[PVE-User] drbd network interfacename

[Julian D. Seifert]

Content of my 70-persistent-net.rules is:

# PCI device 0x8086:0x10c9 (igb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:25:90:1d:30:93", ATTR{dev_id}=="0x0",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# PCI device 0x8086:0x105e (e1000e)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:1b:21:7b:4d:2c", ATTR{dev_id}=="0x0",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"

# PCI device 0x8086:0x10c9 (igb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:25:90:1d:30:92", ATTR{dev_id}=="0x0",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x105e (e1000e)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:1b:21:7b:4d:2d", ATTR{dev_id}=="0x0",
ATTR{type}=="1", KERNEL=="eth*", NAME="drbdlink"


And of 65-drbd.rules:
KERNEL=="drbd*", IMPORT{program}="/sbin/drbdadm sh-udev minor-%m",
NAME="$env{DEVICE}", SYMLINK="drbd/by-res/$env{RESOURCE}
drbd/by-disk/$env{DISK}"


Does THIS rule maybe match on drbdlink (after udev renames the network
interface according to our udev rule to drbdlink)? And then rename it to
drbd0? (To what does NAME="$env{DEVICE}" that evaluate?)
I didn't think this would apply as drbd deals with block devices)
