Hello,
I'm running my Ovirt-Node-NG based Hosts off ISCSI root. That is what "vdsm-tool config-lvm-filter" suggests. Is this correct ?
[root@myhostname ~]# vdsm-tool config-lvm-filter Analyzing host... Found these mounted logical volumes on this host:
logical volume: /dev/mapper/onn_myhostname--iscsi-home mountpoint: /home devices: /dev/mapper/mpath-myhostname-disk1p2
logical volume: /dev/mapper/onn_myhostname--iscsi-ovirt--node--ng--4.2.7.1--0.20181209.0+1 mountpoint: / devices: /dev/mapper/mpath-myhostname-disk1p2
logical volume: /dev/mapper/onn_myhostname--iscsi-swap mountpoint: [SWAP] devices: /dev/mapper/mpath-myhostname-disk1p2
logical volume: /dev/mapper/onn_myhostname--iscsi-tmp mountpoint: /tmp devices: /dev/mapper/mpath-myhostname-disk1p2
logical volume: /dev/mapper/onn_myhostname--iscsi-var mountpoint: /var devices: /dev/mapper/mpath-myhostname-disk1p2
logical volume: /dev/mapper/onn_myhostname--iscsi-var_crash mountpoint: /var/crash devices: /dev/mapper/mpath-myhostname-disk1p2
logical volume: /dev/mapper/onn_myhostname--iscsi-var_log mountpoint: /var/log devices: /dev/mapper/mpath-myhostname-disk1p2
logical volume: /dev/mapper/onn_myhostname--iscsi-var_log_audit mountpoint: /var/log/audit devices: /dev/mapper/mpath-myhostname-disk1p2
This is the recommended LVM filter for this host:
filter = [ "a|^/dev/mapper/mpath-myhostname-disk1p2$|", "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.
Configure LVM filter? [yes,NO]
Yoval, is /dev/mapper/mpath-myhostname-disk1p2 expected on node system? Ralf, can you share the output of: lsblk multipath -ll multipathd show paths format "%d %P" Nir

Hello Greg,
this is what i was looking for.
After running "vdsm-tool config-lvm-filter" on all hosts (and rebooting them) all PVs, VGs and LVs from ISCSI domain were not visible anymore to local LVM on the ovirt hosts.
Additionally i made following tests: - Cloning + running a VM on the ISCSI domain - Detaching + (re-)attaching of the ISCSI domain - Detaching, removing + (re-)import of the ISCSI domain - Creating new ISCSI domain (well, i needed to use "force operation" because creating on same ISCSI target)
All tests were successful.
As you wished i filed a bug: <https://github.com/oVirt/ovirt-site/issues/1857> <https://github.com/oVirt/ovirt-site/issues/1857> Thank you.
