Parity speeds problem

[Jederek]

im pretty noob about unraid 

i tried to search for similar problem but didnt find any that fit the description.

 

i have a 23tb array

i rebooted my unraid server last week and did a parity check and it went at 1mb/s instead of 100mb/s

i canceled and rebooted a couple of time but nothing changed.

now i updated unraid to 6.6.5 and it did nothing.

usually it took 10h but now it say 23 days lol

what may be the cause of the problem?

Post your diagnostics from when a parity check is being run.

 

Have you tried adjusting your Tunables?

[Jederek]

i think this is the file you asked

as for tunables i didnt touch that i dont even know what it is... sorry

In the bios change the onboard SATA controller from IDE to AHCI and try again.

i tried some tips ans retried again a parity check and it still slow

i checked the diagnostic file and i found this:

i have no idea what it mean or if its usefull lol

i changed it but still the same speed.

I expected so, there were ATA errors before but because it was in IDE mode it was affecting two disks, now we can see it's disk1, replace cables if errors persist it's likely a disk problem.

[Jederek]

neverming i changed the sata cable as you said and it worked! 

thx a lot!!
