Dear ceph community, I’ve a ceph cluster which got upgraded from nautilus/pacific/…to reef over time. Now I added two new nodes to an existing EC pool as I did with the previous versions of ceph.
Now I face the fact, that the previous „backfilling tuning“ I’v used by
increasing injectargs --osd-max-backfills=XX --osd-recovery-max-active=YY dose
not work anymore.
With adjusting thous parameters the backfill was running with up to 2k +-
objects/s.
As I’m not (yet) familiar with the reef opiont the only speed up so far I found
is „ceph config set osd osd_mclock_profile high_recovery_ops“ which currently
runs the backfill with up to 600 opbjects/s.
My question: What is a best (simple) way to speed that backfill up ?
I’v tried to understand the custom profiles (?) but without success - and did
not apply anything other yet.
Thanks for feedback and suggestions ! Best regards . Götz
