Migrating from NetApp to new NetApp
by Kelsey Cummings 25 May '00

25 May '00

I've got a f230 with 4 shelves of 4GB disks and its replacement, an f740. I talked to netapp support and they recommended that the best method to move the data from the f230 to the f740 would be to tapes with dump and restore. I can't believe that there isn't a more efficient way to do this. We are an ISP and all mail/ftp/http is served off of the netapp, any downtime will be painfull so we'd like to minimize it as best we can. What choices to migrate the data do we have? We've considered tar/cpio over nfs but that's going to take some time even if we migrate one service at a time. dump/restore seems clumsy. and plain ole 'cp' would take forever. Apparently there are issues with volcopy going from SCSI to FCAL, is that true? -- Kelsey Cummings - kgc(a)sonic.net sonic.net System Administrator 300 B Street, Ste 101 707.522.1000 (Voice) Santa Rosa, CA 95404 707.547.2199 (Fax) http://www.sonic.net/ Fingerprint = 7F 59 43 1B 44 8A 0D 57 91 08 73 73 7A 48 90 C5

Re: NIS problem with netgroup file
by Jagan Bearelly 25 May '00

Hi Cheryl, I am assuming you are using DNS. There should be case sensitive FQDN entry that matches the "nslookup" output for a given client and please see that dns.domainname is set with the same case sensitive value because "ypmatch" on NIS server is case sensitive. Also, ONTAP version 5.3.4R3 doesn't have a fix for netgroup related issue (19922 netgroup lookups can fail with fully qualified domain name). This fix is available in 5.3.5, 5.3.5R1 and 5.3.5R2 which are the latest releases. I hope that helps. Thank you.

Re: Migrating from NetApp to new NetApp
by Jay Sekora 25 May '00

I second other people's recommendations of rsync. rsync is great. There's another possibility, though, that has some of the same advantages. With rsync, you can do a preliminary copy that does everything while the system is live, and then schedule a hopefully short downtime to update just those things that have changed. Dump/restore should be able to do the same thing. While your filer is up and serving, dump/restore everything at level 0. (You can do this by rsh'ing the dump to the old filer and the restore to the new server, of course.) Then, when you have downtime scheduled, dump/restore at level 1 (making sure there were no intervening level 0 dumps). That way, you're only copying the changes, and the dump/restore will be much quicker. (Obviously, because you're going over the net, this is going to be slower than something like "vol copy". However, you can do the level 0 dump without interrupting service, so probably you only care about the time taken by the level 1 dump.) Basically, that amounts to doing by hand what rsync does automatically. Probably a bit more efficient than rsync (because less general). -j.

vol copy speed?
by Steve Losen 25 May '00

25 May '00

We have two F630s in a CF pair, with a total of 7 shelves of 9G drives. We are upgrading to 5.3.5R2P2 and adding 12 36G drives in 2 shelves. We have enough spare slots and spare disks in our existing 7 shelves to depopulate one shelf and leave us with 42 9G disks in 6 shelves 12 36G disks in 2 shelves We want to do some reshuffling of our shelves between the two filers. We plan to copy the following volume to a new volume consisting of 10 36G disks (leaving 2 hot spares). Filesystem kbytes used avail capacity Mounted on /vol/vol0/ 139160864 115462812 23698052 83% /vol/vol0/ /vol/vol0/.snapshot 34790216 12362380 22427836 36% /vol/vol0/.snapshot We are thinking about using vol copy and we would like to preserve all the snapshots. I think it would be faster to copy locally. However, we have 100Mb ethernet between the two filers, so would it be faster to hook up the shelves on different filers and vol copy across the net? If this copy can be done in under, say, 5 hours, we have the luxury of turning off NFS and CIFS and giving vol copy 100% of the CPU. We have to shut down both filers for OS upgrade, recabling shelves, etc., so downtime is inevitable. But if this copy is going to take over 5 hours, that's probably too long. Is there any information about how fast vol copy runs? Am I correct that vol copy does not require a special license? We figure that we have two options here 1) one lengthy downtime where we use vol copy during the downtime. 2) two shorter downtimes. In the first downtime we upgrade the OS and add the 36G shelves. Then we bring the filers back up and run a relatively slow dump/restore that loses snapshots. In the second downtime we run an incremental dump/restore and move the disk shelves to their final locations. If vol copy is "fast enough," option 1 would be easier and less disruptive than option 2.

