Scrubbing a lot

[German Anders <ganders@xxxxxxxxxxxx>]

Hi All,

I've maybe a simple question, I've setup a new cluster with Infernalis release, there's no IO going on at the cluster level and I'm receiving a lot of these messages:

I mean, all the time, and AFAIK these is because the scrub operation is like an fsck on the object level, so this make me think that it's not a normal situation. Is there any command that I can run in order to check this?

# ceph --cluster cephIB health detail
HEALTH_OK

Thanks in advance,

Best,

German
