is my cache pool working?

[ideasman]

hey there,

 

so i remember trying out unraid back in 2018 but wasn't set on it. looking at it again and it seems its come a long way!

 

i've just installed a fresh copy on the following hardware:

- core i5 11400

- gigabyte b560m aorus pro

- 16gb ram

- 6 x 4TB hard drives

- 2 x 500GB nvme

 

The array has the 6 x 4TB drives with a single parity and the 2 x nvme drives are configured in the same cache pool.

 

Currently the parity is syncing but i'm curious about the cache pool - should i see writes happening on both nvmes? I've been clicking around in the interface to try find a "status" of the array but I'm not sure what I'm looking for.

 

Cheers!

 

Edit: clicked the “cache” and noticed this:

Data, single: total=46.01GiB, used=44.78GiB
System, DUP: total=8.00MiB, used=16.00KiB
Metadata, DUP: total=1.00GiB, used=35.36MiB
GlobalReserve, single: total=25.34MiB, used=0.00B

 

tried selecting the “switch to raid 1” but still no writes on the second ssd

Currently only the WD SSD is in the pool, stop the array, unassign the Samsung NVMe, start array, stop array, re-assign the Samsung NVMe, start array and that should fix it, in doubt post new diags.

Perfecto! Thanks mate. I was thinking I’d have to move everything off the cache and rebuild the whole thing again. 
 

did exactly what you said, it balanced and it’s now happy (so am I 😁)

 

 thanks again!
