NC | NSFS | List Objects with s3 ls of a Bucket Shows an Hidden Directory (Probably not in Normal Flow)

[shirady]

Environment info

• NooBaa Version: 5.19
• Platform: NC

Actual behavior

1. When using the AWS CLI of list objects with s3 ls I could see the hidden internal directory (PRE .noobaa-nsfs_67d7ed5f51c5043305fee625/). Note that the bucket ID is 67e2accc57cf31f3f0d80f31.

Expected behavior

1. When using the AWS CLI of list objects with s3 ls and not see any hidden internal directory.

Steps to reproduce

I'm not sure what exactly I did but I can guess that I reused the same path for creating a bucket with the name bucket-01, and then deleting it (configuration-wise - delete with sudo rm -rf /etc/noobaa.conf.d/) and created the bucket again bucket-01 with noobaa-cli In the same path with the same name I had the previous hidden folder so it shows it as an item.

ls -al /Users/buckets/bucket-01

-rw-rw----@  1 1001         admin   13 Mar 25 21:39 hello_world1.txt

67e2accc57cf31f3f0d80f31 the bucket ID that was created with noobaa-cli in that time,
67d7ed5f51c5043305fee625 probably old bucket ID that was deleted from the config, but it's underlying storage was not deleted.

The outputs of list-objects-v2 and list-objects are as expected (no hidden folder appears):
