Hi everyone,
we have recently deployed a Luminous(12.2.1) cluster on Ubuntu - three
osd nodes and three monitors, every osd has 3x 2TB SSD + an NVMe drive
for a blockdb. We use it as a backend for our Openstack cluster, so we
store volumes there. IN the last few days, the read op/s rose to around
10k-25k constantly(it fluctuates between those two) and it doesn't seem
to go down. I can see, that the io/read ops come from the pool where we
store VM volumes, but i can't source this issue to a particular volume.
Is that even possible? Any experiences with debugging this? Any info or
advice is greatly appreciated.
Thanks
Josef Zelenka
