Problem extending partition for hass.io on Ubuntu Server

flemmingss · August 3, 2018, 8:59pm

I have a Ubuntu Server VM running on my ESXi box for Home-Assistent (hass.io). And it has worked pretty well, until now. I am not able to update Home-Assistant due to low disc capasity. Since this is an VM i have changed the disc spance for the VM from 10GB to 24GB. But now I need to expand the partition, witch I have some problems with.

I have tried to follow this guide, but are stuck on “Extend your Logical Volume with the new partition” or maybe before

this is what I have done:

And this is what happen when I try to extend the volume:

So, do anyone have a solution for me?
I can say I am not a linux person, so in detail please.

I am thinking this is because there is no room between sda3 and sda2. You can’t expand a partition without some spare space.

flemmingss · August 4, 2018, 11:20am

But I have total of 24GB?

Boot up a live distro with a GUI and it will be much easier.

GParted, resize your partitions, and then run your LVM commands.

flemmingss · August 10, 2018, 8:52pm

Not a bad ide, I will try that

flemmingss · August 10, 2018, 9:49pm

any ide how I can unlock this?

when i right click i only got “manage flags” and “info”

also tried this in console:
wapoff -a
swapoff -a /dev/sda2
umount /dev/sda2

nickrout · August 10, 2018, 10:16pm

sda2 is an extended partition. sda5 is inside sda2. I think it is sda5 you need to deal with.

flemmingss · August 10, 2018, 11:20pm

Well, i left it to watch some youtube, and when I came back the locks was gone, so no its done

Well, but now i see that size may not be the couse for the update problems.
WARNING (MainThread) [hassio.host.services] Can’t update host service information!

flemmingss · August 12, 2018, 7:39am

Well well, looks like i was wrong, when I try apt-get update it say 28: No space left on device)…

Why don’t you try deleting some unneeded files ?

eg /var/cache/apt/archives is disposable, and often collects a lot of crap.

flemmingss · August 12, 2018, 8:22am

Well, now that I have resized the drive I might as well extend it to be used for somthing.

Also tried this:

flemmingss@Home-Assistant:~$ sudo resize2fs /dev/mapper/Home--Assistant--vg-root
resize2fs 1.42.13 (17-May-2015)
The filesystem is already 2293760 (4k) blocks long.  Nothing to do!

btw: are all files in that dir unneeded and safe to delete?

nickrout · August 12, 2018, 8:25am

Yes they are a cache of downloaded packages that have already been installed.

By the way, it is a long time since I used lvm, but when I did, I found I couldn’t find anything better than

flemmingss · August 24, 2018, 11:57am

Thanks for the link. But still not able to solve this.
But do anyone else have some suggestions?

flemmingss · August 26, 2018, 10:02pm

I fixed this problem by reinstalling ubuntu

flamingm0e · August 26, 2018, 10:23pm

Well that was overkill

flemmingss · August 27, 2018, 7:50am

Well, it was done in 40 minutes including install of Hass.io and backup/restore. Way less time then I have used to try to extend the partition until now.
