[Bug 267279] [NEW] DRBD Primary-Primary Setup on Hardy crashes in certain situations

[Henri Cook]

Public bug reported:

Binary package hint: drbd8-utils

This may be kernel related I suppose, if DRBD is present there.

Assume the following setup:

Node A running a DRBD drive (OCFS2) with local (/dev/md5) metadata and mounted at /shared
Node B running a DRBD drive (OCFS2) with local (/dev/md5) metadata and mounted at /shared

A runs an FTP server

Client X starts transferring a file into the FTP server on A which is
writing to /shared i.e. /shared is mounted AND in use

If Node B (which is doing nothing really) gets rebooted by typing
'reboot', Node A upon detecting the DRBD network failure also reboots -
this is a hard reboot (no logs, or shutdown actions run).

This makes ubuntu-server unuseable for a primary-primary raid1-over-
network setup with DRBD and the version of DRBD should be drastically
upgraded for Intrepid (or backported to hardy considering the
seriousness) assuming it's been fixed in one of the releases up to 8.2

This does not affect Primary/Secondary DRBD setups as far as I can tell
