rcdrbd status
Before proceeding, wait until the block devices on both nodes are fully synchro-
nized. Repeat the
rcdrbd status
command to follow the synchronization
progress.

device on the primary with a file system such as reiserfs. Any Linux file system
can be used. For example, enter
mkfs.reiserfs -f /dev/drbd0
IMPORTANT
Always use the
/dev/drbd<n>
name in the command, not the actual
/dev/disk
device name.
