Subject: Xen 3.4.2 kernel / lvcreate crash
Date: Thu, 01 Apr 2010 03:34:15 +0300 [thread overview]
Message-ID: <4BB3EA07.5060807@dataproof.fi> (raw)
Hi,
I am using Xen 3.4.2 with kernel 2.6.18.8 and Debian Lenny. I am having
some problems with LVM-snapshots. I have crontab which makes once a
night a snapshot from domU's LV.
The problem is that maybe once in a month the lvcreate command stucks
and after that I have to reboot the machine to solve the problem.
So is this a problem on the Xen kernel or with Debian?
dmesg shows the following:
