VM Disk Full - 50 GiB in 4 months

[JohnGalt]

@sdetweil – OK, well… The program DID install (I was surprised , given what has been happening…). This resulted in an error. I specified that large file we identified earlier. Do let me know if I did the wrong thing. See results below.

While you are looking at this, I am going to fire up the other, older VM that also crashed and see if there is similar evidence there that might shed light.

@JohnGalt you need sudo in front of the mini dump. Line cause the file is in the /var folder

[JohnGalt]

@sdetweil – Yes, I did.

The output I pasted included 2 runs. The first returned an access error as expected. The 2nd run says ‘not a minidump file’.

I guess I confused things by pasting all that. Sorry.

[sdetweil]

@JohnGalt no problem… thx… I have not tried to examine them myself either

[sdetweil]

@JohnGalt there is a new script in my package , cleanup.sh

intended to erase all the electron binary downloads and
any npm cache

[JohnGalt]

@sdetweil – Thanks, Sam.

When I get back from my travels next week I hope to have time to look at this.

IIRC, my primary stumbling block is how full the disk is, meaning I don’t recall if the machine even still boots. I hope it still has room to boot and load the script! That would be great.

[sdetweil]

@JohnGalt if you have a usb carrier for the sd card, you could make and boot another one and mount the old one to erase the files

[JohnGalt]

@sdetweil – Just as a reminder, this is an instance of Magic Mirror installed on Linux in a Virtual Machine, running under TrueNAS Scale.

I just confirmed that the VM will start and run and I can SSH into it from my desktop. As such, I should be able to upload the script.

Query: Do we expect the script to run as intended under a VM?

[sdetweil]

@JohnGalt it should under a VM… under a docker container no

[JohnGalt]

@sdetweil OK, I was able to run the script on 2 different VMs where MagicMirror is failing to run. In both cases, it still doesn’t run. Th script reported substantially more space available after running, but MagicMirror still doesn’t run. While I am approaching the point where it will be more efficient of my time and yours to just create a 3rd VM, I will post the output of pm2 status below, in case it happens to shed any light on the subject:
