Hi Thomas,
I’m afraid I can’t off
Hi Kévin, I am currently having a similar issue. in my env I have around 16
Linux vms (vmware) more or less equaly loaded accessing a 1PB ceph hammer
cluster (40 dn, 800 osds) through rbd.
Very often we have IO freeze on the VM xfs FS and we also continuously have
slow requests on osd ( up to
mon_osd_min_down_reports = 10

Hi Thomas,
do you have any RBD created as clone from another snapshot? If yes then this
would mean you still have some
overloading the
network or if my network switches that were having an issue.
Switches have been checked and they are showing no congestion issues or other
errors.
I really don’t know what to check or test, any idea is more than welcomed …
