Incorrect free space when using LVM RAID

  1. Add two 1 TB PVs to a new VG. Add one LV of 1 TB of type RAID1 to that VG. You now have two identical disks and have consumed all available space in that VG.
  2. Open blivet-gui and select your VG.

Logical View will display one LV of 1 TB and incorrectly show 1 TB of “free space”.

You can create new LVs in that free space. I’ve not tested what happens if you attempt that.

This is actually bug in LVM -- https://bugzilla.redhat.com/show_bug.cgi?id=1608930
But we also have another issue in blivet that made the LVM bug worse (storaged-project/blivet#709)

The blivet issue was fixed a long time ago so this should be also fixed in blivet-gui now.
