Hello all,

My system has been working pretty well for a while, thanks to this group. However I have noticed that my array does not seem to be filling up in the manner that I thought it was supposed to. the first Five 4tb drives filled up to 50% one after another. The next two 2tb drives filled to 500gb each and the next drive a 6tb drive has filled 4.46 tb so far.... this does not seem logical to me. Simple question is am I over thinking it?

 

I also have drive 12 that showed up with 78 errors this AM, I am not real familiar with Smart errors, Do I need to pull that drive or is there anything I can do to correct the errors.

I am attaching the diagnostic.

 

Thank you in advance for your help

Chas

Unlikely to be a disk problem since just before the read errors there where issues with multiple disks:

Check if these disks share anything in common besides the controller, since not all disks there were affected.

Ohh, and for the other question see:

https://wiki.unraid.net/Un-Official_UnRAID_Manual#High_Water

 

Nothing in common that I see other than the controller, different manufacturers and different sizes the drives are not consecutively mounted . 

Thank you for the link to High_water, that clears up my misunderstanding.
