Weird NFS Problem: Input/Output Errors, etc.
Since last week I've had some really weird problems with NFS,
but I do not know where do search for the problem. Maybe some
of you have com across somethink like the following:
The problems occur on three NFS Clients (two of them diskless)
while the Server shows no problems with the same files. Even the
Servers Logfiles are clean ...
After rebooting the Client, the Files are accessible again, but
other file accesses fail. Apt and dpkg fail during
each ~ 3rd installation, showing errors like "Input/output error"
or
dpkg: error processing /var/cache/apt/archives/slang1_1.4.4-3.1_i386.deb
(--unpack): unable to create `./lib/libslang.so.1.4.4': Too many levels of symbolic
links
while logging to the client's sylog:
Aug 12 17:01:54 hobbes kernel: nfs_refresh_inode: inode 1097449706 mode
changed, 0120777 to 0100000
Another Example:
bb@hobbes:~$ ls -l /usr/share/man/man1/
ls: /usr/share/man/man1/gvim.1.gz: Input/output error
ls: /usr/share/man/man1/gvim.1.gz.dpkg-tmp: Input/output error
ls: /usr/share/man/man1/gview.1.gz.dpkg-tmp: Input/output error
ls: /usr/share/man/man1/rgvim.1.gz.dpkg-tmp: Input/output error
ls: /usr/share/man/man1/rgview.1.gz.dpkg-tmp: Input/output error
ls: /usr/share/man/man1/ex.1.gz.dpkg-tmp: Input/output error
ls: /usr/share/man/man1/rvim.1.gz.dpkg-tmp: Input/output error
ls: /usr/share/man/man1/rview.1.gz.dpkg-tmp: Input/output error
ls: /usr/share/man/man1/view.1.gz.dpkg-tmp: Input/output error

At the same time, the following errors were logged:
