I found an error in the line above that in fstab, # it out. Using htop as a swap monitor I can make the swap come and go. Heres the fstab now: proc /proc proc defaults 0 0 PARTUUID=4fb6ef8f-01 /boot vfat defaults 0 2 PARTUUID=4fb6ef8f-02 / ext4 defaults,noatime 0 1 # but lets see if a swap can be made to work PARTUUID="000ba889-02" none swap defaults,nofail 0 0 #/dev/sda2 none swap sw,nofail # a swapfile is not a swap partition, no line here # use dphys-swapfile swap[on|off] for that LABEL=bootpi /media/boot vfat defaults 0 2 LABEL=workpi1 /media/slash ext4 defaults,noatime 0 1 LABEL=backuppi /media/backupsd ext4 defaults,noatime 0 1 LABEL=workpi120 /media/work ext4 defaults,noatime 0 1 But it doesn't show in a mount, nor does it show in a cat /etc/mtab: /dev/root / ext4 rw,noatime,data=ordered 0 0 devtmpfs /dev devtmpfs rw,relatime,size=468264k,nr_inodes=117066,mode=755 0 0 sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 proc /proc proc rw,relatime 0 0 tmpfs /dev/shm tmpfs rw,nosuid,nodev 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 tmpfs /run tmpfs rw,nosuid,nodev,mode=755 0 0 tmpfs /run/lock tmpfs rw,nosuid,nodev,noexec,relatime,size=5120k 0 0 tmpfs /sys/fs/cgroup tmpfs ro,nosuid,nodev,noexec,mode=755 0 0 cgroup /sys/fs/cgroup/systemd cgroup rw,nosuid,nodev,noexec,relatime,xattr,release_agent=/lib/systemd/systemd-cgroups-agent,name=systemd 0 0 cgroup /sys/fs/cgroup/cpu,cpuacct cgroup rw,nosuid,nodev,noexec,relatime,cpu,cpuacct 0 0 cgroup /sys/fs/cgroup/blkio cgroup rw,nosuid,nodev,noexec,relatime,blkio 0 0 cgroup /sys/fs/cgroup/memory cgroup rw,nosuid,nodev,noexec,relatime,memory 0 0 cgroup /sys/fs/cgroup/devices cgroup rw,nosuid,nodev,noexec,relatime,devices 0 0 cgroup /sys/fs/cgroup/freezer cgroup rw,nosuid,nodev,noexec,relatime,freezer 0 0 cgroup /sys/fs/cgroup/net_cls cgroup rw,nosuid,nodev,noexec,relatime,net_cls 0 0 tmpfs /etc/machine-id tmpfs ro,mode=755 0 0 systemd-1 /proc/sys/fs/binfmt_misc autofs rw,relatime,fd=22,pgrp=1,timeout=300,minproto=5,maxproto=5,direct 0 0 debugfs /sys/kernel/debug debugfs rw,relatime 0 0 mqueue /dev/mqueue mqueue rw,relatime 0 0 configfs /sys/kernel/config configfs rw,relatime 0 0 fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0 /dev/mmcblk0p1 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro 0 0 /dev/sda1 /media/boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro 0 0 /dev/sdb1 /media/backupsd ext4 rw,noatime,data=ordered 0 0 /dev/sda3 /media/slash ext4 rw,noatime,stripe=8191,data=ordered 0 0 /dev/sdb2 /media/work ext4 rw,noatime,data=ordered 0 0 tmpfs /run/user/1000 tmpfs rw,nosuid,nodev,relatime,size=94520k,mode=700,uid=1000,gid=1000 0 0 gvfsd-fuse /run/user/1000/gvfs fuse.gvfsd-fuse rw,nosuid,nodev,relatime,user_id=1000,group_id=1000 0 0 Which seems to be way too complex, but htop says its there. But I did a swapoff -a then a sudo mkswap .dev/sda2 which reported: pi@picnc:~ $ sudo mkswap /dev/sda2 mkswap: /dev/sda2: warning: wiping old swap signature. Setting up swapspace version 1, size = 10239996 KiB no label, UUID=7b06d9bc-18f2-4c25-957d-f426141664b3 So I copied that UUID into /etc/fstab, making this line: UUID=7b06d9bc-18f2-4c25-957d-f426141664b3 swap defaults,nofail 0 0 But now its not working at all. What did I screw up? I rebooted, and its found a 99meg swapfile, probably on the 32GB u-sd, but not /dev/sda2 ??? Call me puzzled.
