Sahina, Can someone from your team review the steps done by Adrian? Thanks, Freddy On Thu, Apr 25, 2019 at 5:14 PM Adrian Quintero <adrianquintero@gmail.com> wrote:
Ok, I will remove the extra 3 hosts, rebuild them from scratch and re-attach them to clear any possible issues and try out the suggestions provided.
thank you!

I have the same locks , despite I have blacklisted all local disks:
# VDSM PRIVATE blacklist { devnode "*" wwid Crucial_CT256MX100SSD1_14390D52DCF5 wwid WDC_WD5000AZRX-00A8LB0_WD-WCC1U0056126 wwid WDC_WD5003ABYX-01WERA0_WD-WMAYP2335378 wwid nvme.1cc1-324a31313230303131353936-414441544120535838323030504e50-00000001 }
If you have multipath reconfigured, do not forget to rebuild the initramfs (dracut -f). It's a linux issue , and not oVirt one.
In your case you had something like this: /dev/VG/LV /dev/disk/by-id/pvuuid /dev/mapper/multipath-uuid /dev/sdb
Linux will not allow you to work with /dev/sdb , when multipath is locking the block device.

under Compute, hosts, select the host that has the locks on /dev/sdb, /dev/sdc, etc.., select storage devices and in here is where you see a small column with a bunch of lock images showing for each row.
However as a work around, on the newly added hosts (3 total), I had to manually modify /etc/multipath.conf and add the following at the end as this is what I noticed from the original 3 node setup.
------------------------------------------------------------- # VDSM REVISION 1.3 # VDSM PRIVATE # BEGIN Added by gluster_hci role
blacklist { devnode "*" } # END Added by gluster_hci role ---------------------------------------------------------- After this I restarted multipath and the lock went away and was able to configure the new bricks thru the UI, however my concern is what will happen if I reboot the server will the disks be read the same way by the OS?
Also now able to expand the gluster with a new replicate 3 volume if needed using http://host4.mydomain.com:9090.
thanks again

Strahil, this is the issue I am seeing now
[image: image.png]
The is thru the UI when I try to create a new brick.
So my concern is if I modify the filters on the OS what impact will that have after server reboots?
thanks,

I have edited my multipath.conf to exclude local disks , but you need to set '#VDSM private' as per the comments in the header of the file. Otherwise, use the /dev/mapper/multipath-device notation - as you would do with any linux.

Thanks Alex, that makes more sense now while trying to follow the
instructions provided I see that all my disks /dev/sdb, /dev/sdc, /dev/sdd are locked and inidicating " multpath_member" hence not letting me create new bricks. And on the logs I see
Device /dev/sdb excluded by a filter.\n", "item": {"pvname":
"/dev/sdb", "vgname": "gluster_vg_sdb"}, "msg": "Creating physical volume '/dev/sdb' failed", "rc": 5}
Same thing for sdc, sdd
Should I manually edit the filters inside the OS, what will be the impact?
thanks again. _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/FW3IR3NMQTYZLX...
