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,
