DFM migration.
by Jeff Cleverley 06 Mar '12

06 Mar '12

Greetings, I need to change the hardware and OS for my current 3.7 DFM server. I've set up another box with the new OS and installed the 4.0.2 release. I have successfully imported (AFAIK) a copy of the old database. I am not the primary user of DFM and would like to have the primary user be able to do some testing and looking around before trying to make a more permanent switch. My concern is having 2 instances of DFM trying to run backups, purge snapshots, etc. The new host name is not listed in hosts.equiv and it doesn't have ssh keys on filers. There are no entries for the ndmp credentials. Will having 2 of these online cause a problem? If so, what is the best way to have the second one online in more of a read-only/browse type mode? For those who will ask, I'm not going straight to OnCommand yet because I don't know enough about it yet. There are also several packages that seem to only run on Windows, and some that mention only running on 32 bit OS and hardware. We are primarily a linux lab and I don't want to have to set up a Windows server or have to go to Goodwill and try to find a 32 bit server :-) Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

Experience with Backup Software using NDMP
by Steffen Knauf 04 Mar '12

04 Mar '12

Hi Toasters, we consider to buy a new Backup Software and i don't know whats the best Software. Now, we are using Netvault (vian ndmp)but it don't works very well (e.g. problems with deduplication.....). We backup ~ 10 TB via NDMP to a LTO 5 Tapelibrary. Perhaps someone have experience with other Backup Software. Netvault sucks generally ;( greets Steffen

max directory depth and max dir size
by Nicholas Bernstein 02 Mar '12

02 Mar '12

Maybe I'm just being an idiot, but I couldn't seem to find best practices that describe max directory depth and size. I know anecdotally directories shouldn't be larger than 10mb (the directory itself, not the contents) but I can't seem to find an official best practice guide that has these. Can anyone point me to the right doc? Thanks in advance, Nick

backing up a small toaster
by Tom Yates 02 Mar '12

02 Mar '12

Is there anyone out there backing up a toaster *not* using a commercial NDMP-compliant product (eg, Netbackup)? How do you do it? Do I have any options besides (a) direct-attach a dedicated tape drive or (b) commercial NDMP-enabled software, which will enable me to get both UNIX-specific information and CIFS-specific information onto tape safely? Thanks for any light anyone can shed. -- Tom Yates - http://www.teaparty.net

snapshot bolus after re-enabling de-dup
by Fletcher Cocquyt 01 Mar '12

01 Mar '12

We re-enabled dedup on one of our volumes yesterday and observed the 'df-sh' savings go from 20% to 37% (yay!) but the volume usage jumped up snap list revealed a big delta from our usual nightly snapshot delta: > snap list vm65net Volume vm65net working... %/used %/total date name ---------- ---------- ------------ -------- 0% ( 0%) 0% ( 0%) Mar 01 13:47 irt-na03(1573989836)_vm65net.450 (snapmirror) 37% (37%) 27% (27%) Mar 01 00:00 nightly.0 39% ( 4%) 29% ( 2%) Feb 29 00:00 nightly.1 41% ( 5%) 32% ( 2%) Feb 28 00:00 nightly.2 42% ( 4%) 33% ( 2%) Feb 27 00:01 nightly.3 43% ( 4%) 35% ( 2%) Feb 26 00:00 nightly.4 44% ( 4%) 37% ( 2%) Feb 25 00:00 nightly.5 45% ( 4%) 39% ( 2%) Feb 24 00:00 nightly.6 Is this expected behavior? (when I noted these observations I was asked "doesn't dedup work on the snapshots too?") thanks Fletcher

Snapdrive failing to create a flexclone but only on Sundays. Works fine every other day of the week.
by Dan Finn 27 Feb '12

