question on lvcreate
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:
[email protected] ~]# 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:
[[email protected] ~]# 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?
