Package: nfs-kernel-server Version: 1:2.8.3-1 Severity: normal

Dear Maintainer,

I'm using SysVrc and updated an NFS server from Deb12 to Deb13. This is a machine which heavy load due to Veeam Backup & Replication repositories.

To keep up, I had changed /etc/default/nfs-kernel-server to increase RPCNFSDCOUNT to a number high enough to stop syslog messages about incomplete data transfers.

Since Deb13, RPCNFSDCOUNT is no longer used. Culprit is that in /etc/init.d/nfs-kernel-server lines 99 to 101, /sbin/rpc.nfsd is no longer given the $RPCNFSDCOUNT variable, as it was in the Debian 12 initscript.

This was an intentional change. Support for /etc/default/nfs-kernel-server was deprecated in bookworm (as documented in NEWS) and removed in trixie.

Sorry, I really should go back to the source before trying to answer from memory.

Support for settings in /etc/default that are redundant with settings in nfs.conf was removed in trixie.
All the other settings in /etc/default continue to be supported.

Hello Ben,

there is no mentioning of this IMHO breaking change in a Deb12's /usr/share/doc/nfs-kernel-server/NEWS.Debian.gz. Besides… usual systems can have many hundreds of NEWS files. Nobody is able to read those during a system upgrade, and there was no mentioning of this fact in neither https://www.debian.org/releases/stable/release-notes/index.en.html nor https://www.debian.org/releases/stable/release-notes/issues.en.html — I always read these pages very carefully before upgrading. Maybe, I'm part of a minority with my setup…

I presume the new intended way of handling things is editing /etc/nfs.conf, and setting the threads parameter within [nfsd]. It would have been really helpful if the package upgrade scripts would do this parameter migration if they have been changed, and give a warning with e. g. dialog.

I'll revisit the initscript and /etc/default, and clean up manually, so the Deb14-Upgrade will go smoothly.

Thanks for the insight!

It's in nfs-common's NEWS because this change affected both client and server usage. But it was not a breaking change, and was not mentioned in release-notes because...

...the upgrade to bookworm did include an automatic migration.
