[Bug 1328156] Re: Problem with directory listing of nfs filesystem

[luckyrings]

Concering to RPC Info and Wireshark investigation version 3 is used by
the server:

user at server /var/log $ rpcinfo -s terastation | grep nfs
    100003  3         tcp,udp                          nfs         unknown

Question is if it is client problem, or not.

Title:
  Problem with directory listing of nfs filesystem

Status in “nfs-utils” package in Ubuntu:
  New

Bug description:
  I have problem with NFS file systems which have been mounted on my
  client computer with Ubuntu 12.04.4 LTS. The server is a non Ubuntu
  distribution (TeraStation TS-WXL / FW 1.63).

  After mounting the exported file system on my Ubuntu and doing a
  directory listing, the listing is not possible.

  It shows only Input/Output error.

  Everything else like addressing single file (with rm, cp....)  or
  changing directory command works fine. I found out that the error
  appears only when a certain amount of files together with certain file
  name length has been stored in the affected folder.

  Here some example output when the error appears. The user / server /
  path has been anonymized.
