Anyone know if there is something equally simplistic and universal than LVM that allows for storage policies?

Aka. instead of needing equally sized disks to get something like RAID-5/6 but with an arbitrary amount of drives in arbitrary sizes? (Without the capacity capping).

For now say like I'd have something silly like this:
4x 5 TB
2x 20 TB
20x 1 TB
1x 500 GB
+ change

Goal:
* Encryption at rest
* Tolerates 2 drive failures without any dataloss at all (by more partial)

#LVM #Linux #Storage

(Not my actual drive count or sizes, I don't have all of them online, nor "inventoried". I don't actually know how many or which sizes I've laying around right now)

Some people said ZFS in the past, but is anyone else actually running something silly like this and knows for sure that it works with ZFS?

#ZFS

@agowa338 no ZFS won't work with that

@raito

Thanks and here I thought I was just too dumb to configure it properly last time I tried.

@agowa338 responded in a other toot, but not ZFS. Not simple by any means, but this sounds like something Ceph can do.

@paxswill

Yea, have heard that, same for GlusterFS. However I neither was able to find anything about unequally sized disks in their documentation nor was I able to find anyone running such a configuration already.

Are you running such a configuration right now?

@agowa338 huh, looked a bit deeper at it and it sounds like it’s not great at this. Welp, sorry.
