Raid levels. I have multiple HDD with different sizes, and need to add more hdds if needed.
- RAID 0 (striping) but losing any disk means losing all the data.
- RAID 1 (mirroring). All hdds should be identical.
- RAID 5 (parity striping) but requires at least 3 similar drives.

How to convert RAID 0 to RAID 5 without losing any data?
SMB works on Network tab in Ubuntu PCManFM
SSH
ssh admin@192.168.8.192
The folder structure is following:
NFS
Samba
Samba server works almost out of the box. Use
smbclient -L 192.168.8.192 -U admin
to see the folders and
smbclient //192.168.8.192/Public -U admin
to actually connect the server. The get command allows to download files to local computer.
Samba works on Thunar (or Nautilus) after installing gvfs, gvfs-smb and sshfs packages, see https://wiki.archlinux.org/title/Thunar#Using_Thunar_to_browse_remote_locations. Use smb://192.168.8.192 only.
