一:问题描述

备份下归档日志时报错:

RMAN> backup archivelog all format '/home/oracle/backup/rman_bak/';




Starting backup at 06-NOV-14


using channel ORA_DISK_1


RMAN-00571: ===========================================================


RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============


RMAN-00571: ===========================================================


RMAN-03002: failure of backup command at 11/06/2014 08:46:02


RMAN-06059: expected archived log not found, lost of archived log compromises recoverability

ORA-27054: NFS file system where the file is created or resides is not mounted with correct options


Additional information: 3


二:出错原因

mount没挂载对

三:解决办法

解决办法:重新挂载

1:先umount


[root@rac2 ~]# umount /home/oracle/arch


假如,报这个错误:umount: /home/oracle/arch: device is busy


用fuser -k 你的挂载点后,就可以umount掉了。


如:


[root@rac2 ~]# fuser -k /home/oracle/arch


/home/oracle/arch: 29915c 31456c 31457c


[root@rac2 ~]# umount /home/oracle/arch


2:以正确的方式重新挂载:


mount -t nfs -o rw,bg,hard,nointr,rsize=32768,wsize=32768,timeo=600,actimeo=0 rac1:/home/oracle/arch /home/oracle/arch
