When I execute:
$ mount /dev/sda /mnt/sda -t btrfs -o subvol=/,X-mount.mkdir
it works as expected.
However when I put it into the /etc/fstab like this:
/dev/sda /mnt/sda btrfs subvol=/,X-mount.mkdir,noauto 0 0
and then call the mount, it fails:
$ mount /dev/sda /mnt/sda
mount: /mnt/sda: mount point does not exist.
dmesg(1) may have more information after failed mount system call.
Can anyone please spot what I’m doing wrong ?
I don’t think systemd supports X-mount.mkdir. I believe that may only work with the mount command.
When /dev/sda has the entry you show in fstab, use either mount /dev/sda or mount --target /mnt/sda.
Thank you !
For the fstab entry I’ve presented, both of these ways works for me on F39:
mount /dev/sda
mount --target /mnt/sda
The directory is created as expected, which means that this:
wasn’t problem.
I see, your issue was with the mount command syntax. I thought you wanted that fstab entry to work without manually calling mount.
I didn’t read carefully enough.
