OL 8.3 , a vm under VBox
After initial creation of the vm and installtion of OL 8.3, I added a second 'disk', and wish to create a lvol on it.
The disk was sized at 12g. I got the disk partitioned (one single partition) and created a vgroup with it, yielding this:
root@vbol83-02 ~]# vgdisplay vg_u01
--- Volume group ---
VG Name vg_u01
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 1
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 0
Open LV 0
Max PV 0
Cur PV 1
Act PV 1
VG Size <12.00 GiB
PE Size 4.00 MiB
Total PE 3071
Alloc PE / Size 0 / 0
Free PE / Size 3071 / <12.00 GiB
VG UUID c93T67-gZXF-CMSW-1b7u-3ZBt-x3P3-F9dIGP
Now, when I try to create the lvol, I get this:
[root@vbol83-02 ~]# lvcreate --size 12G vg_u01
Volume group "vg_u01" has insufficient free space (3071 extents): 3072 required.
So what should I be applying for the size? How does the math work out on this?
