Using Centos 5.2 upgraded from 5.0 using yum on a couple of old Dells in a lab environment. I don't think hardware is part of the problem, just need configuration help. 1: I can boot the diskless client and it come up, but when I do a "mount" command on the client, the output is indistinguishable from the output of the mount command on the server. Currently the fstab in .../root and .../snapshot/<diskless client name> have no entries in them. I set this up using the "how-to" from the Centos web site, I might be missing something. I was wondering if someone could point me to information on how NFS mounts and fstab files work as well as how the "root" and "snapshot" directories work. I'm guessing that snapshot is where you set up the unique personality of each client, while "root" is global to all clients, but I would like info on how it all works together. I could continue to guess and try to figure it out on my own, but my experience has shown that I might get a working solution that is NOT the best. 2: I am running NFS4. I also set up all the diskless clients in an /export directory that is shared with several other exported directories (its a lab, so the devices do double or triple duty). My export file has /exports with the "fsid=0" flag. So, when I mount, I don't have to have "/exports" in the directory string. All is fine until the initial mount done by netboot(?), it issues the first mount command with "/export/diskless/i386/centos5.2/" as the directory string and fails. To work around this, I put a link in that links /export to /export/export and exported /export/export. UGLY I know, but it was the work around I discovered. Anyone know a better way of dealing with this?
