Hi all,

sys: Centos 5.3, drbd 8.3.1 from Centos-Testing

Steps I did:

unmount filesystem then
# resize2fs -p /dev/drbd0 25G
# drbdadm -- --size=25G resize r0
# lvresize -l 801 -t -v /dev/mapper/VG00-LVsrv
(800 extends are 25GB, 1 for metadata)

All these commands came back w/o error, but drbd was detached:

drbd0: drbd_bm_resize called with capacity == 52428800
drbd0: resync bitmap: bits=6553600 words=102400
