Thank you for the response. It seems to me it is a transient situation.
At this moment, I regained access to most, but not all buckets/index
objects. But the overall performance dropped once again - I already have
huge performance issues.
Regards.

Do the client key have access to the base pool? Something similar bit
us when adding a caching tier. Since the cache tier may be proxying
all the I/O, the client may not have had access to the base pool and
it still worked ok. Once you removed the cache tier, it could no
longer access the pool.

Dear all,
I had to move .rgw.buckets.index pool to another structure; therefore, I
created a new pool .rgw.buckets.index.new ; added the old pool as cache
pool, and flushed the data.
Up to this moment everything was ok. With radosgw -p df, I saw the
objects moving to the new pool; the moved objects where ok, I could list
omap keys and so on.
When everything got moved, I removed the overlay cache pool. But at this
moment, the objects became unresponsive:
[(13:39:20) ceph@spchaog1 ~]$ rados -p .rgw.buckets.index listomapkeys
.dir.default.198764998.1
error getting omap key set .rgw.buckets.index/.dir.default.198764998.1: (5)
Input/output error
That happens to all objects. When trying the access to the bucket through
radosgw, I also get problems:
[(13:16:01) root@spcogp1 ~]# radosgw-admin bucket stats --bucket="mybucket"
error getting bucket stats ret=-2
Looking at the disk, data seems to be there:
[(13:47:10) root@spcsnp1 ~]# ls
/var/lib/ceph/osd/ceph-23/current/34.1f_head/|grep 198764998.1
\.dir.default.198764998.1__head_8A7482FF__22
Does anyone have a hint? Could I have lost ownership of the objects?
Regards.
