hi,
i delete all pool by this script
arr=( $(rados lspools) )
for key in "${!arr[@]}"; do
ceph osd pool delete ${arr[$key]} ${arr[$key]}
--yes-i-really-really-mean-it
done
the output of ceph df after delete all pool,it seems this is no pool any
more,but still 251M usaged disk space.
[root@ceph03 ~]# ceph df
GLOBAL:
SIZE AVAIL RAW USED %RAW USED
92093M 91842M 251M 0.27
POOLS:
NAME ID USED %USED MAX AVAIL OBJECTS
[root@ceph03 ~]#
and the output of ceph osd df
[root@ceph03 ~]# ceph osd df
ID WEIGHT REWEIGHT SIZE USE AVAIL %USE VAR PGS
0 0.01459 1.00000 15348M 44384k 15305M 0.28 1.03 0

TOTAL 92093M 251M 91842M 0.27
so,why the data is still on the osd? dose it disapear after some time(eq.
10 min)? or the gc thread will process this?
