Issue Recource Manager (Cgroups) does not show disk IO options

[vissgouvinas]

Server operating system version

Ubuntu 24.04

Plesk version and microupdate number

18.0.76

I have activated the Cgroups option on my Plesk installation and while i have options to limit both CPU and RAM it does not show the Disk IO at all.
I have already checked on that iotop works on the server as well.

Do you have any ideas?

Can you provide more details on the hardware and configuration?
Is it installed on a RAID partition? Is it a physical server or a VM? If a VM what is being used for virtualization?

Can you also run:

plesk sbin resctrl --features

 

[vissgouvinas]

The server is an raid 5 configuration, and it is a physical server, not a VM.

I runned and I got:
{"cpu": true, "cpuacct": true, "memory": true, "blkio": true, "vhosts_blkio": false}

 

[Martin Dias]

That does explain it then, Plesk Resource controller doesn't support IO limiting on RAID partitions.
And the option is not shown as Plesk detects that "vhosts_blkio": false
