rman备份时遇到以下报错:

channel c4 disabled, job failed on it will be run on another channel
RMAN-03009: failure of backup command on c5 channel at 11/18/2020 11:25:08
ORA-19504: failed to create file "/back/orcl/prod_arch1_28vfquok_1_1"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

好的,在aix平台上编辑/etc/filesystems,加入以下

/back:
        dev             = "/dbbak"
        vfs             = nfs
        nodename        = 192.168.1.2
        mount           = true
        options         = rw,bg,hard,retry=1,rsize=32768,wsize=32768,timeo=600,vers=3,proto=tcp,sec=sys
        account         = false
重新mount
