mdadm in 2018 ??

Also, just because Linux often does things better than windows, windows doesn't really have anything like software raid.
FakeRAID all day long. StorageSpaces is still a bit too new to really trust but would at least warrant investigating.

Mdadm is very easy to use, can you explain what difficulty you're encountering?
@DustinB3403 You really should read my post before replying!

I did, thoroughly. . .

It's easy enough to go in Cockpit, select a few of your non-os disks & create a RAID array of your choice.
It would seem to me, there should be some easy to use utility that would alert you about drive failure (via email) & also include the failed drives serial #.
Auto-rebuild should be automatic once I swap out the failed drive.All the FOSS fan boi's say everything is easier in Linux vs Windows.
Can someone please direct me to any such utility?
Again, I repeat, it must be easy to use!!The CLI is a utility that is easy to use...

The CLI does all this..."alert you about drive failure (via email) & also include the failed drives serial #.
Auto-rebuild should be automatic once I swap out the failed drive."? -
@fateknollogee it can, yes I had this setup at my last job.

But software raid isn't designed for small uses cases, not like hardware raid is.

I never once mentioned anything about use case?

I never said you did, but was putting an assumption out there.

Thanks for the 1st link.
Failed drive serial # ?
Auto rebuild upon swap ?Is this the setup you used on your last job?

That is just one of many articles, iirc it was at least one that I reviewed.
The rebuild portion was a pain in the ass, as the system I had at the time didn't have hot swap, so I had to power down to replace disks.
It's possible but just a huge pain.

@dustinb3403 How about the failed drive serial # alerting, you did have that at your last job?

I had it email the UUID of the disks.

I also had smartctl setup on my xs6.5 hosts at the time and looked with that.

You did not have auto-rebuild?

Pls share, even though UUID is not the same as serial number.

I didn't because it simply wasn't worth it for us, 4 disks, OBR10.

This is called blind swap and it is NOT a good idea. The system does not know how you want the new drive to be used, there is a reason it does not do this. RAID is more complicated than that. If you want MD RAID to do things like that (MDADM is the management utility, not the RAID) you have to cripple it and make it a lot less flexible than it is today.
