We're using ZFSThin as backend for our Linstor cluster. Nothing fancy.
I'm trying to set up a backup with ZFS snapshots and zfs send/receive.
First : is this a bad idea ? I know DRBD integrate his own snapshot
system (LVM only ?) but it can't be exported to a non-DRBD system as-is
So, to automate the backup, I have to write a script that check which
ressources are primary on the host (and that the host is not a diskless
client) and get the ZFS backedn device for a resource.
So, main question : is there a linstor command to get the 'grepable'
backend device for a resource on a host ?
Without having to grep into a file the /var/lib/linstor.d ? (prone to
I tried some lisntor commands without success. Perhaps with a command
from drbd-utils ?
Thanks for your advice(s),
