Hello,<div><br></div><div>getting DRBD to work with MySQL was not problem. However prior to adding heartbeat I want to get a fix on the 2 problems below: <br><div><br></div><div><div>Debian Lenny/LVM</div><div>DRBD 8.0.14 </div>
<div><br></div><div><br></div></div><div><div>(1) State change error: Trying to set active node to passive and vice-versa </div><div><br></div><div># drbdadm secondary mainvol</div><div>/dev/drbd0: State change failed: (-12) Device is held open by someone</div>
<div>Command 'drbdsetup /dev/drbd0 secondary' terminated with exit code 11</div><div><br></div><div># drbdadm down all</div><div>/dev/drbd0: State change failed: (-12) Device is held open by someone</div><div>Command 'drbdsetup /dev/drbd0 down' terminated with exit code 11</div>
<div>drbdsetup exited with code 11</div><div><br></div><div><div>picked up from a forum:</div><div># vgchange -an</div><div> Can't deactivate volume group "vg0" with 7 open logical volume(s)</div><div><br></div>
<div>I could literally tear the connection by severing the link between the nodes and then set the active node, but there must be a smoother way. </div><div><br></div><div><br></div><div>(2) After reboot the DRBD volumes on the primary are offline/not-mounted/locked by DRBD. Setting them primary resolves it and allows a mount -a to mount them all. Is this the default behavior without heartbeat ??</div>
<div><br></div><div>thanks - ies</div><div><br></div></div><div><br></div></div></div>
