Re: gluster daemons missing in debian buster 10.5 after glusterfs 7.8-1 installed?

[Kaleb Keithley <kkeithle@xxxxxxxxxx>]

tl;dnr: some linux distribution package guidelines say it's bad to automatically start services after installing.

long answer:

The package layout of the gluster packages changed in the base packages of newer Debian and Ubuntu releases. To be compatible — e.g. to update from Buster's base glusterfs to the gluster community packages — the Gluster community packages switched to the same layout. If they used to start automatically before, and they don't now, that's almost certainly why.

For the most part we just copied the base package debian files, so whatever the base packages do, or don't do, that's what the community packages also do, including starting, or not starting the daemons.

Hello Kaleb,

thanks for your email.

i think i found the problem.

In previous releases, when gluster packages are installed, they are started.

In the case of 7.8-1 version i needed to check and enable them:

systemctl is-enabled xx

systemctl enable xx

systemctl start xx

where xx={glusterd.service, glustereventsd.service}

But i still miss the glusterfssharedstorage.service - i think it will be activated when a glusterfs client locally mounts a created volume.

I will go on and recheck all my steps. i will update this thread later.

Kind regards,

peterk

-rw-r--r-- 1 root root  464 Jul 21 05:16 glusterd.service
root@stretchtobluster:/lib/systemd/system#

Is something missing here?

The Gluster executables (including the daemons: glusterd, glusterfsd, glusterfs, and glustereventsd) aren't installed in /lib/systemd/...  and never have been.

They are installed in /usr/sbin/, and /usr/lib/$arch-linux-gnu/glusterfs/ or on newer Debian in /usr/libexec/glusterfs/

What do you think is missing?
