Got a strange one here: Customer reports that on his V1.4 ASE Digital UNIX V4.0a system more often than not he is unable to fail his NFS services over because it thinks the device is busy! Not always the same service (he has several). Once he reboots then all will be well for a while. I have got him to force a crash, and looking at it with dbx and it's bretheren I find that a couple of the domains seem to have VREG type VNODES which have v_usecount =1. Since vrele() will look at the usecount to decide whether to release the vnode I guess this is not releasable. I also note that the V-flag field is 4096 (decimal) which I think pans out to VSYSTEM. Implying this is a vnode being used by the system. My question: What might be associated with this vnode? What might I do to find out why I have several of these associateed with a couple of domains? I am postulating that this is probably a configuration problem, because he had the same issue (so he says under V1.3 with V3.2D of UNIX). He upgraded just before Christmas. Any suggestion? All Firmware seems up to date, ( I am going to get him to use UNICENSUS, to be absolutely sure!) and the SCSI termination is supposedly correct. Any pointers of help much appreciated. Many regards Idris

It might be good to run lsof on the system just prior to the relocation... my first guess is that he does not have the mount points correct, or has a system using the real mount point rather than the NFS loopback point. lsof can be found via http://www-unix.zk3.dec.com/tuning/tools/tools.html | |||||

In the meantime customer has got hold of lsof himself and has tried it It does not show anything open in any of the filesystems which he is trying to fail over! What does the system need to keep open? Could this be due to losing touch with underlying disks ? Or something? regards and thanks idris | |||||
