Hello,
I 've been unsuccessfully trying to move data from the existing VG to a new VG.
Here are the steps i did:
[code]

the drive i'm trying to move the data to is /dev/sdb. Dived into 2 partitions. Each 500Gb.
The "/dev/VG_Storage01/LV_VG_STORAGE01" is the original LG that had 2 drives (partitions) -
step by step:
0. /dev/VG_Storage01/LV_VG_STORAGE01 of is not mounted;
1. /dev/VG_Storage01 originally had /dev/hdc2 and /dev/hdd2.
2. I added /dev/sdb1 into /dev/VG_Storage01
3. did pvmove /dev/hdc2 /dev/sdb1 and pvmove /dev/hdd2 /dev/sdb1
4. removed /dev/hdc2 and /dev/hdd2 from /dev/VG_Storage01
5. created VG_Storage with /dev/hdc2 and /dev/hdd2
6. tried to extend /dev/VG_Storage01/LV_VG_STORAGE01:
[code]
vextend -l +100%PVS -r -t /dev/VG_Storage01/LV_VG_STORAGE01
Test mode: Metadata will NOT be updated.
Segmentation fault
lvextend -v -l +100%FREE -r -t /dev/VG_Storage01/LV_VG_STORAGE01
Test mode: Metadata will NOT be updated.
Finding volume group VG_Storage01

Thank you for your help.
