[Bug 744293] Re: Infinite loop in helper LVM script for DRBD 8 in Lucid

[Jacob Smith]

Hi Andres,

So I gave it a try and now I'm racking my brain because I thought I knew
what I was doing but it didn't behave as I expected and I don't know if
it's my ignorance or a problem so I'll let you be the judge!

Executed the following on both nodes, one after the other finished:
Added your PPA.
apt-get update; apt-get upgrade
Edit /etc/drbd.d/global_common.conf and uncomment before and after-resync-target
shutdown -r now

Ended up with all kinds of errors and zombie lvm processes and drbd complaining etc. after restart.
Looked at the lvm scripts in question - /usr/lib/drbd/snapshot-resync-target-lvm.sh
The changes from the patch are not there... if I understand what the patch was supposed to do.
First - The meat of the patch was to remove a couple of "shift" lines from the case statement among other things correct?
Second - doing the apt-get upgrade should have replaced the patched script?
