Bug #39704
closedWhen running multiple filesystems, directories do not fragment
0%
Description
Nautilus, Ubuntu 18.04.2, HWE kernel 4.18.0-18-generic.
I have created multiple ceph filesystems:
root@mc-3015-201:/mnt/ceph1# ceph fs ls
name: cephfs_bs_lvm, metadata pool: cephfs_metadata, data pools: [cephfs_data ]
name: cephfs1, metadata pool: cephfs1_metadata, data pools: [cephfs1_data ]
name: cephfs2, metadata pool: cephfs2_metadata, data pools: [cephfs2_data ]
name: cephfs3, metadata pool: cephfs3_metadata, data pools: [cephfs3_data ]
name: cephfs4, metadata pool: cephfs4_metadata, data pools: [cephfs4_data ]
I can create 1 million files in cephfs_bs_lvm, the first one created.
But when I try to do the same on any of the others, I get ENOSPC at exactly 100k.
This implies I am hitting mds_bal_fragment_size_max, and that the directories are not fragmenting.
Please let me know if any other information is required.
