J'ai exécuté Ubuntu 11.04 (noyau 2.6.38-11). J'ai remplacé 2x160 Go par des disques 2x500 Go. Ils sont configurés en RAID1.
Les tables de partition affichent les bonnes tailles. Voici sfdisk:
# sfdisk -d /dev/sdb
# partition table of /dev/sdb
unit: sectors
/dev/sdb1 : start= 63, size= 192717, Id=fd, bootable
/dev/sdb2 : start= 192780, size= 7807590, Id=fd
/dev/sdb3 : start= 8000370, size=968767695, Id=fd
/dev/sdb4 : start= 0, size= 0, Id= 0
Et fdisk:
# fdisk -l /dev/sdb
Disk /dev/sdb: 500.1 GB, 500107862016 bytes

J'ai essayé mdadm et resize2fs:
# mdadm --grow /dev/md2 --size=max
mdadm: component size of /dev/md2 has been set to 152247936K
# resize2fs /dev/md2
resize2fs 1.41.14 (22-Dec-2010)
The filesystem is already 38061984 blocks long. Nothing to do!
Des idées?

Commentaire par e-mail:
le problème est dans les métadonnées, il vous suffit d'assembler le tableau de raid avec le paramètre --update devicesize
et après -G / dev / md? -z max fera le travail :)
sfdisk
vous dites (?)… Voulez-vous dire en disant que vous avez également copié le schéma de partitionnement du disque?
cat /proc/mdstat
? Et alorscat /proc/partitions
?
