Hello,

I have raid5 /dev/md1, --chunk=128 --metadata=1.1. On it I have
created LVM volume called 'raid5', and finally a logical volume
'backup'.

Then I formatted it with command:

   mkfs.ext3 -b 4096 -E stride=32 -E resize=550292480 /dev/raid5/backup

And because LVM is putting its own metadata on /dev/md1, the ext3
partition is shifted by some (unknown for me) amount of bytes from
the beginning of /dev/md1.

I was wondering, how big is the shift, and would it hurt the
performance/safety if the `ext3 stride=32` didn't align perfectly
with the physical stripes on HDD?

PS: the resize option is to make sure that I can grow this fs
in the future.

PSS: I looked in the archive but didn't find this question asked
before. I'm sorry if it really was asked.
