Duplicate computers
by centos＠911networks.com 10 Feb '06

10 Feb '06

Hi, I need to do an install on 12 identical computers. Once I have done the install on one of them, is there a simple way to duplicate the drive to the next computer. I do not have access to Ghost, any suggestion? -- Thanks http://www.911networks.com When the network has to work

quick question on yum
by Jerry Geis 10 Feb '06

10 Feb '06

I think I saw where up2date is going away (perhaps browsing FC5 new and changed items) "yum update" will ask me if it wants to proceed. I have not seen a way to not have the prompt for Y/N? Is there a way to not prompt and just go ahead and do the update. Thanks, Jerry

Mount LVM
by Simone 10 Feb '06

10 Feb '06

Hi guys, sorry if this is trivial, but I have been googling a couple days and already compromised a test disk trying to figure this out, so I thought it is time to ask for some advice. I have a disk that comes from a clean and working CentOS4.2 install, and I am trying to use an external usb to ide converter to mount it on another workstation with CentOS4.2. I am trying this to better understand how LVM works, in the case of a future disaster/recovery scenario. Simply trying to mount it: mount -t ext3 /dev/sdc2 /share/ mount: wrong fs type, bad option, bad superblock on /dev/sdc2, or too many mounted file systems fdisk -l shows /dev/sdc1 * 1 13 104391 83 Linux /dev/sdc2 14 7476 59946547+ 8e Linux LVM and in fact, /dev/sdc1 is automatically mounted. vgscan reveals only my current volume group Found volume group "VolGroup00" using metadata type lvm2 (mount --> /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)) lvmdiskscan --> /dev/sdc2 [ 57.17 GB] LVM physical volume ---> This being the volume I want to mount lvscan detects only the volumes on my system ACTIVE '/dev/VolGroup00/LogVol00' [112.34 GB] inherit ACTIVE (root) '/dev/VolGroup00/LogVol01' [1.94 GB] inherit (swap) If I run "vgchange -a y" --> 2 logical volume(s) in volume group "VolGroup00" now active, the ones in my system. I went through LVM Howto, and also tried to follow a few "mount/recovery procedures" with the only result of compromising the other test disk. I think this the problem is that the vg on my system has the same name of the one on the external usb disk, but I am not sure of what result would have running vgrename, vgcreate or lvcreate on the data, so I'd rather wait for some advice. Any help appreciated

mkinitrd trouble
by Aleksandar Milivojevic 10 Feb '06

10 Feb '06

I've just updated one machine from 4.0 to 4.2. The trouble is, the new kernel doesn't want to boot (2.6.9-22.EL, also tested 2.6.9.22.0.2.EL). Usually, manually recreating initrd file solved this problem in the past for me. But not this time. Playing around, I also noticed that if I rebuild initrd for the old kernel, then it also fails to boot. The only way to boot it up is using the original initrd image created when the system was initally installed. The machine has two volume groups, sys and backup. The sys volume group contains logical volumes with operating system, the backup volume group just holds some temporary application data. Looking at what goes on the console during boot, the only difference between what happens is initialization of LVM (nash script in initrd image). With the old one, it reports it has found two volume groups (backup and sys, in that order), and then that it actived all volumes in both of them. With new initrd images, it reports it has found two volume groups, but activated only volumes from volume group sys. The root file system is part of sys volume group (so its logical volume should be active). The backup volume group contains file system with some data, and it's presence (or non-presence) theoretically shouldn't affect bootability of machine. However, booting still fails with root file system not mounted and of course kernel panic since it can't find init. I've attempted doing several things (vgchange -a y, vgcfgbackup, checking the files it created, vgcfgrestore, then recreating initrd images). But nothing helped. I guess all needed device driver are correctly loaded, since it was able to detect volume group (and both volume groups are on the same RAID controller). Running mkinitrd in verbose mode looks fine too. Any help would be greatly appriciated. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

OOT: itegno gsm modem + gnokii + playsms
by Fajar Priyanto 10 Feb '06

10 Feb '06

Hi all, sorry for the OOT. I've been trying to setup a sms gateway for a couple of sleepless nights now. I use Itegno 3000 USB gsm modem, gnokii sms manager, and playsms a web interface for sms http://freshmeat.net/projects/playsms/ on FC4. Here's what happen: 1. Using minicom, I can send sms 2. Using xgnokii (x interface of gnokii), I can send sms 3. Using playsms, I CANNOT send sms, it got stuck in playsms queue with pending status. 4. This is interesting: using Sony Ericsson K700i cell phone + gnokii + playsms, I CAN send sms. Neither using gnokii from livna nor source solved the problem. Has anyone try setting up a sms gateway using itegno + gnokii + playsms? Could you pls give me some hints?

Swap & logout
by Sam Drinkard 10 Feb '06

10 Feb '06

Ran into something tonight I've not seen before. The system has been up for 20 days, and has not missed a beat of any sorts, even when getting beat on at a decent level. What my concern is, tonight I attempted to log out so X would restart, and from the looks of all the stuff on the screen (which never did reload gdm) was chock full of statements where swap had been exhausted, and processes were being killed off. The only way I was able to recover was to login via another machine and kill -9 the gdm process. Could not access any of the VT's at all. What I'm wondering is if swap is not being released, rather if processes are not being moved out of swap when the load decreased. From the looks of top top - 21:20:59 up 19 days, 23:07, 5 users, load average: 0.22, 0.24, 0.17 Tasks: 146 total, 1 running, 145 sleeping, 0 stopped, 0 zombie Cpu0 : 1.7% us, 0.3% sy, 0.0% ni, 98.0% id, 0.0% wa, 0.0% hi, 0.0% si Cpu1 : 0.7% us, 0.0% sy, 0.0% ni, 99.3% id, 0.0% wa, 0.0% hi, 0.0% si Cpu2 : 0.0% us, 0.0% sy, 0.0% ni, 100.0% id, 0.0% wa, 0.0% hi, 0.0% si Cpu3 : 0.7% us, 0.0% sy, 0.0% ni, 99.3% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 2055916k total, 1199952k used, 855964k free, 50464k buffers Swap: 1052216k total, 64020k used, 988196k free, 781740k cached There seems to be plenty of swap free, even tho the cache is still OK. I didn't have the presence of mind to run any other tools to see the system behavior. Believe this is the first time I've had to kill gdm to reload and recover. Perhaps there is some tuning or tweaking I could do? The main processes are the wx model, which uses anywhere from 1.2 to 1.4G of memory, plus all the normal stuff you find on a workstation. Suggestions anyone? Thanks.. -- Sam Drinkard <sam(a)wa4phy.net>

CentOS friendly groupware
by Chris Mauritz 09 Feb '06

09 Feb '06

Just wondering what the consensus is around the list for a usable groupware product. It doesn't have to be as "fancy" as the integration between Outlook and Exchange...just simple calendaring, ToDo lists, document sharing, contact manager, etc. Has anyone tried opengroupware? It seems to do what I need, but doesn't support Chinese (which would make life a lot easier for my folks in China). Any suggestions would be greatly appreciated. Cheers,

poweroff when returning from standby
by Adrian Coman 09 Feb '06

09 Feb '06

Hi, I managed to make my Packard Bell EasyNote to standby (suspend to RAM), but I still have a problem: when I press the power button to return from standby, the system is restored but is immediately entering the poweroff procedure ... I don't know why. It's like I pressed the power button twice, which I didn't. Do you have any ideas of what could be wrong? Thanks, Adrian
