Re: ceph df space for rgw.buckets.data shows used even when files are deleted

I still see the issue, where the space is not getting deleted. gc process works sometimes but sometimes it does nothing to clean the GC, as there are no items in the GC, but still the space is used on the pool.

 

Any ideas what the ideal config for automatic deletion of these objects after the files are deleted.

Currently set to

 

    "rgw_gc_max_objs": "97",

Thanks Ben.

 

Is there are tuning param I need to use to fasten the process.

 

    "rgw_gc_max_objs": "32",

    "rgw_gc_obj_min_wait": "7200",

    "rgw_gc_processor_max_time": "3600",

    "rgw_gc_processor_period": "3600",

Ceph's RadosGW uses garbage collection by default.

 

Try running 'radosgw-admin gc list' to list the objects to be garbage collected, or 'radosgw-admin gc process' to trigger them to be deleted.

Folks,

 

Trying to test the S3 object GW. When I try to upload any files the space is shown used(that’s normal behavior), but when the object is deleted it shows as used(don’t understand this).  Below example.

 

Currently there is no files in the entire S3 bucket, but it still shows space used. Any insight is appreciated.

 

ceph version 10.2.6

 

NAME                                                    ID     USED       %USED     MAX AVAIL     OBJECTS

default.rgw.buckets.data             49     51200M      1.08         4598G               12800
