SMVI "Operation timed out" during queice / vmware-level snapshot
by Ken Williams 20 May '09

20 May '09

Anyone seeing these types of issues? I have a FAS3070 cluster serving VMFS datastore over fiber channel to a 6 server cluster of ESX 3.5 latest SP. I seem to get a couple VMs (randomly) that are unable to perform the VMWare snapshot and cause the snapshot to fail. The problem seems to be hit or miss. Here's an excerpt from the log: 2009-05-19 19:18:47,556 INFO - FLOW-11012: Operation requested retry 2009-05-19 19:18:57,681 INFO - FLOW-11006: Starting operation in threadpool backup 2009-05-19 19:18:57,697 INFO - FLOW-11012: Operation requested retry 2009-05-19 19:19:07,822 INFO - FLOW-11006: Starting operation in threadpool backup 2009-05-19 19:19:07,837 WARN - VMware Task "CreateSnapshot_Task" for entity "snqfpapp01" failed with the following error: Operation timed out. 2009-05-19 19:19:07,837 ERROR - VM "snqfpapp01" will not be backed up since vmware snapshot create operation failed. I have a case open with Netapp but I'd like to see if the community has seen this. So has anyone else seen this problem?

cifs share umask for a unix qtree
by Roy McMorran 20 May '09

20 May '09

I have a qtree that's shared among NFS and CIFS clients. The security style is Unix. If I set the umask to be 002, ie: filer> cifs shares -change myshare -umask 2 Then the files created in the share via CIFS still have the *execute bits set*: $ ls -al test.txt -rwxrwxr-x 1 user group 4 May 19 16:41 test.txt That's not what I want; none of these files should really be executable. I have read at least one thread in the list archives that suggest using a umask of 113, ie: filer> cifs shares -change myshare -umask 113 This seems sketchy, but I gave it a try. Well, it works for files, but also omits the execute bits from newly-created *directories*: $ ls -ald test* -rwxrwxr-x 1 user group 4 May 19 16:41 test.txt -rw-rw-r-- 1 user group 4 May 19 16:43 test2.txt drw-rw-r-- 2 user group 4096 May 19 16:48 test And directories don't work so well in that case! Am I missing something? Why should it not behave like the Unix umask command (with respect to directories)? OnTap 7.2.5 if it matters.

Re: Any luck with SnapMirror & ESX LUN's ?
by Raj Patel 18 May '09

18 May '09

I guess one key factor is that VIBE is free(ish) and unsupported(?) from what I've read but SMVI is a supported product at a commercial price-point. Anyone tried the VMWare Site Recovery Manager tool ? Is there a NetApp integration component in the works (my understanding is the product leverages SAN vendor API's to ensure consistant intersite replication of VM's) ?

vmware userland file-level restores (vmdks on nfs + smvi)
by Nick Silkey 14 May '09

14 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Toasters -- Our bare-metal systems[1] are able to self-service themselves with TSM clients to perform file-level restores. There is a push to standardize on VMWare to replace the kit behind a lot of the low-hanging fruit Windows/Linux x86 systems. But theres a desire to not reduce function regarding file-level restores with the introduction of this new VMWare platform. We dont want to stick TSM clients on these guests due to redundant backup data shuffling over to pricy FC 3Par disk and the inordinate I/O load on the guests impacting ESX. We want to find a crafty means to leverage crash-consistent snaps on the NetApp (ala, SMVI) which is hosting all the vmdks in order to source restores, but no one is able to order the steps and pieces in such a way that allows people to self-service file-level restores. Theres been talk of craziness of exporting/serving snaps of vmdks to staging guests which can then browse the vmdk to pluck out files and other such hoop-jumping ... but this far from an elegant, scalable solution. The NetApp hosting VMWare serves VMDKs via NFS (3160 under 7.2.6.1). A-SIS and SMVI are components in this architecture as well. If anyone has crossed this path before, insight is appreciated. Thanks.

Any luck with SnapMirror & ESX LUN's ?
by Raj Patel 14 May '09

14 May '09

Hi, Anyone used SnapMirror successfully with ESX LUN's ? I realise it will only be a crash-consistent copy and I have to enable LUN re-signaturing for ESX to pick it up but this seems like a handy way for me to backup a few DMZ VM's on a LUN (on a seperate secured iSCSI vlan) to another LUN on the same SAN. Cheers, Raj.

snapmirror retrieve - multiple sites from one tape
by John Stoffel 07 May '09

07 May '09

Hi, We're starting to use snapmirror to help us migrate some data from old to new filers at sites. We're also going to use it to setup from snapmirror relationships across the WAN as well. What we'd like to do is make one tape on the source side, then ship that one tape to each of the destination sites, do the snapmirror store <vol> <drive> - ship to <dest> dest> snapmirror retrieve <vol> <drive> dest> snapmirror update -S <src>:<vol> <dest>:<vol> - ship to <another> another> snapmirror retriev <vol> <drive> another> snapmirror update -S <src>:<vol> <another>:<vol> Is this possible? It's not clear from the docs if you can do this. Hmm, looking at the Data Protection Using Snapmirror documentation, it looks like the base snapshot created by the 'store' command sticks around, and could be used for other snap mirror relationships, since it has to be manually deleted down the line. Any clarification would be appreciated.

NetApp3140 v EMC CX4-240
by Paul McGuinness 06 May '09

06 May '09

I am after opinions / Pros and Cons on running a substantial VMware infrastructure of approximate 200+ VMs using the 2 mentioned storage systems. Obvious benefits of the NetApp seem to be around the De-Dupe out of the box. Any other thoughts / experiences would be appreciated Fibre attached Dell R900s will be running the ESX side of things.
