记一次存储不可读修复

同事告诉我一AIX主机文件系统不可写

引用

# touch llll
touch: 0652-046 Cannot create llll.

怀疑是存储不一致引起，将其umount

引用

# pwd
/oracle
# cd /
# ps -ef|grep smon
    root 22538  9654   0 14:04:42  pts/3  0:00 grep smon
# umount /oracle
umount: 0506-349 Cannot unmount /dev/fslv03: The requested resource is busy.
# fuser -ck /oracle
/oracle:     6726c
# fuser -ck /oracle
/oracle:     6728c
# umount /oracle

采用fsck修复

引用

# fsck /oracle
The current volume is: /dev/fslv03
Primary superblock is valid.
