Hi all,

It's been a long... years at work and my brain is fried currently with no bandwidth to properly determine how to migrate a BTFRS array from unraid over to proxmox. I can see the array in proxmox and am able to mount it but now I cannot for the life of me figure out how to

  1. verify that the data is intact
  2. assign it to a storage pool for use in vm's
  3. view it within proxmox

I haven't touched proxmox in years after settling on unraid a while back, but am looking to move back to a non-unraid config.

Anyone here have experience with btfrs and proxmox? Any good links to a tutorial or video?

Thanks!

Sure...so I'm confused why you're bringing XFS to the conversation.

for some reason i read xfs instead of btrfs....

their array implementation is stupid and smart at the same time. I love that you can mix and match disks at random, even with different filesystems (you can have one drive in murderfs, one in xfs, one in btrfs and the last one in zfs and all protected with the same parity drive), but i completely hate how my server is locked by a 25% iowait due to how much cpu intensive is their softraid. Maybe when they came out with this system 20 years ago it was groundbreaking, but now it is stupid. Now with unraid 7 released one week ago they're starting to deprecate it (disabled by default in new install) in favor of native btrfs or zfs arrays
