I have a server with 2TB (Raid, 2x2TB), and this partition schema / => /dev/md2 - 20GB /home => /dev/md3 - 1.8TB This is a ISPConfig server, so we need many space in /var and almost nothing into /home, so i think that the best way to do this is put /home in /dev/md2 and /var into /dev/md3 My fstab is this: # <file system> <mount point> <type> <options> <dump> <pass> /dev/md2 / ext4 errors=remount-ro 0 1 /dev/md3 /home ext4 defaults 1 2 /dev/sda4 swap swap defaults 0 0 /dev/sdb4 swap swap defaults 0 0 Which is the best way to do this? I think move /home contents to /homeold, remove from fstab, umount and now copy from /homeold to /home, and then change /var name (i dont have enough space to do the copy), mount new /var and move content, is this correct? Also, i need to stop all server services to avoid errors (mysql, apache, mongodb, named, etc), any fast way to do this? Or maybe i should restart in rescue mode to do this? Maybe another way is a full change between / and /home, i mean, put / in /md3 and /home in md2, is this possible only by edit fstab and reboot? Thank you sou much,
