template file named /etc/syslog_conf_template (or so ...). Copy this template file to /etc/syslog.conf and edit it you will see the wished result. b.t.w. The "syslog(d)", "syslog.conf" man pages at ONTAP are in my humble opinion not the best. Have a look at the syslog.conf man page of any other unix derivate. It might help you more. :-) Just my 2 cents. Smile & regards! Dirk

Can passwords in LDAP be encrypted when being used for authentication?
by Matt Bailey 30 Jun '04

30 Jun '04

We have a 760 and are using an OpenLDAP database for authentication of CIFS clients. It only seems to work when the passwords are stored as clear text. This is an unacceptable security risk. It is disturbing enough to pass clear text passwords over the network. The /etc/passwd file should store DES hashed passwords so I was hoping that hashed passwords could be stored in LDAP. We are running in a workgroup with some Windows XP Home Edition so NT Domain and AD authentication are no good to us. Anyone else have this problem?

RE: DR project - SnapMirroring Oracle database
by Derek Lai 29 Jun '04

29 Jun '04

I have not gotten much response. Hopefully it is due to the timing of my Friday afternoon email. If you have done a DR project with Database and SnapMirroring, I'd love to hear about your experience. Over the weekend I just came across another big obstacle to using SnapMirroring - you can't cascade qtree SnapMirror! This one seems to be a very big restriction as it means wasting quite a bit of space to do things like backup and DR. Derek -----Original Message----- From: Derek Lai [mailto:Derek.Lai@onyxco.com] Sent: Friday, June 25, 2004 3:12 PM To: 'toasters(a)mathworks.com' Subject: DR project - SnapMirroring Oracle database I'm in the process of architecting a DR project for mirroring our production Oracle database and would love to hear from those who have done so already. We have been SnapMirroring the daily changes from one of our cluster F940 filer to the other for backup. In looking through the SnapMirror log I see that we are snapmirroring about 23GB of data on average. This is on a database of about 200GB total. We were thinking about using the max of the daily snapmirror number to size the pipe we need to the DR site. That is figuring to be a fair size pipe. Now our DBA is telling me that using Oracle's archive log they could just ship the logs to the remote site and play it back and achieve pretty much the same result. And the archive logs are averaging only about 4.5GB. That is 1/5 the size. It is fairly significant when you are shipping it half-way across the country! (We are in Foothill Ranch, CA and our DR site is in St. Louis). If that is true then management will probably choose to go with log shipping as opposed to SnapMirroring the data. I'm going through the data that we are SnapMirroring to figure out if there is something wrong with our setup. I think we are actually SnapMirroring the archive logs as well. Has anyone else been down this path? Any other ideas or suggestions? We are thinking that the log shipping method is going to involve alot more manual work and would like to avoid it if possible but we need to have good justification for that as well. Derek
