Re: [DRBD-user] Proxmox VE 4.2 and DRBD 9 other problem

[Jean-Daniel TISSOT]

After another reboot, some links disappears from /dev/drbd/by-disk/drbdpool and 
/dev/drbd/by-res.

For example i have 3 VM so /dev/drbd100, /dev/drbd101 and /dev/drbd102 
correspond to theses VM raw disks.
But in /dev/drbd/by-disk/drbdpool i have no more the link for vm-101-disk-1_00 
to /dev/drbd100
and no directory /dev/drbd/by-res/vm-101-disk-1 with a link in it named 0 to 
/dev/drbd100

Could anybody explain this ?
