fergie - finally
mmmmmmmmmm
ever since i was a baby girl i had a dream
cinderella theme
crazy as it seems
always knew that deep inside that
there would come that day
but i would have to wait
make so many mistakes
i could'nt comprehend
as i watched it unfold
this classic story told i left it in the cold
walking through unopen doors that led me back to you
each one unlocking more of the truth
i finally stopped tripping on my youth
i finally got lost inside of you
i finally know i needed to grow
and finally my mate has met my soul
finally
now my destiny can begin
though we will have our differences
something strange and new is happening
finally
now my life doesn't seem so bad
its the best that i've ever had
give my love to him finally
mmmmmmmm
i remember the beggining you already knew
i acted like a fool
just trying to be cool
fronting like it didn't matter
i just ran away
put on another face
was lost in my own space
found what its like to hurt selfishly
i was scared to give up me
afraid to just believe
i was in a jealous, insecure, pathetic place
stumbled through the mess that i have made
finally got out of my own way
i finally started living for today
i finally know i needed to grow
and finally my mate has met my soul
finally
now my destiny can begin
though we will have our differences
something strange and new is happening
finally
now my life doesn't seem so bad
it's the best that i've ever had
gave my love to him finally
mmmmmmmm
finally, finally
finally
now my destiny can begin
though we will have our differences
something beautiful is happening, happening
finally
now my life doesn't seem so bad
it's the best that i've ever had
give my love to him finally
ohhhhhhh, finally, finally, finally

发现当使用“快照”备份“lv”之后，在往服务器里写入文件时（大文件，内网快速写入），发现有kcopyd进程时常阻塞，系统负载达到2/3/4（在2、3、4之间徘徊，具体硬件应该会有所不同，仅供参考）之高，搜索kcopyd相关的信息了解到跟lvm中快照有关。

将系统中的删除之后，就不再有kcopyd阻塞的情况，并且系统负载也降了下来。
