Scheduled parity check

[Simone Valmacco]

Hi,

I'm barely new to Unraid.. How often do I have to check the parity for best performance? 

Thank you very much!

Best regards

Checking parity does not affect performance (except while the check is running).   It is a housekeeping task to confirm the array is in a healthy and consistent state.   While a parity check is running array performance is degraded so you do not want to run it too frequently.

 

Probably the commonest frequency chosen is once a month, but others go for something less frequent like every 2-3 months.  If you have large drives you may find the Parity Check Tuning plugin is worth installing to give you more control over the process.

Thank you very much! My drives now are 14TB each, I'll configure to run parity check once a month and I'll have a look at the plugin you told me :)
