[ceph-users] Re: Massive OMAP remediation

Luminous 12.2.11 is still default using bluefs_buffered_io = false, which will 
disable the kernel side cache for rocksdb. 
It's possible that your NVMe is saturated with the massive rocksdb workload 
when bluefs_buffered_io is disabled.
So one way you could try is to set the bluefs_buffered_io = true on those OSDs 
that hold the large OMAP object.
