Well, that's all good until RAID goes down - your notes will only be partially useful then as there are many scenarios. Normally after the failed drive has been replaced the array should pick it up but if it doesn't the real fun begins.
- majidazimi 9y agoSoftware RAID is for you. Hardware RAID is only useful if you are buying the high end ones. Other than that software RAID is more flexible and is less susceptible to failure.
- dvfjsdhgfv 9y agoI also use software RAID. Nevertheless, it's not infallible. Recently a disk in one of the arrays went down, it got quickly replaced, but the server wouldn't boot. I had to connect via console and reinstall Grub - only then would the server boot and rebuild the array. A few weeks ago three disks failed at once. In cases like this the parent's notebook will be of limited use. In my experience traditional disks fail every 3-5 years - it's not something you can avoid.
- dx034 9y agoif you have several servers you can either wait until the drive has been repaired (by the hosting provider) and just reinstall. If you need it more quickly you can spin up a new dedicated server. Many providers will set up bare metal servers within a few minutes (as long as the demand isn't too big). It doesn't give you the ability to scale 1000x within a few hours but that won't be a problem for most.
