[Bug 1063354] Re: Sudden Read-Only Filesystems
Just a follow up... My problem is fixed or at least figured out.
Although many with this bug have similar log output mine was definitely
hardware. SATA hard drives have extremely fragile connectors and the
connector to this particular drive with the read only problem was
slightly pushed down by another connector. It finally broke the HD plug
socket just enough to make a bad connection. It's practically
imperceptible until you remove the connector as see the slight movement
of the HD plug component. I reconnected the plug and put slight
pressure underneath the component, started the computer and it fired
right up. The system did a forced fsck and it is working with all data
present and permissions corrected. Now I just need to dump all the data
to a new HD.
This may be an issue for some and not for others but the outcome and the
dmesg logs show ata errors on that drive. It would be very easy to miss
the breakage since it's a very small variance, and it's bizaar that it
causes the read only problem as stated above but nothing else.

Title:
Sudden Read-Only Filesystems
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
After upgrading to ubuntu 12.10, I experience sudden locks of my
filesystems (I have a root and a home partition with ext4), in which
the filesystems suddenly become mounted readonly. /var/log/syslog
shows the following entries:

The harddrive is one month old and has no defects (AFAIK). The problem
arises anywhere between directly after boot and 3h into working. A
remount with mount -o remount,rw is not possible and aborted with an
error. Since I will most certainly loose data during work, this
renders my system unusable for the moment. The problem did not occur
when running 12.04.
