(SOLVED) kernel: SQUASHFS error:

[RichJacot]

I awoke this morning with my log file full.  It's been quite some time since that has happened. I've made no HW changes nor added any new docker/VMs in a long time either.

 

In syslog I'm seeing a lot of kernel: SQUASHFS error: errors.  I've never seen these before.  

 

I've googled some but most of what I'm finding is related to a bad USB flash boot device and they can't boot, which isn't my case.  I haven't tried starting the array yet, I don't want to cause more issues.

 

Can someone help me or point me where to dig deeper please?

Connect the flash to a PC and run chkdsk on it.

I don't have a window machine but with Linux I get:

I'm not seeing an issue with the above but when I tried to make a copy of the USB before running anything against it I got:

As you can see the /dev/disk/by-id/usb* is there before I run the command.  It knocks it out when I ran the dd.  :-/

Looks like a flash drive problem.

[RichJacot]

Makes sense.

 

I've downloaded the backup from my servers and put it on an old USB I had laying around.  I have it up and running now, array not started yet.  Obviously it's saying:  

 

Uptime 7 minutes

•

Unraid OS GUID Error

Purchase Key

 

I'd like to order a new quality USB (which I though I had but it only lasted 14 months).  What's my best option to get this back online today and use a new one in a couple days?

 

I see that it appears they let you transfer the lic. once a year.  I really don't want to say on the old one I had laying around. It's of unknown age and quality.

 

Suggestions for my next steps?

[JorgeB]

You can do an automated key transfer then contact support for the other one.

[RichJacot]

Roger.    Thank you!

 

While I'm doing that does anyone have a better suggestion for a flash drive?  

 

I "HAD" a Samsung USB 3.1 FIT Plus 32GB.   Any better/more reliable then 14 months out there?

Kingston DTSE9H

The old USB 2.0 model, not the new DTSE9G2, that one is garbage.

 

 

[RichJacot]

Ordered one and it will be here Tuesday the 18th.

 

Array is up and all dockers started without issue.

 

Thank you for your help JorgeB!
