Hi! I have a Buffalo TeraStation ES 4TB storage and I've got a couple questions:
I have RAID 5 array on hard drives 1-3 and drive 4 works as a hot spare disk.
1. Does Raid 5 work properly with 3 hard drives overall? In other words, if one of drives 1-3 fails, can the data be recovered by changing the broken hard drive (even if there wasn't the hot spare drive)?
2. Now drive 4 works as a hot spare drive. If let's say drive 1 fails, will TeraStation make a new Raid array from drives 2-4 and leave disk 1 out of it and everything will work seamlessly all the time? When I change drive 1, can I make it a new hot spare disk?
Or am I totally wrong? If I am, please someone tell me how I should do when one of the drives fail (step by step). Cause in that situation I will be in a panic though I have another drive that backups my terastation once a week. It will make me feel comfortable when I know exactly what I have to do in situation when one drive fails. I wanna know how to seamlessly and without losing my data recover the situation that I have raid 5 array with 3 hard drives and one hot spare drive.
