Hi,
I'm trying to export gluster-volume by nfs-ganesha.
After create --> Some I/O --> delete file from nfs mount point.
The file has been moved to ./glusterfs/unlinkls.
There was an fd leak when a file is created using gfapi handleops (which
NFS-Ganesha uses) and FWIU, if there is an open fd, glusterfs-server
moves the file being removed to ".glusterfs/unlink" folder unless its
inode entry gets purged when the inode table which it maintains gets
full or the brick process is restarted.
The fix for "glfd" leak is already merged in master -
"http://review.gluster.org/#/c/14532/";
Will backport this patch to 3.7 branch. If 3.7.13 merge window gets
closed, the fix shall be available in 3.7.14. Till then to get past this
issue, request to restart brick process.
Thanks,
Soumya
