Redimensionamento de Filesystem...

RED HAT 4/3/2/1

1) Verificar se tem o jfs2 online:

[root@BACKUP]# rpm -qa |grep lvm
lvm2-2.02.06-6.0.RHEL4
system-config-lvm-1.0.19-1.0

2) Verificar a qual vg o FS esta atrelado:

[root@BACKUP]# df -k .
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/rootvg-lvol1
22657532 20437020 1990364 92% /BACKUP

3) Verificar se o VG possui espaço.

[root@~]# vgdisplay rootvg |grep "Free"
Free PE / Size 36 / 1.12 GB

No caso, existe 1.12Gb livres.

3) Verificar o caminho correto do lvol:

4) Aumentando 1 Gb :

[root@BACKUP]# lvextend -L +1000M /dev/rootvg/lvol1
Extending logical volume lvol1 to 21.95 GB
Logical volume lvol1 successfully resized

5) Validando o aumento

[root@BACKUP]# ext2online /BACKUP
ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b
