Hi all,
is there a way to limit the throughput (or the number of operations per seconds) of a
block device?
I ask because I've a couple of misconfigured VMs that are performing a lot of disk
activity (swapping I'd bet but I haven't access to their OS). Since their storage
is on a NFS share they are slowing down other VMs on the same share.
Thank you.
Davide.
Hi,
there is <blkiotune> [1] that controls the throughput for the whole
domain and <iotune> [2] that controls it for each block device.
