Hi I'm Jeff
I'm managing CentOS 6,7 Server. The server have a Filesystem. It's not a LVM(just normal filesystem of partition).
If I want to extend the Filesystem's size, I have to delete it and make it again. But I want to extend the size without data lose.
Is there anyway to do that ?

- How to extend Volume : VMWARE DataStore Volume Extend
- Qustion : After I extend volume, How to extend Partition's capacity?

Goal : /dev/sda2 sizing up! 76G -> 100G

Welcome any advice.

Thanks.

Reboot and the new size will be recognised. Not strictly required, but easiest/safest.
Then "man xfs_growfs".

The problem is that the sda3 swap partition immediately follows the 76G sda2 partition. You will need to delete the swap partition, then enlarge the sda2 partition and its xfs filesystem (leaving 4G for the swap partition), and create and format a new swap partition. Note that if your current /etc/fstab references the swap partition by its UUID or label, you should include that UUID or label when formatting the new swap partition. See the mkswap manpage for details.

Well spotted - makes one wish LVM was in the mix ...

Thanks your reply.

If that is not LVM, Is it possible to use xfs_growfs? I have another server and have same situation. That server has ext4 filesystem and It's not a LVM.
I just want to resize my filesystem(not LVM) without delete and recreate.

The xfs_growfs is not dependent on LVM - the problem is as stated in post #3; swap is in the way. You can only grow the filesystem if the partition is larger than the filesystem. However the partition must be contiguous space, not broken over segments.
resize2fs will similarly enlarge ext4 filesystems. See the manpage for both commands.

Thanks. I solved it. As you said, I deleted my swap partition and /dev/sda2. After then, I made a new partition(completed resizing).
Delete -> Make New Partition -> reboot -> resize2fs

I just worried about data lose but It didn't happen.
Good..

Good. Can you consider marking your thread as [SOLVED] then please?
