After upgrading to 2.6.18-028stab045 (nfsutils 1.1.0) i get the following when i try to umount a nfs filesystem in a VE: 
 
'nfs' is not a legal NFS export name 
 
 
:/# mount 
simfs on / type simfs (rw) 
tmpfs on /lib/init/rw type tmpfs (rw,nosuid) 
proc on /proc type proc (rw,nosuid,nodev,noexec) 
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec) 
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) 
devpts on /dev/pts type devpts (rw,nosuid,noexec) 
nfs on <dir> type nfs  (rw,noatime,nodiratime,vers=3,rsize=8192,wsize=8192,acregmin =60,acdirmin=60,soft,intr,proto=udp,timeo=600,retrans=2,sec= sys,addr=...) 
:/# umount <dir> 
umount.nfs: 'nfs' is not a legal NFS export name 
umount.nfs: 'nfs' is not a legal NFS export name 
 
 
:/# more /etc/mtab 
simfs / simfs rw 0 0 
tmpfs /lib/init/rw tmpfs rw,nosuid 0 0 
proc /proc proc rw,nosuid,nodev,noexec 0 0 
sysfs /sys sysfs rw,nosuid,nodev,noexec 0 0 
tmpfs /dev/shm tmpfs rw,nosuid,nodev 0 0 
devpts /dev/pts devpts rw,nosuid,noexec 0 0 
nfs <dir> nfs rw,noatime,nodiratime,vers=3,rsize=8192,wsize=8192, 
 acregmin=60,acdirmin=60,soft,intr,proto=udp,timeo=600,retran s=2,sec=sys,addr=... 0 0 
 
 
Also when I try to umount a VE with a nfs filesystem mounted in it the HW node hangs (like the old nfs umount bug). 
 
 
Any ideas? 
 
Thanks 
Alex
