I have a btrfs partition with several subvolumes, one of which is /. I have another subvolume with some other stuff that I also want to mount, but trying to mount it with udisksctl:udisksctl mount -b /dev/mapper/container -o subvol=othergives me this error:Error mounting /dev/dm-0: GDBus.Error:org.freedesktop.UDisks2.Error.AlreadyMounted: Device /dev/dm-0 is already mounted at `/'.It mounts fine with mount /dev/mapper/container -o subvol=other /mnt. Is there anything I can do to get this to work with udisksctl?
udisksctl mount a different subvolume of an already mounted btrfs partition
mount;btrfs;udisks
First read the man page (man udisksctl)! It says you should use --options.If this is not working, then subvol is considered an unsafe option (IMHO, it should). If so, you can use the mount command or you can set the options directly in /etc/fstab for a given mount point.
