[Ocfs-users] RE: problem with OCFS label

[Raj]

Wu,

Before you do this make a BACKUP and save the Powerpath config files!!! 
IIMPORTANT!

If you are using EMC PowerPath 4.3.2 you can try to copy the following files 
across nodes in /etc/

-rw-r--r-- 1 root root 16384 Sep 1 18:59 /etc/emcp_devicesDB.dat
-rw-r--r-- 1 root root 4096 Sep 1 18:59 /etc/emcp_devicesDB.idx

Hope that helps.

Raj
