Thank you.
I will look into the script.
For fixed object size application(rbd,cephfs), do you think it is good idea to
pre-split the folders to the point when each folder contains about 1-2k
objects when the cluster is full. I think by doing this can avoid the performce
impact of splitting folder when clients are writing data into the cluster.

You could randomize your ceph.conf settings for filestore_merge_threshold and
filestore_split_multiple. It's not pretty, but it would spread things out.
You could even do this as granularly as you'd like down to the individual OSDs
while only having a single ceph.conf file to maintain.
I would probably go the route of manually splitting your subfolders, though.
I've been using this [1] script for some time to do just that. I tried to make
it fairly environment agnostic so people would have an easier time implementing
it for their needs.

Thanks.
Is there any workaround for 10.2.10 to avoid all osd start spliting at the same
time?

filestore_split_rand_factor?
Hi list,
The document page of jewel has filestore_split_rand_factor config but I can't
find the config by using 'ceph daemon osd.x config'.
ceph version 10.2.10 (5dc1e4c05cb68dbf62ae6fce3f0700e4654fdbbe)
ceph daemon osd.0 config show|grep split
"mon_osd_max_split_count": "32",
"journaler_allow_split_entries": "true",
"mds_bal_split_size": "10000",
"mds_bal_split_rd": "25000",
"mds_bal_split_wr": "10000",
"mds_bal_split_bits": "3",
"filestore_split_multiple": "4",
"filestore_debug_verify_split": "false",
