Thanks Jiffin, filed https://bugzilla.redhat.com/show_bug.cgi?id=1386766
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.
Thanks for filing the bug, patch posted for addressing this issue

Hi all,
Documentation says:
https://gluster.readthedocs.io/en/latest/Administrator%20Guide/Trash/
*/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.
Regards,
Jiffin
Many thanks,
Jackie
