Volume shows full, but Pct Util is less than 100%.

[CDixon13550]

Hello all, I have an issue where just about all of our 2 tier backup volumes show they are full, but the percentage used is less than 100%. We had some backups fail last night due to being out of space. I have tried to run reclamation, but it failed due to insufficient space errors. Several of the volumes showed reclaimable space above 20-30%, a few are higher than that. I have included some output below from the q vol cmd and q stg. These are all spinning disks, no tape. Can someone help point me in the direction to possibly fix the issue?

Thanks

Chris

Is there a way to get around this so I will have space for backups to run?

Add space is the only way or off load (migrate) to physical tape (online primary tape pool) or another storage pool.

You can reclaim some space with reclamation by using a lower threshold.
