Eric,
Thanks for the reply. This is not on a lun, it is an NFS volume and there are no snapshots. The sys log shows no errors. You can actually see what happens buy.
Setup a volume and publish via nfs.
from the host (I used a unix host) mount the volume.
I then created a 10 GB file on the volume (mkfile 10Gb test)
I then do DF -h and look at the space usage on the volume.
I then delete (using rm) the 10 GB file
when you run the rm command you get your prompt back and can do other things
However, I then run DF -h (over and over again) and you can see the space freeing up on the volume as that file is deleted in the background. It takes about 40 seconds to delete the 10 Gb file.
so if you have a 500 GB you are deleting it can take around 33 minutes to delete 500 GB.
I also talked to NetApp and they say there is no ay to adjust this, I have asked them if flexscale priority would make any difference.
