[Request] How do I mount multiple partitions in external disk #1301

Open clustor opened 1 month ago

clustor commented 1 month ago

When I insert a USB drive that has VFAT and EXT4 partitions in Ubuntu, I always see only the first partition mounted. I added a 'udev' rule to mount second partition with SUBSYSTEM=="block" ACTION=="add", KERNEL=="sda5", ENV{ID_FS_LABEL}=="Backup-Linux", RUN+="/usr/bin/udisksctl mount -b /dev/%k" but it fails with exit code 1.

I would like to mount both VFAT and EXT4 partitions. It's not clear to me how selects that first partition be mounted. Any help will be appreciated?

udisks itself doesn't automount devices, it just tells your DE there is a new devices detected and it then tells udisks to mount them so whether a device will be mounted depends on your DE configuration (for example in KDE this is configurable in Disks & Cameras → Device Auto-Mount).

It is possible that we don't correctly inform about all devices, check udisksctl info -b /dev/sda5, especially whether HintSystem and HintIgnore are set to false.

I added a 'udev' rule to mount second partition

udev runs in a separate namespace and manually running mount (or udisksctl) doesn't work from udev rules.

The correct way is to set udev attributes UDISKS_AUTO, UDISKS_IGNORE and UDISKS_SYSTEM (depending on what you're trying to achieve) - see man udisks(8).
