  Customer created the
  filesystem with extra small indirect block size (4K).
  This help trigger a problem with how we handle increase
  in indirection level for low level system files.
  

Local fix

• na
  

Problem summary

• GPFS daemon assert: logAssertFailed indBlkIndex * replicas
   * daSize < bufferP->getDataLen() in metadata.C.
  This can happen when increasing number of inodes cause
  indirection level of inode0 file to increase.   Creating
  a new independent fileset is the most likely trigger.
  

Problem conclusion

• Update code to correctly handle insertion of all DA when
  increasing the indirection level of low level system
  file.
  

Temporary fix
