In my limited knowledge of the original reasons for 1GB hardcode, either removing the limit altogether, or an additional “override" option parameter would be preferable in my humble opinion.

Hi all,
gluster volume
set <VOLNAME> features.trash-max-filesize
<size>
This command
can be used to filter files entering trash directory based
on their size. Files above trash_max_filesize are
deleted/truncated directly.Value for size may be followed by
multiplicative suffixes as KB(=1024 bytes), MB(=1024*1024
bytes) and GB(=1024*1024*1024 bytes). Default size is set to
5MB. Considering the fact that trash directory is consuming
the glusterfs volume space, trash feature is implemented to
function in such a way that it directly deletes/truncates
files with size > 1GB even if this option is set to
some value greater than 1GB.
Is there any
workaround (short of changing source code and rebuilding) that
can allow me to override this 1GB hard limit? We store a lot
of large files, and having a limit of 1GB greatly reduces the
value of this trashcan feature for us.
I don't remember exactly reason behind having a hard coded value for
upper boundary, one reason may be to limit space used
by trash directory and for truncate operation it result in
performance hit. The hard coded value can be found at
xlators/features/trash/src/trash.h:32 (GF_ALLOWED_MAX_FILE_SIZE) .
If you are interested , then change value(according to
your preference) in the code and send out a patch to http://review.gluster.org/
as well.
As first step please file a bug https://bugzilla.redhat.com/
under community->glusterfs->trash xlator.

Many thanks,
