Hi All,
Just wondering of a few things:
1. Has anyone seen a problem like this before (see below)? This occurs
when mounting the file system. It mounts, but goes straight to
read-only mode.
2. I've scanned the device (/dev/sdd) using 'badblocks -s v', which
reports no bad blocks found.
3. What can be done to recover from this? (I'm planning to upgrade to
3.18 before trying recovery/repairs)
Thanks,
Dyweni
