So, question: can I force to map the drives with fixed path? I tried using Labels but it didn't seem to work.
Use o UUID:
$ ls -lF /dev/disk/by-uuid/
total 0
lrwxrwxrwx 1 root root 10 Sep 15 15:35 61965e0c-8aba-4207-9424-1350aa6e051e -> ../../sda2
lrwxrwxrwx 1 root root 10 Sep 15 15:35 e002a7bc-02da-47a8-ab98-1225e6ace6d5 -> ../../sda1
lrwxrwxrwx 1 root root 10 Sep 15 15:35 e23cc6c4-0e57-4cbd-8036-91ea9974bab0 -> ../../sda5
# blkid
/dev/sda5: LABEL="/data" UUID="e23cc6c4-0e57-4cbd-8036-91ea9974bab0" TYPE="ext3"
/dev/sda3: LABEL="SWAP-sda3" TYPE="swap"
/dev/sda2: LABEL="/" UUID="61965e0c-8aba-4207-9424-1350aa6e051e" TYPE="ext3"
/dev/sda1: LABEL="/boot" UUID="e002a7bc-02da-47a8-ab98-1225e6ace6d5" TYPE="ext3"
e altere seu /etc/fstab
para usar o nome persistente:
UUID=e23cc6c4-0e57-4cbd-8036-91ea9974bab0 /data ext3 defaults 1 2
