zfs discuss - Nov 2006 - What happens when adding a mirror, or put a mirror offline/online

Hello,

Sorry if my question is a newbie question, but I am not an administrator
familiar with storage, I am just curious about ZFS. I tried to look for an
answer in the ZFS documentation and the mailing list, but I found nothing
obvious.
Can you tell me what happens when an additional device is attached to a mirror ?
Does ZFS starts replicating the data on it ? Is it delayed ? What''s the
strategy ? The same question occurs when putting a part of a mirror offline.
When it comes back online, how is the data checked for out-of-date parts ?
ZFS is totally new for me, and I find it very insteresting to understand what it
implies.

Regards,

Pierre Chatelier

I finally found the answer myself.
By re-reading the doc, I re-discovered the term" resilvering", that I
did not understand properly the first time.
