Priority:-2 extents:1 across:2048276k Thank you so much. It seems like, after installing some other distros, swap space labels are being erased. I tried to isolate this problem by making separate swap space for each distro and commenting out any reference to each others partitions. I will remove the '#'. and condense swap to one partition on each disk. Thread start: https://www.redhat.com/archives/fedora-list/2007-June/msg05752.html -- macroron
