[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

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!
Regards,
Tibor
