After startup Baloo shows double results of tagged items that are on an external disk on /media/home/blabla. After a 'balooctl purge' everything is okay. Nothing else helps. It's an annoyance, not a major problem, but still: how can I make this annoyance go away?

Turns out that this doubling of Baloo-results only happens when the two external HDD's are directly connected to the two USB 2.0 ports of my laptop. When connected to an USB-hub on the USB-3.0 port the problem is gone. I don't understand why. Ah well, perhaps some timing problem.

Hi!
It also seems to depend on the filesystem and how the device is mounted. baloo is indexing my external storages on my homeserver (nfs and/or sshfs in different folders). Mounting as nfs seems to not trigger a double indexing, using sshfs does. This could be triggered by different user mappings, I don't know. An external ext4-storage works as expected (not automounted).
As this multiple indexing does not occure reproducable, I just purge the index from time to time as you do.

Which filesystem(s) do you use?

I use ext4 on all disks and automatic mounting of the external HDD's.

You could try to use manual mounting via fstab (with `user`-option) or create a corresponding mount-unit for systemd to always mount to the same folder and with the same settings, but I don't know if it helps.
