Hi,
I'm observing following behavior on our Ceph clusters:
On Ceph cluster where I have enabled
osd_scrub_auto_repair = true
I can observe Spurious read errors warnings. On other Ceph clusters
where this option is set to false I don't see this warning. But on ohter
hand I have often scrub errors on Ceph clusters where this option is set
to false.
Can someone explain to me what this option (osd_scrub_auto_repair)
actually doing? Is it trying to rewrite bad blocks on disk also?
I also think that OSDs reported with Spurious read errors are OSDs where
repairing has happend. Is it right?
And the only workaround how to deal with this warning is to restart OSD
daemon. After this I never seen the same OSD daemon to be reported with
Spurious read errors.
Any ideas on questions above?
Thank you
