How to append free space from LVM volume?

  • 772

I am running out of space on a LVM volume and am wondering where 10G are allocated:

df -h
/dev/mapper/vg0-staging   20G   19G  177M 100% /mnt/staging

lvs
staging vg0  -wi-ao----  30.00g

Is there a way to append the free space and increase the partition to the full size of the volume while keeping the data intact?

    You have to resize the filesystem inside vg0/staging volume:

    • if it is an XFS filesystem, you can resize it with xfs_growfs /mnt/staging
    • if it is an EXT4 filesystem, you can resize it with resize2fs /dev/mapper/vg0-staging
