Dear Roger,
I'm sorry to bother you with this, but I honestly don't know whom else
to ask regarding an LVM problem that I'm having. I've subscribed to
the LVM list, confirmed my email address, posted twice, but the email
doesn't get through. I've also email the list administrator about the
problem, and he has not replied to my email either. Maybe they are
blocking all googlemail account? Not sure.

But I've thought that maybe you could post it for me (just got a post
from you today so I've thought why not ask...)
If you don't feel comfortable don't worry, I'd understand. But if you
don't mind, I'll really appreciate. I haven't found a reference to
this issue anywhere else so it's one of my last hopes.
Thanks a lot,
-Jose

I'm having some strange error with lvm2.
During booting, a pvscan, lvscan, or pretty much any lvm2 command I
get the message "Unrecognised segment type mirror".

My system still works (I hope fine), but I don't like this messages
and I'm not sure what the cause is or whether it could cause
corruption. Anyone has a clue?
The following lines show the console output

vg0 is running on top of a software RAID-0 device combining two disks.
Vg1 is a concatenation of LVM partitions on the first disk, and vg2 is
a concatenation of LVM partions on the second disk.

thanks
