Which filesystem to use?

    • Which filesystem to use?

      Hey fellows,

      some time ago I was usinf OMV with ext (think it was 4, can'T remember). But when I crashed my OS I was unable to recover files by another linux system. So I had to use a backup of the OS to recover all my data.
      To avoid this, I'd like to know which filesystem is recommended on OMV3 right now.
      I'd prefer NTFS or exFat, as Windows supports this out of the box. But I've read it might slow down OMV.
      So is there any filesystem that's supportet by OMV, and Windows natively?

      Or shall I use ext4 and install ext4 drivers on Windows 10 in case of me crashing my OS, again? ;)
    • That is very strange that another linux system couldn't read an ext4 partition unless it was part of a raid array that wouldn't start. ext4 is the default filesystem. I wouldn't trust using Windows to read a Linux filesystem.

    • no file system will help if your raid crushes, unless it is a raid1 or raid 10 setup , than you can still start up raid in degrade mode using what ever usable drive(s) you have left.
      any other raid-levels are tricky or impossible to recover.

    • Typically I say xfs if most files are large and ext4 otherwise. If you don't have battery backup (UPS), don't use xfs.

    • Thanks for your advice.
      Whats the size-border between small and big?
      I'd like to share my whole music library (MP3) for all my devices (tablet, notebook, phone) as well as bigger video files and small documents as source codes and office documents.

      Building a UPS would be a nice weekendproject ;)
      I'm just collecting LiPos for another project - so that wouldn't be a problem!
    • There is no border. It is just a general statement. Both filesystems work well. You can't go wrong with ext4.

    • The overall features and support for Ext4 filesystem makes it the logical choice. Ext4 has many benfits over exFAY and ntfs, journaling alone makes it more robust. If you have another linux system for recovery anyway, I dont really see why you need to investigate M$ filesystems.
    • No one suggested a Microsoft filesystem and I would vote against using them. The question was which one to use between xfs and ext4.

      NO. From what I have read in various places, it needs to be re-written.
