so a couple of days ago my parity drive started spitting out UDMA errors. it ran up to 5155.

 

i changed the sata cable, run a full SMART check and rebuilt the array. now fix common problems is telling that there are hardware problems and to post my log file. see attached. the UDMA error has not increased.

 

a quick scan down syslog shows lots of md: disk0 read error, sector=11252103536 etc.

 

is my shucked 8TB drive screwed?

 

or do i just acknowledge the error and forget about it.

 

on another note, can i swap my other 8TB drive to become parity? my array is 2X 8TB and 2X 6TB.

The hardware errors are because your RAM is going bad

Reseat it on both ends, and the power cabling. Outside the the CRC errors, it looks good.

i have a 8 6 port sata cable so just switched to a new port completely and pulled and re-seated the power cable.

 

ram going bad never seen that before (but this is the first time i'm using full on server hardware) is it worth a re-seat and run memtest, or is the module screwed?

 

amazingly fast response Squid!!!

 

edit, so the shouldn't worry about the disc read errors, should i swap the parity drive anyway?
