- We are running Netware NFS v1.2 on a 3.11 server and
- are experiencing some odd problems. First, I should
- say that this is no ordinary server. It has appoximately
- eight thousand user accounts, and each user has a
- directory containing five to ten files. This server
- sees a pretty large and constant load. There are
- frequently a hundred or more simultaneous users. The sys
- volume containing all these accounts is a nearly full 1G
- volume with an NFS namespace. We mount the user subtree
- from this volume onto a Sparc 2 running SunOS 4.1.3.
- On the Unix side, we get very inconsistent results from
- stat system calls and ls's. If a directory is listed
- twice within the space of a few seconds, the permissions
- and owners of files are likely to be different from one ls
- to the second. A stat on a file may return an error
- for non-existance and then return a good return code
- for the same file even though there is NO chance that
- the file changed status. This occurs most often when
- listing very large directories (there are some directories
- on this server with thousands of subdirectories), but it
- also happens on small directories when the server is
- heavily loadedWe were counting heavily
- on using this product, and are loathe to give up on
- it. Has anyone else seen similar things with this
- product? Is anyone else working it as hard as we
- are trying to? Does anyone have suggestions for things
- we can change about in the export or mount parameters
- (it is currently mounted rw,hard,intr,bg,timeo=y,
- retrans=6,rsize=8192,wsize=8192)? Thanks in advance
- for any help you can offer.
