I have 3 RAID arrays in my server, mapped to 2 PVs in my lvm2 setup.
apollo:~# pvs PV VG Fmt Attr PSize PFree /dev/sda1 apollo lvm2 a- 3.64T 0 /dev/sda2 apollo lvm2 a- 1.14T 0 /dev/sdb apollo1 lvm2 a- 2.05T 0 apollo:~# lvs LV VG Attr LSize Origin Snap% Move Log Copy% lvol0 apollo -wi-ao 4.77T ling-ling apollo1 -wi-ao 895.41G lvol0 apollo1 -wi-ao 1.17T lvol1 apollo1 -wi-a- 32.00M
I want to remove the LV "ling-ling" to free up some space, however I want to expand lvol0 with that free space, which is residing on the other VG.
Is there a way in LVM to allocate a percentage of a PV to different VGs without repartitioning? The only solution I can think of is to repartition /dev/sdb but I would prefer not to, since this is a live server.
