I'm having an issue with expanding one of my VMWare datastores. I'm posting here because I've worked with VMWare for a very long time, along with EqualLogic, Compellent, Powervault, Promise and a few other storage arrays. When you expand a LUN on the storage device, you then go back to VMWare and at most, you would have to rescan storage for it to register, and you can then expand the volume.
That doesn't seem to be happening here with FreeNAS. I just finished migrating over to 11 disk RAIDZ3 volume, and replacing the remaining 4TB SAS disks with 8TB Helium SAS disks. FreeNAS then expanded the volume as expected once the last 4TB disk had been replaced with the 8TB disk. I then increased the size of the zvol from 16T to 24T (and please forgive me for 'incorrect terminology' - I'm using the terminology that lines up with the FreeNAS UI). This is reflected under 'Storage', and if I go to Sharing > block > Extents and edit the extent to view what it shows, it too reflects that the device extent is now 24T.
No matter what I do (I've rescanned storage and rebooted my hosts), VMWare is still showing 16T as the LUN size - it seems as if FreeNAS is still presenting it to VMWare as 16T. Am I missing something in FreeNAS? Or does it take a while for this change to make it into iSCSI and become visible to the VMWare hosts?
