Hello,
I have a questions regarding the bucket index:
1) As far as know index of a given bucket is the single RADOS object
and it lives in OSD omap. But does it get replicated or not?
2) When trying to copy bucket index pool to some other pool i get the
following error:
$ rados cppool ed-1.rgw.buckets.index test
ed-1.rgw.buckets.index:.dir.06ee966c-5b48-4c53-8ed8-36bbf53204f5.171499.1
=> test:.dir.06ee966c-5b48-4c53-8ed8-36bbf53204f5.171499.1
error copying object: (2) No such file or directory
error copying pool ed-1.rgw.buckets.index => test: (34) Numerical
result out of range
and the object is not getting copied. Btw, this particular index
servers as an index of bucket with almost 19 million objects and it is
not sharded.
$ ceph df | grep -e ed-1.rgw.buckets.data -e NAME
NAME ID USED %USED MAX AVAIL
OBJECTS
ed-1.rgw.buckets.data 16 52998G 4.96 769T
38414882
