Eu tenho um servidor CentOS com dois discos de 1 TB. No entanto, é mal particionado.
Por favor, verifique abaixo:

Quando eu corri df
:
[root@p16282558 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md1 4.0G 4.0G 0 100% /
/dev/mapper/vg00-usr 4.0G 1.5G 2.4G 38% /usr
/dev/mapper/vg00-var 4.0G 880M 2.9G 23% /var
/dev/mapper/vg00-home
4.0G 136M 3.7G 4% /home
none 7.9G 556K 7.9G 1% /tmp
/opt
está dentro de /
e não há mais espaço em /
Meu /etc/fstab
é assim:
/dev/md1 / ext3 defaults 1 1
/dev/sda2 none swap sw
/dev/sdb2 none swap sw
/dev/vg00/usr /usr ext4 defaults 0 2
/dev/vg00/var /var ext4 defaults,usrquota 0 2
/dev/vg00/home /home ext4 defaults,usrquota 0 2
devpts /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /tmp tmpfs defaults 0 0
Portanto, há um disco md1
completo e um disco não utilizado /dev/md3
com 993.8 GB livres ??
Mas,
[root@p16282558 ~]# df -h /dev/md3
Filesystem Size Used Avail Use% Mounted on
- 7.9G 204K 7.9G 1% /dev
Isso significa que /dev
não está sendo montado no início do sistema (como por fstab)?
Output of vgdisplay:

Total PE 236931

Meu problema é: /opt
deve ser montado em um disco / partição com mais espaço.
Como posso reestruturar o disco para utilizar todo o espaço em disco de maneira eficiente?
