[linux-lvm] bug in lvm-1.0.7-105 ?




Hello,


I think I found a bug in the

/etc/init.d/boot.lvm

script. (SuSE 9.0)

The Script mounts the root filesystem read/write to write
the information from vgscan to /etc/lvmtab.d/.

After that it tries to remount the root filesystem again with:

mount -n -o remount,ro /

This fails, which lead to a error message when

/etc/init.d/boot.localfs

is run.

This is the fix for /etc/init.d/boot.lvm:

[...............]
else
echo "Remounting root file system (/) read/write for vgscan..."
mount -n -o remount,rw /
test $FSCK_RETURN -gt 0 && touch /fsck_corrected_errors
echo "Scanning for LVM volume groups..."
/sbin/vgscan


# NEW [START]
z=0
mount -n -o remount,ro /
while [ ! $? = 0 ] ; do
echo "ro mount failed: $z"
sleep 1
let "z=$z+1"
if [ $z -gt 10 ] ; then
break;
fi
mount -n -o remount,ro / done
# NEW [END]
[...............]



After usually 5 seconds the readonly mount succeeds. (Is this some internal buffer flush time in the kernel ?) The root filesystem is reiser.

regards,


Martin
