Expand root directory on primary Drive

[vbbob]

I recently had to perform a clean install of v2.5 on my two-disk VB (120GB SSD and 8TB spinning storage drive, Plus an 8TB USB BACKUP disk).

My /storage is fine, but How can I expand the system root drive to the total 111GB available?

I followed the instructions,
https://wiki.vortexbox.org/vortexbox...n_instructions
But replaced
config_4-30.sh with: config_4-fill.sh

but my main drive still has a partition size of 7.2GB
fdisk -l

Download GPARTED - https://gparted.org/liveusb.php - and put it on a USB and boot from it. While you are re-sizing partitions you may want to increase the size of Linux swap.

[vbbob]

Thank you, that worked!
And it fixed my associated PLEX error: "The disk is almost full (less than 10GB remaining)"

One additional question: Even though I tried it first, I was not allowed to increase the size of the SWAP. Any ideas?

[Wirrunna]

Glad you got it to work, always good to hear back.

If you have expanded sda4 to the maximum, you could shrink sda4 by, say, 4GB by leaving 4GB in front of sda4 then after applying the change there will be an unallocated space which you can expand sda3 into.

[vbbob]

I actually tried setting the SWAP (sda3) first, but it would not let me make it larger, only smaller.
Also as I set sda4, I reserved a few Gigs, but it still would not let me change sda3 afterward.
When I check phpSysInfo, I don't see any usage, but maybe it happens too quickly?

I queried Andrew about the small swap space a while ago and he said that if you have more than 2GB RAM you shouldn't need to increase it. These days I build servers with 4GB RAM and set the swap at 4GB.
I have seen some of the swap space used by LMS on rescan, but I have 150,000 + tracks, MusicIP and InguzEQ running plus 4GB of video for Plex.

As an old systems guy, in the 1970's I was configuring IBM 360's for Virtual Storage and it is ingrained to have adequate swap space.

[agillis]

use the command config_4-fill.sh to fill the drive. That's all you need to do.

Don't mess with the swap space. it's not needed. I'll probable eliminate it in future releases.

[vbbob]

FYI, As above, I tried the config_4-fill.sh command, multiple times, but it never worked in THIS iteration.

GPARTED worked for me for me to expand sda4 and I left sda3 alone as it would not let me change it!

Thanks

I used "parted" to enlarge the /dev/sda4 partition to the full size of the drive... then for hours tried copying to the "/storage" folder only to be told I was full after only 3 gigabytes.

The secret that the effing internet doesn't really want you to know is you also have to use "resize2fs /dev/sda4" on the command line to make the file system expand to use the partition. Argh. So annoying to not just have these things stated along side the command to expand the partition. Screw you, internet! :-) but also thank you internet "Ask Ubuntu" forums for the answer.
