Hi, i try to set up a 3 node gluster based ovirt cluster, following this guide: https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-glus... oVirt nodes were installed with all disks available in the system, installer limited to use only /dev/sda (both sda and sdb are HPE logical volumes on a p410 raid controller) Glusterfs deployment fails in the last step before engine setup: PLAY RECAP ********************************************************************* hv1.iw : ok=1 changed=1 unreachable=0 failed=0 hv2.iw : ok=1 changed=1 unreachable=0 failed=0 hv3.iw : ok=1 changed=1 unreachable=0 failed=0 PLAY [gluster_servers] ********************************************************* TASK [Clean up filesystem signature] ******************************************* skipping: [hv1.iw] => (item=/dev/sdb) skipping: [hv2.iw] => (item=/dev/sdb) skipping: [hv3.iw] => (item=/dev/sdb) TASK [Create Physical Volume] ************************************************** failed: [hv3.iw] (item=/dev/sdb) => {"failed": true, "failed_when_result": true, "item": "/dev/sdb", "msg": " Device /dev/sdb not found (or ignored by filtering).\n", "rc": 5} failed: [hv1.iw] (item=/dev/sdb) => {"failed": true, "failed_when_result": true, "item": "/dev/sdb", "msg": " Device /dev/sdb not found (or ignored by filtering).\n", "rc": 5} failed: [hv2.iw] (item=/dev/sdb) => {"failed": true, "failed_when_result": true, "item": "/dev/sdb", "msg": " Device /dev/sdb not found (or ignored by filtering).\n", "rc": 5} But: /dev/sdb exists on all hosts [root@hv1 ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 136,7G 0 disk ... sdb 8:16 0 558,9G 0 disk └─3600508b1001c350a2c1748b0a0ff3860 253:5 0 558,9G 0 mpath What can i do to make this work? ___________________________________________________________ Oliver Dietzel
