There really ought to be, shouldn't there? What is it that reboot does to unmount the file system that we can't? Well, actually, .... I find that reboot sometimes does no better. *it* hangs during shutdown when trying to unmount NFS volumes. Then I have to use a hardware reset to accomplish a reboot. And it ends up spending an age fscking and recalculating quotas. In its doomed attampt to make sure everything is shut down properly, it ends up making more damage necessary. I get this problem when the NFS server goes down and the clients are still active. Really, they shouldn't wait forever. Since my server is an AMD-64 with nvidia-driver instability, this happens way too often. I've noticed that if the NFS server goes down and is rebooted everything is fine, provided none of the clients do *anything at all* to it while it is down. But if they try to do anything at all woth the NFS-mounted system, eve, unmount it, they hang forever. -- hendrik > > > Greetings, > Frank > > -- > Frank Blendinger | fb(at)intoxicatedmind.net | GPG: 0x0BF2FE7A > Fingerprint: BB64 F2B8 DFD8 BF90 0F2E 892B 72CF 7A41 0BF2 FE7A -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
