OCFS--->Oracle cluster file system, it was not mounting. We have two node RAC.
RAC1.corp.com----> first node
RAC2.corp.com----> second node
Here in this configuration ocfs was used to store OCR and Voting disk. Since OCFS2 is a seperate mount point, it was not mounting because of some error.
when we typed df -h, all the mount points were shown except the /ocfs which was storing OCR & Voting Disk. Without these two files we cannot run the databases. very crucial for the RAC systems.
when we tried to mount the /ocfs manually,
# mount -t /ocfs2 -a
we found this error
Workaround:
first i checked the network connections between the nodes...
when i pinged the node2 it was not pinging and it is actually getting routed to vip of the local node. then found it because of the device name, changed it later the network was working fine, after that
stopped ocfs:
# ./o2cb stop ocfs2
then started ocfs:
# /etc/init.d/o2cb start
then mounted the ocfs::
mount -t ocfs2 -o datavolume,nointr /dev/sdb1 ocfs
it worked!!!
