Yea, that was a cluster created during firefly... Wish there was a good article on the naming and use of these, or perhaps a way I could make sure they are not used before deleting them. I know RGW will recreate anything it uses, but I don’t want to lose data because I wanted a clean system. -Brent -----Original Message----- From: Gregory Farnum <gfarnum@xxxxxxxxxx> Sent: Monday, April 15, 2019 5:37 PM To: Brent Kennedy <bkennedy@xxxxxxxxxx> Cc: Ceph Users <ceph-users@xxxxxxxxxxxxxx> Subject: Re: Default Pools On Mon, Apr 15, 2019 at 1:52 PM Brent Kennedy <bkennedy@xxxxxxxxxx> wrote: > > I was looking around the web for the reason for some of the default pools in Ceph and I cant find anything concrete. Here is our list, some show no use at all.

I think they're all used (although they may report sizes of 0, as they mostly make use of omap). > metadata Except this one used to be created-by-default for CephFS metadata, but that hasn't been true in many releases. So I guess you're looking at an old cluster? (In which case it's *possible* some of those RGW pools are also unused now but were needed in the past; I haven't kept good track of them.) -Greg _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
