As far as i know,there is no way to set the compat Level below the actual. - Mehmet Am 2. September 2019 12:07:14 MESZ schrieb "潘东元" <dongyuanpan0@gmail.com>:

hi,every one, my ceph version 12.2.12，I want to set require min compat client luminous,I use command #ceph osd set-require-min-compat-client luminous but ceph report:Error EPERM: cannot set require_min_compat_client to luminous: 4 connected client(s) look like jewel (missing 0xa00000000200000); add --yes-i-really-mean-it to do it anyway [root@node-1 ~]# ceph features { "mon": { "group": { "features": "0x3ffddff8eeacfffb", "release": "luminous", "num": 3 } }, "osd": { "group": { "features": "0x3ffddff8eeacfffb", "release": "luminous", "num": 15 } }, "client": { "group": { "features": "0x40106b84a842a52", "release": "jewel", "num": 4 }, "group": { "features": "0x3ffddff8eeacfffb", "release": "luminous", "num": 168 } } }

so,I run command: [root@node-1 gyt]# ceph osd set-require-min-compat-client luminous --yes-i-really-mean-it set require_min_compat_client to luminous

but now,I want to set require min compat client jewel,I use command：

[root@node-1 gyt]# ceph osd set-require-min-compat-client jewel Error EPERM: osdmap current utilizes features that require luminous; cannot set require_min_compat_client below that to jewel

what‘s the way we are set luminous chang to jewel？ _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
