Model is C760 (700 series). Netapp system board V. The problem is why the server accept only netcache license and not nfs license ?

RE: Solaris patch 118463-01, NetApp filers, and du
by Barnes, Simon 28 Jan '05

28 Jan '05

Hi Chris, Sorry it's taken me a while to reply. I'm very interested in your take on the Solaris 9 du patch, as I was instrumental in its creation. One of the customers I work with at NetApp had noticed that du returned a "cycle detected" error in Solaris 9, whereas it had not in Solaris 8. (Incidentally, I'm told Solaris 10 doesn't return this error either). With the help of my customer and Sun, we were able to identify the code change which had provoked this behaviour. As I understand it, Sun's patch does indeed, as you say, revert to the earlier Solaris 8-like behaviour, in that it ignores the error condition rather than fall over when it hits it. (Although Sun themselves are far better placed to comment than I am). This is what the customer in question wanted from the patch. Unfortunately I will be out of the office all of next week (back on 7th February), but I'd be happy to discuss this further with you when I return. My customer, I'm sure, would also be most interested to hear what you think of this solution, as so far he appears to be the only one to have reported this issue to us - unlikely as that sounds. Please feel free to drop me a line or give me a call. Regards, Simon.

Maybe I will have more luck here. A patch 118463-01 was released by Sun for Solaris 9 du(1) on 2004-12-06. It "fixes" 5068958 Solaris 9 du exits with "cycle detected" The description of this on SunSolve includes the following: | Description: | | Solaris 9 du exits with: | | du: failed for /: Cycle detected from XXX to XXX | | when a hardlink in the filesystem is detected. While at first sight | this seems reasonable behaviour due to the potentially harmful nature | of hardlinked directories, there is a genuine need to handle this in a more graceful way. | | One such example comes from using a NetApp File Server with snapshots. | The NetApp server exports snapshot heirarchies with file ids (aka | inode | numbers) which appear to be identical to existing directory file ids. | | While this is an implementation issue concerning the interaction | between Sun's NFS clients and NetApp File Servers, in the interests of | interoperability, the Solaris 9 du should simply ignore directories | with apparent duplicate inode numbers. I wonder what other users of Solaris in conjunction with NetApp filers think of this? Personally I thought the change in Solaris 9 was positively beneficial ... an error (even if obscurely expressed from the end-user's point of view) rather than a totally misleading result. It might have been useful if the patch had been to produce warning messages "I've seen this directory inode number before, I'm leaving this [snapshot] out of the space calculation altogether" and carry on with the rest of the tree. (One might think that this was what was implied by "simply ignore directories with apparent duplicate | inode numbers".) But it seems that it actually restores the Solaris 8-and-earlier behaviour, in which you get a total which is a naive sum over all snapshots, which is never (well, hardly ever) meaningful.

NFS hangs from linux clients
by Gil Freund 28 Jan '05

28 Jan '05

Hi, We have three Debian systems (two with 2.6.x Kernel and one with 2.4) using a NetApp 720 (6.5.3) as an NFS server. On two occasions in the last two weeks, when one of the Linux hosts tried to mount a file system from the netapp we got the error: Host nono not responding. (nono being the filer name) From that moment, no action could be preformed from any of the Linux hosts on the netapp. We see not errors in the log files of either the Linux nor the netapp. Other functions (CIFS, NIS and DNS lookups) continue with not issues. Attempting to stop and start the NFS service on the netapp did not have any effect, neither did rebooting the clients. The only workaround was rebooting the filer, after which all NFS operations resumed without a problem. I have started a trace on NFS, but did not get the same hangup yet. Did anyone encounter a similar situation, or alternatively can advise on where and what to check? Thanks Gil

Archiving, R200 and SnapVault.
by Ngoh, Clarence 28 Jan '05

28 Jan '05

G'day toaster folks, Our backups in Lidcombe are having issues completing its backups - the cause is yet unknown. As a result of our EOM backups not completing successfully, it is eating into our snapshot space. We have raised a case with NetApp and we are trying to isolate the root case of the problem. I am not after suggestions to fix this at the moment. Rather ... We have just purchased a R200 for achiving purpose and we are thinking of utilising this to alleviate the issue we are having. We wish to dump some of the EOMs to this box and backup to tape when we resolve the backup issue. Our scenario is common ... A production site and a DR site. We backup our EOMs at the DR site. We are wondering if the process is as simple of copying over the EOM snapshots from the DR filer to the R200 via SnapVault and configuring our backups (Veritas NetBackup) to backup from the R200 to cassette. Question : From what I have read, backups to cassette can be done straight from the R200. Any real life experiences to share? Are they any caveats that we should be aware of? Sorry if this question seems somewhat simple -- I am still ploughing through a pile of whitepapers at the moment, but because this issue is somewhat urgent, any suggestions would be much appreciated.

SNMP CPU queries suddenly returning zero
by Gavin Kelman 27 Jan '05

27 Jan '05

Hi, I recently started graphing CPU busy time with SNMP and it worked fine for a few weeks, and then all of sudden one day, it always returned 0 and has done ever since. I suspect rebooting the filer would bring the SNMP CPU reading back to life, but I was wondering if anyone had a better idea... I'm running NetApp Release 6.5.2R1P9 on an F940 and using the following command to get the information: snmpget netapp public -m NETWORK-APPLIANCE-MIB.txt \ NETWORK-APPLIANCE-MIB::cpuBusyTimePerCent.0 Telneting to the filer and running "sysstat" returns normal (non-zero) CPU usage information. Ideas? Cheers, Gavin. -- Gavin Kelman gavin(a)metahusky.net
