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 ?

# mount | grep ' / '
/dev/md0 on / type ext3 (rw,errors=remount-ro)
# fdisk -l

Disk /dev/sdb: 250.1 GB, 250059350016 bytes
...
   Device Boot      Start         End      Blocks   Id  System

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