Yes, i have tasks in `radosgw-admin reshard list`.
And objects count in .rgw.buckets.index is increasing, slowly.
But i confused a bit. I have one big bucket with 161 shards.
…
"max_marker":
"0#,1#,2#,3#,4#,5#,6#,7#,8#,9#,10#,11#,12#,13#,14#,15#,16#,17#,18#,19#,20#,21#,22#,23#,24#,25#,26#,27#,28#,29#,30#,31#,32#,33#,34#,35#,36#,37#,38#,39#,40#,41#,42#,43#,44#,45#,46#,47#,48#,49#,50#,51#,52#,53#,54#,55#,56#,57#,58#,59#,60#,61#,62#,63#,64#,65#,66#,67#,68#,69#,70#,71#,72#,73#,74#,75#,76#,77#,78#,79#,80#,81#,82#,83#,84#,85#,86#,87#,88#,89#,90#,91#,92#,93#,94#,95#,96#,97#,98#,99#,100#,101#,102#,103#,104#,105#,106#,107#,108#,109#,110#,111#,112#,113#,114#,115#,116#,117#,118#,119#,120#,121#,122#,123#,124#,125#,126#,127#,128#,129#,130#,131#,132#,133#,134#,135#,136#,137#,138#,139#,140#,141#,142#,143#,144#,145#,146#,147#,148#,149#,150#,151#,152#,153#,154#,155#,156#,157#,158#,159#,160#»,
…
But in reshard list i see:
{
"time": "2018-07-15 21:11:31.290620Z",
"tenant": "",
"bucket_name": "my-bucket",
"bucket_id": "default.32785769.2",
"new_instance_id": "",
"old_num_shards": 1,
"new_num_shards": 162
},
"old_num_shards": 1 - it’s correct?
I hit a lot of problems trying to use auto resharding in 12.2.5
Which problems?

Hi,
Do you have on going resharding? 'radosgw-admin reshard list' should so you the
status.
Do you see the number of objects in .rgw.bucket.index pool increasing?
I hit a lot of problems trying to use auto resharding in 12.2.5 - I have
disabled it for the moment.
Thanks

Hi, guys.
I use Luminous 12.2.5.
Automatic bucket index resharding has not been activated in the past.
Few days ago i activated auto. resharding.
After that and now i see:
- very high Ceph read I/O (~300 I/O before activating resharding, ~4k now),
- very high Ceph read bandwidth (50 MB/s before activating resharding, 250 MB/s
now),
- very high RGW cache miss (400 count/s before activating resharding, ~3.5k
now).
For Ceph monitoring i use MGR+Zabbix plugin and zabbix-template from ceph
github repo.
For RGW monitoring i use RGW perf dump and my script.
Why is it happening? When is it ending?
