7.0R && amd does not unmount USB-based UFS

[Matthias Apitz]

Hello,

I'm using the amd to mount CDFS and MSDOSFS on USB without any kind of
problems for years; now I formated a new USB key with UFS, added the
config in amd's map and encounter that it does not unmount the file
system after the configured time of 20 secs:

any idea? thanks in advance;

details:

# cat /etc/amdmaps/amd.ufs
ufs           type:=ufs;fs:=/mnt/ufs;dev:=/dev/da0s1a;opts:=rw


# tail -f /var/log/amd

Oct 30 12:06:04 rebelion amd[23328]/info:  /etc/amdmaps/amd.ufs mounted fstype toplvl on /f

entering the dir /f/ufs mounts the FS:

Oct 30 12:08:02 rebelion amd[23328]/map:   Trying mount of /dev/da0s1a on /f/usf fstype ufs
Oct 30 12:08:02 rebelion amd[23328]/info:  /dev/da0s1a mounted fstype ufs on /mnt/ufs

here another example of entering /a/cdrom which gets unmounted after 20
secs:

Oct 30 12:54:49 rebelion amd[23328]/map:   Trying mount of /dev/acd0 on /a/cdrom fstype cdfs
Oct 30 12:54:50 rebelion amd[23328]/error: /cdrom: mount: Input/output error
Oct 30 12:54:50 rebelion amd[23328]/error: mount_cdfs: Input/output error
Oct 30 12:54:59 rebelion amd[23328]/map:   Trying mount of /dev/acd0 on /a/cdrom fstype cdfs
Oct 30 12:55:00 rebelion amd[23328]/info:  /dev/acd0 mounted fstype cdfs on /cdrom
Oct 30 12:55:20 rebelion amd[23328]/info:  /dev/acd0 unmounted fstype cdfs from /cdrom


the UFS stays mounted forever:

$ mount
/dev/ad4s1a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/ad4s1e on /tmp (ufs, local, soft-updates)
/dev/ad4s1f on /usr (ufs, local, soft-updates)
/dev/ad4s1d on /var (ufs, local, soft-updates)
pid23328 at rebelion:/u on /u (nfs)
pid23328 at rebelion:/a on /a (nfs)
pid23328 at rebelion:/f on /f (nfs)
/dev/da0s1a on /mnt/ufs (ufs, local)


a umount by hand helps:

# umount /mnt/ufs
# mount
/dev/ad4s1a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/ad4s1e on /tmp (ufs, local, soft-updates)
/dev/ad4s1f on /usr (ufs, local, soft-updates)
/dev/ad4s1d on /var (ufs, local, soft-updates)
pid23328 at rebelion:/u on /u (nfs)
pid23328 at rebelion:/a on /a (nfs)
pid23328 at rebelion:/f on /f (nfs)
