Hi
I create a 20GB droplet and create a snapshot then I realize that I will need more space so I did a permanent resize on the droplet to 40 GB but I made a mistake on the configuration and I restored the snapshot but when I check the space (df -h) its listed only 20 GB. I contacted the support of digitalocean and they told me that they can put the droplet on recovery and the I can change the size, but I wasn’t able to do it since the only information that I found this command sudo resize2fs /dev/vda1
but I wasn’t able to make it to work, can you help me to resolve this issue?
Regards

You’ve probably solved this problem by now, but I had a similar issue and solved it.
I created a droplet that was 20gb, then took a snapshot and created a new 30gb droplet from that snapshot. Running df -h
on the new droplet still showed 20gb.
Tech support linked me to this unanswered question (accidentally) and an article that contained information that mainly applied to resizing additional filesystems (ie, those without the OS), but the main command did the trick for me. Simply run the following command:
sudo resize2fs /dev/disk/by-label/DOROOT
Resize2fs is safe to use on live filesystems with an OS. Here is a note from the resize2fs manual page:
“If the filesystem is mounted, it can be used to expand the size of the mounted filesystem, assuming the kernel and the file system supports on-line resizing. (Modern Linux 2.6 kernels will support on-line resize for filesystems mounted using ext3 and ext4)”
Still, if you’re paranoid about data loss like me, and if you’ve made any changes since spinning up the new droplet, create a snapshot backup for yourself before running resize2fs.
In your specific case, I think the problem was that you were using the disk name instead of the volume name. The volume name and path is what appears when you run df -H
, which for me was:
Filesystem Size Used Avail Use% Mounted on
..
/dev/disk/by-label/DOROOT 22G 12G 10G 55% /
..
Whereas /dev/vda
was my disk name, as it appeared in parted
.
Hello there,
You can check our article on How to Resize Droplets
https://docs.digitalocean.com/products/droplets/how-to/resize/
In certain cases, a disk resize fails to resize the Droplet’s partition or filesystem. If you rerun df -h after a disk resize and the output is unchanged, this usually indicates a problem. Use gdisk
to get more information:
- gdisk -l /dev/vda
The output looks like this:
GPT fdisk (gdisk) version 1.0.3
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Disk /dev/vda: 104857600 sectors, 50.0 GiB
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): C1E73477-225B-4585-8BB5-C9291E473CE4
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 52428766
Partitions will be aligned on 2048-sector boundaries
Total free space is 2014 sectors (1007.0 KiB)
Number Start (sector) End (sector) Size Code Name
1 227328 52428766 24.9 GiB 8300
Some operating systems, like CentOS, don’t come with gdisk by default. You can either install gdisk
using the package manager (e.g. sudo yum install gdisk) or use fdisk:
- fdisk -l /dev/vda
The output looks like this:
Disk /dev/vda: 50.0 GB, 53687091200 bytes, 104857600 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000b956b
Device Boot Start End Blocks Id System
/dev/vda1 * 2048 52428766 52426718 83 Linux
In both of the above cases, the partition is still 25 GB even though the disk is 50 GB.To resize the partition, use the growpart
command. In this command, /dev/vda is the name of the disk, separated by a space, and followed by the number of the partition to resize, 1.
- growpart /dev/vda1
The command to resize the filesystem depends on the filesystem type. If you don’t know what filesystem you’re using, check with df:
- df -Th /dev/vda1
You can see the filesystem type in the second column of the output. The following example output shows the filesystem type is ext4.
Filesystem Type Size Used Avail Use% Mounted on
/dev/vda1 ext4 50G 4.0G 45G 10% /
For ext3/4 filesystems, use resize2fs
to resize the filesystem.
- resize2fs /dev/vda1
For XFS, use xfs_growfs
to resize the filesystem.
- xfs_growfs /dev/vda1
