    Who here has used btrfs recently?
    Does it work well?

      @Hyolobrika For laptop use you want either ext4 or f2fs, depending on if the laptop has a HDD or SSD.

      Btrfs doesn't offer any real advantage over ext4 unless you want to do RAID.

      I'm setting up a laptop, not a server.

      I ask because the OpenSUSE installer had it selected by default. I'm not sure whether to go with that or Arch though.

      @Hyolobrika@social.fbxl.net It seems to perform worse than #ZFS for me, storing large volumes of data and for databases (PostgreSQL). However, for a very large number of smaller files (tens of thousands, under 4KiB) it seemed to perform slightly better and took slightly less space on-disk to store it.

      In practice, it works "okay" enough to use for various setups, but I wouldn't trust it for serious large-volume storage unless you have very rigorous backups. I've seen it fuck up too often to trust that well. Be sure to avoid #BTRFS' raid 5/6 at all costs, I haven't heard much problems about their other raid options.

      @vhns F2FS is designed for flash memory that is managed, like SD Cards, flash drives or SSD's - it's designed to reduce the amount of writes, while also increasing speed.

      Unmanaged flash needs a filesystem like UBIFS.

      @Suiseiseki @Hyolobrika isn't F2FS exclusively thought for devices where there isn't an abstraction over the flash memory? i.e not the case for SSDs.

      @Hyolobrika @Suiseiseki changes which affect filesize may not cause fragmentation but it's not guaranteed, and on a CoW filesystem with low space the changes inevitably lead to fragmentation

      whereas on a traditional filesystem it's possible that if the file size is not changing the data could just be changed in place.

      Doesn't copy-on-write make it use space more efficiently?

      @Hyolobrika CoW uses space less efficiently, as you often end up with 2 copies of the same file, although it's useful in the case where the power goes off just as the new version is being written - the old version of the file can be recovered, rather than the file ending up corrupted.
