Don’t extend current vmdk or add a vmdk greater than 2TB – vROps

As the title implies, if you need to extend your vROps instance’s disk, ensure you stay below the 2TB limit per vmdk. The MBR format limits you to 2TB, if for whatever reason you need to extend a vmdk beyond this limit you may be able to use gparted or similar tool to convert the partition table to the GPT format and go from there. However I haven’t tested this and don’t know if VMware support changing table formats.

Here’s the error I got a few days ago:

Error: partition length of 6442448896 sectors exceeds the msdos-partition-table-imposed maximum of 4294967295
