xapi seems to broken after a Power Failure
-
olivierlambert I'm pretty sure these server are upgraded from older XenServer.
And since it only shows up one drive in BIOS It should be partition -
LunarstarPony If I remember correctly I think it's update from XenServer 5.6 to XCP-ng 7.0 and then XCP-ng 8.2.
-
olivierlambert I haven't reinstall yet but when I'm wondering around I do see that there's a backup for the 7.0 XCP-ng. Is it possible to get the database from there?
-
Yes but the database will be outdated and will work only for the version it was installed on (eg XenServer 7.0).
BTW, there's no such thing as XCP-ng 7.0
-
olivierlambert What will happened if I restore the backup? And update it again?
-
LunarstarPony Oh and maybe it's 7.5 xD
-
If you restore the backup, you'll have your XAPI DB as it was before you made the upgrade
-
olivierlambert Hugh Alright Sounds like I should able to just restore the backup and upgrade it again then?
-
olivierlambert If that's the case I'd give it a go later
-
That's a possibility, yes. If you think the DB state back in there is still relevant and you didn't create a lot of VM since your upgrade.
-
olivierlambert It does fixed the system issue even tho now there's quite a few of Orphan VDIs on the System but at least the server's back. Thx a lot!
-
Great!
Next time, don't forget to get metadata backup for the pool. At least, your XAPI DB will be saved!
-
olivierlambert I now have both server in a Pool now and I'll also remember to backup them as well
-
olivierlambert How can I backup Metadata directly? Seems like I'll need at least Enterprise if I want to backup it via XOA
-
LunarstarPony Either via Command line or SFTP or XCP-ng Center?
-
In XO: New backup/Metadata/Pool Metadata, select the backup repository, and that's it
What XOA Edition do you have?
-
olivierlambert Oh I got it working! Thanks a lot!
-
olivierlambert Oh BTW Since now I got a remote storage using NFS and I notice we got a thick provisioned disk(lvm), if I migrate the disk from that server to our new NFS Remote Storage, will that make the Virtual Disk thin and release the extra spaces? or it will remain as a Thick provisioned disk?
-
LunarstarPony If it will still remain as a thick provisioned disk is there a way to change it to thin and reclaim space?
-
Yes it will be instantly thin on destination.
