Hello,
My hosting provider has a setup for me a Debian server using md RAID1 but it
does not use LVM, should I consider re-install with LVM ?

Of course not. If you wanted LVM you'd switch to it. If you don't know
if you want it, then obviously you don't need it.

Hello,
Have a look at the command output : "Disk /dev/md0 doesn't contain a valid
partition table"
Is it safe to ignore this warning ?

Sorry for the rude response,
AFAIK you'll see that "warning" if you use LVM (I see it in my setup),
as LVM isn't a file system per se.

I've a feeling that message appears with any kernel that supports
general partitionable devices if the device isn't partitioned, e.g. you
put a filesystem on your md device. If /dev/md0 isn't meant to be
partitioned, it's harmless.
Cheers,
John.

maybe, you will use snapshot? ext3 don´t have snapshot, will you use lvm?
