-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi,
first of all, I raised the severity of the bug to critical as it makes the whole system break. Also I add debian-devel to Cc as the bug is very problematic and I wonder how lvm2 was able to get into lenny with that big problem! Also I am willing to help solving the bug. My next step will be to import the whole version history to git and try to besect the problem. First to my use of LVM. I did use lvm1 with kernel 2.4 on etch for long time now using exact the same procedure which trigger the problem right now. Then with the release of lenny I start upgrading my stable systems. This involved a kernel upgrade as lenny only runs with the very instable kernel tree 2.6 and upgrade of the lvm metadata. A short test of the lvm snapshoots afterwards runs fine so I was not care about this road works (Is that the correct expression for the German "Baustelle"?). (I use snapshots every night in a script to backup the system.) Days after I noticed that apt-get install froze randomly and I had to reboot the system with a power cycle (reboot didn't work). First I was thinking about one of the many kernel bugs in 2.6 and tried the newest kernel from kernel.org. But the bug was still there. After several days I end in finding the problem in the LVM2 subsystem and two days later, today, I found this ug report and was very shocked! If I had know of it before I had never upgrade any of may stable systems to lenny! But now one of them is sticked on lenny as I know no way to revert the LVM back to LVM1. So this bug is a complete show stopper for lenny!!!! Am Sa den 14.

That is the correct description. But more over the system will be unbootable at all! I have to run /etc/init.d/reboot stop by hand to hard reboot the system. A normal shutdown will end in a hanging system with no remote access at all. The only solution at that point is to powercycle the machine which is very problematic with remote system. Am Fr den 2.

This is not really a problem as it is irrelevant if that file is locked or not in the sapshoot. Also the problem happens with random lvms not only with /var. And I wonder why this should be a problem at all as the lvm1 was working pretty stable for years now. Am So den 30.
