无法mount文件系统

现象：

重启机器发现 /opt 无法mount
查看/etc/fstab 内容如下：
/dev/vg00/lvol5 /opt vxfs delaylog 0 2
第一步：
# mount /dev/vg00/lvol5 /opt
UX:vxfs mount: ERROR: V-3-21268: /dev/vg00/lvol5 is corrupted. needs checking
第二步：
# fsck -y -o full,nolog /dev/vg00/lvol5
UX:vxfs fsck: WARNING: V-3-20836: file system had I/O error(s) on meta-data.
pass0 - checking structural files
pass1 - checking inode sanity and blocks
UX:vxfs fsck: ERROR: V-3-25432: fsck read failure devid = 0, bno = 79168, off = 0, len = 65536
file system check failure, aborting ...


请问还有啥办法能把/opt mount起来？请指教

lvdisplay -v /dev/vg00/lvol5
先看一眼

看看只读方式能否mount起来，可以的话就备份好数据，之后该干嘛干嘛（比如看看能不能再修复或删掉文件系统重建后导数据）。

PS：建议看看对应的底层磁盘还能否全盘dd读，如果不行的话悬了~
