Informix Error -21532: Defragment: The partition is in the wrong state or an incompatible type

Reasons / Common Causes

-21532 fires when the target partition is in a state or of a type that defragmentation doesn't support — per the official guidance.

1. A conflicting action currently occurring on the partition, per the official guidance — the first named case.
2. A partition type that can't be defragmented, per the official guidance — the second named case; see the IBM Informix Data Server Administrator's Reference for defragmentation restrictions.

Solutions / Resolution

1. If a conflicting action is occurring, run defragmentation again later, per the official guidance.
2. If the partition's type doesn't support defragmentation, don't defragment it — check the Administrator's Reference for the type restrictions, per the official guidance.

Examples

N/A

No specific triggering statement is documented beyond a state/type-incompatible partition.

Diagnostic Checks

1. Check for a conflicting operation on the partition, and check its type against the documented defragmentation restrictions.

• -21531 — "Defragment: A partition that contains a partition header page table cannot be defragmented." A specific case of this restriction, for partition header page tables.
• -21533 — "Defragment: A defragmentation task is already in progress on this dbspace." A related restriction, on a concurrent defragment task rather than partition state/type.

The partition's state or type doesn't support defragmentation — retry later if a conflicting action is running, or check type restrictions.
