 |
|
Hallo,
ich habe in einem Server 2 SATA-Platten, die über Software-RAID-1 verbunden sind und in 3 Partitionen aufgeteilt sind. Der Server läuft Tip Top, aber heute tipp ich zufällig mal
lsraid -a /dev/md0:
| Quote: | lsraid: Device "/dev/sda2" does not have a valid raid superblock
lsraid: Device "/dev/sdb2" does not have a valid raid superblock
[dev 9, 0] /dev/md0 00000000.00000000.00000000.00000000 online
[dev ?, ?] (unknown) 00000000.00000000.00000000.00000000 missing
[dev ?, ?] (unknown) 00000000.00000000.00000000.00000000 missing |
lsraid -a /dev/md1 genauso:
| Quote: | lsraid: Device "/dev/sda3" does not have a valid raid superblock
lsraid: Device "/dev/sdb3" does not have a valid raid superblock
[dev 9, 1] /dev/md1 00000000.00000000.00000000.00000000 online
[dev ?, ?] (unknown) 00000000.00000000.00000000.00000000 missing
[dev ?, ?] (unknown) 00000000.00000000.00000000.00000000 missing |
lsraid -a /dev/md2 aber nicht:
| Quote: | [dev 9, 2] /dev/md2 55A635B6.90DF659B.C60F68A6.7157CE32 online
[dev 8, 1] /dev/sda1 55A635B6.90DF659B.C60F68A6.7157CE32 good
[dev 8, 17] /dev/sdb1 55A635B6.90DF659B.C60F68A6.7157CE32 good |
In /proc/mdstat zeigt, dass alle Platten in Ordnung sind:
| Quote: | Personalities : [raid1] [faulty]
md2 : active raid1 sdb1[1] sda1[0]
23936 blocks [2/2] [UU]
md1 : active raid1 sdb3[1] sda3[0]
155284224 blocks [2/2] [UU]
md0 : active raid1 sdb2[1] sda2[0]
39070016 blocks [2/2] [UU]
unused devices: <none> |
MD0 (/) und MD1 (/home) sind ReiserFS, MD2 dagegen ist Ext3 (/boot).
Meine Fragen:
Woher kommt das?
Muss ich das beachten?
Wie kann ich das beheben?
Danke und frohe Ostern,
Klaus |

Hi,
auf was hast du den Partitionstyp von den an md0 und md1 beteiligten Partitionen gestellt?

sdb sieht identisch aus. |

Poste bitte deine /etc/mdadm.conf.

Ne /etc/mdadm hab ich nicht. Gibts die heutzutage noch, oder sollte es die geben? Die ist doch noch aus der 2.0er und 2.2er Zeit?
Ich kann nur die /etc/raidtab posten...
