[Bug 1063354] Re: Sudden Read-Only Filesystems
[Problem probably solved]
I changed my fstab and removed the "defaults"-entry:
Probably this was the problem and the "defaults"-entry puts some mount options, that interfere with the ssd.
fatab-NEW: /dev/mapper/vg--myvg-root / ext4 noatime,errors=remount-ro 0 1
fstab-OLD: /dev/mapper/vg--myvg-root / ext4 defaults,noatime,errors=remount-ro 0 1
I left the libata option in modprobe and kernel boot options:
> cat /etc/modprobe.d/options
options libata noacpi=1
> cat /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash libata.force=noncq libata.noacpi=1"
Since two days the system is running without any filesystem-freezes.
I am attaching an ubuntu bug-report which can probably help to solve and analyse the problem.
The system is up to date as time of writing and all necessary updates are applied.
-------------------------------------------------------------------------------
I have to add, that I am running a newer version of lvm2 with gives me the option of using TRIM:
ii lvm2 2.02.95-4ubuntu1.1~p Linux Logical Volume Manager
All necessary entries in crytptab and lvm.conf are done and trim is working (on demand).

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.