Stale File Handles
by Jay Orr 25 May '00

AARRRGGHH!!! Ok, so I queried the list about this a year ago (early May '99) but am dealing with it again. Guy Harris was kind enough to help, and if you're out there I could use your help again. We had a power outage a week ago that shut down all our desktop systems - but not our filers and servers. Now, we have at random times during the day a large majority of systems griping : NFS write error on host hardrock: Stale NFS file handle. (file handle: 2ae0500 51356400 20000000 aa5c8 54417810 5c140000 2ae0500 51356400) They all have the same File handle, and the toaster has no error messages in its etc/messages files. I tried rebooting a few systems, but they still generate these error messages. I was trying to figure out what file it is by extracting an INODE number, but what Guy said before doesn't match : >In 5.0, we had to add a file system ID; file handles in 5.0 and later >consist of: > > 32-bit file ID for mount point > 32-bit generation count for mount point > 8-bit snapshot ID in which file resides > 8-bit unused byte > 32-bit file ID for file > 32-bit generation count for file > 32-bit volume ID for file > 32-bit file ID for export point > 32-bit combined snapshot ID and generation number for export > point; > the upper 8 bits of that 32-bit quantity are the snapshot ID > and the lower 24 bits are the generation number. > >The file's file ID (but not the mount point's or export point's file ID) >is *big-endian*; So, any ideas as to how to figure this out?

RE: Problem in Saving CDE Settings
by Schepers, Jan 25 May '00

25 May '00

Hello all, > I think it´s a problem with the permissions on your home > directory. The dtlogin process (CDE) reads > and writes configuration files in the > homedirectory (~/.dtlogin/..). The owner of the > process is root --> But root > has not permissions on mounted directories! When the problem is caused by a dtlogin process that tries to write as root to the users home directory, then we are talking about a CDE design error. The remedy for the problem lies in changing CDE in such a way that it uses the concerning user identity to read/write files to the users home directory. This is possible since it are divine powers that cause the problem. All other actions like opening up directories, exporting for root with or without subnet stuff are merely an intermediate solution.

Kelsey, Recently i migrated data (over 110GB) from F520 to F760. With a gig card insatlled in both the systems, we acheived 35GB per hour by using vol copy command. I am not sure about F230 taking a gig card. Alternately, you could use cpio for data transfer from any unix host. Its very efficient. I am acheiving 7GB per hour on regular network.

Re: software distribution with NDMPcopy/SnapMirror over WANs?
by Tor Lillqvist 25 May '00

25 May '00

> I believe "rsync" utility can help you out.... Definitely. FYI: Do not even consider rdist. In the common case of very small daily changes, rsync is one magnitude faster than rdist for replicating from one filer to another. (If lots of files change every day, the actual data transfer time will probably dominate, and the difference will not be that great.) Of course, SnapMirror is probably one magnitude faster than any replication using intermediate NFS clients such as rsync, as has other advantages as well... --tml

Oracle and NTAP.
by foo 25 May '00

25 May '00

Ok, so we've been contemplating using one of our 760's for Oracle storage. Discussions with Netapp people made me feel relatively warm and fuzzy about doing this but discussions with our DBA consultants didn't. Specifically they mentioned a situation they had experienced while testing a netapp/oracle environment which would cause total corruption and require restoration from backup. The specific situation is a case where the filer loses power but the DB server doesn't. Their claim is that if this occurs there is no method to recover the DB other than from backup. Anyone had any experience with Oracle/Netapp or this specific situation? We plan to test this in the next few days, but I wanted to get any insights you all might have. Thanks, -Brian

Does anyone have any experience with Time Navigator for backing up NetApps? I only just heard about the software yesterday, but they appear to support NDMP (clients for Solaris, AIX, Linux and NetApps). The company, Quadratec (www.quadratec-software.com), is only just entering into the North American market but they've been in the European market for awhile now.

