jdc Posted June 18, 2013 Share Posted June 18, 2013 I had a drive fail today and replaced it. I noticed when I brought the array back online, the shares were available while it is rebuilding. Is it ok to use the array while it is rebuilding? Thanks. Quote Link to comment
aiden Posted June 18, 2013 Share Posted June 18, 2013 Yes, you can use the array while it is rebuilding. That's part of the design. I would suggest you not write a lot to the array during the rebuild, as this will slow things down. Plus it always makes me a little nervous. Quote Link to comment
jdc Posted June 18, 2013 Author Share Posted June 18, 2013 Great. I waited just in case. Thanks. Quote Link to comment
garycase Posted June 18, 2013 Share Posted June 18, 2013 You can use the array while it's doing a rebuild, just as you can use the array during parity checks. HOWEVER, consider what's happening during those operations, and you'll realize that any additional I/O will cause significant disk thrashing on those disks involved in the other I/O. So it will very significantly slow down the rebuild/parity check, and will also be slower at the other operation(s) as well. Bottom line: Except for perhaps "showing off" the ability to do it, I NEVER do anything with the array while running parity checks or during disk rebuilds. I HAVE, on occasion, streamed a couple of movies from a "non-existent" disk (i.e. one that's missing from the array) just to show off the ability to do it. Quote Link to comment
