Disk space issue

[gmartin]

I'm running 25.1.12 in a VM on proxmox v9. It's been running about 9 months without issue.  I noticed today the drive was full.  In the proxmox console, I increased the disk space to 50GB.  I was prompted in the console to run a command to accept the growth but it did not expand the file system. 
The system is showing a discrepancy between gpart and df.

I assume there is something I need to do inside to grow the fs, but growpart isn't available. Is there another tool?

(BTW, I deleted some logs to alleviate the immediate issue.)

Thanks!

Have a look at a similar thread from about a week ago: https://forum.opnsense.org/index.php?topic=50436.0, the post from Maurice.

But the instructions given there will not work for this specific setup, because the ufs partition is not the last one on the disk. The swap partition is in the way for the enlargement and has to be deleted first.

Good point @meyergru, I didn't notice that.

@gmartin but do not (!) just go ahead and remove the swap partition, then use the procedure outlined by @Maurice. This will lead to a system with no swap at all. Bad idea.

So from the top of my head without any guarantee it will work - go step by step and check the results before proceeding to the next one, please:

Code Select Expand

# make sure secondary GPT header is present
gpart recover da0

# disable swap - take note of the device name, e.g. "/dev/da0p4" or "/dev/gpt/swap"
swapoff -a

# remove swap partition
gpart delete -i 4 da0

# resize UFS partition
gpart resize -i 3 -s 36g da0

# recreate swap partiton - if the device in the first step was "/dev/da0p4" use this:
gpart add -i 4 -t freebsd-swap da0

# recreate swap partition - if the device in the first step was "/dev/gpt/SOMELABEL" use this:
gpart add -i 4 -t freebsd-swap -l SOMELABEL da0

# re-enable swap
swapon -a

If that worked you should have a system with 8 G of swap like before and a resized UFS partition. The last step is to resize the UFS proper.

Connect a console and reboot into single user mode. Do not mount the root partition read/write, just leave it read only (this is the normal state after entering single user mode).
