[Ocfs2-users] Trouble getting node to re-join two node cluster (OCFS2/DRBD Primary/Primary)

[Sunil Mushran]

-F does not run the full fsck. -f does.

But I would not recommend running fsck as this corruption is not
normal. The inodes in the system directory have been overwritten.
That typically means a storage issue. The fs does not create/remove
inodes in sysdir. Only the tools do that.

You may want to shutdown drbd and access the devices directly on
the two machines. See if they are ok. If so, then select one as the
master and copy it to the other.
