Usb Flash Drive is corrupted

[Angora]

Hey guys,

 

today unraid started to show me the message, that my flash drive is corrupted or offline. Since its only 3? month old i am a little confused.

What would be the best steps to get it to work again? I thought about restarting but am afraid, if my server wont come back up again. 

 

Also my boot/config/ folder looks a little weired. (See screenshot)

 

Any suggestions or tips, how to handle this?

 

Thanks.

Flash filesystem went read-only, you can try running chkdsk on it, or reformatting, if issues persist replace it.

Just to make sure i do the right thing:

reiserfsck --fix-fixable /boot

Is that correct?

[JorgeB]

Nope, that's for reiserfs, flash uses FAT, I would recommend using scandisk/chkdsk on Windows.

[Angora]

In this case is the usb-stick still installed in the server and unraid still running. For that reason i would use

fsck -a /boot/

 

Sorry if i am asking many questions, i just want to be cautious.

[JorgeB]

I've never tried, but since the fs is mounted it probably won't be able to correct any error, if you reboot it should make a check, but IMHO chkdsk is better.

[Angora]

No progress so far. fsck did not do its thing. 

So, you suggest turning the system off, getting the usb stick and trying it at my pc? Will i be able to turn the system back on again?

 

I turned it off, but chkdsk tells me that there is an unrecoverable error.

 

So... what to do now?

Then the Stick is broken and you need a new one.

[Angora]

Thats what i figured until now, the more precise question is: how to recover all the settings etc? (i made a backup a while ago, but i can only access it via unraid -.-, since i need linux for it)

And how do i get unraid to acknowledge the new usb stick with the bought license?

See here for how to replace the flash drive:

https://docs.unraid.net/unraid-os/manual/changing-the-flash-device/

 

If you cannot copy the /config from the old one and need help with the device assignments see the end of that page.

[Angora]

Thanks already for your help.

 

I bought a new (sadly) SanDisk USB Stick, just to find out, that the usb creater does not like it. Yet i was able to install unraid manually. I copied my old config over, and replaced the kay. So far everything went okay, i guess.

 

I am still wondering how a 3 month? Old Usb-Stick can get this degraded within this time. 

Anyways, for now everything is up and running again. Hopefully for longer now than the last time.

 

Thanks guys, have a nice weekend.

Most current flash drives are garbage, they are not made as they were in the past, but you can still find some good ones, personally I like the Sandisk Cruzer Blade 32GB, one of the few USB 2.0 flash drives still available, and in my experience then tend to be more reliable.
