I recently replaced a failed data drive and swapped with a new one and already rebuilt.

 

Quick question. I was due for a scheduled parity check next week.  Do I still need to do a parity check after the drive rebuilt?  My dashboard shows as parity check completed. Was the parity check part of the drive rebuild process?  Is this an accurate assumption? Or I need to start a parity check manually?

A non-correcting parity check is a good idea to confirm the rebuild went well. Looks like you don't run parity check very often anyway.

Thank you Sir.  I will kick it off right now. I schedule parity check every 3 months.  Should I do it more often?

Probably not. I have my main server scheduled monthly, but my backup server, which is rarely on, I just do parity check manually when I feel like it.

Copy that and thank you Sir

Question related to this: If a drive failed on the 30th and a parity check was scheduled for the next morning, what would happen?

 

Edit: by default correcting parity check is left turned on in this hypothetical scenario, and no user intervention is possible. Will the parity check destroy the data, will it stop and not run, what is the programmed response to this scenario?

oops I realized I posted this on a solved thread. Sorry, I'll make a new one.
