at the moment I preparing to RHCSA exam and complete some tasks to achieve desired result. I have a question by this task:"Create a logical volume called linuxadm of size equal to 10 LEs in vgtest volume group (create vgtest with PE size 32MB) with mount point /mnt/linuxadm and xfs file system structures. Create a file called linuxadmfile in the mount point. Set the file system to automatically mount at each system reboot."
In this task I don't understand what does it mean "LEs", I tried to google this information and i found nothing
LE means logical extent.
From lvcreate man page:
lvcreate creates a new LV in a VG. For standard LVs, this requires allocating logical extents from the VG's free physical extents. If there is not enough free space, the VG can be extended with other PVs (vgextend(8)), or existing LVs can be reduced or removed (lvremove(8), lvreduce(8).)
