Netgar ReadyNas 516 New Drive Install Seagate-Command Timeouts
Problem with ReadNas 516 Diskless Firmware on NAS 6.75 All New Drives Seagate ST6000NE0021 3 No Problems with new install in a used NAS except for Disk 3 has 20 command timeouts, Disk 5 has 7 Comm...
I haven't seen this myself. I believe the drive counts ATA errors, but the OS drivers might be counting the command timeouts. If so, I think that an issue with one drive can cause sata bus timeouts on other drives.
Can you look in disk_info.log, and see if there are ATA errors there (and if they are tracking the command timeouts)?
I'd wait a while and see if the counts continue to rise.
It could be that disk 6 is bad though.
There was a 4th drive that I sent back at 17,000+ timeouts
But the question is is this normal "all drives seeing command timeouts and all being new??

This is the log you asked for no ata error at all

I'd watch it longer, and see if the count on any disk continues to climb. Scheduling a scrub is one way to create a lot of disk activity.
The one I'd watch most closely is ZA16K95A. If you still can exchange that for free, then maybe just do it as a precaution.
