Public bug reported:
Context: deploying nodes via maas with bonds and vlans
on top of them, in particular for the example below:
bong-stg and bond-stg.600
~# dpkg-query -W vlan
vlan 1.9-3.2ubuntu1.16.04.1
* /etc/network/interfaces excerpt as setup by Maas
(obfuscated for ip and mac addresses)
[...]
auto bond-stg
iface bond-stg inet static
address x.x.x.x/x
bond-xmit_hash_policy layer2
bond-slaves none
hwaddress ether xx:xx:xx:xx:xx:xx
bond-miimon 100
bond-lacp_rate slow
mtu 9000
bond-mode 802.3ad
[...]
auto bond-stg.600
iface bond-stg.600 inet static
address x.x.x.x/x
vlan_id 600
vlan-raw-device bond-stg
mtu 9000
* FYI bong-stg is properly brought up
* upping bong-stg.600 fails with:
~# ifup bond-stg.600
/etc/network/if-pre-up.d/mtuipv6: line 9: /sys/class/net/bond-stg.600/mtu: No
such file or directory
/etc/network/if-pre-up.d/mtuipv6: line 10:
/proc/sys/net/ipv6/conf/bond-stg.600/mtu: No such file or directory
Set name-type for VLAN subsystem. Should be visible in /proc/net/vlan/config
iface bond-mgmt inet manual
cat: /sys/class/net/bond-stg.600/mtu: No such file or directory
Device "bond-stg.600" does not exist.
bond-stg.600 does not exist, unable to create bond-stg.600
run-parts: /etc/network/if-pre-up.d/vlan exited with return code 1
Failed to bring up bond-stg.600.
- this happens because /etc/network/if-pre-up.d/vlan
hardcodes bond names to be bond[0-9][0-9]*
* changing above regexp to bond[^.]* fixes it
(modulo the mtu error):
~# ifup bond-stg.600
/etc/network/if-pre-up.d/mtuipv6: line 9: /sys/class/net/bond-stg.600/mtu: No
such file or directory
/etc/network/if-pre-up.d/mtuipv6: line 10:
/proc/sys/net/ipv6/conf/bond-stg.600/mtu: No such file or directory
Set name-type for VLAN subsystem. Should be visible in /proc/net/vlan/config
Added VLAN with VID == 600 to IF -:bond-stg:-
