Interesting. As I got another Debian box working with iSCSI 2.0.873+git0.3b4b4500-8+deb8u1 and debian kernel 4.3.0 on the same target/debain MD3200i with no errors yet. Also ext4.

Hm, currently not, it was our main storage server, I do not want to set it offline again, but if I see the same error on another box, I´ll do my very best. > Also, is there anything in the MD320 logs about a command being rejected > because it is not supported? Not really, mostly this: Date/Time: 08.03.16 13:19:38 Sequence number: 17388 Event type: 180C Event category: Internal Priority: Informational Event needs attention: false Event send alert: false Event visibility: true Description: iSCSI connection terminated unexpectedly Event specific codes: 0/0/0 Component type: iSCSI Initiator Component location: iqn.1993-08.org.debian:01:84455b760a Logged by: RAID Controller Module in slot 0 There is a update available from Dell for that storage, not yet applied due to "load on storage cannot be stopped yet". Maybe it could help.
