fdisk não está vendo resize2fs encolhendo partição desmontada

0

Eu preciso fazer outra partição (/ dev / vda2) em um disco existente (/ dev / vda, 20G).

umount /mnt/
resize2fs /dev/vda1 10G
df -h

...
/dev/vda1       9.8G  7.8G  1.5G  85% /mnt

Então está tudo bem, mas não para o fdisk:

 fdisk -l /dev/vda
Disk /dev/vda: 20 GiB, 21474836480 bytes, 41943040 sectors
Units: sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: XXX

Device     Start      End  Sectors Size Type

/dev/vda15  2048     4095     2048   1M BIOS boot

/ dev / vda1 ainda é visto como 20G.

No entanto, o tune2fs está correto:

 tune2fs -l /dev/vda1

contagem de blocos * o tamanho do bloco é 10G, então o que acontece com o fdisk? Como eu poderia particionar os 10G restantes?

Você precisa excluir a partição e criar uma nova.

Escreva as alterações com a opção w quando tiver certeza de que elas estão corretas.
