sorry for cross-posting with fedora mlists. after pvcreate /dev/sdc Physical volume "/dev/sdc" successfully created sadly i issued: vgextend /dev/mapper/VolGroup01 /dev/sdc Volume group "VolGroup01" successfully extended instead of doing: vgextend VolGroup01 /dev/sdc Volume group "VolGroup01" successfully extended I used the wrong syntax. then i tryied to extend lv lvextend -l 100%VG /dev/mapper/VolGroup01-lvol0 Couldn't find device with uuid 'qf0ApW-42u1-nlyq-2TTn-MIgB-3dT1-BNe3GF'. Extending logical volume lvol0 to 329,99 GB Cannot update volume group VolGroup01 while physical volumes are missing. now i tried to assign that uuid to /dev/sdb, sadly w/out success: ================ pvcreate -u qf0ApW-42u1-nlyq-2TTn-MIgB-3dT1-BNe3GF --restorefile /etc/lvm/archive/VolGroup01_00002.vg /dev/sdb Couldn't find device with uuid 'qf0ApW-42u1-nlyq-2TTn-MIgB-3dT1-BNe3GF'.

WARNING: Partial LV lvol0 needs to be repaired or removed. WARNING: There are still partial LVs in VG VolGroup01. To remove them unconditionally use: vgreduce --removemissing --force. Proceeding to remove empty missing PVs. ================ is there a clean solution to my fault? tia Maurizio _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
