Hello everyone.
New guy here. I just setting my Unraid unit. Got some used disks and new ones.
I used this Preclear plug-in for check up and one of my new disk came with strange output. I was hoping someone here could help me out to figure out whether I got a bad disk or there might be something wrong with Preclear.
At the end, Preclear says it was successful.
And here's some output. Please note that I got two pause and resume, due to Array Restart.
In Second attachment, Preclear Log, from line of "Aug 11 09:53:57" I started getting strange message, and eventually Preclear killed hung process.
