Thanks, will fix that. Yes, the syntax got changed, looks like this was not reflected everywhere. > > Another one spotted right now : "6.5.

Did I miss something ? Is it planned ? You used a LVM pool, so yes, you get a full sync. Use a LVM-thinpool and the full sync gets skipped. > Also, in my test, when creating multiple resources simultaneously, I ended up > with a disconnect resource at creation (probably because network hasn't been > reacheable in time due to interface saturation) : > > vm-101-disk-5 ┊ dedie82 ┊ 7010 ┊ Unknown > > vm-101-disk-5 role:Secondary > disk:UpToDate > dedie82 connection:Connecting > > > Is there already some kind of disconnect/reconnect command with linstore ? (I > didn't manage to found it). No, if something needs fixing on the lower level, you then use lower level commands (drbdadm/drbdsetup). But this should not happen in the first place. You could try to restart the linstor-satellite service and check if it recovers.
