RE: NetApp 3050 vs Dell 6650
by Carter K. George 29 Oct '05

29 Oct '05

I am sure the FAS 3050 is a fine solution and yes, FlexVols are cool, but NFS on Linux is nowhere near as bad as you make it out to be. On current distributions (SuSE SLES9 - which has the better Linux NFS - and RHEL) both UDP and TCP are supported and work just fine. There was some trouble with older 2.4 Linux kernels with TCP, but that's long since fixed. rsize and wsize up to 32768 is also supported on both UDP and TCP, at least on SuSE Linux. And Jumbo frames work just fine on Linux NFS, as some of our benchmarks show (we have now gotten over 2,000 Megabytes (not Megabits) per second over NFS from a single Linux file system, read and write, using iozone). That's using a cluster file system to mount and export the same file system from multiple Linux nodes concurrently. With jumbo frames and two standard GigE ports, you get about 225 MB/sec per node. Need more bandwidth to/from a given file or file system? Just add more nodes. It is true that the NFSv4 server is not entirely mainstream on Linux yet. The NFSv4 client and server are both being developed at the University of Michigan, Center for Information Technology Integration, with funding from Network Appliance, PolyServe, and IBM. You can track the progress here: http://www.citi.umich.edu/projects/nfsv4/ While v4 might not be a standard part of the enterprise distributions yet, this code runs, it passes interoperability tests with other NFSv4 implementations at the NFSv4 Bakeathons, and you can download it and run it for free on any Linux server with a suitable kernel. It may well be behind the NetApp implementation, but it is not in its infancy and in fact, NetApps has been very generous with both people and money in supporting the development and testing of NFS v4 on Linux. ckg -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Tim Sent: Friday, October 28, 2005 4:08 PM To: Blake Golliher Cc: ChazzCRH; toasters(a)mathworks.com Subject: Re: NetApp 3050 vs Dell 6650 From a performance and stability standpoint, as I recall, the RHEL3 NFS server only supports NFS over UDP reliably and only with a max rsize/wsize of 8192.

perfstat for macosx

Would anyone be intersted in my patch for macosx to run on Darwin? I'm still adding to it, but the patch works, and runs as is. It's fairly straight forward to see what I did, but it might save you the typing. I'll include it with this email. -Blake

NetApp 3050 vs Dell 6650
by ChazzCRH (sent by Nabble.com) 28 Oct '05

28 Oct '05

We are considering replacing our current NFS server which is a Dell 6650 with Quad Xeon MP 2.7 procs, 12GB RAM, 4GB NICS running RHEL3 with a 3050 cluster. We are running 7.2K SATA drives from Winchester Systems connected via an U320 SCSI to the Dell today and we would be running NetApp's 250GB SATA drives on the 3050 cluster. NetApp posts IOPS as a performance metric but I am unable to find anything like that related to my Dell configuration so trying to figure out the performance gain and justifying the money we would be saving is becoming very tough. I can look at reads and writes per sec using IOSTAT on my Dell but I am not 100% sure its apples to apples compared to IOPS. Can anyone shed some light on this for me?

RE: NDMP Copy for windows..
by Pou Lee 27 Oct '05

27 Oct '05

From archived email messages I have ascertained that the F760 was running DOT 6.0.1R3 that at that time (3/2004) was only shown as "earlier releases" on NOW, not in the active supported version list. NDMPcopy did not work via either push or pull between the F760 running DOT 6.0.1R3 and the FAS250 running 6.5 since no client existed in DOT 6.0.1R3 or version compatibility issue. Options at that time were: 1. Upgrade first to 6.2 then to 6.5 2. Use NT/W2K (AS) Java NDMP copy client running on NT 4 workstation (there was a Net App PS internal tech guide on this process) 3. Use "volcopy", copying whole volume; requires complete downtime (10 - 20 hours pending on number of network interfaces and their speeds; could add Fiber GigE for connection to Copper GigE on FAS 250 if a swtich supporting both Fiber and copper is available) 4. Use third party remote data replication software like "Secure Copy", "Robo Copy" for Windows data and "rsync" for UNIX data; requires long time (20 -30 hours) and two different processes for the two types of data Option 1 was deemed problematic since two upgrades are involved so more could go wrong potentially Option 2 was chosen and executed with no problem. Option 3 & 4 were not recommended due to long outage. -----Original Message----- From: Tim [mailto:tmacmd@gmail.com] Sent: Thursday, October 27, 2005 3:40 AM To: Pou Lee Cc: Jeff Mohler; Toasters List Subject: Re: NDMP Copy for windows..

