mount problem

snsd — Wed, 24 Feb 2010 09:37:30 GMT

I have newly installed a RHEL 4 server , this server use NFS mount to connect another RHEL server , but it is strange that the mount will be disconnected in a certain period of time ( between 15 mins and 30 mins ) , I guess the mount is disconnected by the cron job but I can't find it and the old server do not have such problem , can advise what is wrong in my server ? thx

hi,

did you check the network connection between the NFS server and the NFS client ???

look to the syslog and messages file for some errors or strange events.

I found that only mount to a specific local path have this problem , that mean if I mount the remote path to another local path , then it will NOT disconnect , can advise what is wrong in my system ? thx
