raid10 on three discs - few questions.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Maybe I'll buy three HDDs to put a raid10 on them. And get the total
capacity of 1.5 of a disc. 'man 4 md' indicates that this is possible
and should work.

I'm wondering - how a single disc failure is handled in such configuration?

1. does the array continue to work in a degraded state?

2. after the failure I can disconnect faulty drive, connect a new one,
   start the computer, add disc to array and it will sync automatically?


Question seems a bit obvious, but the configuration is, at least for
me, a bit unusual. This is why I'm asking. Anybody here tested such
configuration, has some experience?


3. Another thing - would raid10,far=2 work when three drives are used?
   Would it increase the read performance?

4. Would it be possible to later '--grow' the array to use 4 discs in
   raid10 ? Even with far=2 ?

thanks,
