I am planning on creating a home server with either 2 (RAID1) or 3 (RAID5) HDDs as bulk storage and 1 SSD as bcache.
The question is, what file system should I use for the HDDs? I am thinking of ext4 or xfs, as I heard btrfs is not recommended for my use case for some reason.
Do you all have some advice to give on what file system to use, as well as some other tips?
I would absolutely recommend a file system with snapshot capabilities for a home server. One of btrfs mirror, dm-raid (raid5) with btrfs, or zfs would work. The practical differences would be negligible at this scale and you can just pick whatever you fancy.
