Got a red X by one of the drives

Unfortunately, I did a reboot before doing the tools > diag download. 

 

Her's what I have after reboot....

 

thoughts?

 

Thanks

Disk shows some SMART warning, but without the pre-reboot diags it's difficult to say, at least run an extended test before rebuilding.

How to run the extended test that you want ?

Main - Array Devices - click on the disk number to get to its page, where you will see the self test.

here you go

FYI - it says that it completed without error. Shall I send a screenshot as well?

Disk looks OK. You have to rebuild to enable the disk. Unfortunately we still don't know what caused it to be disabled since you didn't get us a diagnostic that included the event. Often these are caused by a bad connection, or maybe a bad cable.

 

The safest thing is to rebuild to a new disk and keep this one in reserve in case there is some other problem rebuilding. You can also rebuild to the same disk if you don't have a spare.

 

unRAID disables a disk when a write to it fails. But that write and any subsequent reads or writes are emulated by the parity calculation using parity and all the other disks. The data on the physical disk is now invalid and out-of-sync with parity, but the valid data can be rebuilt from the parity calculation.

 

Do you have a spare or do you want to rebuild to the same disk?

Don't have a spare. However, the data on this drive is for Security camera videos for BlueIris. So, its not critical even if the data is lost. The critical data is backed up to a remote Raid 1 array, elsewhere. So, let's try rebuilding the disk. Its still under warranty. If it fails again, I'll hassle WD for a replacement. I've only got 35% used on my whole array even with this drive down.

 

gonna ask this because I'm lazy - what to do to rebuild? I'll understand if you wanna yell at me and redirect me to search the forums. lol. 

 

Thanks

 

Stop array. Unallocate disk. Start array. Stop array. Allocate disk. Start array. Disk will rebuild.

 

I was going to make you do some work by pointing you to some other page that explains this but I couldn't find one quickly enough so it was simpler just to spell it out
