[pve-devel] debian11 ifslave bonding bug (with ifupdown1)

[alexandre derumier]

Hi,
multiple users have reported problems if ifenslave (ifupdown1),
(maintly upgrade from proxmox6 without switch to ifupdown2)


when physical interfaces have "auto .."

auto eth0
iface eth0
 ...
auto eth1
iface eth1 
  ....

auto bond0
  iface bond0
  bond-slaves eth0 eth1


it seem to come from a bug in ifenslave pre-up script
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968368
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=990428

patch here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?att=2;bug=968368;filename=ifenslave-args.diff;msg=5


Maybe it could be great to add a note in the upgrade procedure about
this until it's fixed. (or maybe provide a fixed proxmox ifenslave
package)

Regards,

Aleandre
