Slow parity sync help

Featured Replies

Posted

My build was based on the Supermicro SAS controller that was so popular for many years.  Parity syncs have always been somewhat slow.  That controller would crash occasionally and mark 3-4 drives as missing.    That happened again today, so I finally swapped it for a Dell H310

 

right now, my parity is syncing at 33MB.  It does increase after a while, sometimes.  I have attached a log to see if anything jumps out.

 

EDIT

 

after 30mins it is now up to 125MB.

 

Is this slow start normal?

 

Thanks

There could have been some array activity or some disk(s) getting slow sectors, monitor the next check.

I was doing some looking around and realized that the drives plugged into my motherboard ports are only operating at 3G rather than 6gs. Will I noticed any Improvement if I buy another HBA?

SATA2 is more than enough for current hard drives, SSDs are a different story.
