I changed the configration on the areca arc-1680-card and put all
disks in throughput-mode and is now able to copy large amounts of data
(more than 1 TB) without problems. I have 'zpool offline'd a disk and
'zpool replace'd it with a spare. The resilver is progressing as
normal and the zpool is accessible.


When lenity and cruelty play for a kingdom,
the gentlest gamester is the soonest winner.
