ASM kfed repair到底干点啥？

官方对于kfed repair命令的描述比较简单:Recover the disk header from the redundant copy of it maintained on an unused portion of the disk. 其主要用来disk header的头4096 bytes的KFBTYP_DISKHEAD结构，这个恢复是基于10.2.0.5以后的Disk Header自动备份机制的。其在PST即AU=1的最后第二个数据块中(Read from PST(AU 1)’s penultimate Block)自动备份了KFBTYP_DISKHEAD。

 

如:

由于ASM 有这个备份，所以kfed repair可以自动修复ASM disk header的最开始的4096 bytes，但又由于这个备份只备份4096字节的metadata，所以它不能应对整体metadata(除掉KFBTYP_DISKHEAD外）还有大量的其他必须的metadata元数据。

之前在用户现场发现kfed repair也能修复PST KFBTYP_PST_META中的部分逻辑讹误/损坏，但一直无法在自己的环境中重现。

在以上场景中未重现KFED 修复KFBTYP_PST_META的元数据，其仅仅读取了偏移量为2088960的（2088960/4096=510=255+255 即AUN=1的最后第二个块）的4096字节，并写入到OFFSET=0的地方。

 

 

具体查看了以下KFED的源代码 ， 也并未发现其会修复其他地方metadata的线索：

 

#define KFEDOP_REPAIR ((kfedop)13)      /* Repair ASM disk header            */
www.askmac.cn

  case KFEDOP_REPAIR:
    /* Read from PST(AU 1)'s penultimate Block */
    cx->aunum_kfedcx  = (ub4)1;
    cx->blknum_kfedcx = (ub4)(bfact - 2);

    if (!kfedReadBlk(cx))
      goto done;

    /* Validate the Disk Header block read from PST */
    if(!kfedValidateBlk(cx, KFBTYP_DISKHEAD))
      goto done;

    /* Fix the block number and checksum in the buffer */
    if (!kfedFixBackupHeader(cx)) www.askmac.cn
      goto done;

    /* Write to Disk Header(AU 0 and Block 0) */
    cx->aunum_kfedcx  = (ub4)0;
    cx->blknum_kfedcx = (ub4)0;

    if (!kfedWriteBlk(cx))
      goto done;

    break;

以上代码可以理解为，KFEDOP_REPAIR操作读取PST(AU 1)’s penultimate Block即AUN=1的最后第二个块，若无法读取则直接报错，若可以读取则验证从PST中读取的DISK header的block,并FIX其中的block number以及checksum值，之后写出到disk header即AUN=0 BLKN=0的地方。

 

总之，如果确实遇到了此类ASM的问题，那么在充分备份DISK HEADER后（备份前200MB是必要的），在有DISK HEADER自动备份的情况下，尝试KFED REPAIR一下吧，如果不能成功那么后续会有一堆的诊断metadata和手动修复工作等着我们呢。
