3par-FC Raw Space usage

[gykim]

There is a problem with the 3par 10400. There is a warning that raw space usage exceeds 95%.

On the customer side, data has not been inserted into the data volume since a year and a half ago, usage has remained 85% in 2021 and usage has increased since 2022, and the most suspected reason for the increase is the file growth in the snapshot volume. I wonder why the files on the snapshot volume can suddenly increase and if the files on the snapshot volume are erased, it will affect the backup.

It also confuses the raw allocation space with the raw usage space.

What corrective actions should be taken in the future?
