Hi,
I am new to LVM2, it is quite possible that I missed some steps.
I created an lv using the command:
dd if=/dev/zero of=/dev/sde bs=1k count=1
blockdev --rereadpt /dev/sde
pvcreate -v /dev/sde
... repeat for 27 disks
vgcreate v_db /dev/sde/ /dev/sdf /dev/sde ... 27 disks
lvcreate -i27 -I512 -L 100G -n lv_dbt3 v_db
The first time everything is fine.
To test another linux kernel, I re-imaged the whole system and
rebooted. But when I try to create lv, it complains
Couldn't find device with uuid ...
pvdata -p /dev/sde
--- NEW Physical volume ---
PV Name /dev/sde
VG Name
PV Size 0 [0 secs]
PV# 0
PV Status NOT available
Allocatable NO
Cur LV 0
PE Size (KByte) 0
Total PE 0
Free PE 0
Allocated PE 0
PV UUID none
lvmdiskscan shows:
/dev/sde [ 16.95 GB] LVM physical volume
Do I have to remove the lv and vg before I re-image the system?
What can I do now?
TIA,
Jenny
