I don't like btrfs, this seems to be the default fs for the boot

Anything is better than btrfs, even fat32 which I ended up using for the
boot partition! Been running solid with no issues upgrade after rolling
upgrades.


People love talking smack about btrfs. Here's some real insight from Josef Bacik though at https://lwn.net/ml/fedora-devel/03fbbb9a-7e74-fc49-c663-32722d6f75a2@toxicpanda.com/  and https://lwn.net/ml/fedora-devel/cf5b4944-74c4-b4a4-0d65-71d9821a4a71@toxicpanda.com/. Read through the chain. For those who don't know him, Josef is a core btrfs developer. I also quite like Josef personally, he is a good developer, great to work with and is personally invested in helping folks out.

This is a solid fs, there are times when I see the reactions from users and I really wonder why I do open source work anyway. I have lost data on all sorts of filesystems, and I have also been at the end of stupid mistakes made. Almost everything is recoverable if you stop, and ask for help and keep your ego out of it.


I have used a number of file systems over the years.
from ext in the pre-1.0 kernels through Reiser and XFS.

And I have had problems of one form or another in all of them but none managed to blow away all the data that was less than 3 months old after a power failure.

fortunately the several hundred files were not critical.

Before this my take on the various BTRFS complaints were that people were likely using corner case features.

But having my data scrubbed without a hardware failure is just down right confidence destroying.
If I cannot replace the functionality of ext without having data corrupted then I am not going to use any of the other wonderful features of BTRFS.

Not sure how you would define it but my take is that bulk data loss with no indication of errors is the opposite of solid.

just my $0.02
