Re: Raid0 max volume size
Hmmm On install of openbsd a second, non-boot 4 TB disk was initialized by fdisk in the usual way. My intention was to create a single partition and file system for the whole disk. However, disklabel limits me to a partition size of 2 TB. The c partition automatically covers the full disk, but I didn't think one could actually create a file system on the c partition. Is there something I am missing?
