[ovirt-users] Re: 4.2.8 to 4.3.7 > Management slow

You can manually change the I/O scheduler of the disks and if that works better for you, put a rule in udev. Here is mine: [root@engine rules.d]# cat /etc/udev/rules.d/90-default-io-scheduler.rules ACTION=="add|change", KERNEL=="sd*[!0-9]", ATTR{queue/scheduler}="none" ACTION=="add|change", KERNEL=="vd*[!0-9]", ATTR{queue/scheduler}="none" [root@engine rules.d]# cat /sys/block/vda/queue/scheduler [none] mq-deadline kyber Best Regards, Strahil Nikolov On Dec 31, 2019 12:30, Demeter Tibor <tdemeter(a)itsmart.hu&gt; wrote: Dear Users, I've successfully upgraded my 4 node hyperconverged system from 4.2.8 to 4.3.7. After upgrade everything seems to working fine, but the whole management system seems very slow. Spends many seconds when I clicking on "virtual machines" or I want to edit a virtual machines. The speed of vms and the IO is fine. It is running on a glusterfs (distributed replicate, on 3 node, 9 bricks). There are no errors, everything fine. but terrible slow:( The engine vm has 0.2-0.3 load. What can I do? Thanks in advance and I wish Happy New Year!
