I recently resized a VPS from a 50GB SSD to a 300GB SSD through my hoster's control panel. I now am trying to resize my main partition with fdisk to be able to use all the new space. However, fdisk gives me a warning upon starting:
GPT PMBR size mismatch (104857599 != 629145599) will be corrected by w(rite). GPT PMBR size mismatch (104857599 != 629145599) will be corrected by w(rite).
It seems obvious that it's a sixfold of the previous size, as I went from 50GB to 300GB. So, I decide to follow the hint and write the table...
Command (m for help): w GPT PMBR size mismatch (104857599 != 629145599) will be corrected by w(rite). fdisk: failed to write disklabel: Invalid argument
.. which does not work. I can't find what causes that error anywhere despite many search queries. I do not use LVM and my partition table looks like:
Disk /dev/vda: 300 GiB, 322122547200 bytes, 629145600 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 30D92031-0C13-42FF-AC16-D34F36DD3907 Device Start End Sectors Size Type /dev/vda1 2048 32767 30720 15M BIOS boot /dev/vda2 32768 16809983 16777216 8G Linux swap /dev/vda3 16809984 104857566 88047583 42G Linux filesystem
Notice how the disk shows it as 300GiB, so it does recognize the size change.
