Hey guys,

 

i do have a severe problem with my unraid server.

my parity disk1 kept restarting on parity checks (Seagate Ironwolf 8Tb CMR).

Smartchecks are clear and free of errors. 

Even though i've replaced the disk with a new disk same type.

I've changed the sata cable and powercable and my new drive keeps doing this while rebuilding parity information.

on every disk-restart parity checks slows down due to the spinup of the disk.

 

with the new disk rebuild runs longer until paritydisk1 restarts.

 

do you have any idea?

 

Diagnostics log is attached.

 

Thanks alot

 

sideinfo: i've enabled encryption on my array so i have to rebuild parity.

I've enabled the smart value "command time out" on both parity disks and parity disk2 gets errors.

is this something to worry about!?

should i change to single parity until the source error is found?!

 

 

Constant ATA errors on both parity disks, replace/swap cables, including power and try again.

Ok thanks,

 

cables are already ordered. Will arrive monday.

could you tell me where you found these errors? 

You can see them in the syslog, see if they go way after the cables swap:

Currently ATA2 is parity, ATA16 is parity2.

 

Changed Powercables...Problem is gone. 

I was able to rebuild parity without errors. the "safety" parity check was also clean.

 

Thanks alot
