OCFS2 is often used in high-availability systems. However, OCFS2 usually

converts the filesystem to read-only when encounters an error. This may not be

necessary, since turning the filesystem read-only would affect other running

processes as well, decreasing availability.

Then, a mount option (errors=continue) is introduced, which would return the

-EIO errno to the calling process and terminate furhter processing so that the

filesystem is not corrupted further. The filesystem is not converted to

read-only, and the problematic file's inode number is reported in the kernel

log. The user can try to check/fix this file via online filecheck feature.

On receiving the inode, the filesystem would read the inode and the

file metadata. In case of errors, the filesystem would fix the errors

and report the problems it fixed in the kernel log. As a precautionary measure,

the inode must first be checked for errors before performing a final fix.
