VM does not reclaim null blocks
Hello, I have a question regarding vSAN reclaim.
The environment is a CentOS8 VM running on vSAN RAID Level 5.
For disk 1, 40GB of space was allocated to install the OS, and 2TB of Disk 2 was configured as a DATA storage.
Disk 2 consists of a single partition of sdb1, and if you check with “df -h” command, 70GB of space is being used.
Based on vSAN RAID Level 5, it is calculated as 70G * 1.33, so it is expected to use about 93GB of space, but the disk uses about 262GB of VMDK capacity.
So I changed the VMDK’s policy to RAID Level 1, and then reverted it back to the RAID Level 5 policy.
After doing this, the capacity of Disk 2 was reduced to 202GB.
With a question, I cloned the VM and performed the same operation, and the disk capacity of the cloned VM was 129GB.
Could you tell us an example of a situation similar to this one and a solution?
