记一次HP-UX存储修复

昨天客户数据库由于本地硬盘出现故障，导致交换空间不足，进而导致数据库hang，废了九牛二虎之力终于将数据库切换至备机，由于之前切换都正常，唯独出故障时，切换也同时出问题，影响业务长达2个小时。由于之前数据库物理备份都在1号机上备份，由于切换时，没有将存放备份集的文件系统挂载至2号机，导致备份不能正常运行。由于数据库刚出过故障，此时备份就显得异常重要了。对于HP-UX的故障处理，我其实也是半吊子，既然客户找过来，就尝试着处理。
处理过程其实很简单，简单记录一下
首先尝试mount文件系统

引用

#mount /dev gdata/archlv /backup
mount: /dev gdata/archlv needs to be fsck'ed before mounting
mount: warning: if device /dev gdata/archlv is mounted to another system
                then do not run fsck

提示用fsck修复

引用

# fsck  /dev gdata/archlv
fsck: /etc/default/fs is used for determining the file system type
vxfs fsck: not a valid vxfs file system
invalid super-block
vxfs fsck: cannot initialize aggregate
file system check failure, aborting ...

由于文件系统采用hfs类型，采用fsck修复hfs文件系统类型

引用

# fsck -F hfs /dev/vgdata/archlv
** /dev/vgdata/archlv
** Last Mounted on /backup
** Phase 1 - Check Blocks and Sizes




这一段时间，执行有点长，敲了n个回车
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
121 files, 0 icont, 191561900 used, 58898971 free (11 frags, 7362370 blocks)
***** MARKING FILE SYSTEM CLEAN *****

***** FILE SYSTEM WAS MODIFIED *****

fsck执行成功之后，mount文件系统正常。
