I have recently configured a new lvm through the gui and now it will not boot. How do i fix this?

Hi,

Can you please provide us the syslog.
1. In the screenshot you attached, you can get a shell (by enter your root password)
2. open a `tmux` or `screen` and split it to two shells
3. On the first shell run the `journalctl -f > /tmp/$(hostname)-syslog.log`
4. On the second shell, try to activate the `bigdata` using vgchange like the following command:
Bash:
vgchange -ay bigdata

wait a 30~ seconds and then Ctrl+C on the journalctl and provide us with the log.
