Hi,
I encountered an issue similar to bug 19438
<http://tracker.ceph.com/issues/19438> .
I have an attachment directory in cephfs and one of the sub
directory includes about 20-30 thousand small files from 100k-1M
each. When I created file in this sub directory it alarms:
"cannot touch ‘attachment/sme/2018-09/test’: No space left on device"
There's no error in any ceph log. "ceph -s" returns "HEALTH_OK".
Besides, "mds_bal_frag" is set to "true".
# ceph daemon mds.ceph-mds config show | grep mds_bal_frag
"mds_bal_frag": "true",
"mds_bal_fragment_fast_factor": "1.500000",
"mds_bal_fragment_interval": "5",
"mds_bal_fragment_size_max": "500000",
ceph version 12.2.5, using kernel client.
Anything I can do to solve this issue?
Thanks
