you are thinking of "osd_snap_trim_sleep" which is indeed a very helpful

Hi, in fact it highly depend on your ceph underlying installation (both HW

Would you be willing to share more information on your needs and design?
How many IOPS are you looking at? Which processors and disks are you using?

Nah, I would use one Filesystem unless you can’t. The backtrace does create
another object but IIRC it’s a maximum one IO per create/rename (on the
file).

Thanks for clarifying that, Gregory.
As said before, we use the file layout to resolve the difference of
workloads in those 2 different directories in cephfs.
Would you recommend using 2 filesystems instead? By doing so, each fs would
have it's default data pool accordingly.

How long is “too long”? 800MB on an SSD should only be a second or three.
I’m not sure if that’s a reasonable amount of data; you could try
compacting the rocksdb instance etc. But if reading 800MB is noticeable I
would start wondering about the quality of your disks as a journal or

The backtrace object Zheng referred to is used only for resolving hard
links or in disaster recovery scenarios. If the default data pool isn’t
available you would stack up pending RADOS writes inside of your mds but
the rest of the system would continue unless you manage to run the mds out

Does that mean that, when using such feature, our data integrity relies now
on both data pools' integrity/availability?
We currently use such feature in production for dovecot's index files, so

Very. Very bad idea. When your ssd/nvme dead you lost your linux box.
