NFS - changing IP address after startup
Hello, Is it legal to change ip address & mac address when working with NFS, and after linux finished startup ? It seems that in such case, NFS can get stuck, right? Thank you, Ran

I think yes, NFS can't tolerate changing IP, both in client and server side. I remember it, well not exactly identical case, when my NFS server dies. In that case, the NFS client box just hung....I guess it waited for somekind of acknowledgment....but none coming. IMHO it gets worse when you use "sync" option in NFS. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com

Hi Mulyadi, Thanks for the reply. That is also what I remember from past experience, I just did not find any documentation about it, so I wasn't totally sure that there is such limitation/requirement with regads to NFS. Regards, Ran

So far, I also failed to find the documentation that exactly tells this kind situation of situation. Well perhaps the only way to be sure, as always, is by checking the source. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
