Hi, I have the following problem: I have a VG which sits on two partitions. This VG has been created with SuSE 7.2, that is version 1 of LVM. (I don't know exactly which one.) I wish to extend that VG and I have tried to do that from SuSE 9.2, which runs LVM version: 2.00.25 (2004-09-29) Library version: 1.00.19-ioctl (2004-07-03) Driver version: 4.1.0 The type of the partition is set to Linux LVM, like the others, but it does not work. I get this error: # pvcreate -vv /dev/hdg9 Setting global/locking_type to 1 Setting global/locking_dir to /var/lock/lvm File-based locking enabled. Locking /var/lock/lvm/P_orphans WB Getting size of /dev/hdg9 metadata/pvmetadatasize not found in config: defaulting to 255 metadata/pvmetadatacopies not found in config: defaulting to 1 /dev/hdg9: Couldn't find device. Check your filters? Unlocking /var/lock/lvm/P_orphans I can't see that the filters are a problem. The entry in /etc/lvm/lvm.conf is: filter = [ "r|/dev/.*/by-path/.*|", "r|/dev/.*/by-id/.*|", "a/.*/" ] I understand now that I should use -M1 to add this PV to an old V1 VG, but that is not the problem. I still get the same error. What am I doing wrong? Any help would be appreciated.
