Open Stack

Sorry,nova-volume was not stop clearly, when I uncomment --nexenta_target_prefix, create a volume is fine,but still could not attach it to instance, compute node log is just :

ISCSI volume not yet found at: vdc. Will rescan & retry.  Try number: 0

And in dashboard,it was failing into "attaching" status.

Yuriy,

Thanks for your reply.

I try to uncomment --nexenta_target_prefix="iqn.1986-03.com.sun:01:005008c802ff.4fb2f97d" and then restart nova-volume, but the result is still error as same as before,volume service log has no error,but compute node brief log is:

Attaching volume 1 to /dev/vdc
ISCSI volume not yet found at: vdc. Will rescan & retry.  Try number: 0
Attach failed /dev/vdc, removing
....
Command: sudo iscsiadm -m node -T "iqn.1986-03.com.sun:01:005008c802ff.4fb2f97d"volume-00000001 -p 192.168.1.42:3260 --rescan
Exit Code: 255
Stdout: ' '
Stderr: 'iscsiadm: No portal found.\n'

But when I manually run " iscsiadm -m node -T "iqn.1986-03.com.sun:01:005008c802ff.4fb2f97d"volume-00000001 -p 192.168.1.42:3260 --rescan", it is ok.

Regards,

Romi

Try to remove that quotes from nexenta_target_prefix flag. They seem
to be the source of this problem.

Kind regards, Yuriy.
