I had one of the disks in my cache array fail. No problem, its RAID10 so I'll just swap it out and let it rebuild. After doing a full balance, a convert to RAID10 again, I get the following for status.
Data, RAID10: total=222.00GiB, used=156.09GiB
Data, single: total=3.00GiB, used=2.63GiB
System, RAID10: total=64.00MiB, used=0.00B
System, single: total=32.00MiB, used=48.00KiB
Metadata, RAID10: total=2.00GiB, used=906.00MiB
Metadata, single: total=1.00GiB, used=154.20MiB
GlobalReserve, single: total=188.30MiB, used=4.33MiB
I'm also being told my cache is ~2TB in size instead of ~1TB in size (4 600GB 15k SAS drives). Anyone have a suggestion on what could be causing this?
