I don't know why, but processes in the D state (disk wait) are counted in the load and ACTUALLY slow the apparent running of other processes (I've seen it several times, whenever our file servers is disconnected). I work with quiet old kernels (2.4.7-2.4.22) so may me it is better in newer kernels. > > , and there is no way to umount it, > > So what, exactly , is 'umount -l' in that sense? Can it be of any use? I meant you can not force un-mount NOW (like umount -f). The `umount -l' will only unmount it only when the server will work again and all open files on that NFS mount are closed (It may not work at all if a process opened a file on the NFS before the `umount -l' and tries to open another file after it (blocking, until it succeeds), without closing the 1st file. > > OTOH, when it comes up again, any waiting I/O completes successfully > > as if no interruption occurred.
