Re: [ceph-users] Resolving Large omap objects in RGW index pool

Hi, Having spent some time on the below issue, here are the steps I took to resolve the "Large omap objects" warning. Hopefully this will help others who find themselves in this situation. I got the object ID and OSD ID implicated from the ceph cluster logfile on the mon. I then proceeded to th

Are you running multiple active MDS daemons? On MDS host issue "ceph-daemon mds.X config set debug_mds 20" for maximum logging verbosity. > On 16.10.2018, at 19:23, Florent B wrote: > > Hi, > > A few months ago I sent a message to that list about a problem with a > Ceph + Dovecot setup. > > B

Re: [ceph-users] Disabling RGW Encryption support in Luminous

That's not currently possible, no. And I don't think it's a good idea to add such a feature; if the client requests that something be encrypted, the server should either encrypt it or reject the request. There is a config called rgw_crypt_s3_kms_encryption_keys that we use for testing, though,

Hi, I have a cluster serving rbd and cephfs storage for a period of time. I added rgw in the cluster yesterday and wanted it to server object storage. Everything seems good. What I'm confused is how to calculate the pg/pgp number. As we all know, the formula of calculating pgs is: Total PGs = ((
