<span style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt">Hi there <br />
<pre>> But when you're trying to write to the mounted drbd disk then you got:
> [ 59.754706] JBD2: I/O error detected when updating journal superblock for drbd0-8.
> [ 59.754948] Aborting journal on device drbd0-8.
> [ 59.755004] JBD2: I/O error detected when updating journal superblock for drbd0-8.
> [ 68.648409] EXT4-fs error (device drbd0): ext4_journal_start_sb: Detected aborted journal
> [ 68.648601] EXT4-fs (drbd0): Remounting filesystem read-only
</pre>
I'm facing the same problem here. I unmounted the disk and created an ext3 file-system. I have the same errors in the logfiles and am not able to write. <br />
This error ocured with drbd-8.3.11rc2<br />
<br />
As an alternative, it is possible to use drbd-8.3.9 without any problem. (Version drbd-8.3.10 doesnt work with RHEL 6.1 because of the bug you described:<br />
<pre>/usr/src/drbd/drbd-8.3.11rc1/drbd/drbd_receiver.c:1860: error:
'REQ_UNPLUG' undeclared (first use in this function)</pre>
