vgcreate problem

try checking with pvscan

or try using /dev/evms/sda1

Thx, but finish learning lvm2, not evms!

root@299903:~# vgcreate teszt /dev/sda1
  No physical volume label read from /dev/sda1

try using /dev/mapper/sda1 instead of /dev/sda1 in the vgcreate.

Also can you show us this info from you system? (i'm showing mine a 7.04
system with lvm2)

sudo vgcreate --version

Thanks the reply my problem!

My ad hoc idea: dd if=/dev/zero of=/dev/sda1 bs=1024 count=1000

Probing reboot...

That's pretty cool, so maybe some old or previous bits at the superblock were
overlapping the lvm2 data....

glad that you could solve it.

Andres

The problem selved!
