Reallocated sector ct & Faied USB key

[SliMat]

Morning guys

 

I needed to reboot my home UnRAID machine today and received a flurry of concerning alerts...

 

Event: Unraid device dev2 SMART health [5]

I am guessing I have a rapidly failing dev2 as I had these 3 warnings by email in the order above?

 

Also a failed USB key (?) - It has booted into UnRAID, which surprises me if the key has failed! I have checked on Connect and it shows the last backup as this morning when I shut the server down;

 

 

I am assuming these are 2 completely separate faults and a replacement HDD and USB key will fix things?

 

If I get a replacement USB key, am I better off copying the 'failed' one or restoring from Connect?

 

Diags are attached.

 

Thanks

It looks like the device reporting issues is an Unassigned Device (/dev/sdi) rather than an array or pool device?

 

There IS a message in the syslog about a failure to read a block from the flash drive but I wonder if that is a side-effect of the drive showing problems (particularly if that drive is connected via USB) rather than a genuine problem with the flash drive.   You could try the process described here in the online documentation to rewrite the bz* type files - it will not do any harm and sometimes fixes being able to read marginal blocks from the flash drive.

Thanks @itimpi

 

/dev/sdi is a SATA disk which I use purely for CCTV recordings, so it is not part of the array as it is a sacrificial drive which is permanently being written to... so, if its failing I'll just replace it.

 

I was more concerned about the error showing on the Flash drive as I have never had a flash drive error. Ironically because of the age (10yrs +) of the USB disks I am using, I have just replaced the one in a rack server I have at a datacentre. The key in this machine is even older and does occasionally fail to boot and I have to reboot the server to get it to boot into UnRAID - so as a precaution I have ordered an 8Gb USB 2 key to be here tomorrow.

 

I will try following the process mentioned above when I get a chance tomorrow just to see what the outcome is.

 

Thanks again
