I attempted a clean upgrade (meaning, during GUI anaconda told it to mkfs
all existing partitions) of a system running RH 7.1. When I did this, I
was told by the installer that:
"Partition 1 isn't aligned to cylinder boundaries. Need to add support for
and then the installer quit.
This is quite bizarre, since the same partition table had happily installed
At any rate, it looks like the 7.2 betas are seeing disk layouts
differently than 7.1, and that there's possibly been a loss of
functionality from 7.1 (but maybe not, since I don't think 7.1 would do
non-aligned partitions either?).
I finally had to zero the existing partition table and re-create partitions
to get the install to proceed. If I'd been doing a traditional upgrade
from 7.1 (meaning, just convert ext2 -> ext3 rather than mkfs) I'd have
Its unfortunate you erased the partition table - is there anyway of recreating
it? Otherwise there is little we can do with this bug report.
I have not heard any other cases of this occurring, so it would be nice if you
could reproduce it.
Here are the old cylinder boundaries, which I'd actually written down (sorry, I
don't have a full dump of that partition table, but maybe this is better than

This defect is considered SHOULD-FIX for Fairfax.
We would really need to see the C/H/S start and end of each partition. Thanks
for the additional information anyways.
Jermemy - would you try purposely making a bad partition table (try changing the
number of heads/cyl/sectors in fdisk expert mode) and see if this message appears?
If you set the C/H/S on the drive to 16 heads, 63 sectors, 89355 cylinders
and use the above original boundaries, it should recreate the original setup
this message came from the pc98 support, which is now disabled. This case
should be working again with rc2 and later.
