vgscan problem: Snapshot and origin LVs must differ.

Hi Guys!

I tell you my LVM story....

I have add LVM1 capability to my linux box kernel 2.4.36.5.

So I make (whit success) a snapshot of my /dev/VOLHOME/HOMELV! Snapshot's name is SNAPHOME.

Than I restart my linux box.

Now I can't mount /dev/VOLHOME/HOMELV and "vgscan -v" write this messages:

:
:
/dev/sdb1: size is 3906204687 sectors
/dev/sdb1: lvm1 label detect
Locking /var/lock/lvm/V_VOLHOME RB
Finding volume group "VOLHOME"
/dev/sdb1: lvm1 label detected
Found /dev/sdb1 in VG VOLHOME
Snapshot and origin LVs must differ.
Couldn't add snapshot.
Found /dev/sdb1 in VG VOLHOME
Snapshot and origin LVs must differ.
Couldn't add snapshot.
Volume group "VOLHOME" not found
Unlocking /var/lock/lvm/V_VOLHOME

I don't know what's happen!

Help me please, thanks Alessandro

That's output from lvm2 - but you say your kernel only has lvm1 in it. You can't mix and match them like that: work out what you meant to run - lvm1 or lvm2.

Hi Alasdair!

I writed you log message show me by sysreccd 1.4beta7.

This sysresccd version is lvm1 capable.

I don't understand what means:

"Snapshot and origin LVs must differ." ?

Thanks, Alessandro
