[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.
