** Description changed:
Binary package hint: heartbeat-common
Package heartbeat-common 2.99.2+sles11r9-5ubuntu1 in karmic contains a
critical bug:
The script
- /usr/lib/ocf/resource.d/heartbeat/Filesystem
+ /usr/lib/ocf/resource.d/heartbeat/Filesystem
contains a list of filesystem types for which fsck is not run. This list
does not include ext4, although it does include ext3.
+
+ =======
+ SRU Justification
+
+ IMPACT:
+
+ This bug affects users running DRBD clusters with ext4 filesystem on
+ top. Every time that a cluster node tries to perform a takeover on a
+ DRBD resource with ext4 filesystem, it will run fsck, which can cause
+ the takeover to take much longer than expected. In Clustered scenarios,
+ this might affect the availability. For this reason, some filesystems
+ avoid this step, including ext3. Unfortunately, ext4 is not yet listed
+ in the version for Maverick.
+
+ REPRODUCE:
+
+ 1. Install a two node DRBD cluster with Pacemaker. Format the DRBD block
device with ext4.
+ 2. Once they are configured and running in Master/Slave, perform a hard
takeover by switching off the Master node.
+ 3. In the Slave node, check syslog, where the following output will appear:
+
+ lrmd: [2623]: info: RA output: (res_fs:start:stdout) fsck from util-
+ linux-ng 2.17.2
+
+ HOW FIXED:
+
+ The fix is simple, and consists on adding ext4|ext4dev to the list of
+ filesystems for which to avoid performing fsck.
+
+ PATCH:
+
+ Attached. Uploaded to maverick-proposed for review there.
+
+ REGRESSION POTENTIAL:
+
+ Minimal. I've tested this thoroughly.
