hello
i'm adding a new host into ovirt
after the installation procces is finished I got an error: "VDSM kvm6
command ConnectStoragePoolVDS failed: Cannot find master domain".
on the vdsm server in /dev/disk/by-path/ i see the block device but
device-mapper not mappying it
then I found the master's lun in the blacklist:
/etc/multipath/conf.d/vdsm_blacklist.conf
why vdsm host put the lun wwn in blacklist and what I can do ?
addition info:
============
Ovirt-engine 4.4.7
vdsm server:

Better to check /dev/disk/by-id/. Could you check the ID of this device is the same as one
in the blacklist?
If so, could you please also share output of
/usr/bin/lsblk --raw --noheadings --paths --inverse --include 253 --nodeps --output
type,name,mountpoint
and also VG info of this device:
vgs --readonly --config 'devices {filter=["a|.*|"]}' $VG_NAME
so we can analyze it?
what I can do ?
remove it from blacklist

When adding a host, we run:
vdsm-tool config-lvm-filter
This command put the LUN in the blacklist since it seems to be a local
disk used by the host. Did you have active logical volumes from this LUN
mounted on the host while the host was added to engine?
After you fix the issue (see Vojta reply), please run again:
vdsm-tool config-lvm-filter
The command may suggest to change the lvm filter, and blacklist the device.
Do not confirm and share the output.

disk used by the host.
yes, but in fact this disk is a remote block device from fc storage
Did you have active logical volumes from this LUN mounted on the host
while the host was added to engine?
I installed only Centos, updated it and connected the Ovirt repository,
all another settings were made by Engine himself

removed line wwid "3600000e00d11000000113629000e0000" from vdsm_blacklist.conf
and ran vdsm-tool config-lvm-filter
here is the command output:
Analyzing host...
Found these mounted logical volumes on this host:
This is the recommended LVM filter for this host:
filter = [ "r|.*|" ]
This filter allows LVM to access the local devices used by the
hypervisor, but not shared storage owned by Vdsm. If you add a new
device to the volume group, you will need to edit the filter manually.
This is the current LVM filter:
filter = [ "r|.*|" ]
To use the recommended filter we need to add multipath
blacklist in /etc/multipath/conf.d/vdsm_blacklist.conf:
blacklist {
wwid "3600000e00d11000000113629000e0000"
wwid "3600605b010bbc0e029275d23bba8027b"
}
9:20 a.m.
Could you check the ID of this device is the same as one in the
blacklist?
yes it is same:

could you run it again, but instead of "--include 253" use number you get when
run
cat /proc/devices |grep device-mapper| cut -f 1 -d ' '
i.e.
INC=`cat /proc/devices |grep device-mapper| cut -f 1 -d ' '` &&

sorry, I was interested in LV tags, i.e. the command should be
lvs --readonly --config 'devices {filter=["a|.*|"]}' --options

yes, it won't be overwritten until you run "vdsm-tool config-lvm-filter" and
