What's the collocation on that pool set for? If it's collocated by node or by group, you might be seeing each node migrating.

Some background - The archive pool (called ARCHIVEPOOL) has 5 disk volumes, all at 8 GB. Max file size is 5 GB. Migration threshold is 60%. Maxproc is 2. So when we reach 60% or above in the pool, two processes kick off. And we migrate all the way down to 0%. But what I see in the log looks like this: ANR0984I Process 4758 for MIGRATION started in the BACKGROUND at 02:26:20. ANR1000I Migration process 4758 started for storage pool ARCHIVEPOOL automatically, highMig=60, lowMig=0, duration=No. ANR0513I Process 4758 opened output volume 444019L4. ANR1001I Migration process 4758 ended for storage pool ARCHIVEPOOL. ANR0986I Process 4758 for MIGRATION running in the BACKGROUND processed 256 items for a total of 7,094,272 bytes with a completion state of SUCCESS at 02:26:22. ANR0984I Process 4759 for MIGRATION started in the BACKGROUND at 02:26:23. ANR1000I Migration process 4759 started for storage pool ARCHIVEPOOL automatically, highMig=60, lowMig=0, duration=No. ANR0513I Process 4759 opened output volume 444019L4. ANR1001I Migration process 4759 ended for storage pool ARCHIVEPOOL. ANR0986I Process 4759 for MIGRATION running in the BACKGROUND processed 256 items for a total of 8,732,672 bytes with a completion state of SUCCESS at 02:26:25. ANR0984I Process 4760 for MIGRATION started in the BACKGROUND at 02:26:27. ANR1000I Migration process 4760 started for storage pool ARCHIVEPOOL automatically, highMig=60, lowMig=0, duration=No. ANR0513I Process 4760 opened output volume 444019L4. ANR1001I Migration process 4760 ended for storage pool ARCHIVEPOOL. For several hours. For some reason the pool is over 60% full; migration kicks in and 15.7 MB migrates; the migration ends; and the pool is STILL over 60% full. Why?? More importantly, how do I fix this?
