Do it.  Sorry I didn't have time to check this list today until now.  I manage 
servers for a living.  Lots of them.  Mostly CentOS, but more than a few 
Debian and Ubuntu based as well.

The Linux kernel will always remount a file system read-only if it detects 
drive errors; simply to save the data you've got.

Look at post 4 of this thread (it doesn't matter that it's a fedora forum; the 
issue is kernel-specific, not OS-specific):

But if it's easy enough to rebuild, I'd do it.

What we do in this kind of case, is replace the drive (and rebuild RAID since 
we run RAID on our servers).  We always have spares.  And then we know we've 
got a good drive.

Then we take the supect drive to the workbench, wipe it, reformat it, and 
exhaustively test it for a few days.  If it passes, it goes back to the DC as 
a spare; if not, we wipe it again if possible, and then destroy it or send it 
to a recycleer, depending on how sure we are that we've removed all the data.
