1 parity and 1 data disk array clarification

[baby0nboardInSg]

Hi I'm fairly new to unraid and started using with a 1 parity disk and 1 data disk setup. ( both disk are extras i used for my small home server)

 

After 6 months of no problems, the data disk finally showed some read errors.

 

Since i only have 1 parity and 1 data disk, should following this guide be enough to replace my data disk? https://wiki.unraid.net/Replacing_a_Data_Drive
I'm not sure if my parity disk is enough to restore the data disk.

I could not search previous discussions so I created one, i just want to make sure before I replace my data disk.

Yes, procedure is the same, you might want to post the diagnostics first though.

Hi Jorge, thank you for the reply. 

 

did you mean the diagnostics from the disk itself? I've attached the whole diagnostics.

please help to give feedback. Thanks

It does look like a disk problem, though possibly an intermittent one, so not a bad idea to replace it.

Since parity is 3TB, and data disk is 3TB, you can only replace data disk with 3TB using that procedure from the wiki. If you want to use a larger disk there is a way but slightly more complicated. Let us know.

yeah thank you Jorge and trurl.. I did read the more complicated procedure you mention, and as of now.. the data is enough, i'm only using it as backup for photos with nextcloud for helping for auto uploads.

 

thank you and I think my curiosity has been fed.

Just to be clear, you mean there is a second copy of everything important not on Unraid, and Unraid is keeping a duplicate for you? Unraid by itself is not a backup.