27 Feb '12

Long story short we have a clone of our production database that we refresh and remount on a linux server every night. This is a script that is being called from cron. We recently converted the server that runs this script from a physical server to a vmware vm. Since we have done that this refresh process has failed the past 3 sunday nights. It runs every single night and it runs without errors every other night. There's not much to the script, here's the command that creates the flex clone: snapdrive snap connect -lun log/disk disk_$LUN -snapname filer:/vol/database_volume/log/disk:$SNAPNAME them we mount the flex clone that is create via iSCSI. The error that is being reported by the script is: 385 connecting filer:/vol/database_volume/log/disk: 386 creating unrestricted volume clone filer:/vol/clone_volume ... failure 387 0002-098 Admin error: Failed to create volume clone clone_volume on filer filer : The volume is not currently available The error from the sd-trace.log: 173338 00:30:54 02/26/12 [f7f61b90]i,2,18,FilerZephyr::volume_clone_create: zapi filer root "" volume-clone-create parent-snapsho t daily-2012-02-26 parent-volume database_volume space-reserve none volume planningdb_rootdb_log 173339 00:30:54 02/26/12 [f7f61b90]i,2,18,FilerZephyr::volume_clone_create in = <volume-clone-create> 173340 <parent-volume>database_volume</parent-volume> 173341 <parent-snapshot>daily-2012-02-26</parent-snapshot> 173342 <volume>clone_volume</volume> 173343 <space-reserve>none</space-reserve> 173344 </volume-clone-create> 173345 173346 00:30:54 02/26/12 [f7f61b90]i,2,18,FilerZephyr::output in = <results reason="The volume is not currently available" statu s="failed" errno="13156"/> 173347 173348 00:30:54 02/26/12 [f7f61b90]E,2,18,FilerZephyr:: (filer) volume-clone-create failed, error: 13156: The volume is not currently available And then what's odd is if you look at the messages file on the filer, it's reporting as if the clone was successfully created: Sun Feb 26 00:29:28 MST [filer: wafl.snap.delete:info]: Snapshot copy 2012-02-24 07_00_27 daily_filer_database_volume.-.log on volume database_volume NetApp was deleted by the Data ONTAP function zapi_snapshot_delete.

Sun Feb 26 00:30:56 MST [filer: lun.newLocation.offline:warning]: LUN /vol/clone_volume/log/disk has been taken offline to prevent map conflicts after a copy or move operation. Sun Feb 26 00:30:56 MST [filer: lun.map:info]: LUN /vol/clone_volume/disk was mapped to initiator group linux-server.domain.com_iscsi_SdIg=0 The only thing I'm wondering is if that zapi_snapshot_delete that is happening 1 second before could be causing an issue however I looked at the logs from the past sunday failure and that zapi_snapshot_delete did not happen at the same time so I'm not sure that's the issue. Any help would be really appreciated. Thanks, Dan

bypassed disks - whats the deal?
by Fletcher Cocquyt 26 Feb '12

26 Feb '12

We've discovered a couple of these bypassed disk conditions via the flashing amber light - but this was noticed totally out of band with normal support Each time we opened a case manually and Netapp immediately sent out a disk replacement. So why is a bypassed disk not treated as a failed disk ? This kind of silent failure (in terms of Netapp monitoring and alerts) in a lights out datacenter seems negligent. Message logged on syslog server: esh.bypass.err.disk:error]: Disk 4d.49 on channels 4d/PARTNER disk shelf ID 3 ESH A bay 1 Bypassed due to the drive self bypass. BTW: I read the KB article on bypassed disks and ran the CMD to highlight BYP but it did not show BYP https://kb.netapp.com/support/index?page=content&id=3012395 thanks, Fletcher

migrating vol0 (root) to new aggr
by Fletcher Cocquyt 23 Feb '12

23 Feb '12

Hola guru's I've done the steps to migrate vol0 from aggr0 to aggr1 from: https://communities.netapp.com/thread/11439 vol restrict newroot vol copy start -S root newroot vol online newroot vol options newroot root # aggr options root is from maintenance mode...when done here the aggregate containing newroot will become root since it has the root volume. vol status # confirm newroot is "diskroot" reboot vol status # confirm newroot is now root vol offline root vol destroy root vol rename newroot root -- and am about to reboot Is it necessary to do the aggr options aggr1 root Or only if on reboot ontap can't find the root vol0 on aggr1? thanks Fletcher

scsi.cmd.abortedByHost:err
by Stuart Kendrick 23 Feb '12

23 Feb '12

Is this telling me that the HBA in the filer ('toaster-a') aborted the SCSI command? Or that the port on the back-end storage (a 3Par T800) aborted the command?

RE: upgrade a FAS980 with 10GB network cards possible?

The FAS30xx series do. It is a single port card.
