db2在线备份异机恢复问题

命令和问题如下：

$ db2 restore database sample from /db2Bak taken at 20161017234522   

DB20000I  The RESTORE DATABASE command completed successfully.

$ db2 connect to sample

SQL1117N  A connection to or activation of database \"SAMPLE\" cannot be made

because of ROLL-FORWARD PENDING.  SQLSTATE=57019

$ db2 rollforward db sample to end of logs

SQL1268N  Roll-forward recovery stopped due to error \"24\" while retrieving log

file \"S0000578.LOG\" for database \"SAMPLE\" on node \"0\".

然后把S0000578.LOG从备份的机器上复制到恢复的机器上的***/NODE0000/SQL00001/SQLOGDIR/目录下继续执行db2 rollforward db sample to end of logs这个命令就卡在这不动了，请问该怎么解决
