You are very quick to dismiss issues: following your comment, I changed /etc/fstab swap priorities:
# swap was on /dev/sda6 during installation UUID=4870beef-bb2c-40c1-91da-f1444f90c51b none swap sw,nofail,pri=2 0 0 # swap on SSD Samsung UUID=fa2b8ce4-6ce7-4fb2-ac12-475264bed20f none swap sw,nofail,pri=1 0 0 However, the swap order is still incorrect: swapon --summary Filename Type Size Used Priority /dev/sdc2 partition 50331644 0 1 /dev/sda6 partition 50331644 0 -1 To make sure that the right UUIDs are declared: sudo blkid /dev/sda6: LABEL="MSI-GE60-Swap" UUID="4870beef-bb2c-40c1-91da-f1444f90c51b" TYPE="swap" PARTLABEL="Slow-Ubuntu-Swap" PARTUUID="a40b2587-deac-411f-8eee-6da7af30da2a" /dev/sdc2: LABEL="SAMSUNG-Swap" UUID="fa2b8ce4-6ce7-4fb2-ac12-475264bed20f" TYPE="swap" PARTLABEL="Fast-Ubuntu-Swap" PARTUUID="1e289f8b-2281-4ec9-bd01-1b66fc79b359" The issue is still there. ** Summary changed: - Swapon does not respect fstab negative priorities order + Swapon does not respect fstab priorities order -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1516225 Title: Swapon does not respect fstab priorities order Status in util-linux package in Ubuntu: Invalid Bug description: uname -a Linux msi-ge60-ubuntu 4.2.0-18-generic #22-Ubuntu SMP Fri Nov 6 18:25:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux sudo swapon --summary Filename Type Size Used Priority /dev/sdc2 partition 50331644 0 -1 /dev/sda6 partition 50331644 0 -2 However, in /etc/fstab: # swap was on /dev/sda6 during installation UUID=4870beef-bb2c-40c1-91da-f1444f90c51b none swap sw,nofail,pri=-1 0 0 # swap on SSD Samsung /dev/sdc2 UUID=fa2b8ce4-6ce7-4fb2-ac12-475264bed20f none swap sw,nofail,pri=-2 0 0 Does the fact that sdc2 is a SSD makes swapon override the fstab priorities? It is suspicious that swapon prints sdc2 first in the summary. despite the following facts: - sdc2 priority is -2 in fstab - sdc2 is declared after sda2 in fstab - sdc2 is after sda2 in alphabetical order To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1516225/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
