I am hoping someone can help me with the following issues I have been experiencing since the end of last year.
My build specs are at the end of this post:
Before I found UnRAID, I used Freenas twice and Xpenology once, but all builds at different times reported I/O errors on different drives.
Since trying UnRAID (Which so far is my favourite by a mile), I added a couple of drives and everything worked fine but when I added a few more as unassigned and starting running Preclear (3 cycles) some drives preclear just stopped while others failed and other passed (All drives show no Smart errors). I tried this while the array is running and suddenly 1-2 array drives failed badly.
I restarted the server and the array drives ran fine with only a couple of small errors but Smart reports were fine and as soon as I run Preclear again the same issues appeared.
It seems to me that when I have a few drives working at the same time, things start to fail which I can now only assume in not the drives but possibly a controller issue. If this is the case, I am now confused as to how to diagnose it further.
I have only installed a few of my total amount of drives so far and do not want to copy all of my data back until I get this sorted.
Any help would be mostly appreciated.
