When swap partitions are created with fdisk, there's a "t" option that
is used to set the partition type. If swap partitions are created with
mkpart in parted, the "FS-TYPE" can be included in the command. I'll bet
if you change the scriplet to create the swap partitions with the Linux
swap partition type, the boot software will then see the type and know to
do the right thing.

Hi,
We're deploying our nodes using pre-exec scriptlets, in which we do our own
partitioning.
In this scriptlets, we have things like that :
1- Create swap paritions
2- "mkswap those partitions"
The issue is the following : until now, everything was working fine.
With SL5.8, at reboot, our nodes only have 2GB of swap enabled per swap
partition.
If we do:
- swapoff partition
- mkswap partition
- swapon partition
Then the swap size appears to be what it should be (up to 128GB depending on
the node, so 2GB clearly is a not a good thing for us).
Off course, we could work around this using several methods, but that would be
work arounds only.
I tried installing a node using anaconda's partitioning and no pre-exec scripts
: then the swap is correctly defined/used.
Finally, I noted that on the failing systems (pre-exec partitioning), the
partition type is 83 (linux), while on the anaconda-made
swap, partition type is 8e (Linux swap / Solaris)
Bug or not a bug ?
Thanks
