mounting nfs partition at boot.
by Ajay Sharma 12 Sep '05

12 Sep '05

This seems like another basic question because I always assumed that if I threw something in my /etc/fstab then it will be automatically mounted at boot time (unless I put in the 'noauto' option). But my NFS partition isn't getting mounted, here's the excerpt from my /etc/fstab file, split on the whitespace so it's easier to read: nfs_server:/exports/var/www /var/www nfs rsize=8192,wsize=8192,timeo=14,intr After the server comes up, I can do a simple, 'mount -a' and the partition is alive. Do I need to use something like autofs? I figured I wouldn't need that since there's no reason to unmount this partition. Thanks, Ajay

is there a utility to tell if the monitor is on or off in CentOS?
by Jerry Geis 12 Sep '05

12 Sep '05

Is am trying to find a utility to tell me if the monitor is physically on or off? DPMS is turn off so the monitor will not be automatically turning off - I just need to know if someone has turned off the monitor in an automated way? I thought the VESA standard would have something like that but I have not found it. Does anyone know a way to do this? Thanks. Jerry

Installation problem, possibly RAID
by Edward Diener 11 Sep '05

11 Sep '05

I burned a DVD for CentOS 4.1. I booted from it and everything went fine for the graphical screen installation. I choose separate partitions for my /boot (hde6), / (hde9), and swap (hde12) areas. My /boot partition was ext2 and my / partition was ext3. I installed grub in my /boot partition successfully. I have a Boot Loader, System Commander 8.13 which controls the MBR. The installation then nicely ejected my DVD disk, told me to remove any other installation media, and rebooted my machine. It rebooted into System Commander, I chose the CentOS boot partition, and this rebooted me to CentOS without a problem. CentOS now finished its installation steps, among which was setting up a user account, and attempted to bring up the login screen. My screen went dark, the icon went to a waiting/turning icon for a long time, and I said to myself uh-oh. Finally with most of the screen still dark a small message box appeared with an OK button which said: "Can not start the greeter program, you will not be able to log in. This display will be disabled. Try logging in by other means and editing the configuration file." I pressed OK, my screen went into text mode, and repeated lines of: ext3-fs error (device hde9) in start transaction, Journal has aborted. continued to fill the screen. The only way to proceed was to hit the restart button of my computer. My thoughts of possible reasons for the failure are these. My hard drive is off of an HPT 374 Raid controller, without Raid being actually used on it, and is a 160 GB hard drive, 147 GB formatted. The /boot (hde6) partition starts at approximately the 56 GB boundary, the / (hde9) partition starts at approximately the 76 GB, and the swap drive starts at approximately the 106 GB boundary. Is it possible that I needed to turn on LBA32 as an install option, since there was a screen where I could have checked it but did not ? Is it possible that I needed to tell the install, when choosing my partitions for /boot,/, and swap that this was a Raid controller, event though I am not using Raid with it, since I noticed a Raid button on the Disk Druid graphical screen but used Edit instead to set up my partitions ? Is it possible that CentOS either does not support my Raid controller or supports it in some earlier release which does not work properly even when not using Raid, so that I need to install the proper release of it somehow during the installation process ? I am groping for answers but am really hoping that someone has some knowledge of this problem so that I can use CentOS. Everything went well until the final disaster, and I was keen on getting CentOS to install on my computer. I had previously tried FC4 previously but that wouldn't even get past my graphical screen, failing because I have a Matrox P650 video adapter, but CentOS handled it with aplomb. I am a relatively Linux newbie although an experienced software developer and computer user, so if someone could help me get CentOS running it would really be appreciated. Thank you !

/etc/rc.d/init.d/xfs freezes during boot up
by Ryan Lum 11 Sep '05

11 Sep '05

I have another problem, but I have found a work around. However, I don't know why it works. I was hoping someone could help. With some help from some previous people on the list, I have my CentOS 4 install to work. I had some previous problems with PCMCIA freezing which was caused by my video card. The next thing to freeze was /etc/rc.d/init.d/xfs. My first work around was to linux rescue and remove from the directory which allow me to startup. Although, I executed the script with "xfs start" and it started fine. So, I recopied the script back into the proper directory but added a "sleep 5" at the beginning. The trick worked, but my question is why does it prevent it from hanging.

RPMs for CentOS
by Edward Diener 11 Sep '05

11 Sep '05

When looking for RPMs for CentOS 4.1 outside of the yum CentOS repositories, do I choose the version of a product which says for FC4, or what, if there is no specific version mentioned for CentOS ?

NFSv4 "Missing" Data on Clients
by Jason McCormick 11 Sep '05

11 Sep '05

Hello all. I converted my server from Fedora Core 3 to CentOS 4.1 and I've been slogging unsuccessfully through an NFSv4 problem. I'm using the same configuration for NFS that I had in place on FC3 that worked. On the server, I have the following data structure: /data /data/archive /data/pictures /data/music Each is a separate ext3 filesystem mounted with rw,acl. /etc/exports presents all of these filesystems properly: # exportfs -v /data/pictures 172.17.17.0/27 (rw,wdelay,insecure,root_squash,no_subtree_check,anonuid=65534,anongid=65534) /data/archive 172.17.17.0/27 (rw,wdelay,insecure,root_squash,no_subtree_check,anonuid=65534,anongid=65534) /data/music 172.17.17.0/27 (rw,wdelay,insecure,root_squash,no_subtree_check,anonuid=65534,anongid=65534) /data 172.17.17.0/27 (rw,wdelay,insecure,root_squash,no_subtree_check,fsid=0,anonuid=65534,anongid=65534) All the the appropriate services are running (portmap, nfs, rpcidmapd). I've tried this with and without iptables enabled so I've ruled out firewall issues. When I mount the filesystem on the client, none of the "sub" mountpoints shows its content: # mount -t nfs4 server:/ /mnt/server # ls /mnt/server archive lost+found music pictures # ls /mnt/server/archive # Except that there's 15G of data in /data/archive on the server. File operations in /data that don't traverse the server-side mountpoints work fine (i.e. I've created /data/foo and performed reads and writes in there on the client). I know that this setup worked in Fedora 3 so I'm unable to account for the operational differences. Anyone have any thoughts? - Jason

Yum issues with swatch
by Ed Morrison 11 Sep '05

11 Sep '05

I am trying to install swatch via yum but it doesn't recognize swatch as being available. I have tried various naming conventions such as swatch-3 etc but still no go. I have Dags repo in yum.conf and I see it listed there on his webpage. In addition, I did a yum search swatch and still nada. Anyone have an idea as to why it will not install? I'm running CentOS 3.5 Thanks, Ed
