Drive auto mounting as read only (errors=remount-ro)












1














My system is auto-mounting as read only and I have no idea why.



Output of fstab:



cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

none on /run/shm type tmpfs (rw,nosuid,nodev)


I have searched all night including:
Ubuntu 12.04 SSD root frequent random read only file system



I have no idea why this is going on. I did run fsck at boot and it didn't find errors.



The disk is fine (500GB, user 38GB)

          When you say you ran the fsck at boot and didn't find any errors, do you know that from watching it run or from the log files in /var/log/fsck? If it's from those log files, know that they haven't worked in years (see bug 513644).



          How do you know your drive has no errors? Did you run the manufacturer tool from a boot CD such as UBCD?



          I would boot to a LiveUSB/LiveCD and check the filesystem manually:



          sudo fsck /dev/sda1
