Question

linux

Increased the disk on the virtual machine from 11gb to 17gb

# df -h

# fdisk -l

Tried deleting /dev/sda4 and re-adding. But when informing the system about the change, it gives an error.

Command (m for help): d
Partition number (1-4, default 4): 4
Partition 4 is deleted

Command (m for help): n
Partition type:
p primary (3 primary, 0 extended, 1 free)
e extended
Select (default e): p Selected
partition 4 +size{K,M,G} (23068672-33554431, default 33554431): Default value 33554431 Partition 4 of type Linux and of size 5 GiB is set Command (m for reference): t Partition number (1-4 , default 4): Hex code (type L to list all codes): 8e Changed type of partition 'Linux' to 'Linux LVM' Command (m for reference): w The partition table has been changed!



Called ioctl() to reread the partition table.

WARNING: Re-reading the partition table failed with error 16: The device or resource is busy.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)

# partprobe
Error: Partition(s) 4 on /dev/sda have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes.

Answer 1

Disk label type: dos

You have a partition table on an MBR disk, it does not allow you to create more than 4 primary/extended partitions. Delete partition 4, create an extended one and create as much as you want in it.
Although, IMHO, it’s easier and better not to resize the disk, but to add a second virtual one and throw it entirely into lvm

Answer 2

Why add another section if you also want to add it to lvm? Just expand
parted resizepart + pvresize
