Summary0000437: when storing on multiple volumes via File backend, a data block of 64k gets lost
DescriptionWhen backup jobs on File backend uses multiple volumes, data (64k block) gets lost.

This is recognized on restore:

12-Mar 18:47 sdtest-fd JobId 32: Error: attribs.c:419 File size of restored file /tmp/bareos-restores/tmp/test/test1500 not correct. Original 1536000, restored 1470464.

This does only happen with File backend. With the Tape (Autochanger) backend (mhvtl), this problem did not occur.
Steps To ReproduceDo a normal Bareos package based installation (I've used SLES11, but the problem have been initially reported on Debian 7).

In the Full Pool set

Maximum Volume Bytes = 1M

set the FileSet to a directory

/tmp/test/

and create a file of the size 1,5M in it.

Run full backup of the file (which will use two volumes) and run a restore job.

The restored file is 65536 Bytes (64kb) smaller than the original one.
Additional InformationThe file size of the volumes is smaller than the file it contains.
Therefore the problem already happens when writing to the volumes.

bextract also reports the error.

Originally, this have been discussed on

To be tested on 13.2 and 14.2 (I've done several time restore without seeing this specific issue)

It seems, the problem has been introduced by

commit f964f4cb223cde3ffd57fe902bf2b1a77bfef00f

Implement auto inflation/deflation in the storage daemon.

At least, my automatic test (using git bisect) tells me this.

Ok thanks for that. I have a hunch what goes wrong. Seems to align with
the fact it only happens with auto labeling.

yes, I was only able to reproduce it when new auto labeled volume files were created. Recycled volume files work fine, no restore issue then, but this may only apply for recycled volume files that have been created and auto labeled before upgrade to 14.2

Sorry for the noise.
