I find this problem more info :
I use flashcache on ovirt hosts , have dm device in /dev/mapper/ :
[root@horeba init.d]# dmsetup info -C （and I set them in multipath
blacklist ）
Name Maj Min Stat Open Targ Event UUID
flash_sdb 253 0 L--w 0 1 0
flash_sdf 253 2 L--w 0 1 0
flash_sdd 253 1 L--w 0 1 0
[root@horeba init.d]# multipath -l
[root@horeba init.d]#
[root@horeba init.d]# ll /dev/mapper/
total 0
crw------- 1 root root 10, 236 Nov 25 10:09 control
lrwxrwxrwx 1 root root 7 Nov 25 12:51 flash_sdb -> ../dm-0
lrwxrwxrwx 1 root root 7 Nov 25 12:51 flash_sdd -> ../dm-1
lrwxrwxrwx 1 root root 7 Nov 25 12:51 flash_sdf -> ../dm-2
on this condition , ovirt UI add iscsi type storage will fail .
If I delete the flashcache device /dev/mapper/flash_* , ovirt UI add
iscsi type storage have no problem .
I need flashcache for using ssd cache on my environment , how can I use
iscsi type storage on this environment , please help me , Thanks！

A wild guess, not sure if it is related - can you check if multipathd service
is enabled. If you set up your oVirt-Gluster hyperconverged environment via
gdeploy, multipathd service is disabled and the /etc/multipath.conf is edited
to blacklist all devices - this was to fix
https://bugzilla.redhat.com/show_bug.cgi?id=1303940
Since you mention you're unable to add iscsi storage only in this environment,
thought it's worth checking.

Thanks for the logs,
What kind of VDSM version are you using?
"rpm -q vdsm"
There seems to be a similar issue which was reported recently in the VDSM area
(see https://bugzilla.redhat.com/show_bug.cgi?id=1197292)
It should be fixed in later versions of VDSM vdsm-4.16.12-2.el7ev.x86_64
Adding also Nir and Jeff to the thread, if they have any insights
Regards,
Maor

Hi 胡茂荣
Can u please also add the VDSM and engine logs.
If you try discover and connect to those luns directly from your Host does it
work?

Maor
