Zmieniające się dyski - raid
Redhead - 30-06-2009 10:26
Witam.
Problem ogólnie znany, tylko że u mnie jest trochę inna sytuacja.
Chodzi o ze po restarcie (nie po każdym) przykładowy dysk zamiast być /dev/sdd1 jest /dev/sdc1.
Myślałem że można by użyć UUID w /etc/fstab, ale...
Ta sytuacja chyba się nie sprawdzi, bo dyski są w macierzy

Jak zatem to łatwo zrobić? Bo każdym restarcie tak jakby macierz wymagała naprawy, chociaż wszystko będzie poprawnie, jak się zrestartuje komputer.

Dodam że w /etc/mdadm/mdadm.conf mam tylko wpis:
DEVICE partitions
#### /dev/md0 >> raid5
#DEVICE /dev/sd[bcdfg]1
#ARRAY /dev/md0 devices=/dev/sdb1,/dev/sdc1,/dev/sdd1,/dev/sdf1,/dev/sdg1
[Dodano: 2009-06-30, 11:32]
Czy nie można by dodać może UUID w /etc/mdadm/mdadm.conf?
Tylko że sytuacja z UUID wygląda trochę śmiesznie:
# blkid /dev/sd[bcdef]1
/dev/sdb1: UUID="b01be760-596e-2208-6b66-30c2a0eb0351" TYPE="mdraid"
/dev/sdc1: UUID="b01be760-596e-2208-6b66-30c2a0eb0351" TYPE="mdraid"
/dev/sdd1: UUID="b01be760-596e-2208-6b66-30c2a0eb0351" TYPE="mdraid"
/dev/sde1: UUID="b01be760-596e-2208-6b66-30c2a0eb0351" TYPE="mdraid"
/dev/sdf1: UUID="b01be760-596e-2208-6b66-30c2a0eb0351" TYPE="mdraid"
A to wygląda bez sensu trochę, bo linia ARRAY miałaby w sobie 5 takich samych UUID.
#DEVICE /dev/sd[bcdfg]1
DEVICE partitions
ARRAY /dev/md0 num-devices=5 UUID=b01be760-596e-2208-6b66-30c2a0eb0351, b01be760-596e-2208-6b66-30c2a0eb0351, b01be760-596e-2208-6b66-30c2a0eb0351, b01be760-596e-2208-6b66-30c2a0eb0351, b01be760-596e-2208-6b66-30c2a0eb0351
Pozdrawiam.
