RHEL7.2 installer always has unused PEs in LVM even if
--grow
option is specified in kickstart or auto partitioning in GUI is selected.Sample output:
[root@localhost ~]# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert root rhel -wi-ao---- 17.47g swap rhel -wi-ao---- 2.00g [root@localhost ~]# vgdisplay --- Volume group --- VG Name rhel System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 3 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 19.51 GiB PE Size 4.00 MiB Total PE 4994 Alloc PE / Size 4984 / 19.47 GiB Free PE / Size 10 / 40.00 MiB <-- HERE
And the number of unused PEs is always 5 times of the count of existing LVs in VG.
On the other hand, installer in RHEL7.3 or later doesn't cause this issue.
