I have a DXi-v1000 with 2Tb of space and have run out of space on it.
The decision was made to clean all the data out and start again as it's used for virtual tapes for backups and we have actual tapes of the backups.
I've removed the files, folders and shares held on the device and run the Space reclimation utility which after two days gave me back most of my space.
The system Metadata still uses 340Gb of disk space and I've no idea how to clean it out.
Can anyone point me in the right direction please.
The best and fastest solution for You will be fresh install.
