I've a problem with quiesced file system snapshot on a VM that has RDM iscsi Lun connected through esx host instead of using iscsi.
The configuration is as follow:
esx 4 update 1 (with all patches excluded the ones released on last friday) using NFS for VM operating system disks
netapp 3160 with data ontap 7.3.2p4
1 VM with:
windows 2008 64bit (fully patched)
exchange 2007
snapdrive 6.2p1
snapmanager for exchange 6.0
I have 4 lun created with snapdrive and connected through esx instead of using microsoft iscsi on 1 volume.
I also have a lun with the descriptors for the RDM on another volume.
When I try to get a snapshot of the VM with the option to quiesce the file systems it get to 95% and then It will exit after 15 minutes with errors.
Doing an exchange backup with snapmanager works without any problem.
I tried disabling the VSS provider inside the vmware tools (they're also updated to the latest ones) and in that case the snapshot will work istantly but I think that without the VSS provider the snapshot will not be consistent.
Anyone is using a similar configuration with success leaving the vss provider on?
