Hi,
Network block device appears to be blocked when I copy the many
files on exported filesystem. Like this.
./nbd-client cosmo 3000 /dev/nb0 &
mount -t ext2 /dev/nb0 /mnt
cd mnt
ls
/manyfilesdir lost+found/
cp -r manyfilesdir .
< -- blocked. prompt never returns -->
This is occured in both 2.2.14 and 2.3.9pre-6 kernels.
Although, it failed, I found that it sucess to copy many files in
local to exported filesystem vise versa.
The following is a result of netstat when blocking is occured.
