## Grow non-LVM ext4 partition
|
|
|
|
ATTENTION: Please note that the partition to enlarge has to be the last one with
|
|
the free space after it.
|
|
|
|
SSH into the VM.
|
|
|
|
- run `lsblk` check if the disk size has changed
|
|
- if not `reboot` the virtual machine
|
|
|
|
In the following it is assumed that the partition to enlarge is `/dev/sda2`
|
|
|
|
- change the size of the partition with `parted /dev/sda`
|
|
- inside of parted run `print free` and check where the free space after your
|
|
partition ends
|
|
- run `resizepart` and follow the instructions; End is the number you checked in
|
|
the last step
|
|
- `quit` parted
|
|
|
|
Now you need to resize the filesystem with `resize2fs /dev/sda2`.
|
|
|
|
## Error solving
|
|
|
|
### sudo: unable to open ... Read-only file system
|
|
|
|
Ususally the filesystem will go into read-only mode whe the system is running
|
|
and there is a consistency error.
|
|
To fix it run:
|
|
|
|
- `sudo fsck -Af -M` - check all filesystems
|
|
If `fsck` gets stuck after its version banner:
|
|
`fsck from util-linux 2.20.1`
|
|
you may want to try using the ext4-specific fsck:
|
|
- `fsck.ext4 -f /dev/sda1`
