Disk IDs change after intermittent unmount/remounts

Hello!

I have set up my raspberry pi/sata hat - and everything is going great!

I have my clients connected to my nas and I sleep like a baby.

However, in the morning when I check, my clients have some errors (it looks like they are no longer connected to the nas… strange)

So I check to see what has happened in the “journalctl” and it seems pretty odd… but before I dive in, let me explain my configuration

SBC: Raspberry Pi 4 (4GB)
Hat: Quad Sata hat
NAS Storage: 4x 2TB MX200 plugged into hat
OS Storage: 1x 1tb Kingston storage

OS: Debian 11
Kernel: 5.15.79-v8+
I have installed OMV6 onto the OS (not OMV OS)
I am using OMV “mergerfs” plugin to “merge” my 4x storage drives into one mounted drive (like raid 0), which is exposed over SMB/CIFS/NFS

The 4 NAS drives are the following: (output from: “blkid”)

/dev/sdb1: UUID="2b1fa6c8-6052-4d14-af8a-5f8ae206e9ee" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="c0b1dc87-5d27-4376-b4cf-8272385ae34d"
/dev/sdc1: UUID="132e7114-961b-4cda-b9af-70947ba40914" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="41db4b96-a67f-480e-9fde-67337f378bcc"
/dev/sdd1: UUID="ed512728-130d-4ddb-80bc-1d744d8d0755" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="d27fc8a7-7fef-4409-9bf5-924fae397357"
/dev/sde1: UUID="53632973-1765-4839-aa3b-bd8fff3b1c33" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="534fe7a2-1603-46d4-ad66-0ff0c05edd3c"

I have set in the rockpi-sata.service to “run before” SMB/CIFS/mounting the SSDs:

[Unit]
Before=export-disk.mount srv-mergerfs-mergefs.mount srv-dev\\x2ddisk\\x2dby\\x2duuid\\x2d132e7114\\x2d961b\\x2d4cda\\x2db9af\\x2d70947ba40914.mount srv-dev\\x2ddisk\\x2dby\\x2duuid\\x2d2b1fa6c8\\x2d6052\\x2d4d14\\x2daf8a\\x2d5f8ae206e9ee.mount srv-dev\\x2ddisk\\x2dby\\x2duuid\\x2d53632973\\x2d1765\\x2d4839\\x2daa3b\\x2dbd8fff3b1c33.mount srv-dev\\x2ddisk\\x2dby\\x2duuid\\x2ded512728\\x2d130d\\x2d4ddb\\x2d80bc\\x2d1d744d8d0755.mount 

I have also configured “mergerfs” to “run before” SMB/CIFS and create a dependency on rockpi-sata.service:

[Unit]
Requires=rockpi-sata.service
After=rockpi-sata.service
Before=export-disk.mount smbd.service nfs-server.service

Phew, now the preamble is done, onto the logs…

I (re)booted the Pi at 23:16:

Everything is working well, so time for bed
but while I slept the following happened:

this goes on and on until I wake up
Unfortunatly I didn’t grab the output of df -h, but there was no longer a /dev/sdb or /dev/sdc but there was a /dev/sdf and /dev/sdg! and I’ve just seen in the logs that there is /dev/sdh too!

Here are the logs:
<hit character limit, the first reply will be these logs>

So my question is (finally we get there!):

  1. Why does rockpi-sata.service mount the same drives on different mountpoints if the service is restarted? Is it because mergerfs is still using those mountpoints and needs to be stopped first?
  2. Why does this happen in the first place? I guess there may be some communication issues over USB (everywhere I read online says “don’t do raid over USB!”), but when/if the connection comes back, then the disk should re-mount onto the same mountpoint, and mergerfs should continue as normal right?

Thanks for reading this essay!

I don’t know if there is a software problem in the rockpi-sata.service, or a hardware problem in the sata controller

when I perform an “ls” inside one of the unmounted and automatically remounted disks:

Hello, what power supply are you using? Let’s rule out if the power supply is insufficient.

Hello setq, thanks for responding, I’ve felt a bit in the dark over the past week with this issue - so I appreciate your help

I am using the power supply provided with this kit:

So a 12V 5A PSU plugged into the sata hat (no power plugged into the raspberry pi)

It looks like the power supply is adequate. I want to know how your 1t Kingston is connected, is it connected to usb2.0, is there extra power?

The kingston disk is my OS disk
It is in this enclosure:

(with a usbc to usb A 3.1 adapter, plugged into a USB 2 port)

It doesn’t have external power

USB 2.0 has only 500ma of current and may not make the enclosure work steadily. Or we can try to use an sd card to install the system.

I’ll try that out this evening

In the mean time the error just happened while I was awake, so here is the dmesg output:
