[DRBD-user] State change failed: Device is held open by someone

[Ben Clewett]

Dear drbd,

I hope this is a simple one, and sorry for all the email today!

I am trying to set drbd to Seconday.  When I try I get this:

kernel: drbd0: State change failed: Device is held open by someone
kernel: drbd0:   state = { cs:Connected st:Primary/Secondary 
ds:UpToDate/UpToDate r--- }
kernel: drbd0:  wanted = { cs:Connected st:Secondary/Secondary 
ds:UpToDate/UpToDate r--- }

All 'ps' or 'lsof | grep drbd' options I can think of do not give me any 
clue as to who this is.  I can't shut down drbd for the same reason.

This keeps happening due to problems with linux-ha mounting the file 
system and failing.  Manually mounting the file system works perfectly.

Does any kind member have an idea as to how I can clear this?

Kind regards,

Ben
