I have read this post and it is very good but it mentions alignment of the partitions using special CHS values and LVM/ext4 options. My partitions and both LUKS/LVM are aligned properly (at least i think they are). I am worried about the alignment of RAID itself. 2010/1/4 David Rees : > On Mon, Jan 4, 2010 at 11:30 AM, Khelben Blackstaff > wrote: >> Is there a way to make the RAID data start at a particular offset ? >> (In my case 512 sectors) ? > > http://thunk.org/tytso/blog/2009/02/20/aligning-filesystems-to-an-ssds-erase-block-size/ > > May have to tweak your fdisk parameters a bit. > > Don't worry about aligning your /boot partition since you don't > read/write from that much. > > -Dave >
