[dm-devel] Problem with Multipath (devices not ready)



Hi,

 

 

 

I have upgraded from SLES9-SP2 to SLES9-SP3.

The purpose was to fix some problems related to OCFS2.

 

I have many warnings (as you can see below) in my /var/log/messages related to multipath (i think), indicating that the devices aren't ready.

Maybe the multipath.conf needs some extra configuration (please see my multipath.conf).

The sdc and sdd devices are disks out on the EMC.

 

 

Can anyone help me with this problem ?
