recovery required on read-only filesystem

[wizard10000]

ext4 boot partition and I'm getting this on every boot - over about the past week or so. I'm reasonably certain the drive is good as it's on a six-month old netbook.

Jul 24 04:58:51 wizard-netbook kernel: [ 2.891225] EXT4-fs (sda1): INFO: recovery required on readonly filesystem
Jul 24 04:58:51 wizard-netbook kernel: [ 2.891366] EXT4-fs (sda1): write access will be enabled during recovery
Jul 24 04:58:51 wizard-netbook kernel: [ 6.380208] EXT4-fs (sda1): recovery complete
Jul 24 04:58:51 wizard-netbook kernel: [ 6.380696] EXT4-fs (sda1): mounted filesystem with ordered data mode

fstab shows

# / was on /dev/sda1 during installation
UUID=5b95e3e3-12a5-40fc-85c8-a00b80b96c97 / ext4 errors=remount-ro 0 1
# /home was on /dev/sda3 during installation
UUID=ace0cbda-881b-47e9-b8cb-b42d9d86bdf7 /home ext4 defaults 0 2
# swap was on /dev/sda2 during installation
UUID=efd86d82-9ad0-4973-a3ba-20fecd26e2ac none swap sw 0 0

so I think I see what's causing it, but does anybody have an idea here? fsck from a live CD shows no errors on the disk but then I can boot the machine and still get the error.

edit: More info.

fsck -NV from my lubuntu live USB shows no errors on the disk and after it's run the machine will boot without error *once*. Strange.

Re: recovery required on read-only filesystem

Sounds like /dev/sda1 is not being sync'd during shutdown. Maybe there is a bug and an error during the shutdown is causing init to abend before syncing the disks.

Try shutting down with sysrq rseiub and see if the error occurs on next boot.

Maybe you're onto something. Shutdown throws a message that says / is busy.

thanks!
