We have 3U systems with 3Ware raid controllers configured to give us large 11TB logical drives. The diskinfo command shows this:
# diskinfo -v da1 da1 512 # sectorsize 11999933104128 # mediasize in bytes (11T) 23437369344 # mediasize in sectors 1458908 # Cylinders according to firmware. 255 # Heads according to firmware. 63 # Sectors according to firmware. Y08210901E792700BAB9 # Disk ident. We want to create a BSD slice to cover the entire drive. My plan was to use the fdisk -I option: # fdisk -I da1 ******* Working on device /dev/da1 ******* fdisk: Class not found # fdisk -p da1 # /dev/da1 g c1458908 h255 s63 p 1 0xa5 63 1962532467 a 1 but as you can see, the partition size that this creates is only 1TB (1962532467*512=1004816623104 bytes). The fdisk command clearly knows how large the disk really is: # fdisk da1 ******* Working on device /dev/da1 ******* parameters extracted from in-core disklabel are: cylinders=1458908 heads=255 sectors/track=63 (16065 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=1458908 heads=255 sectors/track=63 (16065 blks/cyl) If I compute 1458908*255*63*512 this gives me 11999926794240, which is the correct size. But the -I option doesn't create a full sized partition. How do we resolve this? We want a full size partition spanning the entire disk, and we need a scriptable solution since the configuration of these servers is handled through an automated process. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
