7.2.6.1 P2-P8?
by David N. Blank-Edelman 13 Aug '09

13 Aug '09

Hi- We recently had a crash due to bug #327361 (quotas not play nice with CIFS alternate streams). This is apparently fixed by P2. A quick check on now.netapp.com shows they are now up to P8 with what looks like a number of less than great bugs fixed in the releases later than P2 as well. Netapp support recommends we go to P2 because that is all we strictly need but suggests there would likely be no problem going all the way to P8 if we want. Has anyone had any experiences with either P2 or P8 (or any number in between) that would suggest we should pick one over the other? Thanks! -- dNb

CIFS volume deduplication
by Davies,Matt 10 Aug '09

10 Aug '09

Hi everyone, We have a NetApp Filer 3040 running 7.2.6.1. We have configured Dedupe on a few volumes with ESX VM's and have saved about 15-25% disk space. Last week, we ran it on our CIFS Volume (Homedir, Shared Drives, etc), which is 950Gigs, but we only saved about 700 megs. These are the following commands we used to start the deduplication... sis on VOL sis start -s VOL It took about 8 hours to scan the volume. Afterwards, "df -s" showed that it saved 0%. Netapp suggested that I wait for the old snapshots to delete, but it still didn't help. Does anyone have any ideas about this ?

User based Quotas - Why don't they show up correctly when mapped?
by Langdon, Laughlin T. (Lock) 07 Aug '09

07 Aug '09

More fun with user based quotas. When a user has a mapped CIFS share to their home drive the size of the entire volume shows up when they map the drive. I thought user quotas used to just show the "quotaed" space for that user. I.E. I have a 11TB volume. I create a user quota of 500MB and apply it to a user (say xyz99). When XYZ99's home share is mapped they see 11TB available to them, not 500MB. A tree based quota with a hard limit works just fine in showing only 500MB available. I've worked with Netapp support and did get an obscure bug (88541 <http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=88541> ) that has no information and a reply that there isn't much information on this issue. (Maybe the functionality just isn't there? I could swear we used to have that function.) Does anyone use user quotas and have this same problem? Are there better ways to do user home share type CIFS shares? Thanks lock p.s.

Yep we use na_ntfschown as well. I will setup some test shares to test your setup.

There is a tool in the Toolchest on the NOW site called na_chstuff. Within it is one called na_chmod.exe I have a script that I run at 3am every day that uses this to change the ownership of each folder based on the users' login name. We have our user shares saved as filername:/vol/users/username and shared as \\filername\users. They are using NTFS security style and no QTrees. Authenticated Users has List on the first level subfolders with Administrators, System, and Creator Owner having Full Control of everything. The script is something like (I'm at home and doing this off the top of my head): for /d %f in (\\filername\users\*.*) do na_ntfschown /r domain\%f The exact syntax may be off a bit, but you get the idea.

Re: Hanging NDMP backup sessions?
by John Stoffel 17 Jul '09

17 Jul '09

Patrick> There is a known bug regarding hanging NDMP sessions and this Patrick> ontap version. Upgrade to the P2 version and your issue Patrick> should be resolved Thanks for the info, though in my case I'm not sure if that's completely the issue, since it looks like the NDMP session(s) tend to go away properly, but the backup sessions don't terminate properly, which leads to NDMP failures when they can't allocate new backup sessions. In any case, I'll login to NOW and see what I can find in terms of the changes between 7.2.6.1 and 7.2.6.1P2 that relate to NDMP. Thanks! John

Hanging NDMP backup sessions?
by John Stoffel 17 Jul '09

17 Jul '09

Hi all, Is anyone else seeing hanging backup sessions under 7.2.6.1 when doing NDMP backups to a directly attached FC LTO4 tape drives, using CommVault 7.0.0 Update 76 Version #### software? For example: > ndmpd status ndmpd ON. Session: 79 Active version: 4 Operating on behalf of primary host. tape device: not open mover state: Idle data state: Idle data operation: None > backup status ID State Type Device Start Date Level Path -- ----------- ---- ------ ------------ ----- --------------- 0 RESERVED NDMP 1 RESERVED NDMP 2 RESERVED NDMP 3 RESERVED NDMP 4 RESERVED NDMP 5 RESERVED NDMP 6 RESERVED NDMP 7 RESERVED NDMP 8 RESERVED NDMP 9 RESERVED NDMP 10 RESERVED NDMP 11 RESERVED NDMP 12 RESERVED NDMP 13 RESERVED NDMP 14 RESERVED NDMP 15 RESERVED NDMP 16 RESERVED NDMP 17 RESERVED NDMP 18 RESERVED NDMP 19 RESERVED NDMP 20 RESERVED NDMP 21 RESERVED NDMP 22 RESERVED NDMP 23 RESERVED NDMP 24 RESERVED NDMP 25 RESERVED NDMP 26 RESERVED NDMP 27 RESERVED NDMP Now I know I can just do: > backup terminate # to cleanup these sessions, but I'm wondering why I'm seeing them in the first place, esp since my other sites running the same software and OSes aren't seing these issues, or at least not to as great a degree. It could be that I've mis-configured CommVault somehow...

Mounting VMware Volume Snapshot on Windows Host
by Skip Norman 10 Jul '09

10 Jul '09

I have a windows 2003 server with Snapdrive 4.2.1 and I was wondering how I can mount a snapshot of a volume that holds vmware luns. Is this possible? I was told that this is feasible with VCB framework installed; however, I currently receive an error: "unable to connect disk. Failure in connecting to the virtual disk. Error: A timeout of 600 secs elapsed while waiting for the volume arrival notification from the operating system". I have verified that I can mount exchange volume snapshots for SMBR recovery on this machine. Also, what are others here doing for image level backups of their VM's? Are there better/cheaper alternatives to VCB and SMVI? How is SMVI working out for those of you out there using it? Thanks.

Strange data loss on a Netapp NFS volume
by Straub Ciaran 07 Jul '09

07 Jul '09

Hi Tosters, Has any one ever encountered a strange data loss on a Netapp NFS volume? Last Sunday there was an incident Production of my customer was down as 2 Oracle database was gone form the volume. The Netapp was not serving the database to the application server. There should never be a Full volume or Full aggr, but things happen we all know Mr. Murphy law. The volume did reach maximum size at some point, and there was a hanging snapmirror.
