Hi,
I had to map a rbd from an ubuntu Trusty luminous client on an octopus cluster.
client dmesg :
feature set mismatch, my 4a042a42 < server's 100004a042a42, missing
1000000000000
I downgrade my osd tunable to bobtail but it still doesn't work
ceph osd crush show-tunables
{
"choose_local_tries": 0,
"choose_local_fallback_tries": 0,
"choose_total_tries": 50,
"chooseleaf_descend_once": 1,
"chooseleaf_vary_r": 0,
"chooseleaf_stable": 0,
"straw_calc_version": 1,
"allowed_bucket_algs": 22,
"profile": "bobtail",
"optimal_tunables": 0,
"legacy_tunables": 0,
"minimum_required_version": "hammer",
"require_feature_tunables": 1,

"has_v3_rules": 0,
"has_v4_buckets": 1,
"require_feature_tunables5": 0,
"has_v5_rules": 0
}
Thanks for your help.
