Are you *sure* you mounted them as ocfs? Does the "mount -v" command confirm the filesystem type as ocfs? If it is ocfs, then I'm guessing maybe your devices aren't lined up right. That is, /dev/hdb1 on serverA is not the same as /dev/hdb1 on serverB. Therefore, it looks like you've mounted /dev/hdb1 as ocfs on each node, but they reference different hardware.

Two ORACLE RAC servers with shared disk in it. I create partition on shared disk and make it as OCFS file system. After that I mount partion on both servers. I can see OCFS file system on both servers. The wield thing are: 1. I use "vi" create "file1" on first server. 2. I use "vi" create "file2" on second server. 3. on first server. I can only see "file1" in there. same for secons server (it only see "file2"). I supposely should be see both files on either servers since they are shared file system. Does any one know why? ____________________________________________________________________________________ Need a vacation? Get great deals to amazing places on Yahoo!
