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.

Many thanks,
