版本OEL5.7 86_64+ORA 11GR2+GRID+ASM
我想通过kfed查看某个文件的au分布,比如非元数据265号文件:- sys@GT11G> show parameter spfile;
- NAME TYPE VALUE
- ------------------------------------ ----------- ------------------------------
- spfile string +DATA01/gt11g/spfilegt11g.ora
- +ASM> select name,group_number,file_number from v$asm_alias where lower(name)='spfilegt11g.ora';
- NAME GROUP_NUMBER FILE_NUMBER
- -------------------- ------------ -----------
- spfileGT11G.ora 1 265
- +ASM> select name,group_number from v$asm_diskgroup;
- NAME GROUP_NUMBER
- -------- ------------
- DATA01 1
- FRA 2
- SYSDG 3
- +ASM> select group_kffxp,number_kffxp,pxn_kffxp,xnum_kffxp,disk_kffxp from x$kffxp where group_kffxp=1 and number_kffxp=265;
- GROUP_KFFXP NUMBER_KFFXP PXN_KFFXP XNUM_KFFXP DISK_KFFXP
- ----------- ------------ ---------- ---------- ----------
- 1 265 0 0 1
- +ASM> select group_number,disk_number,path from v$asm_disk where group_number=1 and disk_number=0;
- GROUP_NUMBER DISK_NUMBER PATH

复制代码 通过上述信息,我得到的是:
256文件开始相关的au分布信息是存放在磁盘1的au31位置,但是我通过kfed查看该位置的信息居然不对:- [grid@gtser2 ~]$ kfed read /dev/asm11g-g aun=31 blkn=11 | more

复制代码 如果正确的话,应该这里看到的只是有kffed[0]的数据信息有正确的配置。
