find busiest flexvols in an aggregate?
by Mopar Guy 30 Jun '07

30 Jun '07

we have many flexvols in a large aggregate. our filer 960C is always 100% cpu and about 11,000 to 18,000 nfs ops/sec. some people have started complaining about performance. how can we tell what flexvols may be overutilized or consuming most of the traffic so we can perhaps migrate them elsewhere? also we only have two fibre loops with 7 shelves on each loop, if we added a third and split them down to about 4 shelves or so per loop would that improve i/o?

Odd problem since upgrade to FAS6030
by Warkentin, Grant 29 Jun '07

29 Jun '07

We recently upgraded to a FAS6030 running 7.2.2. Since the upgrade our developers (they run VMWare Workstation 5.5) have been complaining that the connection to their H: drives is dropping. They receive a message about "You are now in off-line mode". When the filer is pinged, it does respond and the H: drive will reconnect eventually. The regular work stations are having no problems with this. Only the VMWare users. Have not been able to find any relevant docs in a Google search yet... Thought I'd post here in case someone has seen this. Thanks.

Scsi sense check/tape backup errors.
by Ken Williams 29 Jun '07

29 Jun '07

So I have an FAS3020 running 7.0.2 It has been repurposed to handle production data and as such we need to back it up. I've attached a DLT8000 tape drive to is via SAN (fiber->scsi bridge), and ontap sees the tape: Tape drive (em2dir1:2-26.146L4) Quantum DLT8000 rst4l - rewind device, format is: 81633 bpi 40GB cmp DLTIV nrst4l - no rewind device, format is: 81633 bpi 40GB cmp DLTIV urst4l - unload/reload device, format is: 81633 bpi 40GB cmp DLTIV rst4m - rewind device, format is: 85937 bpi 70GB cmp DLTIV nrst4m - no rewind device, format is: 85937 bpi 70GB cmp DLTIV urst4m - unload/reload device, format is: 85937 bpi 70GB cmp DLTIV rst4h - rewind device, format is: 98250 bpi 40GB DLTIV nrst4h - no rewind device, format is: 98250 bpi 40GB DLTIV urst4h - unload/reload device, format is: 98250 bpi 40GB DLTIV rst4a - rewind device, format is: 98250 bpi 80GB cmp DLTIV nrst4a - no rewind device, format is: 98250 bpi 80GB cmp DLTIV urst4a - unload/reload device, format is: 98250 bpi 80GB cmp DLTIV There is media in said tape, it is NOT write protected, and I've tried other media as well as other tape drivers (I actually have 4 DLT8000 drives assigned to the machine) Whenever I try to dump data to tape manually : dump 0f nrst4a /vol/vol0/etc ...

Cifsconfig_share.cfg
by Jon Hill 29 Jun '07

29 Jun '07

We need to replicate the definitions for all cifs shares of files from a particular volume to our DR filer. For the moment I'm probably going to manually copy all the relevant lines from etc/cifsconfig_share.cfg on the production filer and paste it into the corresponding file on the DR filer, but I'm a little concerned by occasional groups of 6-8 rows of hash marks / pound signs (#) I see scattered throughout the file. Does anyone know what these represent? I was thinking maybe onTAP deletes old shares by replacing their relevant lines in cifsconfig_share.cfg with #s, but that seems like an ugly way to achieve the goal.

Snapvault:
by Francois Joubert 28 Jun '07

28 Jun '07

I have a number of volumes/qtrees on my primary filer. I am busy setting up snapvault on a secondary filer (both have an equal number of disks available to them). I was wondering which might be better in practice: a one-to-one relationship of volumes and qtrees on the primary and secondary; or to create the requisite number of qtrees on the secondary inside a single large volume. At the moment, I have 8Tbytes configured (4 volumes, 2 aggregates) on the primary (including snap reserve). I have about 5.5Tbytes of data to migrate onto the primary filer.

RE: ISCSI Bridge
by Forest Leonard 27 Jun '07

27 Jun '07

I thought that SCSI to ISCI bridge would be cheaper, just not sure if it would work. I also have no FC switches. I was hoping to share the tape drive with the 2 heads of the filer (not sure if that is possible.) Thanks, Forest -----Original Message----- From: Darren Soothill [mailto:darren@soothill.com] Sent: Wednesday, June 27, 2007 12:55 PM To: Forest Leonard Subject: RE: ISCSI Bridge Why not get a SCSI to FC bridge then? It will be faster then puling all the data across ethernet especially if you have larger files on the filer. The other option is 3 way NDMP but that is not supported by a large number of backup products.

Symlinks and CIFS, FTP (and NFS)
by Francois Joubert 27 Jun '07

27 Jun '07

I would like to manage the symlinks in use for the whole company at a certain directory depth on our filers (FAS3050 + OnTap 7.2.2). I would like to create the following setup so that users see a single share when they browse the filer via CIFS and FTP but give them access to data spread over more than 1 aggregate, volume and qtree. Filer_1 ======= Aggregate_1 Data_volume_1 Qtree_1 All_data (single share visible to company) Real_dir_1 Symlnk_Real_dir_2 Symlnk_Real_dir_3 Symlnk_Real_dir_4 Aggregate_2 Data_volume_2 Qtree_2 Real_dir_2 Data_volume_3 Qtree_3 Real_dir_3 Data_volume_4 Qtree_4 Real_dir_4 I am aware that I need to configure the widelinks option. How do I create the symlinks from my admin host (FreeBSD) which mounts all the volumes over NFS for data management purposes? I don't want to use a Windows machine to create the links. My users are Win2K and MacOSX clients and access their data using CIFS and FTP (NFS may be used later). I have a number of samba servers with this data directory setup as a single share visible to users but data spread over a number of disks. I use the unix "ln -s" command to create the necessary symlinks on the samba servers. Feel free to point out what may be glaringly obvious. Thanks Francois
