[linux-lvm] LVM Problems :)

Fri Feb 13 12:05:05 UTC 2004

Greetings again,

Curious, I replied, but did not recive a copy of my reply,
maybe it got lost in the internet? :) Killed by a rogue lvm,
I assume ;) - If this was/is only me missing my reply, then
I am deeply sorry for spamming - not intentionally, really.
