rockytt Posted April 3 Share Posted April 3 Hi all - running my monthly parity check and it is sooooooo slow all of sudden. I don't see anything obvious in the syslog - but I'm not an expert here and could use another set of eyes. This current setup is a couple years old at least - with a few disks being swapped out of course Nothing looks amiss after running DiskSpeed Running 6.12.9 tower-syslog-20240402-2344.zip Quote Link to comment
itimpi Posted April 3 Share Posted April 3 You are getting a small number of retries on ata1 and ata4 in the syslog but I would not have thought they were enough to have much impact on the speed. Others have found that this frequently means that you have other disk activity going on at the same time to array drives which is badly impacting the speed. If you provided your system diagnostics we could determine if this is the case. Quote Link to comment
rockytt Posted April 3 Author Share Posted April 3 Thank you - very curious to see what the diagnostics show - attached! tower-diagnostics-20240403-1013.zip Quote Link to comment
itimpi Posted April 4 Share Posted April 4 There does not seem to be a parity check running when those diagnostics were taken. Would need some taken while you were experiencing the problem. Quote Link to comment

Solution JorgeB Posted April 4 Solution Share Posted April 4 Check/replace cables for disks 9 and 13 Quote Link to comment
rockytt Posted April 4 Author Share Posted April 4 thank you - will do so and report back! Quote Link to comment
rockytt Posted April 6 Author Share Posted April 6 When I checked today, disk 13 was red balled - shut it down, swapped in new cable, powered up and unassigned the disk, started in maintenance mode, stopped array again and reassigned the disk to the same slot. Data is rebuilding on disk 13 at 155mbs - so looks like that cable was (very) bad - thank you for the help! 1 Quote Link to comment
