data / os disks, snapshots

[mouk]

Hi,

Just wondering if there is a good solution for this:

One mailserver in proxmox, two disks, one with the OS, other disk containing data, mounted on /var/vmail for maildir data.

I create a snapshot and then start a big software update. The server runs for a few hours, but the updates turn out nasty, I I would like to revert to the snapshot.

My understanding is that in that scenario, I would loose the mails that have arrived during those hours: also the data disk would be reverted to the state of a few hours earlier.

Is there a way to revert only the OS disk, and KEEP the disk containing /var/vmail?

Not that I know of. I think you can seperate it only when you use lvmsnapshot inside the vm. But maybe someone is me disabuse.
