How to free internal storage on CRS326-24G-2S+

Sat Oct 20, 2018 3:40 pm

Hi,

I have several CRS326-24G-2S+ switches running RouterOS (now 6.43.4). They have 16MB internal storage and on all of them, that's almost full.

When I installed SSL certificates on one, it ran out of memory completely: free-hdd-space: 0

On others, memory is getting close to exhaustion:
/system resource print 
                   uptime: 48w2d5h12m42s
                  version: 6.40.5 (stable)
               build-time: Oct/31/2017 13:05:15
         factory-software: 6.38.2
              free-memory: 470.9MiB
             total-memory: 503.4MiB
                      cpu: ARMv7
                cpu-count: 1
            cpu-frequency: 800MHz
                 cpu-load: 0%
           free-hdd-space: 4340.0KiB
          total-hdd-space: 16.0MiB
  write-sect-since-reboot: 64552
         write-sect-total: 66432
               bad-blocks: 0%
        architecture-name: arm
               board-name: CRS326-24G-2S+
                 platform: MikroTik
The standard packages contain a lot of stuff I don't need, but I see no way to remove them (and I'm not sure it will matter that much).
When the memory was 100% full, configuration changes didn't work any more. I'm not so sure the switches are still fully functional when they are near 100%, there might be other processes (other then SSL) that run into memory problems too.
In my logs:
Oct 20 10:10:56 x.x.x.x certificate,error CRL size exceeds free disk space, aborting update
Oct 20 11:10:56 x.x.x.x certificate,error CRL size exceeds free disk space, aborting update
Oct 20 12:10:56 x.x.x.x certificate,error CRL size exceeds free disk space, aborting update

* Is there anything I can do to free up memory?
* Is it still save to upgrade such a router? I'm worried that running out of memory during upgrade might give horrible results in a production environment.
* Is there a way to expand the memory?

I have the same issue on two CRS326-24G-2S+ switches running RouerOS.

On both I had downloaded the "Current" update for implementation on a manual reboot when the client had a factory shutdown.
The Resources page show Free HDD Space as 3896KiB and Total HDD Size as 16.0 MiB.

The decision was made to switch to the latest Bugfix (Long Term Release) and the "Current" update removed.
The disk free disk space did not change and cannot download the Bugfix 6.42.9 update in preparation of a reboot.

The changelog notes for 6.42.9 shows: *) filesystem - fixed NAND memory going into read-only mode (requires "factory-firmware" >= 3.41.1 and "current-firmware" >= 6.43);
I assume this means that a Netinstall is required.
