Hi,
I am using ceph version 13.2.6 (mimic) on test setup trying with cephfs.
my ceph health status showing warning.
My current setup:
3 OSD node each with a single disk, recently I added one more disk in one
of the node and ceph cluster status showing warning.
I can see the progress but it was more than 12 hours but still its moving
objects.
How to increase the speed of moving objects?

If the disks can handle it, increase the max_backfills (seem to be 1 now)
to allow more than one OSD to feed data into the new OSD.
Also, more drives mean more parallelism when moving data around, so the
smaller the cluster is, the less it can spread the load of moving data.

May the most significant bit of your life be positive.

Hey hey,
First of all: 10GBps connection.
Then, some magic commands:
# ceph tell 'osd.*' injectargs '--osd-max-backfills 32'
# ceph tell 'osd.*' injectargs '--osd-recovery-max-active 12'
# ceph tell 'osd.*' injectargs '--osd-recovery-op-priority 63'

how about also increasing osd_recovery_threads?

I don't think MIMIC support this attribute:
