Description

On new deployment, when adding two data disk. The RAID configuration is happening around 75% of the time correctly, although in the other 25% of the times we get the following error after partitioning.
The error is:

mkfs.ext4: Device size reported to be zero. Invalid partition specified, or
partition table wasn't reread after running fdisk, due to
a modified partition being busy and in use. You may need to reboot
to re-read your partition table.

Also after a reboot the problem exists.

Research direction

The report names no template, file, test, or entry point. Start by locating the deployment template that provisions two data disks and reviewing the partitioning and filesystem steps around the reported mkfs.ext4 error. Reproduce the deployment if possible and determine what makes the partition intermittently appear to have zero size; done means RAID configuration completes reliably without the error.
