[Users] same nfs mount dir in VEs

[Yoann Moulin]

Hi,

I have a problem with nfs mount in different VEs

for example, I have inside some VEs :

$ df /mnt/data
10.0.0.1:/nfs/data   134148096  43458560  90689536  33% /mnt/data

if I perform a reboot on one VE, on all others VEs where this partition is mounted, I got :

$ df /mnt/data
10.0.0.1:/nfs/data      -         -         -   -  /mnt/data

so the partition is still mount but impossible to do an access on.

at the same time I got this in kernel log on the host :

[258012.479557] unregister_vlan_device: ERROR:  Tried to remove a non-vlan device with VLAN code, name: eth1.35  priv_flags: 0
[258012.646468] unregister_vlan_device: ERROR:  Tried to remove a non-vlan device with VLAN code, name: eth1.32  priv_flags: 0
[258013.466439] nfs: RPC call returned error 101
[258013.711497] nfs: RPC call returned error 101
[258013.715907] nfs: RPC call returned error 101

As soon as I removed all references of that mount point in all VEs. I can remount it, it's working.

VE 201 :
NETIF="ifname=eth1.32,mac=00:16:3E:02:01:1E,host_ifname=veth201.32,host_mac=FE:FF:FF:FF:FF:FF;ifname=eth1.35,mac=00:16:3E:02:01:1E,host_ifname=veth201.35,host_mac=FE:FF:FF:FF:FF:FF;ifname=eth1.36,mac=00:16:3E:02:01:1E,host_ifname=veth201.36,host_mac=FE:FF:FF:FF:FF:FF"NETIF="ifname=eth1.32,mac=00:16:3E:02:02:1E,host_ifname=veth202.32,host_mac=FE:FF:FF:FF:FF:FF;ifname=eth1.35,mac=00:16:3E:02:02:1E,host_ifname=veth202.35,host_mac=FE:FF:FF:FF:FF:FF;ifname=eth1.36,mac=00:16:3E:02:02:1E,host_ifname=veth202.36,host_mac=FE:FF:FF:FF:FF:FF"
