[dm-devel] Maps not created for read-only devices



Using SuSE10 with multipath-tools-0.4.6-25.8 and device-mapper-1.02.03-8.2, I am having the following problem.  When I set a LUN to read-only on the storage controller, the LUN does not show up under "multipath -l".

The following debug messages show up from multipathd for the read-only device:

Jan 23 11:56:35 | mpath6: set ACT_CREATE (map does not exist)
Jan 23 11:56:35 | mpath6: domap (0) failure for create/reload map

Meanwhile I see the following entries in /var/log/messages:

Jan 24 08:58:36 suse10 kernel: device-mapper: dm-multipath: error getting device
Jan 24 08:58:36 suse10 kernel: device-mapper: error adding target to table

If the LUN is set to read/write access I have no problems.

Does anyone have any ideas why this might be happening?

Thanks,
Mike
