Hi
I cannot start my VM. Error appeared as attached. Seems like my datastore is not activate. How to activate the datastore?

It is missing from all of the outputs. Is "sdb" the underlying device for datastore3? If it is - it seems to be missing LVM signatures.
Check "fdisk -l /dev/sdb", as well as "journalctl |egrep "datastore3|sdb" " for any errors in activation.

You lost your data back in February:
Code: 
Feb 20 12:14:29 BCScloud lvm[565]:   3 logical volume(s) in volume group "datastore3" monitored
Feb 20 12:14:29 BCScloud lvm[831]:   pvscan[831] PV /dev/sdb online, VG datastore3 is complete.
Feb 20 12:14:29 BCScloud lvm[831]:   pvscan[831] VG datastore3 skip autoactivation.

Feb 20 12:27:28 BCScloud lvm[4972]:   pvscan[4972] /dev/sdb not an lvm device.

You can try to figure out what happened in those 12 minutes by examining the journal.
Lookup articles on the net for LVM recovery and give them a try if the data is important.

good luck.
