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
