Who used virtual file systems?

Question

Hard disks

The task is to organize an archive on Debian (saving video files),
there are several 3 TB hard drives, their number will increase.
It is necessary that from the locale they can be seen as one folder in ridonly mode. How best to implement the idea? mhddfs? virtyalfs?

Answer 1

I drove virtual fs, they work like shit, I organized a ball of video files on it, as a result, constant problems.
It’s easier to do each disk separately, or somehow split the folder and then mount everything into one folder through symlinks

Answer 2

zfs will save the father of Russian democracy. The current must be understood that if you want reliability, then you need to do zmirror, and you need to add disks to the pool in pairs of the same size.

Answer 3

First we read about LVM, then about SMB. And we are not trying to invent a bicycle and produce entities.

Answer 4

LVM - it is alarming that they write that if one disk fails, the volume is completely lost
