xenserver problem VM disappeared

Does the disk for the disappeared vm show up in the xenserver datastore?
Check the SR, click on Storage tab.
If you see the disk there you an probably just recreate the vm from New VM wizard

dariosplit

No, not see the disk.

Restore from backup, if you've deleted the disk from the storage array your only choice is to recover.

DustinB3403

On a side note, why are you using a backup script when you can use XOCE (Xen Orchestra Community Edition).

dariosplit

I didn't delete it, it was working fine untill 9 AM untill 3:30 PM then it just disappeared and ofcourse there was no backup during that time

@dustinb3403 Vmbackup worked through cron perfectly

Have you performed a SR scan yet? If you can take a look and see if the disks are listed through XC, after you've scanned.

You might still find the disks and they might be orphaned.

It's not about cron or the script itself. XO (and XOCE as a branch to it) are about a better management platform with logging and everything in a single pane of glass management interface.

You might not have deleted the VM, it doesn't mean a cleanup job didn't or another admin by mistake.

DustinB3403

Or your recovery job might have come in after the restore and deleted the original VM. I know some scripts have that functionality.

Looks like this is what he's using? https://github.com/NAUbackup/VmBackup

DO NOT RUN THIS SCRIPT UNLESS YOU ARE COMFORTABLE WITH THESE ACTIONS.

    For vm-export: (a) xe vm-snapshot, (b) xe template-param-set, (c) xe vm-export, (d) xe vm-uninstall on the vm-snapshot.
    For vdi-export: (a) xe vdi-snapshot, (b) xe vdi-param-set, (c) xe vdi-export, (d) xe vdi-destroy on the vdi-snapshot.

No idea what this actually means, but I'm guessing the backup script deleted your base disk (the snapshot?) for the recovered VM?

Can't +1 this enough, it truly is great.

DustinB3403

@bnrstnr NAUBackup, yeah I used that and immediately got rid of it when I found XO.

It's a solid script but dangerous if you screw up.

DustinB3403

IIRC it does delete the original VM once the restore is completed.

I used it for about a month and it was why I was looking for alternatives and found XO so many years ago now.

Sorry to be the bearer of bad news, hopefully you'll find that XO is a much better approach to managing XenServer.

When it comes to MSSQL, it would've been best to use its own builtin backup instead.

That is true, but it only backups the database.

Backing up the VM you need something that is SQL aware. Which bring up the question, is XO SQL aware. . .

Hrm. . . that is a question worth asking.

Any database, really.

I don't think so. I almost never try to use an image based backup for data.
