Good day all,
On lucid 10.04 client, with debian (sid) nfs server, using nfsv4, the client machine locks up/hangs on transfer of large files ~GiB+ to the nfs mount.
I am not alone, this was reported by:
Same behaviour with cp or nautilus.
No problems with scp, rsync, samba(except its super slow - no not an option)
Read from the server seems ok.
With the mouse free to move and everything else stuck I thought this could be the nic module or interrupts or something. Loading the module with debug enabled showed nothing.
The client machine is Dell XPS M1710 with:
Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet adaptor.
(so using wired in case you ask), standard mtu, connecting through a fast ethernet switch to via epia-en server, nic:
VIA Technologies, Inc. VT6120/VT6121/VT6122 Gigabit Ethernet Adapter
NFS is mounted as (from fstab)
and exported as (/etc/exports)
192.168.1.9: /media/minihaha nfs4 noauto,users,rw,hard,intr 0 0
Given the range of machines that this is occuring on, I doubt it is one nic. It may be a gigabit thing...
Can we amass the user experience here and see if there are any common factors.
Other than that, what commands etc. can I do to really log what is going on to try and determine what is causing this.
The weird thing is it doesnt happen straight away, it takes a finite (~40s) ammount of time, which I assume is why noone notices for small files. So there could be a buffer or somthing that get full...
Anyway, help and collaboration would be appreciated.
