I've tried to create a Linux swap file, but when I run fdisk, it looks like this: Device Boot Start End Blocks Id System /dev/hdb1 * 1 3644 29270398+ 83 Linux /dev/hdb2 3645 3737 747022+ f W95 Ext'd (LBA) /dev/hdb5 3645 3737 746991 82 Linux swap Why is this W95 partition existing in the same place as my Linux swap? I would have thought they'd be incompatible. Can my Linux OS use this Linux swap? Does this need cleaning up, and if so how? Dave

DOS disklabels can only have 4 partitions (primary), so to get around that you can create a primary partition as type extended, which can contain more partitions (up to 12, I think). On my system, the extended partition is type 5, on yours it's type f. I'm not sure it's hurting anything, but to be on the safe side, I'd probably delete partitions 5 and 2, and just create a primary partition of type 82 (Linux swap). In a related note, does your system have no other swap enabled at all? That could explain your yum-lockup problems. Yum is very memory intensive, if you starve it and it has no swap to go to, it probably will lock up. :-) Matt -- Matt Hyclak Department of Mathematics Department of Social Work Ohio University (740) 593-1263 -------------- next part -------------- A non-text attachment was scrubbed...

It acts as a container for logical partitions (with a number greater than or equal to 5). -- Ignacio Vazquez-Abrams <ivazquez at ivazquez.net> http://centos.ivazquez.net/ gpg --keyserver hkp://subkeys.pgp.net --recv-key 38028b72 -------------- next part -------------- A non-text attachment was scrubbed...

Thank you for the advice. With a little tweaking, my partitions now look
like this:
Device Boot Start End Blocks Id System
/dev/hdb1 * 1 3644 29270398+ 83 Linux
/dev/hdb2 3645 3737 747022+ 82 Linux swap
Will Linux automatically start using that as a swap, or do I have to
do something to mount it or in any way initiate it's use?
