March 2, 20224 yr Hello, need help, my "parity check" is very slow, it estimates 46 days to complete, usualy it took 15 hours, i'm a noob on this things, read a lot of post here but didn't understand how to fix my problem rebooting the server or disabeling the dockers didn't work. cheers nas-diagnostics-20220302-0654.zip
March 2, 20224 yr Community Expert Run a read test with the diskspeed docker to see if all disks are performing normally.
March 2, 20224 yr Author Hello JorgeB, thanks for taking the time to help me, looking at this (and if i read this correctly) Disk 4 is losing performance and Disk 3 is "dead"? what's your opinion? what should i do? PedroFerreira_20220302_213102.tar.gz
March 3, 20224 yr Community Expert Solution Disk4 is OK, it's smaller than the other ones so it slows down sooner, disk3 needs to be replaced.
March 4, 20224 yr Author Hello again JorgeB, Just to report as you suggested i replaced Disk 3, took about 8 hours to rebuild a 4TB drive and my problem is solved. In my defence this wasn't the first hard drive that malfunctioned. The first drive i changed, i had a notification on my "dashboard" and a "red thumb" warning. On this drive i had a "green thumb" and no notifications warnings, just slow, very slow speed when performing the "parity check", this completly throw me off. Once again thanks for the tips. And now a print of my normal speed 170MB/sec , not 46 days 513kpps
