Try mounting with first nfs v3 and then nfs v4, see if it makes any difference?
Worth noting that NFS v4's uid mapping feature had a very, very long-standing bug on Linux that caused pretty odd behaviour in regard to permissions, but after years it was marked as fixed upstream last month. But it'll still be busted in wheezy and 3.11.
Thanks for the suggestion. I have upgraded the NFS clients in question to the 3.12 kernel from Debian/Unstable and that problem is fixed now. I'm using SATA-USB devices formatted as BTRFS for most of my backups which has compelled me to upgrade most systems to newer kernels than I usually run. So running a kernel from Unstable for NFS reasons isn't a big deal. The client system that was already working was running a 3.12 kernel, so my problem report was obviously lacking in that regard. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
