Hi there,
We hit a iscsid die case. use ps -ef|grep iscsid, we only saw one iscsid
process.
Unfortunately, we didn't enable debug log so there are not many logs
available. We looked at the iscsid log it states that it received some
kernel reported error. Also, in the kernel log, there is OOP complaints.
After that, we used open-iscsi init script to restart, but the kernel
modules were not been able to removed. We issue iscsiadm -m session, it
gives:
r...@swe_1_ser_2:~# iscsiadm --mode session
tcp: [17] []:-1,1 \ufffd\ufffd?\ufffd|0\ufffdHYw
The iscsiadm --mode session -P 3 hangs:
r...@swe_1_ser_2:~# iscsiadm --mode session -P 3
iSCSI Transport Class version 2.0-870
iscsiadm version 2.0-870
Target: \ufffd\ufffd?\u04cbA\ufffd\ufffd\ufffd?
Current Portal: []:-1,1
