[Bug]: Bad Switch

[jurjevic]

Describe the Bug

I followed the instruction and also did chown -R 1000:1000on my tm directory. In the directory, there was alread a sparsebundle backup, which I would like to reuse.

When starting backup, the docker log gets poluted with hundres of error "Bad Switch"

parse_dos_attribute_blob: bad ndr decode from EA on file XXXXX.sparsebundle/mapped: Error = Bad Switch ndr_pull_xattr_DosInfo: ndr_pull_error(Bad Switch): Bad switch value 5 at librpc/gen_ndr/ndr_xattr.c:390 at librpc/gen_ndr/ndr_xattr.c:390

Expected Behavior

No errors in log file

Steps to Reproduce

1. Start container
2. Start backup

Additional Context

No response

[mbentley]

What is the filesystem type where /mnt/user/timecapsule is mounted?

I'm assuming that xxx.sparsebundle/bands/532 is from your pre-existing sparse bundle? I honestly have no idea if you can take a sparsebundle from a previous backup and use it. I'm guessing that's where the error is coming from though, it seems to be complaining specifically about data in the sparsebundle.

[jurjevic]

The filesystem is XFS.

Thats possible thats is comes from the previous sparsebundle. I just don't want to lose all the data. What is the meaning of the error?

[mbentley]

I don't know what the error means. Google doesn't return much and I can't tell from the source code right offhand what exactly it's doing.

[jurjevic]

Okay. Thank you anyway. At least I can confirm, that clean backup doesn't produce this error.

Maybe you could put it into the README as a known issue.

[jurjevic]

Removed old backup and started from clean setup.
