Hello,
When I try to create a raid1 volume over iscsi, process
aborts with :
- on target side:
iscsi_trgt: cmnd_abort(1156) 29 1 0 42 57344 0 0
iscsi_trgt: Abort Task (01) issued on tid:1 lun:0 by
sid:630024457682948
(Unknown Task)
Next run:
iscsi_trgt: cmnd_abort(1156) 13 1 0 42 57344 0 0
iscsi_trgt: Abort Task (01) issued on tid:1 lun:0 by
sid:630058817421315
(Unknown Task)
You can see that both lines are very similar. I shall
try to use
blockio instead fileio.
With blockio, I got the following message...
iscsi_trgt: cmnd_abort(1156) c 1 0 42 8192 0 0
iscsi_trgt: Abort Task (01) issued on tid:1 lun:0 by
sid:630024457682946
(Unknown Task)
Command is the same. What is the signification of 1156 ?
Both outputs are from the same Abort Task management function
the 1156 refers to the line in iscsi.c where the debug printf
was issued.
The other is the more verbose informative message that says
an Abort Task command was issued, but the task was not found.
pure guess, this might because the sparc64 you are using.
could you export a NULLIO target and do some intensive io tests? sort
out these platform issues first...
I can format serveral times (mkfs.ext3) a 1.5 TB volume over iSCSI
without any trouble. I can read and write on this virtual disk without
any trouble.
Now, I have configured ietd with :
Lun 0 Sectors=1464725758,Type=nullio
and I run on initiator side :
Root gershwin:[/dev] > dd if=/dev/zero of=/dev/sdj bs=8192
479482+0 records in
479482+0 records out
3927916544 bytes (3.9 GB) copied, 153.222 seconds, 25.6 MB/s
Root gershwin:[/dev] > dd if=/dev/zero of=/dev/sdj bs=8192
I'm waitinfor a crash. No one when I write these lines. I suspect an
interaction between raid and iscsi.

JKB
