ctdb/ceph: add option to not register mutex rados helper as a service

2025-03-14T08:44:36+00:00

Add a new `-R` option (no-register) that will skip the step of
registering the lock helper as a ceph service. Ceph will treat the lock
helper more like a typical rados client. The `ceph -s` output will not
have ctdb listed under the services section (previous output):
```
  cluster:
    id:     5b81295a-fdec-11ef-a18f-525400220000
    health: HEALTH_WARN
            1 stray daemon(s) not managed by cephadm

  services:
    mon:  3 daemons, quorum ceph0,ceph1,ceph2 (age 6m)
    mgr:  ceph0.mkodry(active, since 85s)
    mds:  1/1 daemons up
    osd:  6 osds: 6 up (since 52m), 6 in (since 52m)
    ctdb: 1 daemon active (1 hosts)
```

Most importantly, this will avoid triggering health warnings from ceph
when cephadm discovers services that it did not create (or directly
manage) listed in the cluster.  Something we looked into hiding on the
cephadm side but proved quite tricky so it's better off not to try this
registration on cephadm managed clusters in the first place.

In addition, the `1 daemon active` bit is somewhat confusing when you
have a N (N>1) node ctdb cluster managed by cephadm. The fact that the
mutex helper only runs on one of those nodes at once is a low level
implementation detail that most users do not need and I assume could
confuse.

ctdb-scripts: Use nfs-utils' sm-notify instead of CTDB's smnotify

2024-08-29T22:48:33+00:00

CTDB's smnotify does not support IPv6 and is difficult to maintain.

So, create directories of files and pass them to NFS util's sm-notify.

There is an implied change here, because NFS utils sm-notify stopped
sending IP addresses as mon_name back in 2010:

  http://git.linux-nfs.org/?p=steved/nfs-utils.git;a=commitdiff;h=900df0e7c0b9006d72d8459b30dc2cd69ce495a5

This will change advice given in the wiki to use a hostname for the
cluster with round-robin DNS, since this is what is best supported.

Another behavioural change is that sm-notify only sends "up"
notifications with an odd state.

ctdb/ceph: Add optional namespace support for mutex helper

2024-06-14T06:40:37+00:00

RADOS objects within a pool can be associated to a namespace for
logical separation. librados already provides an API to configure
such a namespace with respect to a context. Make use of it as an
optional argument to the helper binary.
