I want to learn more about file systems from the practical point of view so I know what to expect, how to approach them and what experience positive or negative you had / have.
I found this wikipedia’s comparison but I want your hands-on views.
For now my mental list is
- NTFS - for some reason TVs on USB love these and also Windows + Linux can read and write this
- Ext4 - solid fs with journaling but Linux specific
- Btrfs - some modern fs with snapshot capability, Linux specific
- xfs - servers really like these as they are performant, Linux specific
- FAT32 - limited but recognizable everywhere
- exFAT - like FAT32 but less recognizable and less limited
Interesting choice for NAS, why not the others that seem like better alternatives?
Well, as far as I know, BTRFS and ZFS are the recommended file systems for NAS’s. They have self-healing capabilities so I can be slightly more sure that my data does not get corrupted over time.
Is self-healing process automated or you need to somehow enable it so it happens from time to time?
You have to run a so-called
scrub
command that checks for errors and tries to repair them. You can automate to run it every month or soIn a cronjob or something alike?
Yup
