Read Only File System?

Read Only File System?

[Marc Perkel]

Not sure where to ask this question so I'll try here. I have a Raid 0 
EXT3 file system that is coming up read only. I don't think it's raid 
related but not sure why it's stuck on read only.

When I run mount it shows:
/dev/md0 on /data type ext3 (rw,noatime)

But when I attempt (running as root) to change anything I get:
touch: cannot touch `x': Read-only file system

When I list the directory I get this:
drwxr-xr-x    8 root root  4096 Sep 29 15:15 .
drwxr-xr-x   45 root root  4096 Oct  4 10:42 ..
drwxr-xr-x    4 root root  4096 Sep 11 03:17 critical
drwx------    2 root root 16384 Sep 10 22:37 lost+found
drwxr-xr-x   19 root root  4096 Sep 11 02:07 mirror
dr-x------   14 root root  4096 Sep  9 09:52 Robin
drwxr-xr-x    7 root root  4096 Oct  5 02:16 snapshot
drwxrwxr-x+ 289 root root 12288 Oct  1 03:20 www

Note the weird permissions on Robin. This happened because I was trying 
to save data from a crashed Windows NT system and I used rsync to copy 
the data over. And I noticed the problem around the same time.

So - what can I do to fix this?

Does your dmesg have some info on this?

1. check dmesg
2. run a recent version of e2fsprogs (aka e2fsck)
