rclone indicates the folder was deleted, but it still exists when listing, or looking directly in the bucket in GCP.

I've tried all the methods I could find to delete one folder, rclone purge, rclone rmdir, rclone rmdirs, rclone delete, or rclone mount as a local disk and doing simple cmd.exe rd on the folder I'm trying to delete. The local cache in rclone mount indicated the "deleted" folder was not found, but if I flush the cache or just re-mount the same bucket, the folder reappears.

It never shows an error with -vv or -log-lever DEBUG, never shows "folder is not empty". The commands DO delete all files in the folder path as expected, but it refuses to delete the empty folders.

I also tried the various --delete-after type commands, --rmdirs, etc. They all indicate that the folder was deleted, no errors, but it doesn't get deleted.

Is there another --command to make it work?

Side note, I'm switching to rclone from old CloudBerry Drive (no longer supported, latest .net patches broke core functionality, etc). rclone does everything I need it to and performs way better/faster, the only thing I'm stuck on it getting a folder to actually delete. The same simple cmd.exe rd commands worked fine since ~2015 with CloudBerry in AWS and in GCP, not sure what I'm missing.

welcome to the forum,

as per rclone docs,
"Empty folders are unsupported for bucket based remotes"

i know with AWS S3 and clones, when using their website, a marker is created.
also, most other third-party S3 tools also create that marker.

in the past and still by default, rclone does not create markers.
over the years, this has been much discussed/debated in the forum.

so might just manually delete them and going forward use --gcs-directory-markers

i can tell you from experience, the mount really does not like empty folders.

fwiw, i dumped cloudberry for veeam, over five years ago.
veeam community editions are free and much more powerful than rclone.

Ok, --gcs-directory-markers might be what I need, I'll test next week. It won't help with my existing bucket (PB/billions of files). I've used veeam a while ago, didn't much care for it. I wrote my own solution for what I need, works fine for my role.

I'll reply if --gcs-directory-markers works going forward next week. Thank you!

well, at least we agree about cloudberry ;wink

perhaps use rclone to do a server-side move to a new bucket.
tho really, it is a server-side copy then delete.

and did you see
https://rclone.org/overview/#optional-features

rclone backend features remote:
should show
"CanHaveEmptyDirectories": false"

Yes confirmed, no empty dirs. Not sure how CloudBerry did it, I don't see any hidden files or obvious weirdness.

I might be able to do a hybrid using old CloudBerry just for purges for 6 months to cover the old ones pre --gcs-directory-markers, should be good enough for short term.

Yeah just to confirm, I was able to reinstall CloudBerry just for the old folder purge part, that will be good enough short term. The latest .NET patches broke uploads in CloudBerry (broke the headers sent to GCP). I'll test the new folders from rclone after the weekend (nothing new to create till the next day). Thanks again for the help!

I got new folders created over the weekend with new uploads using rclone and --gcs-directory-markers, unfortunately I don't see any change in the folders or files, and a cascade delete of a folder only deletes the files in the subfolders, it still refuses to purge the empty folders.

Any other ideas?

In the meantime I am able to use old CloudBerry to do the purges of older files and folders without any issues. But who knows how long before that breaks.

I noticed that --gcs-directory-markers defaults to false, so I'm hoping just adding literally " --gcs-directory-markers" to the command is still defaulting to false. I added --gcs-directory-markers=true and will see what happens with new folders overnight.

No change, and new folders still refuse to be actually deleted from rclone.

--gcs-directory-markers=true doesn't seem to change anything from what I can tell.

Anyone else know what I might be missing here? I wouldn't think deleting one empty folder would be this difficult. :slight_smile:

edit: here comes @ncw to the rescue!

Do an rclone rmdir on a single empty folder with --gcs-directory-markers=true -vv --dump bodies --retries 1 and post the output. That should show us what the command is doing.

Semi-redacted for private bits, looks like it's getting a 404 not found?

Hmm, I think removing a directory marker if it is specified in the root is broken :frowning:

I tried removing the directory by mounting the parent and issuing an rmdir and that did work!

How have you been trying to delete the directory?

I've tried all the methods using rclone by itself, and with mounting the bucket as a local disk and using simple rd [path] /s /q or using old fashioned filesystemobject folder.delete. It shows deleted in local cache, but the folders persist no matter how I try to delete.

I can still use the mounted volume for discovery and kick off individual rclone direct deletes if that works. But this is a LOT of deletes every day (old backup folders going back 6 months), like a rolling window of deletes kind of thing. Not sure if you had success mounting as a local disk and deleting? (this would be difficult to scale I suspect on my side doing one by one mount/delete/unmount).

Also in my bucket, the folder structure looks like this:

bucket -> server -> date -> type -> folder (and multiple files under this last folder)

There's multiple server, multiple date, multiple type. I'm mapping and using the bucket root for sure.
