Hi,
how big are those PGs? If they're huge and are deep-scrubbed, for
example, that can cause significant delays. I usually look at 'ceph pg
ls-by-pool {pool}' and the "BYTES" column.
Zitat von Boris <bb@xxxxxxxxx>:
Hi,
currently we encouter laggy PGs and I would like to find out what is
causing it.
I suspect it might be one or more failing OSDs. We had flapping OSDs and I
synced one out, which helped with the flapping, but it doesn't help with
the laggy ones.
Any tooling to identify or count PG performance and map that to OSDs?
