It could be a couple of things, either something changed at the host file system layer, or possibly free space in the DDS being slow to reclaim due to the firmware level and older hardware. These appear to the be the offending volumes and are all dedupe volumes: Vol1_PRD_BDKC1 dboracle1 dboracle2 Vol1_PRD_BDIC1 However since both reserved and used space are pretty close it could be that some large changes have occurred at the file layer and the array hasn't been made aware of these. First thing I'd try would be to run an unmap to signal the reserved space can be reclaimed. Have a look at this WP appendix A for reclaim techniques : https://h20195.www2.hpe.com/V2/Getdocument.aspx?docname=a00006358enw |

And what about reducing the sparing volumes ? |

Maybe you could benefit of an Inform OS update to jump to 3.3.1 : some major issues with TDVV v2 are fixed, relating to space reclaim... |

Yes you could reduce the sparing level but it would potentially reduce availability and wouldn't really solve the problem at hand, only mask it temporarily. Try the unmap initially and make sure you're on a current firmware release. |