Trend-Micro VSCAN disabling access to Users' Home Directory !
by Rafailov, Elman 27 Oct '05

27 Oct '05

Hi All, Has anyone been using / experiencing issues running trend-micro VSCAN on the filers. We are running an FAS270C netapp SAN. We have a flexible volume called home_directory w/ two subfolders: users and profiles to host our users' home directory. We are also hosting the groups directory on the filer, exchange databases, sql databases and a bunch of other cifs shares. Yesterday, late afternoon - users' were prevented from accessing their home direcories. They would get an hour glass and their computer would freeze. There was no impact on the groups directory, exchange or sql or any other cifs/luns except for the home directory. As soon as i disabled vscan on the filer, users were once again able to access the home directory. I have since kept vscan off until i can figure why this happened. Any advise would be appreciated.

Jeff, You might want to check with your Net App Sales account manager to see if they can get you a copy of NDMP Java client from Net App Professional Service. We have used the NDMP Java W2K client for migration from a FAS760 running DOT 6.2 to a FAS250 running DOT 6.5 since DOT 6.2 does not support NDMP (if I recall correctly) so we had to be creative. If you need to migrate data from Windows servers to Net App filers, you might also want to consider OSSV (Open Systems Snap Vault). We have used OSSV successfully in multiple instances migrating data from W2K AS servers to R200's with assistance from Net App Professional Services after engaging Sales account manager.

UNCLASSIFIED Also check the NDMP version level that Arcserve is set at. Most backup software, with exception of Syncsort Backup Express v2.2.x, will only work up to NDMP v3. NetApp DOT v6.4 and above default to v4. Basically, when first tape is done filer is sending v4 status command to Arcserve stating EOT and request new tape mount, v3 backup software doesn't understand command and plays dumb, eventually filer will time out waiting for new tape and responds with a tape failure message. You need to change ndmp setting of filer to NDMP maxversion level of 3. >ndmpd version 3 Use command without version number to display current setting.

Re: Formatting disks
by Tim 18 Oct '05

18 Oct '05

If you are running a current enough ONTAP release, you can go into maintenace mode and do a "scsi format disk id" and see what happens. I highly doubt that will fix it as there is something else seriously wrong with the disk. Almost always, if ONTAP can't spin it up after a fresh wiping of the disks, then the disk is likely bad. --tmac Blake Golliher wrote: > Are they just showing up as failed right now?

RE: Monday morning Question - NTFS ACL resetting.
by Warkentin, Grant 17 Oct '05

17 Oct '05

Thanks - couldn't change ownership at all Security tab missing for folder in explorer - ntfschown, cacls, xcacls and doing an rm (as filer root with "priv set advanced" on) all wouldn't work. Did find a workaround - Created at new home folder for the user and copied all his files to it. After he disconnected, I was able to rename the original home folder. The rename did something as I was then able to delete the problem folder afterwards. Never seen this happen before.

Airflow in DS14 shelf if disk removed
by Chris Thompson 13 Oct '05

13 Oct '05

We had a failure of a disk in our DS14 shelf (attached to an F810) last night. All the automatic shipping of a replacement seems to be working fine. However, if one leaves the failed disk in the shelf while waiting for the replacement, then every few hours one gets a message like Wed Oct 12 10:00:00 BST [raid.fdr.reminder:warning]: Failed Disk 8b.22 Shelf 1 Bay 6 [NETAPP X272_SCHT6073F10 NA06] S/N [3HZ171ZR000073420TXM] is still present in the system and should be removed. But I am concerned that actually removing the disk with its carrier would leave the airflow through the shelf unbalanced. I have compromised by disenganging the disk from the shelf but leaving it sitting in the slot, sticking out just a little. What do others do in in this situation? Maybe you all have dummy carriers to block vacant slots? -- Chris Thompson Email: cet1(a)cam.ac.uk

We had a disk in a ds14 cause a 960 cluster to fail due to noise on the buss. Air flow is not my main concern. Pull the puppy as soon as practical. jc James C.
