Have a question about feature set used by rbdmap when it is used to map an RBD image.
I have a problem with mounted RBD-images, because that images are showed up as mapped using features from "Jewel" release, but installed ceph packages versions 12.2.12 (Luminous) and linux kernel 4.19.
$ ceph versions
{
"mon": {
"ceph version 12.2.12 (1436006594665279fe734b4c15d7e08c13ebd777) luminous (stable)": 3
},
"mgr": {
"ceph version 12.2.12 (1436006594665279fe734b4c15d7e08c13ebd777) luminous (stable)": 3
},
"osd": {
"ceph version 12.2.12 (1436006594665279fe734b4c15d7e08c13ebd777) luminous (stable)": 437
},
"mds": {},
"overall": {
"ceph version 12.2.12 (1436006594665279fe734b4c15d7e08c13ebd777) luminous (stable)": 443
}
}
$ ceph features
{
"mon": {
"group": {
"features": "0x3ffddff8eeacfffb",
"release": "luminous",
"num": 3
}
},
"osd": {
"group": {
"features": "0x3ffddff8eeacfffb",
"release": "luminous",
"num": 437
}
},
"client": {
"group": {
"features": "0x40106b84a842a52",
"release": "jewel",
"num": 3
},
"group": {
"features": "0x40107b86a842ada",
"release": "jewel",
"num": 10
},
"group": {
"features": "0x27018fb86aa42ada",
"release": "jewel",
"num": 1
},
"group": {
"features": "0x3ffddff8eeacfffb",
"release": "luminous",
"num": 4
}
}
}
MonSession(unknown.0 client-ip:0/3098420358 is open allow profile rbd, features 0x27018fb86aa42ada (jewel)) -
I have to enable "upmap" balancer because of some osd disks getting "near full" warnings but Jewel clients does not allowing me to set
$ ceph osd set-require-min-compat-client luminous
Error EPERM: cannot set require_min_compat_client to luminous: 3 connected client(s) look like jewel (missing 0xa00000000200000); 10 connected client(s) look like jewel (missing 0xa00000000200000); 1 connected client(s) look like jewel (missing 0x800000000000000); add --yes-i-really-mean-it to do it anyway
How to force this clients to user "Luminous" feature set?
