Ok so the capacity is ruled out, it still bothers me that after experiencing the error if I do a 'zpool status' it just hangs (forever) but if I reboot the system everything comes back up fine (for a little while). Last night I installed the latest SXDE and I'm going to see if that fixes it, if

Since zfs is so smart is other areas is there a particular reason why a high water mark is not calculated and the available space not reset to this? I'd far rather have a zpool of 1000GB that said it only had 900GB but did not have corruption as it ran out of space. Nicholas __

I was hoping that this was the problem (because just buying more discs is the cheapest solution given time=$$) but running it by somebody at work they said going over 90% can cause decreased performance but is unlikely to cause the strange errors I'm seeing. However, I think I'll stick a 1TB dr

It is not recommended to store more than 90% on any file system, I think. For instance, NTFS can behave very badly when it runs out of space. Similar to if you fill up your RAM and you have no swap space. Then the computer starts to thrash badly. Not recommended. Avoid 90% and above, and you hav

I've run into this problem twice now, before I had 10x500GB drives in a ZFS+ setup and now again in a 12x500GB ZFS+ setup. The problem is when the pool reaches ~85% capacity I get random read failures and around ~90% capacity I get read failures AND zpool corruption. For example: -I open a dir
