Public bug reported:
open-iscsi can't shut down (and I think this machines the whole machine can't)
because umountiscsi.sh doesn't
like the current layout of /sys:
# /etc/init.d/umountiscsi.sh
* Unmounting iscsi-backed filesystems
umount: /: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
* Could not unmount /
umount: /: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
* Could not unmount /
At this point I have iscsi devices enabled/logged in - but not mounted,
so it shouldn't be unmounting any.
The problem seems to be the following code in umountiscsi.sh
for HOST_DIR in /sys/devices/platform/host*; do
if ! [ -d $HOST_DIR/iscsi_host* ]; then
continue
fi
for SESSION_DIR in $HOST_DIR/session*; do
if ! [ -d $SESSION_DIR/target* ]; then
continue
fi
for BLOCK_FILE in $SESSION_DIR/target*/*\:*/block/*; do
BLOCK_DEV=`echo "$BLOCK_FILE" | sed 's/.*block\///'`
DOS_PARTITIONS="`awk "/^\/dev\/$BLOCK_DEV/ { print
\\$2; }" < /proc/mounts`"
for DEVICE in $DOS_PARTITIONS; do
So:
# ls /sys/devices/platform/host*
/sys/devices/platform/host2:
iscsi_host power scsi_host session1 subsystem uevent
/sys/devices/platform/host3:
iscsi_host power scsi_host session2 subsystem uevent
ok, so we have those, but if we have a look under the target directory
that the for BLOCK_FILE is looking in there is no block directory:
# ls /sys/devices/platform/host2/session1/target2\:0\:0/*:*
bsg device_blocked generic iodone_cnt iorequest_cnt model
queue_depth queue_type rev scsi_generic state timeout
uevent
delete evt_media_change iocounterbits ioerr_cnt modalias power
queue_ramp_up_period rescan scsi_device scsi_level subsystem type
vendor
so that isn't being glob'd and we end up with
BLOCK_FILE=/sys/devices/platform/host2/session1/target*/*:*/block/*
and then it all goes horribly wrong and tries to umount /
So I'm guessing that something changed in the kernel iscsi/scsi code
that changed the layout of that.
