After some more playing around, I realized that I was slightly off in my initial analysis. It's not /etc/fstab that it obtains the /dev/vg/* references from, but lvdisplay:
$ sudo lvdisplay --config 'log{command_names=0}' -c -a WARNING: Device /dev/mapper/sda5_crypt has size of 1950040760 sectors which is smaller than corresponding PV size of 1950302578 sectors. Was device resized? One or more devices used as PVs in VG vg have changed sizes. /dev/vg/root:vg:3:1:-1:1:83886080:10240:-1:0:-1:253:1 /dev/vg/swap:vg:3:1:-1:2:17301504:2112:-1:0:-1:253:2 /dev/vg/home:vg:3:1:-1:1:429916160:52480:-1:0:-1:253:3 /dev/vg/music:vg:3:1:-1:1:205832192:25126:-1:0:-1:253:4 /dev/vg/documents:vg:3:1:-1:1:209715200:25600:-1:0:-1:253:5 /dev/vg/pictures:vg:3:1:-1:1:167772160:20480:-1:0:-1:253:6 /dev/vg/downloads:vg:3:1:-1:1:41943040:5120:-1:0:-1:253:7 /dev/vg/video:vg:3:1:-1:1:209715200:25600:-1:0:-1:253:8 /dev/vg/vm:vg:3:1:-1:1:146800640:17920:-1:0:-1:253:9 /dev/vg/git:vg:3:1:-1:1:41943040:5120:-1:0:-1:253:10 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1816214 Title: Thinks logical volume is not mounted because it's not using /dev/mapper/vg-* path To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-lvm/+bug/1816214/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
