I wanted to report back on this since I've made some progress on
fixing this issue.
After converting every OSD on a single server to use a 2K block size,
I've been able to cross 90% utilization without running into the 'No
space left on device' problem. They're currently between 51% and 75%,
but
So I'm running into this issue again and after spending a bit of time
reading the XFS mailing lists, I believe the free space is too
fragmented:
[root@den2ceph001 ceph-0]# xfs_db -r "-c freesp -s" /dev/sdb1
from to extents blockspct
1 1 85773 85773 0.24
2
The filesystem isn't as full now, but the fragmentation is pretty low:
[root@den2ceph001 ~]# df /dev/sdc1
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdc1486562672 270845628 215717044 56% /var/lib/ceph/osd/ceph-1
[root@den2ceph001 ~]# xfs_db -c frag -r /dev
How fragmented is that file system?
