LS520 showing as 100% full
« on: January 31, 2019, 03:49:49 am »
I have a LS520 with 2 x 4TB drives in Raid 0 configuration.  I have been backing up 4 x PC's to this drive for a few weeks.  Now the NAS is showing 100% full and the backups are failing.
I have tried deleting some backups and emptied the trash folder but drive still shows 100% storage used.

Surely the backup software should delete old backups after x days when writing on new backups?  I need this fixed ASAP as I now have no backups running for any of my PC's

Hi, I am having the same problem with a TeraStation HD-HTGL/R5 I purchased another NAS and moved several hundred gigs of data as the drive (raid 5) was showing signs of becoming full but despite this the TeraStation is now 100% full, all the trash boxes have been cleared just to be sure, did you ever get a resolution to your problem? from what I have read this seems to be a recurring issue with some of the Buffalo drives
