Trying to add a LUN to a host and use that, instead of Gluster, as the datastore for my VM's.
by TomK 06 Oct '19

Hey All, I've added a 4TB LUN to my physical storage and now I want to use that, instead of GlusterFS as my datastore for VM's on that physical. How do I do this? I've tried a number of options, including adding LUN's but appears I can only add them to VM's directly but not use them as my datastores instead of GlusterFS. -- Thx, TK.

Please help me. Best Regards

oVirt 4.3.5 glusterfs 6.3 performance tunning
by adrianquintero＠gmail.com 04 Oct '19

Hello, I have a hyperconverged setup using ovirt 4.3.5 and the "optimize for ovirt store" seems to fail on gluster volumes. I am seeing poor performance and trying to see how should I tune gluster to give better performance.

Re: Recover node from partial upgrade
by Strahil 04 Oct '19

You can boot from the older image (grub menu) and then a cleanup procedure should be performed. I'm not sure if the thin LVs will be removed when you rerun the upgrade process , or they will remain the same.

Hello!!! I upgraded oVirtNode 4.3.5.2 to 4.3.6 using Engine UI. In the middle of the upgrade Engine fenced it, I can't understand why. Now Engine UI, and yum, report that there are no updates but node still to version 4.3.5.2. If I run "yum reinstall ovirt-node-ng-image-update" The result is as follow, but the system remain not upgraded. ovirt-node-ng-image-update-4.3.6-1.el7.noarch.rpm | 719 MB 00:06:31 Running transaction check Running transaction test Transaction test succeeded Running transaction Installazione : ovirt-node-ng-image-update-4.3.6-1.el7.noarch 1/1 warning: %post(ovirt-node-ng-image-update-4.3.6-1.el7.noarch) scriptlet failed, exit status 1 Non-fatal POSTIN scriptlet failure in rpm package ovirt-node-ng-image-update-4.3.6-1.el7.noarch Uploading Package Profile Cannot upload package profile.

Trust Red Hat :) At least their approach should be safer. Of course, you can raise a docu bug but RHEL7 is in such phase that it might not be fixed unless this is found in v8.

Red Hat says if metadat volume is full don't run a lvconvert --repair operation. Now I am confused. I am familiar with LVM and comfortable with it but this is my first time trying to repair thin LVM. The concepts of a metadata volume are new to me. > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)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/FFN3HWUQVRPFS…

mount to removed storage domain on node with HostedEngine
by Mark Steele 03 Oct '19

03 Oct '19

Hello, oVirt Engine Version: 3.5.0.1-1.el6 We recently removed the Data (Master) storage domain from our ovirt cluster and replaced it with another. All is working great. When looking at the old storage device I noticed that one of our nodes still has an NFS connection to it. Looking at the results for 'mount' I see two mounts to the node in question (192.168.64.15): 192.168.64.15:/nfs-share/ovirt-store/hosted-engine on /rhev/data-center/mnt/192.168.64.15:_nfs-share_ovirt-store_hosted-engine type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.15,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.64.15) 192.168.64.11:/export/testovirt on /rhev/data-center/mnt/192.168.64.11:_export_testovirt type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.11,mountvers=3,mountport=46034,mountproto=udp,local_lock=none,addr=192.168.64.11) 192.168.64.163:/export/storage on /rhev/data-center/mnt/192.168.64.163:_export_storage type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.163,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=192.168.64.163) 192.168.64.55:/export/storage on /rhev/data-center/mnt/192.168.64.55:_export_storage type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.55,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=192.168.64.55) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,relatime) 192.168.64.15:/nfs-share/ovirt-store/hosted-engine on /rhev/data-center/mnt/192.168.64.15:_nfs-share_ovirt-store_hosted-engine type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.15,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.64.15) 10.1.90.64:/ifs/telvue/infrastructure/iso on /rhev/data-center/mnt/10.1.90.64:_ifs_telvue_infrastructure_iso type nfs (rw,relatime,vers=3,rsize=131072,wsize=524288,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=10.1.90.64,mountvers=3,mountport=300,mountproto=udp,local_lock=none,addr=10.1.90.64) 192.168.64.163:/export/storage/iso-store on /rhev/data-center/mnt/192.168.64.163:_export_storage_iso-store type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.163,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=192.168.64.163) /etc/fstab has no entry for these so I assume they are left over from when the storage domain existed. Is it safe to 'umount' these mounts or is there a hook I may not be aware of? Is there another way of removing this from the node via that OVM? None of the other nodes in the cluster have this mount. This node is not the SPM. Thank you for your time and consideration.
