How to add a home directory, add a new LVM volume, and expand the volume size on our linux home directory server 'moe'
Prerequisites
Secure Shell access to moe as the root userStep by step
Create a home directory on moe :
cd /volumes/<faculty member>/users/
mkdir <username>
chown <username> <username>
Create a new volume for a faculty member's users:
# 50G is the current 'default' volume size
lvcreate -L 50G -n <newfacultylastname> users
mkfs.xfs /dev/users/<newfacultylastname>
echo /volumes/<newfacultylastname> 10.0.0.0/8(rw,no_subtree_check) >> /etc/exports
echo /dev/users/<newfacultylastname> /volumes/<newfacultylastname> xfs defaults 0 0 >> /etc/fstab
mount /dev/users/<newfacultylasname>
Expand the size of a faculty member's volume
#Ensure adequate free space on the users' volume
#root@moe:~# vgs users
# VG #PV #LV #SN Attr VSize VFree
# users 1 12 0 wz--n- 1.79T 369.49G
# to add a certain amount of space
lvextend -L+50G /dev/users/<volume>
# to increase the volume to a specific size
lvextend -L200G /dev/users/<volume>
#finally one must grow the filesystem
