Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


Seems this is a common problem!!! Can you point those of us experiencing " Device is held open by someone " to a DRBD resource (documentation) that gives an overview in this area for a better understanding of what may be going on? I will look at www.drbd.org for info.


Thanks,

Dan Phillips

It's always worth checking device-mapper:

dmsetup ls --tree -o inverted
