Change the data disk size and performance

[tbolon]

The current disk is 128GiB in size, in a premium performance tier (P10 - 500 IOPS, 100 MBps)

The metrics show that the drive is mostly idle, but the growth is problematic.

I think we could move to a lower tier performance level with more capacity (Standard SSD E15 - 256GiB) for the same or less amount.

It seems this change will require a reboot of the VM, so must me planified.

Started migrating the data disk

Ok, migration done. I had to use xfs_growfs manually since the guide at https://learn.microsoft.com/en-us/azure/virtual-machines/linux/expand-disks?tabs=ubuntu#increase-the-size-of-the-os-disk supposed that the partition was increased automatically (it was not the case here).
