Yes, I use GPT since the MBR is limited to 32bits for #sectors of the partition table. I guess that my uncertainty about FFSv1 vs FFSv2 comes partly from this confusion between fdisk(8) vs gpt(8) and the 32bits limit and the mention of > 1To in newfs(8) man page. But if somebody had numbers about tests comparing FFSv1 and FFSv2 and the efficiency (for formatting, yes; but one formats only once; more efficient for reading? For writing? More space for data and less for metadata? Etc.)... -- Thierry Laronde <tlaronde +AT+ polynum +dot+ com> http://www.kergis.com/ http://www.sbfa.fr/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C
