Re: Kill an uninteruptable process

'D' state of the process is the "Uninterruptible sleep" state. This usually mean that the process has requested some operation which should be done by the kernel (for example I/O operation) and that operation was suspended in the kernel for some reason. Usually the operation is suspended until some external event, for example, the interrupt from the harddrive when the read/write operation completed. If the process is in the 'D' state for the long time (e.g. minutes) this means that something wrong happened with the hardware or the kernel data structures (sometimes this is due to some bug in the kernel). There is no way to kill process stuck in the kernel ('D') state. You should either reboot or just forget about that process and allow it to be in the 'D' state indefinitely.

Hi All,

How in the name of sweet Jesus do I kill a process in "D" state.
I have tried the death penalty, kill -9, but it is still listed in ps -aux.
I was installing rpm packages over NFS. I lost NFS during the
installation. I remounted the pertinent NFS directory, no change.
