[SOLVED] Redhat Increasing disk partition in linux

Redhat Increasing disk partition in linux

I have a disk in azure redhat. I increased the size from 128GB to 256 GB. I restarted it and mounted it again. It is gpt partion.For lsblk /dev/sdc1 is showing it already has 256 GB but df -h is showing 128GB.

lsblk /dev/sdc1
NAME MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sdc1   8:33   0  256G  0 part /datapoint

df -h
/dev/sdc1                  128G   41G   88G  32% /datapoint.

lsblk
sdc                 8:32   0  256G  0 disk 
└─sdc1              8:33   0  256G  0 part /datapoint

I tried to increase the partition with growpart growpart /dev/sdc 1. And I am having unable to extend partition with growpart - partition 1 could only be grown by 2046 error. Is there any way to increase the partition. Thanks. This is xfs file system.

Solution

You need to grow the filesystem according to the new partition size. growpart does not do this.

For XFS you use xfs_growfs to do the job on a mounted filesystem:

xfs_growfs -d /datapoint
