 Posted: Sun Oct 27, 2024 9:11 am Post subject: [solved] nfsdcld & missing nfs4recoverydir |
 |
|
Using nfs4 i found that i got some errors indicating that client tracking is not configured consistently as i removed the legacy client tracking from kernel configuration.
I understood that the current way would be to run nfsdcld (https://bugs.gentoo.org/935724)
but when i try to start the daemon i get this (indicating proc entry missing - not sure on the inotify impact yet)
I did not find which part of kernel config or tool would be responsible for creating this.

Anyone has a hint on what i am missing?
Edit: Small progress, after mounting this fstab entry, i could start the nfsdcld. Not sure if this is the proper way to go and i just missed this from instructions or not
| Code: | | rpc_pipefs /var/lib/nfs/rpc_pipefs rpc_pipefs defaults 0 0 |
Edit2: Marking as solved with manual creation of conf.d/nfs file (see details below)

This is the job of rpc.idmapd service.
I have this :
/etc/conf.d/nfs :
| Code: | # Optional services to include in default `/etc/init.d/nfs start`
# For NFSv4 users, you'll want to add "rpc.idmapd" here.
NFS_NEEDED_SERVICES="rpc.idmapd nfsdcld" |
/etc/init.d/nfsdcld :
| Code: | #!/sbin/openrc-run
# Copyright 2024 Gentoo Authors
# Distributed under the terms of the GNU General Public License v2
name="nfsdcld daemon"
description="NFSv4 Client Tracking Daemon"
command=/usr/bin/nfsdcld
command_args="${nfsdcld_args}" |
My paths are :
/var/lib/nfs/v4recovery/
/var/lib/nfs/nfsdcld/main.sqlite
as expected here : https://gitweb.gentoo.org/repo/gentoo.git/tree/net-fs/nfs-utils/nfs-utils-2.7.1.ebuild#n198 |

Makes sense but also opens new questions on my side.
I updated nfs-utils on 19th of Oct 2024 according to eix output.
Neither before this nor afterwards i had /etc/conf.d/nfs.conf (with .conf or without) according to my snapper history.
Also when looking on my /etc/config.archive/etc/conf.d folder i see the last entries for nfs from 2011/2010.
I have it now only because of my attempts to setup nfs with mTLS where i added | Code: | | OPTS_RPC_NFSD="8 -V 4 -V 4.2" |
And also i do not have /etc/init.d/nfsdcld at all (which i assumed was due to the mentioned bug).
It is not part of files of nfs-utils, is this created during build and should be placed?
Will look into last build log of nfs-utils or try to merge and check later if i have a bit more time.
Thanks again for this hint - some things seem odd on that system. |

You're right, this package is lacking a few things.
nfs.conf was deleted recently, don't know why :
https://gitweb.gentoo.org/repo/gentoo.git/tree/?id=b088105deeb5406690698f092535767f71546570
https://forums.gentoo.org/viewtopic-t-1170985-start-0-postdays-0-postorder-asc-highlight-.html
my nfs.conf for an example, nfsv4only ("need portmap" commented in /etc/init.d/nfs)
| Code: |
# If you wish to set the port numbers for lockd,
# please see /etc/sysctl.conf
# Optional services to include in default `/etc/init.d/nfs start`
# For NFSv4 users, you'll want to add "rpc.idmapd" here.
NFS_NEEDED_SERVICES="rpc.idmapd nfsdcld"

# ex. OPTS_RPC_MOUNTD="-p 32767"

rc_need="!net !portmap !rpc.statd" |
yes, /etc/init.d/nfsdcld is not provided either, maybe because nfsv3 is certainly still widely used.
I know nothing about nfs/mTLS. |

mTLS i tried based on reading arch wiki and summarized it here https://forums.gentoo.org/viewtopic-t-1171441.html
Will check the links later this week and setup nfs.conf accordingly, on a quick glane on the other thread there seem to be conclusion that i was removed intentionally but it seems odd to not have at least a commented sample with hints on what one might want to activate based on needs.
Thanks again |
