The whole point of raid is to minimize downtime - that means that if a
disk fails, you can remove it, replace it, and resync while everything
is running (albeit a bit slower).

Thanks for clarifying, Neil. I actually came across this on someone's
blog explaining how they got RAID10 (with imsm metadata) up and running,
and he mentions that he made sure to wait until resync was done before
mounting. I did the same thing, thinking that maybe I might break
something if I didn't.

Hello,
Just wanted to make sure if this was a myth or not: Is it true that
when
an array is in resync status, then mounting it is not at all possible?
Pure myth. Where did you hear it?
Best approach is to try .. if it is not at all possible, then it won't
work.
But in fact it does :-)
