 |
|
Hi!
On my configurations, I set /etc/portage in NFS in order to share the configuration between the build server and the hosts.
On the server: | /etc/exports: | | /export/nas *(rw,no_subtree_check,no_root_squash) |
on the client: | /etc/fstab: | | servername:/nas /data/nas nfs4 _netdev,rw 0 0 |
I recently resetted the FEATURES variable in /etc/portage/make.conf to a more default config (the settings were all different on all configs, because of history) to | Code: | | FEATURES="candy sandbox parallel-fetch -distcc -distcc-pump -binpkg-multi-instance" |
since then, linux-firmware fails copying the savedconfig files from portage build dir to /etc/portage/savedconfig:
| Code: | * Checking existence of "/etc/portage/savedconfig/sys-kernel/linux-firmware-20230404" ...
* Found "/etc/portage/savedconfig/sys-kernel/linux-firmware-20230404"
* Building using saved configfile "/etc/portage/savedconfig/sys-kernel/linux-firmware-20230404"
cp: preserving permissions for ‘linux-firmware.conf’: Operation not supported
* ERROR: sys-kernel/linux-firmware-20230404::gentoo failed (prepare phase):

* Call stack:

* cp -pPR "${found}" "$1" || die "Failed to restore ${found} to $1";

* S: '/var/tmp/portage/sys-kernel/linux-firmware-20230404/work/linux-firmware-20230404'
>>> Failed to emerge sys-kernel/linux-firmware-20230404, Log file: |
all files belong to portage:portage and user/group portage have the same UID/GID on server and client.
as user, I have no problem: | Code: | $ cp -pv hello_test /data/nas/xavier/temp/ ; ls -la hello_test /data/nas/xavier/temp/hello_test
'hello_test' -> '/data/nas/xavier/temp/hello_test'
-rw-r--r-- 1 xavier xavier 0 15 mai 08:40 /data/nas/xavier/temp/hello_test
-rw-r--r-- 1 xavier xavier 0 15 mai 08:40 hello_test |
What is wrong with my config?

Maybe add
no_all_squash
in /etc/exports.
You need idmapd.
Plz set it in
/etc/conf.d/nfs
and
/etc/conf.d/nfsclient.
Plz edit /etc/idmapd.conf to reflect your domain.
According to Arch this might not be enough

Thanks!
I see idmapd is not configured/started.
I will take some time to configure and test it.
I'll come later back with the results/solution
