I am a user (without root priviliges) on a small academic
cluster of about 15 homogeneous linux PCs. They are supposed to share the file system which contains the user's home directories. I am a linux newbie and know nothing about linux networking.
After the cluster came online about 2 weeks ago, and I moved my hoemspace to the server there, I started having strange problems, mostly when saving files in applications.
1)Netscape frequently gives "Error saving bookmarks file."
2)Emacs frequently gives "I/O error" when I try to save a file.
3)When I compile a file using g++ -c, the compiler often reports a "no space left on device" error. I don't believe that the disk space available to the compiler is insufficient.
4)When I try to "more" a file which I have recently saved in emacs, the result is the same as "more"ing an empty file, i.e. exists but has no contents. However, ls -l command on the same file reveals that the file is in fact 23KB etc.
5)When I reload files, sometimes I find mysterious control characters appear in files which I had been working on, obliterating portions of the text which I had entered.
The frequency above effects depends on which machine in the cluster I started the application from.
Please explain to me what is the likely cause of and remedy for the above. What exactly should I say to my sytem manager? I'm not sure that he is an expert either.
Thank you very much
