APAR status
Closed as program error.
Error description
Home returns incorrect sparse information when diskaddrs changes are not yet reflected in the indirect block (addrDirty is true) because flush flag is not acquired to synchronize with steal or sync. This causes cache to read file from home as sparse file.
Local fix
see level2
Problem summary
Home returns incorrect sparse information when diskaddrs changes are not yet reflected in the indirect block (addrDirty is true) because flush flag is not acquired to synchronize with steal or sync. This causes cache to read file from home as sparse file.
Problem conclusion
Fixed the code by acquiring the flushFlag to prevent sync or steal from flushing a buffer, updating an indirect block (commitAssigned) and removing the buffer from the list in between the call to nextDataBlock and iterating over buffer descriptors for checking dirty buffers.
Temporary fix
