Pvcreate fails on drbd devices
|
|
Hello,
I'm using DRBD 8.3.2 on RHEL 5.2 (x86_64). I've sucessfully create
two DRBD devices, /dev/drbd1 and /dev/drbd2 (drbd.conf below). I'm
trying to use them as physical volumes for LVM, as described in the
"Configuring a DRBD resource as a Physical Volume" section of the
user guide. But pvcreate fails:
pssrv101:103% sudo pvcreate -ff /dev/drbd1
Device /dev/drbd1 not found (or ignored by filtering).
pssrv101:104% sudo pvcreate -ff /dev/drbd2
Device /dev/drbd2 not found (or ignored by filtering).
pssrv101:106% sudo pvcreate -ff /dev/drbd/by-res/r1
Device /dev/drbd/by-res/r1 not found (or ignored by filtering).
pssrv101:107% sudo pvcreate -ff /dev/drbd/by-res/r2
Device /dev/drbd/by-res/r2 not found (or ignored by filtering).
The DRBD volumes are certainly present:
pssrv101:112% ls /dev/drbd*
/dev/drbd1 /dev/drbd2
/dev/drbd:
by-disk/ by-res/
pssrv101:115% cat /proc/drbd
