Check the status of the multipath demon: multipathd status I have seen a problem where the demon would die after starting. I believe there is an update to multipath tools to fix this (at lease for Suse there is). You should be mounting by label rather that /dev/dm-x. Label the drives and then use: LABEL=mylabel in the fstab file. The relationship between dm-x and any particular is not persistent between boots. In other words, dm-2 may be the oragrid volume next time. I have seen another problem. After mounting by label the 'mount' command shows the drives mounting as /dev/sdx rather than a multipathed device. You may have to delay the multipath demon at boot time for things to settle. Adding a 'sleep 5' to the appropriate startup script will usually fix it. good luck, cs ________________________________

We are on OEL version 2.6.18-92.el5 and we are using multipathing. Here are the OCFS2 entries in /etc/fstab. /dev/dm-2 /oracw oracle_clusterware datavolume,nointr,_netdev 0 0 /dev/dm-3 /oragrid oracle_home datavolume,nointr,_netdev 0 0 Should we be using the "mapper" device names in the /etc/fstab file?
