有客户通过sftp误删除oracle数据文件,咨询我们是否可以恢复,通过远程上去检查,发现运气不错,数据库还没有crash,通过句柄找到被删除文件

由于涉及system表空间数据文件被删除,无法在open情况下直接操作,直接关闭数据库,启动到mount状态,重命名数据文件路径,recover数据文件,open库,恢复完成
参考以前类似恢复:
Solaris rm datafile recovery—利用句柄误删除数据文件恢复
如果数据库已经关闭,需要考虑以下类似恢复方式:
dbca删除库和rm删库恢复
记录一次rm -rf 删除数据文件异常恢复

ssd trim导致fdisk格式化磁盘之后无法恢复

发表于 2023 年 12 月 21 日 由 惜分飞

8个节点的rac,有一个节点有点问题,重装系统的时候,没有选择任何磁盘
20231221191215

结果发现该机器上的所有磁盘都被分区并且加入到centos的vg中了,导致另外7个节点的asm disk的所有磁盘全部异常,磁盘组无法正常mount,在以前正常的rac节点上pvs扫描发现如下结果
20231221191551
对原asm disk(现在被分区加入到vg中的磁盘)进行分析发现所有的ssd磁盘被的以前记录被置空,机械磁盘的数据正常,机械磁盘kfed看到的记录

出现该问题是由于ssd盘的trim操作导致,相关知识补充:TRIM(SATA), Deallocate(NVMe), UNMAP(SCSI)指的是同一类指令，都是为了减少不必要的数据搬移。
原因：
在文件系统中，删除文件并没有真正的删除物理的数据，只是清空了记录表。而此时，对SSD来说，它并不知道文件已经被删除了，只有下次覆写的时候，SSD才能发现之前被删除的文件对应的page是无效的，从而启动GC。然而，如果在此之前发生了GC等数据搬移动作，无效的page仍然会被当做是有效的。重新磁盘分区,重建文件系统也可能触发类似操作
作用：
Trim 只是一个指令，它让操作系统通知 SSD 主控某个页的数据已经‘无效’后，任务就已完成，并没有更多的操作。TRIM 的先进性在于它可以让固态硬盘在进行垃圾回收的时候跳过移动无用数据的过程，从而不再用重新写入这些无用的数据，达到节省时间的目的。
