Description Daniel Riek 2008-11-07 11:46:57 EST
From IT 237323:

Description of problem:

Qdisk now is started via cman init script. Starting qdiskd always fail with the following message in /var/log/messages:

   Oct 29 20:02:14 esblade1 qdiskd[6146]: <crit> Specified device /dev/mpath/sas1p1 does match kernel's reported sector size (0 != -1)

The output of mkqdisk -L has looked quite normal, den multipath-device was listed in the first lines, even if as always the two qdisk devices are shown with parameters (Creation date and so on) are the both underlying sd-devices.

Also reformatting the qdiskd device didn't work, also with zero-ing it before and recreating it using mkqdisk.

cluster.conf configuration was done in this way:

  <quorumd device="/dev/mpath/sas1p1" interval="5" log_facility="local4" log_level="4" status_file="/tmp/quorum_state" tko="4" votes="2">
    <heuristic interval="3" program="ping -c1 -t3" score="1"/>

How reproducible:

Setup a RHEL5.3 BETA cluster. Start cman and have a look at the line when qdiskd starts. Also have a look on /var/log/messages.

Steps to Reproduce:

See above.

Actual results:

Qdiskd won't start and won't work.

Expected results:

Qdiskd should start and work.

Additional info:

Changing the binary to the one from RHEL5.2 seems to work, but in RHEL5.2 qdiskd only seems to work (does not cman_tool leave or reboot if actual scores fall below min_scores, even if paranoid=1 is defined).

This happens only when 'device' is used.  On 5.3 beta, 'device' is no longer required in multipath configurations because we added intelligent scanning which avoids multipath slaves.

Correct the logic around block size checking.
Comment 6 Lon Hohberger 2008-11-07 13:31:48 EST
Oh - and remove status_file before going to production. :)
