PARTITION MAGIC VOLUME MANAGER HOW TO

dev/sda5 ubuntu lvm2 a- 698.04g 150g zzz ttt swap 0 linear /dev/sda5:yyy-www dev/sda5 ubuntu lvm2 a- 698.04g 150g xxx sss 0 free This will show the output like: /dev/sda5 ubuntu lvm2 a- 698.04g 150g 0 xxx root 0 linear /dev/sda:0-rrr So, initially, you need to check physical volumes' information using the command below: sudo pvs -v -segments /dev/sda5 That means after root and swap_1 partition. Then, you have to rearrange the unallocated space at the end of the LVM. If the second command produces something like this: /dev/sda5: cannot resize to xxxxx extents as later ones are allocated. Sudo pvresize -setphysicalvolumesize /dev/sda5 These are all the steps required to resize a LVM or LVM2 partition: sudo lvresize -verbose -resizefs -L -150G /dev/mapper/ubuntu

Sometimes, it wants you to unmount the partition that already mounted on / (in this case, you cannot unmount it). Note: You should run almost all of the following commands using a Live CD.

See How to shrink Ubuntu LVM logical and physical volumes? for help on that situation. Note: vgreduce will fail with cannot resize to xxxxx extents as later ones are allocated if you have another lv at the end of the disk - I had a swap lv, which I deleted. (optional) Remove a physical drive from the volume group if desired (if you now have an unused drive). (Note lvreduce parameter -L interprets G as 2^30 bytes and g as 10^9 bytes.) sudo lvreduce -resizefs -L 9G /dev/vg_blah/lv_blah Doing this in one step can avoid mistakes which cause dataloss. Resize the file system and the logical volume. sudo umount /dev/vg_blah/lv_blahĬheck the file system. This forum thread suggests the following procedure, in this example we shrink a partition from 10G to 9G:įirst, we unmount. Always assume that you can lose all your data when resizing partitions. Back up all your important data before attempting this.
