How to safely remove swap partition in Red Hat Enterprise Linux?
Issue
-
Is there a way to stop active swap disks, so that they can move their load to other swap disks?
-
Server being migrated from old SAN arrays to a new array. Secondary swap is currently in use as swap disks on the old array and the new array.
-
From below list, I want to stop sda2 and sda3, but they have a multi-threaded load with primary swap. I'm assuming that only a reboot will let me drop them (already commented out in fstab).
# swapon -s
