Hi guys,

I just compiled DRBD from source and everything went alright and I got the module and other binaries and all.

I loaded the module like I did before and with the same drbd.config file I got:

Starting DRBD resources:    [ d(drbd1) s(drbd1) n(drbd1) ].Failure: (114) Lower device is already claimed. This usually means it is mounted.

[drbd1] cmd /sbin/drbdsetup /dev/drbd1 disk /dev/RBcYOG02/r1 /dev/RBcYOG02/r1 internal --set-defaults --create-device --on-io-error=call-local-io-error  failed - continuing!

Funny thing is, the lower device is not mounted and is formatted and is ready to go but it keeps complaining about it.

I created another partition (/dev/sda7) and after stopping the module, I used it this time, but "/etc/init.d/drbd start" got stock on:
Starting DRBD resources:    [ d(drbd1)

I terminated it (Ctrl + C) and "/etc/init.d/drbd start" now gives me:
Starting DRBD resources:    [ d(drbd1) Failure: (124) Device is attached to a disk (use detach first)

[drbd1] cmd /sbin/drbdsetup /dev/drbd1 disk /dev/sda7 /dev/sda7 internal --set-defaults --create-device --on-io-error=call-local-io-error  failed - continuing!

And /proc/drbd shows:
version: 8.2.5 (api:88/proto:86-88)
GIT-hash: 9faf052fdae5ef0c61b4d03890e2d2eab550610c build by alirezan at winlx-1, 2008-10-29 21:38:36

 1: cs:Connected st:Unknown/Primary ds:Attaching/UpToDate C r---
    ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:1 pe:0 ua:0 ap:0

and worse thing is, I can't even stop drbd anymore!!!

root /home/alireza/drbd-8.2.5/drbd Revolution 1# service drbd stop
Stopping all DRBD resourcesERROR: Module drbd is in use

Any ideas why this is happening and how I can fix it?

Thanks guys
