[Openstack] Resize root partition in VM Openstack
Guide Resize Mounted Volume in VM Openstack
Eventually we need to resize volume root /dev/sda, which is the root partition; the problem is root partition cannot detach, so how we can resize the size of the root partition? Here’s your answer dude
Resize From OpenStack Side
## set the status to available to a volume
openstack volume set --state available {volume id}
## resize the volume
openstack volume set --size 40 {volume id}
## check size and status again
openstack volume show {volume id}
## set status to in-use again
openstack volume set --state in-use {volume id}
Resize Volume from VM Side
## Grow part (Contoh akan resize root partisi)
sudo growpart /dev/vda 1
## Check apakah sudah grow sesuai volume baru
lsblk
## Resize ‘/’ partition to fill all space
sudo resize2fs /dev/vda1
## (option) If your filesystem is XFS, it can be grown while mounted using the xfs_growfs command:
sudo xfs_growfs /
## Verify
sudo df -H
if no space left on the block device, running command:
$ sudo mount -o size=10M,rw,nodev,nosuid -t tmpfs tmpfs /tmp
After the process unmount /tmp
sudo umount /tmp
IF LVM Volume :
1. Refresh LVM VG (LVM from lsblk)
vgchange --refresh
2. Resize pv
pvresize /dev/sdX
3. Extend lv
lvextend -l +100%FREE /dev/<vg_name>/<lv_name>
4. Mount /dev//
mount /dev/<vg_name>/<lv_name> /mnt
5. Filesystem grow
- Jika filesystem XFS
xfs_growfs /dev/<vg_name>/<lv_name>
- Jika filesystem . . . . Lanjutkan
```
