Subject: Suggestion for hot-replace
Date: Sat, 24 Nov 2012 22:37:49 -0800 [thread overview]
Message-ID: <50B1BCBD.70306@zytor.com> (raw)
I was looking at the hot-replace (want_replacement) feature, and I had a
thought: it would be nice to have this in a form which *didn't* fail the
incumbent drive after the operation is over, and instead turned it into
a spare. This would make it much easier and safer to periodically
rotate and test any hot spares in the system. The main problem with hot
spares is that you don't actually know if they work properly until there
is a failover...
