EC2 Can't resize volume after increasing size
amazon-ec2, centos, image-resizing, snapshot, volume
Solution
Thank you Wilman your commands worked correctly, small improvement need to be considered if we are increasing EBSs into larger sizes
- Stop the instance
- Create a snapshot from the volume
- Create a new volume based on the snapshot increasing the size
- Check and remember the current's volume mount point (i.e. `/dev/sda1`)
- Detach current volume
- Attach the recently created volume to the instance, setting the exact mount point
- Restart the instance
Access via SSH to the instance and run `fdisk /dev/xvde`
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u')
Hit p to show current partitions
- Hit d to delete current partitions (if there are more than one, you have to delete one at a time) NOTE: Don't worry data is not lost
- Hit n to create a new partition
- Hit p to set it as primary
- Hit 1 to set the first cylinder
- Set the desired new space (if empty the whole space is reserved)
- Hit a to make it bootable
- Hit 1 and w to write changes
- Reboot instance OR use `partprobe` (from the `parted` package) to tell the kernel about the new partition table
- Log via SSH and run resize2fs /dev/xvde1
- Finally check the new space running df -h
Problem
I have followed the steps for resizing an EC2 volume - Stopped the instance - Took a snapshot of the current volume - Created a new volume out of the previous snapshot with a bigger size in the same region - Deattached the old volume from the instance - Attached the new volume to the instance at the same mount point Old volume was 5GB and the one I created is 100GB Now, when i restart the instance and run `df -h I` still see this ``` Filesystem Size Used Avail Use% Mounted on /dev/xvde1 4.7G 3.5G 1021M 78% / tmpfs 296M 0 296M 0% /dev/shm ``` This is what I get when running ``` sudo resize2fs /dev/xvde1 The filesystem is already 1247037 blocks long. Nothing to do! ``` If I run `cat /proc/partitions` I see ``` 202 64 104857600 xvde 202 65 4988151 xvde1 202 66 249007 xvde2 ``` From what I understand if I have followed the right steps xvde should have the same data as xvde1 but I don't know how to use it How can I use the new volume or umount xvde1 and mount xvde instead? I cannot understand what I am doing wrong I also tried `sudo ifs_growfs /dev/xvde1` ``` xfs_growfs: /dev/xvde1 is not a mounted XFS filesystem ``` By the way, this a linux box with centos 6.2 x86_64
