List-Post: List-Help: List-Subscribe: , List-Archive: It seems soft mounts only work if the NFS server is alive and not completely offline. We have some hardware issues with one of our NFS servers. So to keep things moving we use soft mounts, but when the server gets powered down and rebooted, soft mounts are meaningless. The processes are not killable, until the server comes back (regardless of timeout) From what I understand the 'intr' option is also flawed in this same manner. Am I just seeing things or is this a serious problem? I also do not like the argument that NFS insists on keeping the processes open even if the server is down for data integrity purposes. I should be able to safely turn on that insane behaviour. I personally need the FS error as my mail delivery method is NFS/FS safe. On a side note, what the hell is with NFS caching?!? Without it I get about 700 _KB_ per second, with it I can get 88 _MB_ per second. I have no tested this with 2.6, this was with 2.4. But on the flip side, I have to sometimes 'touch' directories to have them re-read. I would love to disable it. Thanks in advance for any insight you can give me. -reid ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
