Re: Does jewel 10.2.10 support filestore_split_rand_factor?

[David Turner <drakonstein@xxxxxxxxx>]

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?

No, it is supported in the next version of Jewel http://tracker.ceph.com/issues/22658

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",
