/var is low on disk space

@azdeltawye said in /var is low on disk space:
I strongly agree with that advice. My SG-5100 exhibited this same behavior when I upgraded to 23.01 back in March. I installed a compatible SSD within a couple days but unfortunately it was too late. The eMMC had completely failed at that point and prevented the unit from booting.
Unfortunately for @azdeltawye, but (and I think I speak for both of us here) we hope to be fortune for others, this very same 5100 is the one I mentioned above where I extracted the eMMC from the board and it immediately started perform normally.
It's not a process I recommend everyone to do -- but for those who have the skills it can be done.
This is the eMMC on the board (the bottom side)
The board removed using a re-soldering station (a programmable heat gun)
The empty space (partially cleaned up)
The bottom of the eMMC.

My beloved SG-5100 was a boat anchor after only 20 months of use!
Indeed. I got 16 mo's out of my 1st 5100, this one is going on 27 mo.
Same as you, my biggest write-hvy is pfBlockerNG. I am also simple home w/4 active devices but up to 30 because of smart devices.I was thinking of getting a SSD just to have more room, I had no idea how fragile the SSD was until now. I knew it was limited but didn't think it was this limited. A few minutes ago I cut my pfBlocker updates from 4x/day to once.
Thanks

use a re-soldering station to heat the eMMC and remove it from the board.
Referring to the later post with the photos of the removed eMMC can you clarify for me:
If an mSATA is installed it will supersede the eMMC, essentially making it electronically 'disappear'?But if it goes south then the mSATA won't do any good?
That is what I understand from what you posted, correct?
And the 32 GB SATAIII M.2 2242 SSD would be a suitable replacement?
As an aside, my 1st 5100 is still laying around, but if I read correctly, adding a mSATA probably won't help because if the eMMC is the cause then it's too late. Correct?
Is this likely to be a similar situation with my old 2440 w/ 20GB drive? Or is that a totally different situation? I know this may be impossible to answer, just fishing on the off chance I can get a working emergency spare. I'm ok with soldering but I don't have a re-soldering station, just a solder sucker and copper braid. And noticeably shakier hands than in the 'good old days'.
Neither of those units will POST and the only signs of life is the power light.

Note NtopNG is marked "Requires SSD/HDD" in the linked package list above...
@rcoleman-netgate "...do not boot nor provide an output via the serial cable." Would that be similar for the 4860 model we discussed elsewhere? IIRC that doesn't have eMMC or at least can't use the "write life" software. Plus I'd expect the backup router to have way less disk writes.

When I purchased my first 5100 in Nov 2019, to replace my dead 2440 w/ 20gb drive, I asked about boosting the product above the 8gb because I did not feel it was enough. The sales person said 8 was enough and they didn't have any upgrades for 5100.
I don't know when the "marked "Requires SSD/HDD"" was posted but at that time I probably would not have seen it even if it was posted. I stopped using NtopNG about 6 mo's ago but would like to run it again.
That linked list also mentions DarkStat. I do run that.
Thanks for this info.

I am glad that my old 5100 has a chance at a second life.
I'm happy to help the cause!! -

Referring to the later post with the photos of the removed eMMC can you clarify for me:
If an mSATA is installed it will supersede the eMMC, essentially making it electronically 'disappear'?No. The BIOS POST has a step we haven't been able to find a way around -- a read-only eMMC will cause the system to boot very slowly (15-30 minutes to POST) or not at all.
And the 32 GB SATAIII M.2 2242 SSD would be a suitable replacement?
Probably.

If, yes. If this is the case, and you are in the United States, and you are interested in having it used for a testing/trial process LMK and I can open DMs for you.

The RED LED of death? That's a CPU issue on the C2000 systems. The 5100 is not a C2000.

The red LED of death is a C2K CPU issue. In theory you could use the same technique to replace the CPU but ... I am not about to do that experiment.
-
@rcoleman-netgate Hmm, no LED for me, just fan noise. Just curious. Never mind. :)

Hahaha. After replacing my wife's iPad battery I swore I'd never dive into these things again. And I didn't have to use my soldering iron for that one.
thanks
-
@SteveITS Then I don't know. I haven't had access to any of the C2K devices personally. You could give it a try if you have a reworking station.

Can you explain what you mean by this?
-
@JonH said in /var is low on disk space:

@stephenw10 and I have a theory that we might be able to bypass the POST check for the dead eMMC without removing the chip from the system -- which requires a reworking station to perform.
Finding 'dead' 5100s has been difficult. I've only so far gotten my hands on one (@azdeltawye's former unit) and it now sits on my desk as a testing unit.

Ryan:
OK, this sounds interesting to me, better than the landfill.
For my working 5100 I just ordered "Transcend 32GB SATA III 6GB/S MTS400S 42 mm M.2 SSD 400S Solid State Drive TS32GMTS400S" off of Amazon cause Sales said they no longer have any parts for 5100. I hope this is the correct drive.
The Netgate docs page on '5100 sata install' mentions "8. Locate the Thermal Pads that came with the SG-5100."
After all these years I cannot find the box (believe it or not, I usually keep them) so I have no thermal pads. Can you advise if they are necessary and on what I can look for in order to purchase? I asked Sales and they couldn't help me with that.
Finally, after requesting an image, how can I get pfSense loaded on the sata? I misplaced my notes on image install. Would this be via Etcher? I did this once before when I changed fs to zfs but I don't recall exactly what I did nor whether I used Etcher (I must have cause I have the app installed on my iMac). Will the sata boot first once it's installed?
I'll get back to you in a week or so on the dead 5100.

They (quite probably Ryan) will send you instructions with the file but they are also here:
https://docs.netgate.com/pfsense/en/latest/solutions/sg-5100/reinstall-pfsense.htmlPer the other page https://docs.netgate.com/pfsense/en/latest/solutions/sg-5100/m-2-sata-installation.html "By default, the M.2 SATA drive will be the first drive recognized..."
@rcoleman-netgate said in /var is low on disk space:

We don't. I just would have expected a BIOS screen level boot attempt so it caught my eye that the 5100 doesn't output anything if the storage dies. It's unlikely to be storage due to wear, since it was our backup router so probably has 1% of the usage of the main. We have replacements arriving today anyway.

Nope, just look into thermal pads that are 2 or 3mm in depth? I can check later tonight when I get back to my desk -- I'm working in the lab for a few hours.
For my working 5100 I just ordered "Transcend 32GB SATA III 6GB/S MTS400S 42 mm M.2 SSD 400S Solid State Drive TS32GMTS400S" off of Amazon cause Sales said they no longer have any parts for 5100. I hope this is the correct drive.
Correct, we used to have SSDs for sale to the public but that is no longer the case. If it's B-keyed, or B+M keyed you should be fine.

Thank you, I went ahead and ordered 2mm from Amazon. No need to check later.
FYI, I just submitted ticket on TAC-Lite for zfs image to install on the sata I just ordered. -
@JonH PfSense has a games folder, mine never did.
Make sure to upvote

@JonathanLee
That's where you place 'Doom for pfSense'. -
@JonathanLee That is one of several folders on my pfSense that is empty. It can sure lead to a lot of speculation tho. I like Gertjan’s answer.
