Hello all, I did all steps as I described in previous email, but no change. I can't see any LUN after discovery and login of new iSCSI storage. (That storage is ok, if I try to connect it to another and older ovirt domain, it is working...) I tryed it on 3 new iSCSI targets alredy, all have same problem... Can somebody help me, please? -- Lukas Kaplan 2017-03-27 16:22 GMT+02:00 Lukáš Kaplan <lkaplan@dragon.cz>:
I did following steps:
- delete target on all initiators (ovirt nodes) iscsiadm -m node -T iqn.2017-03.cz.dragon.ovirt.fuvs-sn1:10T -p 10.53.1.201:3260 -u iscsiadm -m node -T iqn.2017-03.cz.dragon.ovirt.fuvs-sn1:10T -p 10.53.1.201:3260 -o delete
- stop tgtd on target - fill storage by zeroes (dd if=/dev/zero of=/dev/md125 bs=4096 status=progress) - start tgtd - tried to connect to ovirt (Discovery=ok, Login=ok, but can not see any LUN).
=== After that I ran this commands on one node: ===
[root@fudi-cn1 ~]# iscsiadm -m session -o show tcp: [1] 10.53.0.10:3260,1 iqn.2017-03.cz.dragon.ovirt:ovirtengine (non-flash) tcp: [11] 10.53.0.201:3260,1 iqn.2017-03.cz.dragon.ovirt.fudi-sn1:10T (non-flash) tcp: [12] 10.53.1.201:3260,1 iqn.2017-03.cz.dragon.ovirt.fuvs-sn1:10T (non-flash)

Hello all,
please do you have some experience with troubleshooting adding of iSCSI domain to ovirt 4.1.1?
I am chalenging this issue now:
1) I have successfuly installed oVirt 4.1.1 environment with self-hosted engine, 3 nodes and 3 storages (iSCSI Master domain, iSCSI for hosted engine and NFS ISO domain). Everything is working now.
2) But, when I want to add new iSCSI domain, I can discover it, I can login, but I cant see any LUN on that storage. (I had same problem in oVirt 4.1.0, so I made upgrade to 4.1.1)
Are you sure mappings are correct? Can you ensure the LUN is empty? Y.
3) Then I tryed to add this storage to another oVirt environment (oVirt 3.6) and there are no problem. I can see LUN on that storage and I can connect it to oVirt.
I tryed to examine vdsm.log, but it is very detailed and unredable for me :-/
Thak you in advance, have a nice day, -- Lukas Kaplan
