Hi,
I just did a new Ceph installation and would like to enable the "read balancer".
However, the documentation requires that the minimum client version be reef. I checked this information through "ceph features" and came across the situation of having 2 luminous clients.
# ceph features
{
"mon": [
{
"features": "0x3f03cffffffdffff",
"release": "squid",
"num": 2
}
],
"mds": [
{
"features": "0x3f03cffffffdffff",
"release": "squid",
"num": 2
}
],
"osd": [
{
"features": "0x3f03cffffffdffff",
"release": "squid",
"num": 38
}
],
"client": [
{
"features": "0x2f018fb87aa4aafe",
"release": "luminous",
"num": 2
},
{
"features": "0x3f03cffffffdffff",
"release": "squid",
"num": 5
}
],
"mgr": [
{
"features": "0x3f03cffffffdffff",
"release": "squid",
"num": 2
}
]
}
I tryed to configure the minimum version to reef and received the following alert:
# ceph osd set-require-min-compat-client reef
Error EPERM: cannot set require_min_compat_client to reef: 2 connected client(s) look like luminous (missing 0x80000000); add --yes-i-really-mean-it to do it anyway
Is it ok do confirm anyway?
Which processes are still as luminous?
Rafael.
