Public bug reported: When you use the same resource for 2 minors, it crashes the kernel. Of course you should not do that, though I think it should not crash the kernel. The expected output is just an error message. This makes DRBD resource/minor management more difficult and also kind of dangerous.
DRBD 8.3 does not have this problem, probably because it works a bit different with resources/minors. Steps to reproduce: * drbdsetup new-resource test1 * drbdsetup new-minor test1 1 0 * drbdsetup new-minor test1 3 0 It exits showing the message 'Killed'. The kernel log shows some errors and DRBD is not usable anymore. After a short while or when executing other drbdsetup commands, the whole system crashes. I am not sure whether it's the utils package, or the kernel module.
