    Unanswered: db2ckbkp shows errors in backup file

    I ran db2ckbkp on some of our backup files and got errors:

    However I restored some databases with no problems and others had to do restore redirect. Does anyone know what those errors above are? Backup was done on v8.2 and restore on v9.5.1. Thanks

    Was db2ckbkp done on v8.2 or v9.5? I'd suggest to do it on the same level where the image was created. Don't worry about the errors if you can restore the image.

    I did db2ckbkps on v9.5.1 once started having problems with simple restore.

    I worry because we had problems with pagesize of tablespaces in some of those DBs before. So I created bufferpools and tablespaces with 16K pagesize to fix the problem and now I am thinking if I did it right
