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)?
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

smart_history.log shows the changes in key SMART values over time.
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.
Thanks for the feeback- I had moved all drives around durring the process of troubleshooting. (prior to removing the 17,000+ error drive) But also did notice from the time of that post that there were no more warnings and and the count did not move. It seemed that
the bad drive I sent back was causing all the warnings which did increase incramentally as the drive created a volume and resynced.
At some point I cleared the log did a factory reset and then all warnings stopped, the drive now has the same amount of timeout errors that it did prior to the factory reset, with no error messages as well as no incremental upgrades to these numbers I posted. Hopefully When I get my new drive and install it I can find out which came first the chicken or the egg? It does seem that one bad drive can make all the others begin to incrementally increase and report timeout errors, as this was the case. ZA16K95A is suspect still, but there are no error messages and again no increases in timeout count. I will wait for the new drive and resysc the volume and watch. New does not mean good, just untested thanks!!
I will report my finding shortly.
