RAID5 can be used normally while rebuilding. Albeit at reduced performance. It's definitely NOT read only as that is effectively the same as offline in a production environment.
- nine_k 8y agoDepends on your usage pattern. You might be hesitant to allow writes without redundancy, especially if you store something important which is mostly read-only anyway (e.g. 95% of operations are reads). For a large write-heavy setup + "we will restore from yesterday's backup" mode of operation, you may likely be better off with a RAID10 which is faster. (Though RAID50 and even RAID60 are a thing.)
- overcast 8y agoSure, but it's not offline, ever. The debate isn't about the best RAID level for your usage.
