Subject: What does --replace actually do?
Date: Fri, 15 Apr 2016 21:26:48 +1000 [thread overview]
Message-ID: <5710CFF8.70508@eyal.emu.id.au> (raw)
When I request to replace sda with sdj (RAID6 in my case), does it create sdj from the
other members (NOT using sda) or does it make a copy of (by reading) sda?
I hope it is the former, assuming sda is having issues and the action is precautionary.
I see on stackexchange is mentioned that it actually does the latter:
http://unix.stackexchange.com/questions/74924/how-to-safely-replace-a-not-yet-failed-disk-in-a-linux-raid5-array
And while I am here, can I replace two members at the same time? This should save time
as it takes about 10 hours to reconstruct a 4TB member.
TIA
