iscsiadm exit code 8

[gbr]

Hi,

I attached an iSCSI device (Ubuntu running iSCSI Enterprise Target), and added LVM on top of it.

I created a volume and formatted it ext4, in order to do a dd test (hammering writes on the drive to get speeds). The dd test failed with disk errors. I was unable to fsck the volume, so I removed the LVM drive and removes the iSCSI, then re-added them. I had to re-add the LVM with the same name.

Now, I get the following error:

Oct 25 09:07:24 proxmox pvestatd[2662]: WARNING: command '/usr/bin/iscsiadm --mode node --targetname iqn.2013-04.com.majentis:storage.disk.1 --login' failed: exit code 8

and the device is not available. Path/Target is empty in the web gui.

So, I have three questions:

1. is LVM over iSCSI stable in 3.1?
2. if I had real data on the iSCSI, would it be lost?
3. Is there a way I can get this up again?

Just for info, the iscsi did the following:

I have another iSCSI LUN on the same server, and it is still functional.
