Snapshot fails on Ubuntu

[alainrussell]

Hi,

I've setup VDR recently and have been having issues with one of the virtual servers (Ubuntu Server 9.04 64bit). It fails to backup with an error "Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine." We have 6 Ubuntu servers and this is the only one that seems to have an issue. All the others appear to be backing up fine (MySQL servers etc, this particular server is Apache)

I've tried to manually take a snapshot and get the same error. I found a KB article about renaming old snapshot attempt files and tried this, latest VM Tools are installed but nothing seems to work.

Any help appreciated.

Thanks

Alain

Try removing VMware Tools and test it. If you are able to backup then, try reinstalling the tools without the Sync driver (vmsync module). By some reason the quiesced snapshot are not able to freeze a consistent state of the VM. Maybe you can find a reason on the vmware tools logs or on dmesg, or /var/log/messages.

Thanks Marcelo,

I tried removing the tools and get a different error now - File

Not sure what this is - the datastore attached to the backup is an NFS share of 256GB, I'm only backing up 6 servers to it at the moment, all 10-20GB of storage.

Ho do you install the Linux server tools without vmsync ? Can't see an option for that in the command line.

Thanks
