Hi guys,

 

I need your help. I want to upgrade my parity drive from a 4tb to a 5tb drive, so I have precleared the new drive twice already successfully and before I wanted to change the drives I ran a parity check without correction and after 18 hours it told me that there was 1 error which is one block, the next parity check I ran with correction and it says it was corrected:

 

Dec 25 09:34:40 Tower kernel: mdcmd (427): check CORRECT

Dec 25 09:34:40 Tower kernel: md: recovery thread woken up ...

Dec 25 09:34:40 Tower kernel: md: recovery thread checking parity...

Dec 25 09:34:40 Tower kernel: md: using 1536k window, over a total of 3907018532 blocks.

Dec 25 23:25:42 Tower kernel: md: correcting parity, sector=5792661424

Dec 26 02:17:54 Tower kernel: md: sync done. time=60193sec

Dec 26 02:17:54 Tower kernel: md: recovery thread sync completion status: 0

 

I guess I found the error now after all

Dec 25 01:10:04 Tower kernel: md: parity incorrect, sector=5792661424

 

so as this was corrected can I go ahead and swap the parity for the new drive?

When you swap parity it will just rebuild parity from scratch so whether you corrected that parity error or not didn't matter.
