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'.
Device /dev/sdb not found (or ignored by filtering).
================
pvcreate -ff -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'.
Device /dev/sdb not found (or ignored by filtering).
================
vgreduce -t --removemissing VolGroup01
Test mode: Metadata will NOT be updated.
Couldn't find device with uuid
'qf0ApW-42u1-nlyq-2TTn-MIgB-3dT1-BNe3GF'.
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?
