Raid 5 logiciel debian squeeze: problème lors de la création
Bonjour,
je souhaite monter un raid5 sous debian squeeze:
j'ai formaté mes disques dur comme ceci:
root@debian-serveur:~# fdisk -l /dev/sdb
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00026ffb
Device Boot Start End Blocks Id System
/dev/sdb1 1 121602 976762552 fd Linux raid autodetect
root@debian-serveur:~# fdisk -l /dev/sdc
Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00029e62
Device Boot Start End Blocks Id System
/dev/sdc2 1 121602 976762552 fd Linux raid autodetect
root@debian-serveur:~# fdisk -l /dev/sdd
Disk /dev/sdd: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0002c2be
Device Boot Start End Blocks Id System
/dev/sdd3 1 121602 976762552 fd Linux raid autodetect
root@debian-serveur:~# fdisk -l /dev/sde
Disk /dev/sde: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0002e391
Device Boot Start End Blocks Id System
/dev/sde4 1 121602 976762552 fd Linux raid autodetect
ensuite:
mdadm --create /dev/md0 --level 5 --raid-devices=4 --spare-devices=0
/dev/sdb1 /dev/sdc2 /dev/sdd3 /dev/sde4
et je fais:
root@debian-serveur:~# cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md127 : active raid5 sdb1[0] sde4[4] sdd3[2] sdc2[1]
2930284032 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/3] [UUU_]
[>....................] recovery = 4.1% (40082372/976761344)
finish=220.6min speed=70737K/sec
Le soucis est que ma grappe à 4 disque or: algorithm 2 [4/3] [UUU_]
--> il manque un U
Si je crée le RAID 5 pendant l'installation de Debian j'ai pas de
soucis. Par contre j'ai un problème vu que les disques dur que j'ai
ont un soucis: cf ce lien

Une idée? merci
