Set timestamps with another user not allowed

[cberni]

What is the problem you are having with rclone?

RCLONE_UID=557 ('pacs' user)
RCLONE_GID=557 ('pacs' user)

sudo -u pacs touch -d "2020-01-01 00:00:00" /union/pacs-user.txt
(runs ok)

sudo -u tomcat touch -d "2020-01-01 00:00:00" /union/tomcat-user.txt
touch: setting times of '/union/tomcat-user.txt': Operation not permitted

We're encountering some issues when another user tries to set file timestamps.

In this case, the filesystem is mounted as 'pacs', and the issue occurs when attempting to create a file as the 'tomcat' user.

Run the command 'rclone version' and share the full output of the command.

rclone v1.69.1
- os/version: ubuntu 24.04 (64 bit)
- os/kernel: 6.8.0-1023-oracle (x86_64)
- os/type: linux
- os/arch: amd64
- go/version: go1.24.0
- go/linking: static
- go/tags: none

Which cloud storage system are you using? (eg Google Drive)

google cloud storage

The command you were trying to run (eg rclone copy /tmp remote:tmp)

/usr/bin/rclone mount union: /union --union-upstreams /local:writeback remote:bucket --log-file=/var/log/animati/union/mount-rclone.log -vvv --allow-other --default-permissions --use-mmap --disable-http2 --rc

The rclone config contents with secrets removed.

[union]
type = union
action_policy = all
create_policy = all
search_policy = ff

[remote]
type = google cloud storage
service_account_file = bucket.json
no_check_bucket = true
