Both server and clients are running most recent 12-CURRENT. The server is
exporting a ZFS volume via NFSv4. I recently copied that volume from another
volume via zfs send/receive from one vilume on the same server to another
volume, created on another sorage device.
The specific volume worked before in the environment I use. It is exported via
NFSv4 by the server with -maproot=www:www and read/writeable by only one
specific host and imported via NFSv4 autofs by that specific host. The purpose
is to synchronize via "rsync -rv" packages created via poudriere on a very
fast smaller machine to the fileserver. The owner of the volume's folder
hierarchy is "www:www" with unaltered, proper access rights.
The last time the sync worked was July, 20th. Now, since a couple of days or
weeks, I get an error: permission denied. root is the user trying to rsync
from the poudriere creator host to write the packages folder hierarchy and
packages to the autofs volume, but the procedure fails.
I have no clue what changed. I checked whether the ZFS volume is locked in
any way after it has been sent/received, but it isn't. It looks like an
ordinary volume and locally (from the perspective of the fileserver) creation
and deletion of files is possible.
What do I miss here?
The fact that this procedure worked with 11-CURRENT and 11-ALPHA weeks ago as
it is, makes me suspect a bug or fundamentaly change in the bahviour or - there
is a hidden lock when zfs send/receive is used I didn't realizes to relief.
Thanks in advance for help and considerations,
