Status: Closed |
INSUFFICIENT SYNCHRONIZATION OF (MIRROR CHUNK) RESERVED PAGES EXTENSIONS AMONG CLUSTER NODES
|
| product: |
INFORMIX SERVER / 5725A3900 / E10 - |
| Problem description: |
Primary server and secondaries can disagree on existence (or
location) of mirror chunk extended reserved pages, also leading
to extent overlaps in rootdbs and potentially worse
consequences. This can occur when MIRROR onconfig parameter
gets modified, from 1 to 0, on primary and, while the actual
corruption occurs on the secondaries, it would only lead to real
trouble once such secondary assumes primary (or standard) role,
even if only temporarily.
An indication for this problem is 'oncheck -ce|-pe rootdbs'
reporting extent overlap between reserved pages and other
extents, on a secondary server or one that once was a secondary
server. |
