Hi
I am having trouble at the partitioning stage of install.sh, the partitions are
not created the size I ask for. I have tried variouscombinations of the env
vars, and command line args.
# TASKS="ALL" QI=true ./install.sh --part1-size 4000 --swap-size 256 partition
gives:
Disk /dev/mmcblk0: 8166 MB, 8166309888 bytes
4 heads, 16 sectors/track, 249216 cylinders, total 15949824 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
Disk identifier: 0x2940d389
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 2048 241404 119678+ 83 Linux
/dev/mmcblk0p2 241405 15949823 7854209+ 82 Linux swap /
Solaris
a ~100 MB /dev/mmcblk0p1 and 7GB /dev/mmcblk0p2 for swap.
install.sh calculates the size of the first partition in cyclinders, by
subtracting the size of swap. It then uses the sizes in cylinders to create the
partitions.
SHR has fdisk (util-linux-ng 2.18), which defaults to working in sectors. so
fdisk asks for sectors, and install.sh replies in cylinders.
the quick fix on SHR seems to be to call fdisk with "fdisk /dev/mmcblk0
-u=cylinders", but this will probably give an error if you do it on other fdisks. I
could make a patch to to try to detect which fdisk is being used, and conditionally add
the flag.
it looks like in the future fdisk will use sectors, so the real solution is probably do
the calculations in sectors. The "-u" should make sure any fdisk version uses
sectors.
