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
That’s sound fantastic! Interesting that you didn’t mentiona anything about snapshots. Have you had some isshes with BTRFS since then?
Well, snapshots, too. I just consider them to be a special case of de-duplication.
I had an issue when I ran out of space during conversion between RAID profiles a few years back. I didn’t lose any data, but I couldn’t get the array to mount (and stay) read-write.
