This is usual feature mismatch stuff , the inbox krbd you are using is not supporting Jewel. Try googling with the error and I am sure you will get lot of prior discussion around that..

Somnath, Thanks. I am trying your suggestion. See the commands below. Still it doesn’t seem to go. I am missing something here… Thanks, - epk ============= [test@ep-c2-client-01 ~]$

The default format of rbd image in jewel is 2 along with bunch of other deatures enabled , so, you have following two option: 1. create a format 1 image –image-format 1 2. Or, do this in the ceph.conf file [client] or [global] before creating image.. rbd_default_features = 3 Thanks & Regards Somnath From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of EP Komarla All, I am creating an image and mapping it. The below commands used to work in Hammer, now the same is not working in
Jewel. I see the message about some feature set mismatch – what features are we talking about here? Is this a known issue in Jewel with a workaround? Thanks, - epk ========= [test@ep-c2-client-01 ~]$
