[linux-lvm] Using lvm1 vg's in lvm2 systems (RHEL4)

[linux-lvm] Using lvm1 vg's in lvm2 systems (RHEL4)

Hi everybody,

  My production data is in RHEL3 system, using lvm1. I'll backup data
using business
continuous copy (BCV) from my production vg to a backup server with RHEL 4.
Is it possible to my RHEL4 system use these lvm1 vgs without converting it ?
What is necessary ?

Regards,

Fabricio

Yes, provided you can manage without snapshots and pvmove.
[Alternatively, you can run vgconvert to update your metadata in-situ to the
new lvm2 format.]

Alasdair,

  Thanks for your helping.

  I got these messages when I just execute vgdisplay, vgscan or pvscan:

  LV lv_oracle_data012: inconsistent LE count 252 != 1008
  Internal error: LV segments corrupted in lv_oracle_data012.
  LV lv_oracle_redo003: inconsistent LE count 4 != 16
  Internal error: LV segments corrupted in lv_oracle_redo003.
  LV lv_oracle_data020: inconsistent LE count 252 != 1008
  Internal error: LV segments corrupted in lv_oracle_data020.

  I just imported these volumes in another RHEL3 server without problems.

Any ideas ?

Regards,

Fabricio

Hi all.

   I've solved this problem downgrading the lvm version from RHEL4U2 to
RHEL4U1 included version.

Thanks all.

Thanks for indicating your solution.  I was having a very similar problem upgrading a Debian Unstable system a few months ago.  I still need to upgrade that system, so this might help me when that time comes around.
