Hi,
I've moved all files from a CephFS data pool (EC pool with frontend
cache tier) in order to remove the pool completely.
Some objects are left in the pools ('ceph df' output of the affected pools):
cephfs_ec_data 19 7565k 0 66288G 13
Listing the objects and the readable part of their 'parent' attribute:
# for obj in $(rados -p cephfs_ec_data ls); do echo $obj; rados -p
cephfs_ec_data getxattr parent | strings; done
10000f6119f.00000000
10000f6119f
stray9
10000f63fe5.00000000
10000f6119f
stray9
10000f61196.00000000
10000f6119f
stray9
.......
The names are valid CephFS object names. But the parent attribute does
not contain the path of file the object belongs to; instead the string
'stray' is the only useful information (without dissecting the binary
content of the parent attribute).
What are those objects and is it safe to remove the pool in this state?
Regards,
Burkhard
