11GR2 ASM ASMCMD
今天在做11GR2 RAC环境中，OCR磁盘被拿走的实验时，在restore ASM磁盘组的原数据时，遇到了下面的奇怪的错误。测试环境是：OS REDHAT 5.6 X86_64OS ：11.2.0.2 （RAC）
1.备份OCR DISKGROUP原数据。
[*]$ asmcmd md_backup /home/grid/ocrbackup -G 'OCR';
[*]Disk group metadata to be backed up: OCR
[*]Current alias directory path: POWER/PARAMETERFILE
[*]Current alias directory path: test
[*]Current alias directory path: test/ASMPARAMETERFILE
[*]Current alias directory path: test/OCRFILE
[*]Current alias directory path: POWER
2.DD掉OCR盘
[*]# dd if=/dev/zero of=/dev/asm-diskb bs=1024M count=1111
[*]dd: writing `/dev/asm-diskb': No space left on device
[*]2+0 records in
[*]1+0 records out
[*]1073741824 bytes (1.1 GB) copied, 23.5048 seconds, 45.7 MB/s
3.关闭CLUSTER与启动CLUSTER到excl
中间一些步骤这里就不发出现了，将会在另一篇中专门讲OCR盘被拿走的处理。
[*]# crsctl stop has -f
[*]# crsctl start crs -excl -nocrs
4.还原OCR DISKGROUP原数据
[*]$ asmcmdmd_restore /home/oracle/ocrbackup--full --silent -G 'OCR'
[*]ASMCMD-09345: could not open intermediate file '/home/oracle/ocrbackup'
[*]Permission denied
[*]#这里报权限不够，文件是由grid这个用户生成的，也是在grid这个用户下面。
[*]#查看一下权限
[*]$ ls -l

[*]#找到google.metalink都没有相关的报错，没有办法了。
[*]#突然想到把它移到到/tmp下面试一下，结果成功了。
[*]$ mv ocrbackup /tmp

[*]$ asmcmd md_restore /tmp/ocrbackup --full --silent -G 'OCR'

这就是这个奇怪的错误。不知道是什么原因。
