Can you try to set the credentials in a file (don't recall where that was for ceph) , so you can mount without specifying user/pass ?

impact of --emulate512 setting for VDO volumes
by Guillaume Pavese 02 Mar '19

02 Mar '19

Hello, We are planning to deploy VDO with oVirt 4.3 on centos 7.6 (on SSD devices). As oVirt does not support 4K devices yet, VDO volumes are created with the parameter "--emulate512 enabled" What are the implications of this setting? Does it impact performance? If so, is it IOPS or throughput that is impacted? What about reliability (is that mode equally tested as standard mode)? As I saw on RH Bugzilla, support for 4K devices in oVirt will need to wait at least for Centos 7.7 Once that is supported, would it be possible to transition/upgrade an emulate512 vdo volume to a standard one? Thanks, Guillaume Pavese Ingénieur Système et Réseau Interactiv-Group

Another option is to try nfs-ganesha - in my case I can reach 80MB/s sequential writes in the VM.

Before I used the optimize for vm storage it was about 10x less. Iirc the optimize setting it suppose to get set by the installler by default but it wasn’t set in my case when I used cockpit to deploy (this was a little while ago on ovirt 4.2).

Can you try setting the viodiskcache custom property to write back ? Best Regards, Strahil

Gluster messages after upgrade to 4.3.1
by Stefano Danzi 01 Mar '19

01 Mar '19

Hello, I've just upgrade to version 4.3.1 and I can see this message in gluster log of all my host (running oVirt Node): The message "E [MSGID: 101191] [event-epoll.c:671:event_dispatch_epoll_worker] 0-epoll: Failed to dispatch handler" repeated 59 times between [2019-03-01 10:21:42.099983] and [2019-03-01 10:23:38.340971 Another strange thing: A Vm was running. I shutted down it fo mistake. I was no more able to run this vm. The error was: "Bad volume specification ". After a little investigation I notice that disk image was no more owned by vdsm.kvm but root.root. I changed back to correct value and vm started fine.

[oVirt 4.3.1-RC2 Test Day] Hyperconverged HE Deployment

Hi, I tried again today to deploy HE on Gluster with oVirt 4.3.1 RC2 on a clean Nested environment (no precedent deploy attempts to clean before...). Gluster was deployed without problem from cockpit. I then snapshoted my vms before trying to deploy HE both from cockpit, then from cmdline.
