Re: Going readonly too frequently



Clearly you have a corrupt filesystem. Of all these times that the filesystem has gone read-only, how many times have you done FSCKs?  Have you done two FSCKs in a row?  It's rare, but  I've seen a second FSCK find stuff that was missed on the first run.

A smart report will at least tell you if the drive has been suffering errors recently.

Do you have a SMART report for the drive?
