<p class="MsoNormal">Hi everyone,<br>
<br>
I am trying to do a failover system only with drbd. When my primary node get out of the network, the secondary node became primary and I mount the filesystem.<br>
secondary# drbdadm primary r7<br>
secondary# mount /dev/drbd7 /mnt/drbd7/<br>
<br>
Until that every thing is ok.<br>
At this time, my old primary node has to became the secondary and I have to discard my changes.<br>
primary# umount -l /mnt/drbd7<br>
primary# drbdadm secondary r7<br>
7: State change failed: (-12) Device is held open by someone<br>
Command 'drbdsetup 7 secondary' terminated with exit code 11<br>
primary# drbdadm -- --discard-my-data connect r7<br>
<br>
Does anyone have a hint?<br>
Thnaks in advance!<br>
Felipe<br clear="all">
