rm -rf 删除文件出现Device or resource busy错误问题

论文做到疯

论坛的各位老师您们好！本人为刚入模式的新手，最近在装模式的时候，删除文件遇到一些问题，希望各位前辈能够不吝赐教！
$ rm -rf packages
rm: cannot remove `packages/hdf5/hdf5-1.8.19/src/.libs/.nfs00000000000f515a00000224': Device or resource busy
rm: cannot remove `packages/hdf5/hdf5-1.8.19/test/.libs/.nfs00000000000f548000000226': Device or resource busy
rm: cannot remove `packages/hdf5/hdf5-1.8.19/test/.nfs00000000000e33e100000227': Device or resource busy
rm: cannot remove `packages/hdf5/hdf5-1.8.19/test/.nfs00000000000e33e000000225': Device or resource busy


我查询了网上一些回答，查询了运行的进程
$ lsof |grep nfs00000
lt-btree2 24787 yy  txt       REG   0,24   361974  1004672 /home/yy/packages/hdf5/hdf5-1.8.19/test/.libs/.nfs00000000000f548000000226 (ibclusnap:/home/)

将 24787 的进程kill，然后在删除，依旧还是遇到Device or resource busy问题
$ kill -9 24787
$ rm -rf packages
rm: cannot remove `packages/hdf5/hdf5-1.8.19/src/.libs/.nfs00000000000f515a00000224': Device or resource busy
rm: cannot remove `packages/hdf5/hdf5-1.8.19/test/.libs/.nfs00000000000f548000000226': Device or resource busy
rm: cannot remove `packages/hdf5/hdf5-1.8.19/test/.nfs00000000000e33e100000227': Device or resource busy
rm: cannot remove `packages/hdf5/hdf5-1.8.19/test/.nfs00000000000e33e000000225': Device or resource busy


希望哪位懂得老师指出问题所在，谢谢！（tip：本人是在学校的大型机上运行）
