mk2efs ext3 block count differs on same partition size
 

Hi

I've 2 ata disk which are equal (Maxtor DiamondMax Plus 9 120M) which have same C/H/S in linux (even I have to boot one with explicitly CHS if not one has 10011/255/64, 39420/16/255).
They have exactly the same partitions, but if I create a ext 3 fs df doesn't report the same
size (124 blocks differences of 1024k). If I see at the superblock (tune2fs -l fs) block count differs 31 blocks of 2094 which is exactly this difference and Reserved block count differs 2 block. Why this?

I want to use raid level 1 with md driver and my system freeze by copy large files.

Any idea?

Thanks

They could have been formatted slighty different perhaps. When I create a raid array and need to copy the partitions to be exact from one drive to the other, I always do a:

/sbin/sfdisk /dev/hdX -f /dev/hdX

Where the X is the corresponding drive.. the first one is the source drive, second one is the drive I want the partition layout copied to..
