Hi, My guess is that your ramdisk experiments have corrupted the filesystem. Perhaps you have removed files that are actually needed by the login process. As a suggestion, in future, take a COPY of the NFS file system & experiment on that. It is possible that the reboots (if not controlled shutdowns) might be the cause. You didn't say why you needed to reboot - if the host had crashed then it suggests there may be hardware issues, which in turn could lead to file corruption. (Check the contents of /var/log/messages* to see if there is anything wrong. You can sometimes find disk related mesages that may indicate a fault - a lot of controller resets or I/O errors for example). If you suspect the hardware then download the Ultimate Boot CD (http://www.ultimatebootcd.com/download.html) and run some tests. To fix the problem simply take a new copy of the file system from the MV installation and start again.

My host machine was rebooted a couple of times during this experiment. After then I tried to remount the NFS and now I cannot go beyond the login prompt. The system is locked at this stage - and I'm not able to decipher the error message " 10.100.135.50 login: root /bin/login: error wh " Could some one please tell me what is wrong and why this could happen.
