I'm trying to solve a problem where my computer locks up every few
minutes for a minute or so. I thought possibly it might be related to
the SSD that has my / partition since I haven't been able to find any
program that is doing it. Top and IOTop don't show any unusual activity.
This led me into partitioning. I thought that GPT pretty much gave you
proper partition alignment, but now I think I was mistaken on that
point. gdisk shows my first partition starting at 34, with the fdisk
info showing 255 heads, 63 sectors/track. That doesn't come close to 4k
alignment.
There is a linux mag article (http://www.linux-mag.com/id/8397/) that
talks a lot about this, and seems to like using cylinder alignment
instead of just starting the partition on a sector that is 8*512.
Anyway, my gdisk data is:
Disk /dev/sda: 234441648 sectors, 111.8 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): ****************
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 234441614
Partitions will be aligned on 1-sector boundaries
Total free space is 0 sectors (0 bytes)
Number Start (sector) End (sector) Size Code Name
1 34 232542884 110.9 GiB 8300 Linux
filesystem
2 232542885 234441614 927.1 MiB EF02 BIOS boot
partition
Before I haul out sysrescuecd and move my partitions around, I thought
I'd ask for suggestions. Should I move the filesystem to something that
is a multiple of 8, do something else, or look elsewhere for a solution
to my problem?
