How to increase size of root partition at /dev/sda1 from /dev/sdb1?
0
I have an Ubuntu 16.04 system without GUI (only command line) with a very limited root partition (20GB) and 1 storage partition (1000GB) as below
sudo parted -l
Model: QEMU QEMU HARDDISK (scsi)
Disk /dev/sda: 21.5GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 21.5GB 21.5GB primary ext4 boot
Model: QEMU QEMU HARDDISK (scsi)
Disk /dev/sdb: 1074GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 1074GB 1074GB primary ext4
The current status of these disk are:
df -hP
Filesystem Size Used Avail Use% Mounted on
udev 27G 0 27G 0% /dev
tmpfs 5.4G 530M 4.9G 10% /run
/dev/sda1 20G 19G 194M 99% / (almost full!!!!!)
tmpfs 27G 112K 27G 1% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 27G 0 27G 0% /sys/fs/cgroup
/dev/sdb1 985G 602G 333G 65% /rasv1 (more space!!!!!)
tmpfs 5.4G 20K 5.4G 1% /run/user/121
tmpfs 5.4G 0 5.4G 0% /run/user/1001
How can I increase the size of root partition for /dev/sda1 (e.g: 20GB -> 100 GB) from /dev/sdb2 (1000GB -> 900GB) online (no liveCD, USB boot, reboot)?

Unless you are using LVM, or zfs (or a few others) I don't think you could borrow for /sdb to feed /sda. But this is a VM - why not make the virtual disk /sda bigger, and expand the file system for it? And make a live USB while you are at this.

@CharlesGreen thanks, but I only have access to this VM, so seem like no other choice for me.

OK - summarizing, you have no physical access, the VM administrator will not increase your /sda (this would have to be offline anyhow) and you are space limited. I'm going to vote for re-open, and ask a few questions - please append the results into your original question!

20 GB should be enough under most circumstances - the commands I wrote are useful in finding out where all the space is being used up.
