Hello, Yes it is, this is the output: "default.rgw.log:gc" From: Thomas Bennett <thomas@xxxxxxxxx> Sent: Wednesday, May 20, 2020 5:44 PM To: Szabo, Istvan (Agoda) <Istvan.Szabo@xxxxxxxxx> Cc: ceph-users <ceph-users@xxxxxxx> Subject: Re: Re: Large omap Email received from outside the company. If in doubt don't click links nor open attachments! ________________________________ Hi, Have you looked at omaps keys to see what's listed there? In our configuration, the radosgw garbage collector uses the default.rgw.logs pool for garbage collection (radosgw-admin zone get default | jq .gc_pool). I've seen large omaps in my default.rgw.logs pool before when I've deleted large amounts of s3 data and there are many shadow objects that still need to be deleted by the garbage collector.

If you do use them, perhaps set "rgw usage max user shards" to something larger than the default 1. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx<mailto:ceph-users@xxxxxxx> To unsubscribe send an email to ceph-users-leave@xxxxxxx<mailto:ceph-users-leave@xxxxxxx> -- Thomas Bennett Storage Engineer at SARAO ________________________________ This message is confidential and is for the sole use of the intended recipient(s).
