Hi folks,
I have a 6 disk + single SSD cache RAIDZ1 setup running on 9.3 latest.
Main disks at 6 x 4TB Reds and a OCZ 60GB SSD for the cache.
I was moving a large amount of data around and decided to look at iostat for laughs. It shows something odd for the SSD though:
Why would it be reporting 589G on a 60GB disk? As the copy continues it does up and up. It's currently at 603GB
Signs that the disk is not happy? A SMART report says all is well. (or does it?)
Thanks
Crispin
