Readme: Write guide to resize guest fs #31

Open rodrigobdz opened 5 years ago

rodrigobdz commented 5 years ago

Add documentation on how-to resize guest filesystem to help users. There are a couple of additional steps involved after installing vagrant-disksize which are not straightforward.

noaho commented 5 years ago

These are the commands I used in my Vagrantfile for bento/ubuntu-18.04

#Extend Volume to take up free space
$resizescript = <<-SCRIPT
parted /dev/sda resizepart 1 100%
pvresize /dev/sda1
lvextend -r -l +100%FREE /dev/vagrant-vg/root
SCRIPT
config.vm.provision :shell, inline: $resizescript

Unfortunately these instructions don't seem to work RHEL-based systems such as Fedora.

@blissdev Did you get an error? Please attach anything which could be useful identifying the problem

I have a CentOS 7.7 box. The 8GB drive have been resized to 100GB using this plugin. I cannot figure out how to resize or even see the additional space. Could you recommend a solution?

@sprotheroe Could you review this PR?

clbarnes commented 3 years ago

For reference, this is also discussed in #37 . The snippet posted by @noaho has worked for me in the past but does not after bumping the ubuntu version of my box.

rodrigobdz commented 3 years ago

@clbarnes Thanks for linking the issue. Regarding the snippet, it probably doesn't work anymore because the device partition number (/dev/sda1) is different. Please verify.

Ideally, the device partition selection should be done automatically in the script.

clbarnes commented 3 years ago

I tried with ubuntu/bionic64 (same ubuntu version, just a different provider). I provisioned without a disk resize, then SSH'd in, but according to df, /dev/sda1 is still the only device partition number. fdisk --list reports a partition /dev/sda1 and a disk /dev/sdb (10MiB)

However, despite failing, df, fdisk, and lsblk do report the desired size rather than the default size. Does this suggest it may not need the pvresize/lvresize?

rodrigobdz commented 3 years ago

Hard to say but here's a checklist to verify correct resizing.

Verify actual size of:

clbarnes commented 3 years ago

It seems the way to look at logical volumes, physical volumes, and volume groups is through the (lv|pv|vg)(s|display|scan) commands. I get no output from any of them (as root), even with the --all flag. Is it possible LVM is just being sidestepped entirely?

I tried to fallocate a file larger than the original disk space, and it succeeded. Doing that with a file larger than the desired disk space (aka the disk space reported by df/fdisk/lsblk) failed. I would take this to mean that resizing volumes and partitions is not necessary with ubuntu/* boxes or recent bento/ubuntu-* boxes.
