The "0 0" fields are defunct and have no meaning anymore... even when they did, they defaulted to 0 if omitted. The /dev/mapper stuff is because I use LVM ( which was handy when I wanted to temporarily create a second swap partition to test this ) and shouldn't matter. This also shouldn't matter, but the other difference I notice is that you are using UUIDs. Maybe you could try changing it to the device path?
Another thing that might be worth checking is manually activating the swap with the swapon command and see if it respects the priority argument. -- 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
