dovecot - Dec 2022 - [SOLVED] Re: Error: Failed to get quota resource STORAGE: quota-fs: quotactl(Q_GETQUOTA, NFS:/home) failed: No such file or directory

Finally, I found the problem.
At build time, I had not installed the 'rpcgen' (RPM) package.
Initially, I installed the original RPM of the Rocky-Linux distribution, 
having the same problem.
I gather that the Rocky-Linux community is also creating the dovecot's 
rpm? without 'rpcgen' installed.

I'm curious if you would get the same issue with the dovecot23 
Ghettoforge packages in the gf-plus repo:

http://ghettoforge.org
https://mirror.ghettoforge.org/distributions/gf/el/9/plus/x86_64/

If so I wouldn't mind adding rpcgen as a build-dep to see if it helps.

A little bit of background on this since I've been looking into it.

Up through RHEL 7 the rpcgen binary was included in the glibc-common 
package, which is part of the standard build deps that are installed for 
all builds.  As of RHEL 8 this binary was moved to it's own package and 
was not installed automatically as it was previously.

This means that rquota (quota on NFS) worked fine up through EL7, but 
was broken for all builds starting with EL8.  Since dovecot builds fine 
without rquota support it appears that the issue never came up before, 
or at least it never got the notice of Red Hat.

The solution, as you point out is simple.  rpcgen simply needs to be 
added as a BuildRequires line in the dovecot.spec file and the package 
will once again be built with rquota support as it was before.

I filed a bug in Red Hat bugzilla, let's see if anything comes of it:
