Dear All,
I have just noticed that my Hosted Engine has a strange I/O scheduler:
Last login: Sun Mar 17 18:14:26 2019 from 192.168.1.43
[root@engine ~]# cat /sys/block/vda/queue/scheduler
[mq-deadline] kyber none
[root@engine ~]#
Based on my experience anything than noop/none is useless and performance
degrading for a VM.
Is there any reason that we have this scheduler ?
It is quite pointless to process (and delay) the I/O in the VM and then
process (and again delay) on Host Level .
If there is no reason to keep the deadline, I will open a bug about it.
Best Regards,
Strahil Nikolov
