With the rados_cluster backend, you can also configure a nodeid to

If you set up a trivial rados_cluster with one (active/passive) host, I
expect it'll work more like you want. So, I'd set this in the NFSv4
block:
Using `rados_cluster` and sharing a `nodeid`...
NFSv4
{
RecoveryBackend = rados_cluster;
Minor_Versions = 1,2;
Grace_Period = 60;
}
[...]
RADOS_KV
{
UserId = "nfsmeta";
pool = "cephfs.tank.meta";
namespace = "ganesha";
nodeid = "nfs.storage";
}
...seems to have resolved the problem; failover times now seem to
track the `Grace_Period` setting.
Longer term, maybe we should allow rados_ng and rados_kv to set a
static
nodeid too? That would also probably fix this for people who just want a
simple active/passive cluster. Basically we'd just need to add a
get_nodeid operation for them.
Was I misusing `rados_ng`? All the docs I found said "use rados_ng for
active/passive configurations".
