So what is your disk’s capacity?
x61:~% sudo pvscan
PV /dev/sda5 VG x61 lvm2 [111.55 GB / 0 free]
Total: 1 [111.55 GB] / in use: 1 [111.55 GB] / in no VG: 0 [0 ]
Not sure wtf is on sda1
x61:~% cat /proc/partitions
major minor #blocks name
8 0 117220824 sda
8 1 248976 sda1
8 2 1 sda2
8 5 116969233 sda5
254 0 7000064 dm-0
254 1 2719744 dm-1
254 2 107245568 dm-2
7 0 102400 loop0
254 3 101372 dm-3
8 16 2015232 sdb
8 17 184716 sdb1
To find out about your logical volumes:
x61:~% sudo lvscan
ACTIVE '/dev/x61/root' [6.68 GB] inherit
ACTIVE '/dev/x61/swap_1' [2.59 GB] inherit
ACTIVE '/dev/x61/home' [102.28 GB] inherit
Remember in order to reduce say home, you first need to resize2fs
home down and then you can think about sudo lvreduce -L-10g /dev/x61/home
.
