[CentOS] Centos NFS-Utils
Just wondering, We have been using RHEL 6.1 for a while and its NFS-utils support the fsc option for caching.

[CentOS] nfs timeout
hi, I use automounter to mount to many hosts /net//dir When the hostname is unavaliable it seems NFS gets stuck. I would like to set a NFS timeout (say 60 secs). If not available then error.

Re: [CentOS] compile paramaters
Thanks Phillip.

No, thats not what I meant. Instead of installing the RPMs on 40+ servers and having to get the latest version of Numpy (usually we want to bleeding edge), I prefer to have a good version of Python in /nfs/mountpoint and have all my clients mount there. -- --- Get your facts first, then you can distort them as you please.-- ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] NFS hard mount
Thanks for the detailed response. My problem is we have many NFS servers and clients. The client mounts to the servers using /net/serverA/dirA. When server A is decommissioned all the clients hand on `df`. I was wondering if there is a clean way to unmount the server instead of rebooting clients (100+ clients). I am try doing a lazy unmount but that doesn't seem to fix the problem.

[CentOS] maximum number of mounts
What is the maximum number of NFS mounts per client? I have an instance where there are over 400 mount points using autofs. I was wondering if there is a downside to that. -- --- Get your facts first, then you can distort them as you please.-- ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] maximum number of mounts
Thanks for the response. I am using TCP mounts. The reason for 400 mounts is because we have several hundred storage servers and use automount to mount them up. The data is scattered all over the place thus the extremely large mounts.
