[OpenIndiana-discuss] ZFS single drive CKSUM errors

[Michelle Knight]

Thanks folks,

The drives are desktop drives, 1.5tb seagate baracuda LP units. They seemed to 
be perfectly happy when inside the machine attached to motherboard sata 
channels.

In this case, they are on the single e-sata channel of the motherboard, with 
no raid going on either in hardware or software.

I have backed up two segments of my data drives to two of these backup drives 
now and they have both exhibited this problem.

I'm starting to conclude from what people have said, that it is most likely to 
be a time out issue.

Taking the time at the start and end of transfer indicates that overnight it 
transfered at 0.335Gb/sec - potentially handling 1TB in 8 hours 18 minutes.
