extendfs的时候,远程连接中断了,结果导致文件系统无法mount上
#fsck -F vxfs -o full /dev/xxxx
vxfs fsck: not a valid vxfs file system
invalid super-block
search for auxiliary super-block? (ynq)y
alternate super-block not found
vxfs fsck: cannot initialize aggregate
file system check failure, aborting ...

比较麻烦。我处理过一个类似的，建议重启系统后重新mount
