When a samba server shares NFS4 mount directory, window clients cannot copy file. ERROR: 0x80070021
The error reported by windows client is like this ERROR: 0x80070021 The process cannot access the file because another process has locked a portion of the file.
I google it and hit samba bug report 8481 . Which is very similar to this problem. Another link also mentions a similar issue.
But, instead of NFSv3, my NFS backend is using NFSv4, provided by OpenSolaris ZFS file system.
I try to mount -t nfs4 -o nolock fileserver:/export/home /home
, but it says no such option "nolock"
. nolock
is only valid for NFSv3, not NFSv4.
- fileserver: an OpenSolaris file server.
- Linux server: Debian Lenny. Running
samba
service and mount/home
tofileserver:/export/home
- Windows client: it can browse the directories shared by the linux server, but cannot copy any files.
From what I found googling, this is a problem caused on NFS level, to fix it edit /etc/samba/smb.cfg
and in the [global]
section add the option:
strict locking = no
