yippy3000 Posted October 4, 2016 Share Posted October 4, 2016 As the title says, my parity check is extremely slow. I see people complaining about 10MB/s being slow and I am getting less than a quarter of that. What can I check to figure out why. Diagnostic information attached. My System: CPU: Intel® Xeon® CPU E3-1230 v5 @ 3.40GHz RAM: 16GB DDR4 ECC MB: ASRock E3C236D2I Mini-ITX SATA: Onboard, M.2, SYBA SY-PEX40039 Plug-in Card SATA III Cache: ADATA SSD SP600NS34 256GB KingDian SSD S280 240GB Pool: 3x WD Red 4TB 1x Seagate ST4000DM000 4TB 1x Hitachi HDT721010SLA360 1TB Parity: Dual (1 WD Red and the Seagate) aeris-diagnostics-20161004-1045.zip Quote Link to comment
trurl Posted October 4, 2016 Share Posted October 4, 2016 Lots of read errors on disk2 (which you should see in the webUI if you look), but SMART looks OK so maybe just a bad connection. Quote Link to comment
yippy3000 Posted October 4, 2016 Author Share Posted October 4, 2016 I actually don't see any read errors in the UI, where would I see that? Sounds like I might need to start considering replacing that drive. Quote Link to comment
JorgeB Posted October 4, 2016 Share Posted October 4, 2016 Errors should be visible on the main page. Although there are no pending sectors errors look like a bad disk, you can confirm by doing an extended SMART test. Quote Link to comment
yippy3000 Posted October 4, 2016 Author Share Posted October 4, 2016 Ah, found it, yes, it shows 482 errors. I am playing it safe and just ordered two replacement drives (going to get that 1TB out of there as well). Side question, anyone see any issues with this as a home NAS drive, other than the heat (I realize the REDs are lower power) http://flash.newegg.com/Product/9SIA5AD4NC7705 Quote Link to comment
