Christoph,
apologies for the delay I was on a long leave.
Also is there a chance you could allow setting
only SCRATCH_DEV_POOL for btrfs, and derive SCRATCH_DEV for that as an
additional step?
There is some challenge to set SCRATCH_DEV based on FSTYP since
SCRATCH_DEV is used even before FSTYP is set.
common.config uses SCRATCH_DEV and we set FSTYP in common.
check calls these two script files in the following logic.
--------------------------
# we need common.config
if ! . ./common.config
then
echo "$iam: failed to source common.config"
exit 1
fi
# we need common
. ./common
---------------------------
to avoid major changes what we could do is to find-out FSTYP on our
own in the file common.config and set SCRATCH_DEV based on
SCRATCH_DEV_POOL, but thats a bit ugly way. I am open to any
suggestions. thanks.
Please use the sysfs interface instead of the deprecated /proc/scsi/scsi
interface. I would also suggest to split this routine into two for
removing and adding, and move them to the common helper library, so it
could be used for other tests.
yes. will get something like below code. in the common
-----
remove:
echo 1 >
/sys/class/scsi_device/${host}:${channel}:${id}:${lun}/device/delete
add:
echo "$channel $id $lun" > /sys/class/scsi_host/host${host}/scan
-----
+# we need this to test removing a dev from the system
+_require_proc_scsi()
+{
+ [ -e /proc/scsi/scsi ] || _notrun "/proc/scsi/scsi is not present"
+}
The _require need really is that the device you want to work on is a
SCSI device.
will get this.
Thanks -Anand
