I was testing zfs over iscsi (with commstar over a zvol) and got some errors.
Target and initiator are on the same host.
I''ve copy-pasted an excerpt on zpool status hereafter.
The pool (tank) containing the iscsi-shared zvol (tank/tsmvol) is healthy and
show no errors.
But the zpool (tsmvol) on the initiator side shows errors.
The processes that where running to generate some IO load/volume are stuck and
aren''t killable.
Zpool destroy tsmvol, zpool export tsmvol, zfs list stay stuck.
I managed to open an ssh session by connecting as an user that has no homedir
and thus doesn''t run quota (which is stuck and non killable too).
My questions are the following?:
1 - why does the tsmvol pool show up as degraded when the only device it
contains is itself degraded ?
Shouldn''t it show as faulted ?
2 - why are my load generating processes (plain old cat) unkillable ?
Shouldn''t they have been killed by ioerrors caused by the dead pool ?
I guess this is what the failmode setting is for, so I''ll set it for
the rest of my tests.
But I''m a bit puzzled about implications.
3 - how could there be errors in localhost transmission ?
I followed the basic steps outlined in commstar''s how to, are there
some specific settings to set for localhost iscsi access ?
Thanks for your help,

OK, the third question (localhost transmission failure) should have been posted
to storage-discuss.
I''ll subscribe to this list and ask there.
Regarding the first question, after having removed the lun from the target,
devfsadm -C removes the device and then the pool shows as unavailable. I guess
that''s the proper behaviour.
Still the processes are hung and I can''t destroy the pool.
This leads to being unable to open a new session with a user that has a home
dir.
I copy-pasted some mdb results I found while looking for a way to get rid of the
pool.
Please note I had failmode=wait for the failling pool.
But since you can''t change it once you''re stuck,
you''re bound to reboot in case of iscsi failure.
Or am I misunderstanding something ?

Objet?: Zfs over iscsi bad status
I was testing zfs over iscsi (with commstar over a zvol) and got some errors.
Target and initiator are on the same host.
I''ve copy-pasted an excerpt on zpool status hereafter.
The pool (tank) containing the iscsi-shared zvol (tank/tsmvol) is healthy and
show no errors.
But the zpool (tsmvol) on the initiator side shows errors.
The processes that where running to generate some IO load/volume are stuck and
aren''t killable.
Zpool destroy tsmvol, zpool export tsmvol, zfs list stay stuck.
I managed to open an ssh session by connecting as an user that has no homedir
and thus doesn''t run quota (which is stuck and non killable too).
My questions are the following?:
1 - why does the tsmvol pool show up as degraded when the only device it
contains is itself degraded ?
Shouldn''t it show as faulted ?
2 - why are my load generating processes (plain old cat) unkillable ?
Shouldn''t they have been killed by ioerrors caused by the dead pool ?
I guess this is what the failmode setting is for, so I''ll set it for
the rest of my tests.
But I''m a bit puzzled about implications.
3 - how could there be errors in localhost transmission ?
I followed the basic steps outlined in commstar''s how to, are there
some specific settings to set for localhost iscsi access ?
Thanks for your help,
Arnaud
