Re: EXT3-fs unexpected failure msg ?

You really, really, really need to mount your filesystem with

I'm not sure if this is enough to prevent corruption in the case
of your RAID disconnects (if it doesn't generate errors up to the
filesystem, but still discards writes), but it is at least a minimum

Since this was so strongly-worded, I just did a random spot-check of some of our filesystems (RHEL4) and discovered they all have:

   Errors behavior:          Continue

in the superblock (and mount apparently takes that option). This makes me curious: if it's so obvious that it should remount-ro on errors, why is the default (on RHEL4, at least) to continue?
