Estou executando o Ubuntu 11.04 (kernel 2.6.38-11). Troquei 2x160GB por unidades de 2x500GB. Eles estão configurados como RAID1.
As tabelas de partição mostram os tamanhos corretos. Aqui está o 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
E fdisk:
# fdisk -l /dev/sdb

Eu tentei mdadm e 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!
Alguma ideia?

Comentar por e-mail:
o problema está nos metadados, você só precisa montar o array raid com o parâmetro --update devicesize
e depois disso -G / dev / md? -z max fará o trabalho :)
sfdisk
você diz (?) ... Você quer dizer dizendo que também copiou o esquema de particionamento de disco?
cat /proc/mdstat
? Que talcat /proc/partitions
?
