Description Chris Denice 2012-01-17 11:46:48 CET

Hi there,
if you have a  "/usr" partition and uses sysvinit to boot then you end up with a system having /usr mounted read-only.

Looking to the logs, it looks like dracut mount anc check first the partitions "/" and "/usr" partitions. Then, sysvinit try to check them, but fails because they are already mounted by dracut. I don't know why "/" ends up being mounted rw wheares /usr remains ro.

The mounting goes fine if I use systemd; so it looks like an interaction pb in between dracut and sysvinit.
My fstab looks like this:


# Entry for /dev/sda1 :
UUID=5243cfa3-260f-4ebc-ae89-e4f1a4713f5d / ext4 acl,relatime 1 1
# Entry for /dev/sda7 :
UUID=06a67d1a-8d4d-4127-b775-a648873d57ec /usr ext4 acl,relatime 1 2

Cheers,
chris.

Are you using dracut or mkinitrd?

dracut, it logs some message at boot claiming to check/mount / and /usr.

Comment 3 Colin Guthrie 2012-01-18 11:36:47 CET

Yeah dracut mounts it readonly... I'm not sure if it's dracuts job to mount it rw initially, or systemd's job to remount it rw.... will ask upstream.

Comment 5 Chris Denice 2012-02-12 23:56:26 CET

Still there for the time being, but as Colin say, comes from dracut. So, it is also there with both systemd-sysvinit and sysvinit.

Cheers,
Chris.

I know this is actually fixed in latest dracut upstream, so it will be fixed when I get round to updating it (should be this week now I'm back from hols)

Comment 7 Chris Denice 2012-02-13 11:24:20 CET

Cool, thanks!

Comment 8 Chris Denice 2012-02-17 10:00:29 CET

Just to say that that works now, thanks guys, as far as I am concerned you can close the bug.

Cheers.

Comment 9 Colin Guthrie 2012-02-17 10:06:30 CET
