Very slow ceph recovery
Hello,
I've got a problem with one OSD. I've added 3 more OSD and started objects recovery.
Recovery IO is quite fast(~50mb/s) but degraded objects decreasing incredibly slowly(~0,03% per minute).
My ceph cluster have 7 disks 2TB HDD with only ~1TB data.
Can I ask why this could take so long? Now i have 20% degraded objects, with this speed recovery 1TB data will took about 10 hours.
Is there any way to speed up this process?
