Hey all,
I hope this is a simple question, but I haven't been able to figure it out. On one of our clusters there seems to be a disparity between the global available space and the space available to pools.
$ ceph df
GLOBAL:
SIZE AVAIL RAW USED %RAW USED
1528T 505T 1022T 66.94
POOLS:
NAME ID USED %USED MAX AVAIL OBJECTS
fs_data 7 678T 85.79 112T 194937779
fs_metadata 8 62247k 0 57495G 92973
libvirt_pool 14 495G 0.57 86243G 127313
The global available space is 505T, the primary pool (fs_data, erasure code k=2, m=1) lists 112T available. With 2,1 I would expect there to be ~338T available (505 x .67). Seems we have a few hundred TB missing. Thoughts?
Thanks,
jay
