I did not tried it , but when looking in "man mount" I saw, in "Mount options for nfs" section, the following: soft "This option allows the kernel to time out if the nfs server is not > responding for some time. .. Usually it just causes lots of trouble." another option is to use lazy unmounting, which I eventually tried : "umount -l". > after some minutes the unmount was completed.Is there a way to nfs mount a machine so when it is down, it could be unmounted immedaiately without getting trouble (as I am afraid will happen if I use "o=soft" option)? Or is this fear is unjustified > and there is somebody who tried it and it was OK ? Dan In the past I had 1 (one) machine that used soft mounting. I don't recall any problem with it. BUT: 1) Only 1 machine. 2) Low load of the mounted volume. 3) Only a few shutdowns over a long period. 4) I am not sure I tuned the other nfs parameters properly. 5) Probably there are other factors I don't recall at this time. ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