F720 & AIT-2 tape drive
by Amy B. Caldwell 24 May '00

24 May '00

For all of you who graciously helped me with suggestions, I thought I'd write back with the results of our problem with our new F720 and the AIT-2 (Sony SDX-510C) tape drive so that everyone could benefit from our experience. The final justification from a NetApp engineer for why the AIT-2 drive would not work with our filer was due to insufficient cache on the F720's processor. Although we actually got a few complete backups using that tape drive, subsequent dumps would always fail until we got to the point (months later) that the filer itself would time out while talking to the tape drive at the beginning of a dump. We bought the filer February 2 and we got a DLT7000 tape drive on Monday, May 22, and now our problem is (supposedly) solved. We have had no problems with the DLT7000 so far (although it has less capacity -- and it's only been two days :-) ). We never tried the AIT-2 tape drive with any third party backup software. Thanks for your help! Amy Caldwell Texas A&M Nuclear Engineering

File-specific NDMP backups?
by Dave Toal 23 May '00

23 May '00

Folks, Another clueless-newbie question, as is my wont: I've got NetBackup 3.1.1GA running against a 740 filer with 5.2.1.P2. When I attempt an ndmp backup of a directory a few layers down in a /vol, it fails. Backups of the /vol itself work fine. /vol/brs1/prod/brs-data1/ger1 -- fails /vol/brs1 -- succeeds Is this an inherent limitation of ndmp at this rev level? I'd rather not set up nfs backups of these specific directories, but I'm not sure how else to do it. Dave -- Dave Toal Unix Dude Thomson & Thomson N. Quincy, MA

Interaction of /etc/hosts.equiv and telnet.hosts option
by Chris Thompson 22 May '00

22 May '00

I've just spent some time trying to work out why I couldn't rsh to our F740 from some newly installed machines even though I had added them to /etc/hosts.equiv. It turns out, apparently, that the option telnet.hosts list gets into the act: if the rsh'ing host isn't in the telnet.hosts list, then it gets a prompt rejection, and nothing is logged in /etc/messages; if it gets past that, then /etc/hosts.equiv is checked for host and (possibly implied) userid, and if *this* check fails then a "[rshd_0]: Permission denied to rsh request from ... at ..." is logged to /etc/messages. This is with 5.3.5. Has it always been like this? I could have sworn not, but the two lists have been in step here for a long time, so I could be wrong. There's nothing in the hosts.equiv(5), rshd(8), or options(1) man pages to suggest that telnet.hosts affects anything except telnet, or that rsh'ing is affected by anything except /etc/hosts.equiv. It also seems to me very counter-intuitive, and quite inconvenient because the telnet.hosts list is restricted to so few elements.

We also use OmniBack II to back up our F630 and F760, and I agree that it is inefficient across NFS and does not preserve ACL's. Netapp discusses several alternatives that use NDMP (Workstation Solutions "Quick Restore", Veritas and Legato). Though just as inefficient, an NT backup software would preserve the ACL's, though I don't know whether the restored data would have any unix permissions from a mixed qtree or not. ADSM has also been mentioned by some on this board. We are currently investigating alternative backup software, any recommendations or advice? >>> Philip Thomas <thomas(a)act.sps.mot.com> 05/22/00 11:30am >>> Yes, we use Omniback to backup our 540's & 330's across NFS for the last 5+ years. Of course, it's inefficient across NFS compared to having a "client" on filer like that for Legato and one would loose CIFS acls. -- Begin original message -- > From: "Uros Lampret" <uros.lampret(a)ourspace.si> > Date: Mon, 22 May 2000 09:03:22 +0200 > Subject: Omniback > To: <toasters(a)mathworks.com> > -- End original message -- ---philip thomas

The documentation can be found likewise, in an online "Changes to the System Administrator's Guide" for things that didn't make it into the Systems Administrator's Guide. The justification for the change was to provide more consistent access control (and "trusted.hosts" is an alias for "telnet.hosts", to help transition to the new meaning of the option). As Bruce points out, per-protocol access control is desired, and we have someone actively working on that. ...Tim Thompson...Network Appliance, Inc...
