Re: [ceph-users] Using s3 (radosgw + ceph) like a cache
This is how we use ceph/ radosgw. I'd say our cluster is not that reliable, but it's probably mostly our fault (no SSD journals, etc). However, note that deletes are very slow in ceph. We put millions of objects in very quickly and they are verrry slow to delete again especially from RGW because it has to update the index too. -Ben On Mon, Apr 25, 2016 at 2:15 AM, Dominik Mostowiec < dominikmostow...@gmail.com> wrote: > Hi, > I thought that xfs fragmentation or leveldb(gc list growing, locking, > ...) could be a problem. > Do you have any experience with this ? > > --- > Regards > Dominik > > 2016-04-24 13:40 GMT+02:00 : > > I do not see any issue with that > > > > On 24/04/2016 12:39, Dominik Mostowiec wrote: > >> Hi, > >> I'm curious if using s3 like a cache - frequent put/delete in the > >> long term may cause some problems in radosgw or OSD(xfs)? > >> > >> - > >> Regards > >> Dominik > >> ___ > >> ceph-users mailing list > >> ceph-users@lists.ceph.com > >> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > >> > > > > ___ > > ceph-users mailing list > > ceph-users@lists.ceph.com > > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > > > > -- > Pozdrawiam > Dominik > ___ > ceph-users mailing list > ceph-users@lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
Re: [ceph-users] Using s3 (radosgw + ceph) like a cache
Hi, I thought that xfs fragmentation or leveldb(gc list growing, locking, ...) could be a problem. Do you have any experience with this ? --- Regards Dominik 2016-04-24 13:40 GMT+02:00 : > I do not see any issue with that > > On 24/04/2016 12:39, Dominik Mostowiec wrote: >> Hi, >> I'm curious if using s3 like a cache - frequent put/delete in the >> long term may cause some problems in radosgw or OSD(xfs)? >> >> - >> Regards >> Dominik >> ___ >> ceph-users mailing list >> ceph-users@lists.ceph.com >> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com >> > > ___ > ceph-users mailing list > ceph-users@lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com -- Pozdrawiam Dominik ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

[ceph-users] Using s3 (radosgw + ceph) like a cache
Hi, I'm curious if using s3 like a cache - frequent put/delete in the long term may cause some problems in radosgw or OSD(xfs)? - Regards Dominik ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
