volume reaches to 0% free space or used is paces is 100% ? will volume access be denied

[sam176]

• The reason I am asking that I have some windows Luns in some volumes and those volumes keep using more space maybe because some sort of logs written to the LUN so I keep expanding the size of lun not  knowing or sure exactly what will happen if I just let it fill the whole volume to 100%

If a volume goes full and has a LUN in it, the LUN will go offline to protect data.

There are many tools to help manage this like volume autogrow. That would be good to set up, and if you have OnCommand Unified Manager you can set up alerting and it should give alerts when it gets full so you can catch it sooner.
