Are you running the CRR server? I seem to remember that, even though you do not need it for its stated purpose, it is needed for performance reasons.
Another p[possibility is that the log m-disks might be filling up. The control data backup is initiated at 80% full, a non-configurable but arbitrary size. If, while that backup is running, it reaches 95%, all activity is suspended until it is below a given percentage.

You can run a FILEPOOL REORG, that will only reorganise storage pool 1, that is, the SFS DB2-like catalog. There is no tool to reorganise the other storage groups (apart from a backup & restore). 2011/3/31 Tony Thigpen <t...@vse2pdf.com<mailto:t...@vse2pdf.com>> It's been a long time since I managed a production SFS system so I need a little refresher. On our development system, I ran out of space on my SFS pool, but was able to reduce the usage down to just 45% by deleting a bunch of stuff we no longer needed. Now the SFS seems 'slow'. Do I need to run a job to 'compress' the SFS or re-org the directory? -- Tony Thigpen -- Kris Buelens, IBM Belgium, VM customer support
