Btrfs with different file systems for different mount points?
Hey,
I finally bought a SSD, and I want to format it to f2fs (and fat to boot on UEFI) and install Arch on it, and in my old HDD I intend to have /home and /var and try btrfs on them, but I saw in Arch wiki that btrfs "Cannot use different file systems for different mount points.", it means I cannot have a / in f2fs and a /home in btrfs? What can I do? Better use XFS, ZFS or ext4 (I want the faster one)?
Thanks in advance and sorry my english.

Re: Btrfs with different file systems for different mount points?
Please link to the pages that said this.
I use btrfs as /, xfs for $HOME/Videos, ntfs-3g for $HOME/Documents, and ext4 for /media/steam-ext4.
No problems here..

It's on btrfs article...
https://wiki.archlinux.org/index.php/Btrfs#Partitioning
Just a curiosity: why xfs for videos and ext4 for Steam? And do you recommend btrfs for home folder?

If you notice, that's talking about using BTRFS on the entire disk without any partitioning. Of course you can't have any other filesystems in that setup.

Gosh, what was I thinking, thank you! (I still have a doubt: is btrfs the best option?)

Re: Btrfs with different file systems for different mount points?
Even though btrfs is considered stable, it's still under heavy development (especially some of the more advanced features) and there has still been some quite serious bugs.
Btrfs is definitely not the best choice for storing anything you don't want to lose, at least without taking systematic backups. This probably applies for f2fs as well..

Just a few weeks ago many of us were worrying about massive data loss due to a bug introduced in kernel 3.17 that caused corruption when using snapshots. Because btrfs is under heavy developement, this sort of thing can be expected. That said, I have my entire system running with btrfs. I have 4 volumes, two raid1, a raid0 and a jbod. I also run rsync to an ext4 partition and ntfs. Furthermore I make offline backups as well.
If you use btrfs make sure you have backups and make sure you are ready to use them. Also, make sure you check sum your backups. rsync has the option to use checksums in place of access times to determine what to sync.
