Hello, I'm relocating some disks from some storage domains to other ones. At the end I'm going to remove source storage domains. All the SD involved are FC and the hosts are CentOS 7.4 I see that after removing an SD from oVirt, the multipath part on host remains. What is the correct sequence of operations to do at hosts' side after completing the Webadmin Gui part? https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/storage_administration_guide/removing_devices (which seems to be similar to your steps below. I'd remove it from the storage side after flushing though). Y. Some questions: - do the remove SD from gui imply vgchange -an of the VG and vgremove of the vg? Or are they delegated to post actions? - do it imply the pvremove on the LUN? After clearing what above I would imagine remaining steps would be, based on my previous similar experience with iSCSI removal on physical servers: - take note of the paths sdY, ... of mpathX - remove the multipath device with multipath -f mpathX - flush the single paths devices blockdev --flushbufs sdY for every path of the previous taken note ones - remove single path devices echo 1 > /sys/block/sdY/device/delete - remove LUN from storage array when previous steps done on all the hypervisors Any comment? Any further step at vdsm level files..? Thanks in advance, Gianluca _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
