Hello,

i've PVE installed with ZFS. For home and other have exported on NFS.
Since 5.x i've sometimes, when i read/write files and nfs-shares on heavy load, permissions will be changed that i can't connect anymore. Can see a little lock at the folders. After that i must restart the NFS-Server and remount the shares (on every client). I've tested it also with NFS4.

It is enough if I i set the permission from a folder to: example:
Code:
rwxrwx--- root docs /v-machines/testfolder
I'am member of the group "docs". And everything is working fine. But if nfs is on heavy load, after some copy the access would be denied. Rights are not changed.

It is not depending on ACL's, or export or mountoption. I've changed everything to defaults and deactivte all acl's. Also created new folder and data's. On every test the same result.

Has anyone ever observed such a behavior? I would no export it from a container or a vm.

Thanks a lot!
