Hi,
I tried to run this command with failure:
root@ld3955:/mnt/rbd# ceph osd set-require-min-compat-client luminous
Error EPERM: cannot set require_min_compat_client to luminous: 6
connected client(s) look like jewel (missing 0xa00000000200000); 19
connected client(s) look like jewel (missing 0x800000000000000); 23
connected client(s) look like jewel (missing 0x800000000000000); add
--yes-i-really-mean-it to do it anyway
root@ld3955:/mnt/rbd# ceph features
{
"mon": [

"features": "0x3ffddff8ffacffff",

],
"mds": [

"osd": [

"release": "jewel",
"num": 6
},
{
"features": "0x27018eb84aa42a52",
"release": "jewel",
"num": 19
},
{
"features": "0x27018fb86aa42ada",
"release": "jewel",

},
{
"features": "0x3ffddff8ffacffff",
"release": "luminous",
"num": 35
}
],
"mgr": [
{
"features": "0x3ffddff8ffacffff",
"release": "luminous",
"num": 3
}
]
}
But I think the number of clients older than Luminous is incorrect.
I'm running 98% of the clients with SLES 12SPx, and therefore the
question is:
Can you confirm in which SLES 12 release the function upmap is supported?
And is it safe to execute ceph osd set-require-min-compat-client
luminous --yes-i-really-mean-it? What happens to the clients then?
Regards
Thomas
