We have a (older) Windows 2012 R2 VM with a OS Disk and a Data Disk (scsi.0 and scsi.1 respectively) running on AHV / AOS 188.8.131.52 LTS
The data disk (scsi.1) was originally created with 4kb allocation unit size (no NTFS disk compression is utilized) and this disk has reached it’s maximum size under NTFS of 16TiB.
It’s also 96% full… 😟
The custom application is such that mount points won’t work.
It was suggested to see if perhaps Acronis Disk Director could safely change the drive’s allocation unit size from 4k to 64k (and preserve the data). To my knowledge formatting a drive is the only way to accomplish allocation unit size changes...
Is changing the allocation unit a supported operation?
Has anyone successfully made such a change?
