[Bug 583508] [NEW] EXT3-fs error (device dm-0)

[braincloud]

Public bug reported:

While trying to run a python program, the program kept terminating and
saying "read-only file system"

dmesg initially said something about resetting the hardware interface...

I rebooted, and the problem seemed to go away, but then it came back
again, and started throwing the errors below:

Computer Info: Linux XXXXXX 2.6.28-18-generic #60-Ubuntu SMP Fri Mar 12 04:26:47 UTC 2010 x86_64 GNU/Linux
Ubuntu 2.6.28-18.60-generic
This computer has a huge RAID drive (4.1TB), but I can't provide more information because someone else set it up.

Output of dmesg:
