Bug 73449 – baselayout(?): Doesn't unmount md raid root partition on reboot/halt

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Prakash Punnoor 2004-12-05 07:41:55 UTC]

I am using current ~ baselayout and have following problem: On reboot/halt when remounting readonly appears, I get the message "md1 still being used" or alike. I recently switched / from "normal" reiserfs partition to a RAID0 ext3 partition, so I don't know whether it is a regression. Before that everything was fine, but now I am getting this message. I noticed sometimes on boot the journal on ext3 gets replayed, so that it really doesn't seem to get unmounted properly.

If this isn't baselayout trouble, what else could it be?

mount gives:

/dev/md1 on / type ext3 (rw,noatime)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev type tmpfs (rw)
none on /dev/pts type devpts (rw)
none on /dev/shm type tmpfs (rw)
none on /tmp type tmpfs (rw)
/dev/hda2 on /mnt/c type ntfs (ro,nosuid,nodev,umask=0222)
/dev/hda8 on /mnt/d type ntfs (ro,nosuid,nodev,umask=0222)
none on /proc/bus/usb type usbfs (rw)
nfsd on /proc/fs/nfs type nfsd (rw)
/dev/md0 on /usr/portage type xfs (rw,noatime)

/dev/md0 is mounted by hand, ie via loacal.start and umounted via local.stop, as I noticed that baselayout gets dependencies wrong, when raid partition are mixed with unraided. (This should be another bug report, but I am too lazy...: I once hat / normal, /usr raid and /usr/portage normal, so / and /usr/portage gets mounted first and then /usr, which is not desired....)

you neglected to provide `emerge info` like the bug report page says to

did this work in earlier versions ?

[Comment 4 Prakash Punnoor 2004-12-05 14:33:06 UTC]

As I already said, I haven't had a RAID array earlier, so I don't know whether it is a regression (ie if an earlier version worked).

[Comment 5 SpanKY 2004-12-05 14:47:39 UTC]

try this ...
emerge -f =baselayout-1.11.6-r1
tar -jxf /usr/portage/distfiles/rc-scripts-1.6.6.tar.bz2 rc-scripts-1.6.6/init.d/halt.sh
mv rc-scripts-1.6.6/init.d/halt.sh /etc/init.d/halt.sh
reboot

if you experience the same problem, then this is not a regression ;)

[Comment 6 Prakash Punnoor 2004-12-05 15:12:48 UTC]

No it doesn't help, but I found something interesting:

In local.start I change the default level of kernel logging via

echo 6 4 1 7 > /proc/sys/kernel/printk

Only with this commandI actually get this warning about my raid partition printed. Nevertheless, I never got troubles before putting my root on raid...

[Comment 7 SpanKY 2005-03-01 20:51:37 UTC]

could you try baselayout-1.11.9-r1 ?  we added a few extra retries in the final unmount/remount readonly code path ...

[Comment 8 Prakash Punnoor 2005-03-02 00:10:49 UTC]

I haven't noticed any issues lately, so I guess you can close it for now.

[Comment 9 SpanKY 2005-03-02 06:51:55 UTC]

ok, well please re-open if it starts acting up again :)
