How to get Dolphin/Plasma to use .Trash-1000 directory on zfs dataset

Help

Hello,

Dolphin/Plasma (not sure where the fault lies) does not seem to recognize external mounted zfs volumes as removable media. They don’t appear in the sidebar nor in the trash settings. As such, if I try to move anything to the trash on a zfs volume, it tries to copy it to the trash in my home directory.

I set the zfs mountpoint to /media/myuser/myZFSvolume and created a .Trash-1000 directory (/media/myuser/myZFSvolume/.Trash-1000) with the correct permissions (chmod 700), but still no luck.

For comparison, nautilus recognizes this zfs volume as removable media and properly uses its .Trash-1000.

Can someone explain how to get Dolphin/Plasma to recognize a mountpoint as an external removable volume?

And apologies in advance if I’ve used any terminology here incorrectly.

That’s bugs.

Regarding the trash.

The bug must be somethere or in Kmountpoint:

Can you share the result of command mount

And about dolphin not showing in places panel, this is probably a bug in solid.

Could run solid-hardware6 list command (might be solid-hardware for your distro?).

Then in the output try to identify your partition, it should start with something like: /org/freedesktop/UDisks2/block_devices/

And copy the udi value for it and run
solid-hardware6 details <UDI>

For instance on my local partition, that is:

$ solid-hardware6 details /org/freedesktop/UDisks2/block_devices/nvme0n1p2
udi = '/org/freedesktop/UDisks2/block_devices/nvme0n1p2'
  parent = '/org/freedesktop/UDisks2/drives/SKHynix_HFS002TEJ9X162N_ASCAN41151CA9AG08' (string)
  vendor = '' (string)
  product = 'SKHynix_HFS002TEJ9X162N' (string)
  description = 'Lecteur chiffré de 1,9 Tio' (string)
  icon = 'drive-harddisk' (string)
  Block.major = 259  (0x103)  (int)
  Block.minor = 2  (0x2)  (int)
  Block.device = '/dev/nvme0n1p2' (string)
  StorageAccess.accessible = false (bool)
  StorageAccess.filePath = '' (string)
  StorageAccess.ignored = true (bool)
  StorageAccess.encrypted = true (bool)
  StorageVolume.ignored = false (bool)
  StorageVolume.usage = 'Encrypted'  (0x5)  (enum)
  StorageVolume.fsType = 'crypto_LUKS' (string)
  StorageVolume.label = '' (string)
  StorageVolume.uuid = 'f0eb2a01-98e5-49cb-9fe8-81059d33c155' (string)
  StorageVolume.size = 2047333105664  (0x1dcae900000)  (qulonglong)

udisksctl dump

This should be good to qualify the bug.

I ran into the same issue; zfs volume doesn’t show up in dolphin and deleted files get moved to the root filesystem.

$ mount -l | grep LinuxData
LinuxData on /media/LinuxData type zfs (rw,xattr,noacl,casesensitive)

in solid-hardware only the physical devices and the zfs member partitions show up. nothing related to zfs volumes.
