open-iscsi logout errors
I am using open-iscsi-2.0-869.2 and even since the 2.0-868.x releases, I am facing this error when logging out. Out of the four targets (all go to one box), only one session successfully logs out. Other three fail. The 3 are sessions are still open. Even killing iscsid process manually doesnt help. The following is a continuous output: * [EMAIL PROTECTED]:~$ sudo /etc/init.d/open-iscsi stop * Disconnecting iSCSI targetsLogging out of session [sid: 2, target: iqn.1984-05.com.sample:example.0061c23000ce22f047626207, portal: 192.168.202.99,3260] Logging out of session [sid: 3, target: iqn.1984-05.com.sample:example.0061c23000ce22f047626207, portal: 192.168.202.101,3260] Logging out of session [sid: 4, target: iqn.1984-05.com.sample:example.0061c23000ce22f047626207, portal: 192.168.202.100,3260] Logging out of session [sid: 5, target: iqn.1984-05.com.sample:example.0061c23000ce22f047626207, portal: 192.168.202.98,3260] Logout of [sid: 2, target: iqn.1984-05.com.sample:example.0061c23000ce22f047626207, portal: 192.168.202.99,3260]: successful iscsiadm: got read error (0/2), daemon died? iscsiadm: Could not logout of [sid: 3, target: iqn.1984-05.com.sample:example.0061c23000ce22f047626207, portal: 192.168.202.101,3260]: iscsiadm: initiator reported error (18 - could not communicate to iscsid) iscsiadm: got read error (0/2), daemon died? iscsiadm: Could not logout of [sid: 4, target: iqn.1984-05.com.sample:example.0061c23000ce22f047626207, portal: 192.168.202.100,3260]: iscsiadm: initiator reported error (18 - could not communicate to iscsid) iscsiadm: got read error (0/2), daemon died? iscsiadm: Could not logout of [sid: 5, target: iqn.1984-05.com.sample:example.0061c23000ce22f047626207, portal: 192.168.202.98,3260]: iscsiadm: initiator reported error (18 - could not communicate to iscsid) [ OK ] * Stopping iSCSI initiator service [ OK ] [EMAIL PROTECTED]:~$ sudo /etc/init.d/open-iscsi status Current active iSCSI sessions: tcp: [3] 192.168.202.101:3260,2 iqn.1984-05.com.sample:example.0061c23000ce22f047626207 tcp: [4] 192.168.202.100:3260,2 iqn.1984-05.com.sample:example.0061c23000ce22f047626207 tcp: [5] 192.168.202.98:3260,1 iqn.1984-05.com.sample:example.0061c23000ce22f047626207 [EMAIL PROTECTED]:~$ [EMAIL PROTECTED]:~$ sudo iscsiadm -m session tcp: [3] 192.168.202.101:3260,2 iqn.1984-05.com.sample:example.0061c23000ce22f047626207 tcp: [4] 192.168.202.100:3260,2 iqn.1984-05.com.sample:example.0061c23000ce22f047626207 tcp: [5] 192.168.202.98:3260,1 iqn.1984-05.com.sample:example.0061c23000ce22f047626207 [EMAIL PROTECTED]:~$ * However, there is no data loss.

Hi, Konrad! Thanks for you advice! > Are you mounting that filesystem across many nodes (ie, through my > iscsi-initators)? > Yes, that's exactly what I had done.

You would need to use GFS or GFS2 to do this. GFS2 or GFS seems have some problem in Genoo across to bugzilla. So you just think GFS/GFS2 is good enough ? Or is there any other recommended clustered-aware filesystem? -- wcw --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.

Input/output error and strange problem ?
Hi, I use open-iscsi-2.0.869.2 and iscsitarget-0.4.15-r1, and in my test, some strange errors occur. In all my iscsi-target, I have a ext3 fs. And I mount these fs in the iscsi-initator. 1, Input/output error Once I copied a file into iscsi-target, I got the error "Input/output error" after a "lseek" operation. And then I tried copying again, I succeed this time. I still found more similar problems in "open" operation. Why sometimes it failed and sometimes succeed? 2, latency problem Here is the log of the operation in the iscsi target: $ ls lost+found $cat hello hello $ls lost+found As you can see, when I did "ls", I didn't see the file "hello", but the strange thing is that I could do "cat hello" and I got the correct result. Why I can't "ls" but can "cat"? Any help will be appreciated! -- wcw --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
