BTRFS 1 disk

Unread post by porkchop1 » Wed Dec 06, 2017 7:01 pm

Hi,
is BTRFS supported with only 1 disk ?

I'm planning on getting the DS218+ and setup two separate volumes with no RAID/disk fault tolerance.

Most important to me is that the filesystem can protect against silent corruption. Offsite backup will be done, but I need to ensure data integrity.

You have 2 completely opposite requirements.

Yes, you can create just 1 disk btrfs volume without data protection.
No, with that setup, you will NOT be protected against silent corruption, because system will not have healthy backup of file available, thus it cannot repair that file.
