Which do you prefer and why for HDD or SDD hard disks ? And how is Ext4 with power failures nowadays ? iirc a few years ago there were issues with Ext3 (Yes, Ext3) and I remember a no barrier option was needed ? Is Ext4 much better ? And what FS do you prefer on usb storage ?
Here’s something different. I use several external USB drives with mergeFS + EXT4 to backup my file server (LVM + EXT4).
Cool, thanks for the mergerFS mention. Since this is packaged for Debian, and in Arch Linux AUR, I am eager to try this.
