Hello,   No it won't at all.  The only time a volume will go offline, if it's thin provisioned and you have over provisioned that pool.    Since the volume it thick provisioned you have pre-allocated the space you can't run out.   The OS / filesystem knows what blocks are available for re-use.  So even when the EQL GUI shows 100% full, that just means that all the pages for that volume have been written to.  When the OS deletes a file, by default it doesn't tell the storage that block is now free.  There is a new SCSI feature called "UNMAP" aka "Space reclaim" that does tell the storage to release unused blocks.  Not every OS or filesystem supports that feature.   However, in your case since you are not using thin provisioning there's no benefit to freeing up space, since all that will happen is that in-use bar will more closely match what the OS says.   But you always need to go by what the OS says vs. storage.   Regards,  Don   
Hello, I have one standard 70G volume (not Thin Provisioning) with only has 300MB free space left. Will it impact the performance with this little free space left or cause volume offline if volume grows? Thanks, JY
