The solution would be :
"convert-usrmerge can be run in a chroot on the NFS server"
If your NFS server is not Linux-based, carefully copy the files over a
Linux machine, chroot+convert there, then move back to the NFS server.
Make backups ;)

As per the why, I don't know.
Maybe the symlink handling by NFS ?
Reading the script "/usr/lib/usrmerge/convert-usrmerge", you get the
reasons why it fails :
142 # The other cases are more complex and there are some corner
cases that
143 # we do not try to resolve automatically.
144
145 # both source and dest are links
[...]
168 # the source is a link
[...]
175 # the destination is a link
[...]
191 # both source and dest are directories
192 # this is the second most common case
You may change the script to detect where/why it fails, so edit
fatal("Both $n and /usr$n exist");
to
fatal("Both $n and /usr$n exist - err line 145");
fatal("Both $n and /usr$n exist - err line 168");
Also found this on
"https://en.opensuse.org/openSUSE:Usr_merge#Known_Problems"; :
- "File systems that do not support RENAME_EXCHANGE such as ZFS or NFS
cannot perform live conversion (Bug 1186637)"
- "Conversion fails if there's a mount point below
(/usr)/{bin,sbin,lib,lib64}"
Good luck
