Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
I have an nfs export: /mnt/Backup Hostname(no_root_squash,ro,mp)
It exports this drive, LABEL=Backup /mnt/Backup
btrfs noatime,compress-force=zstd:99
I have a locally mounted drive, /mnt/Mirror (LABEL=Mirror
/mnt/Mirror btrfs compress-force=zstd:99,noatime,nofail)
I mount the nfs share: mount Hostname:/mnt/Backup /mnt/Backup.
I cp a file from one to the other, cp -av
/mnt/Backup/snaps/elden/90/info.xml
/mnt/Mirror/snaps/elden/90/info.xml.
Under coreutils-9.1 I get no error. Under coreutils-9.2 I get cp:
preserving permissions for ‘/mnt/Mirror/snaps/elden/90/info.xml’:
Operation not supported
In both cases the resulting copy looks like this:
# ls -l /mnt/*/snaps/elden/90/info.xml
-rw------- 1 root root 184 Apr 17 10:52 /mnt/Backup/snaps/elden/90/info.xml
-rw------- 1 root root 184 Apr 17 10:52 /mnt/Mirror/snaps/elden/90/info.xml
I git bisected with gentoo's live ebuild coreutils-9999
# first bad commit: [28a85116feef1f9a6f31c5ab8cfe50d7aa8d6fc4] build:
update gnulib submodule to latest
# cp --version
cp (GNU coreutils) 9.2
