I think I saw this many years ago when dabbling with building my own installation from source/scratch. If my memory serves, then what you're missing is /dev/console.

backup scripts
by Andrew Rice 20 Jan '06

20 Jan '06

I was just curious if anyone knew if any good backup scripts...I found one the other day on freshmeat called ibackup which does a great number of things, but I just wanted an idea of what was being used these days. -- Andrew Rice Jr

unsupported kernel vs. yum
by Les Mikesell 19 Jan '06

19 Jan '06

What is supposed to happen to a box running kernel-2.6.9-22.0.1.106.unsupportedsmp now that yum is offering to install the stock 2.6.9-22.0.2.EL version even with the centosplus repo enabled? -- Les Mikesell lesmikesell(a)gmail.com

How would I fix it? When I use knoppix the /dev > system is completely empty because it wasn't used to boot the system. Pop in the CentOS cd, when the boot prompt appears, type "linux rescue". Let it boot, answer the questions it asks in whatever way makes you happy (let it find your installation and probably don't turn on the network). When you're at a root prompt, cd /mnt/sysimage/dev and then ls -l console If it says there is nothing there by that name, create it: mknod /mnt/sysimage/dev/console c 5 1 Type "exit" to leave the shell and reboot, remove the CD and see what happens when it boots this time.

I though dependency tracking was what yum and rpms were for? If I installed the cman-kernel package via yum, shouldn't I get a dependency warning if I try to install the new kernel? I know I would get one if I tried to install the current cman-kernel package on top of the new kernel. -- Bowie

RE: [CentOS] RE: Broadcom NIC Binding under Centos 4.2
by ABOKHALAF, Nassri Abdellatif 19 Jan '06

19 Jan '06

Hello all, again, Still stocked with this NIC binding problem. With Robin's conf both nics work fine in the active-backup config (thanks Robin !) I wanted to go a little bit further & bind both interfaces in an active-active conf. James pointed out the Documentation/networking/bonding.txt. (thanks James!) It states that there is a HA-mode where both NIC'S can work in active-active mode. I've configured the switch to operate in trunk mode for my VLAN and configured my CENTOS box to aggregate the links, but cannot manage to ping my gateway. All interfaces show the same mac addr what is good but, arp -a shows nothing ! Question: Documentation does not say how or if you have to configure de bonding mode for HA in /etc/modprobe.conf. From my point of view it should be mode=6 (balance-alb), but since it does not work I must be wrong! Or should it be left empty ? Any clues ? Could it be the switch ? Thanks, Nassri My conf: Switch - Cisco 3750 interface GigabitEthernet1/0/19 description DNS1 switchport trunk encapsulation dot1q switchport trunk allowed vlan 201 switchport mode trunk end ! interface GigabitEthernet1/0/18 description DNS2 switchport trunk encapsulation dot1q switchport trunk allowed vlan 201 switchport mode trunk end CENTOS BOX /etc/sysconfig/network-scripts/ifcfg-eth0 & ifcfg-eth1 DEVICE=ethx BOOTPROTO=static TYPE=Ethernet ONBOOT=yes SLAVE=yes MASTER=bond0 etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.10.4.27 NETMASK=255.255.255.0 /etc/modprobe.conf alias bond0 bonding options bonding miimon=100 alias eth0 tg3 alias eth1 tg3 < /etc/sysconfig/network > NETWORKING=yes HOSTNAME=dns GATEWAY=10.192.32.254 GATEWAYDEV=bond0 > I have not had time to test this, but the documentation > states that it can be done with some of the other mode=x > numbers, where the mode number represents different types of > bonding ie. round robin, active/standby, etc.. >

star --> tape
by Matt Morgan 19 Jan '06

19 Jan '06

I just got an error using star to send an archive to tape. I know the tape works--I tested it with gnu tar yesterday. But when trying find /home -mount -depth -type f | star -c list=- -z f=/dev/st0 I got the error: star: can only copy files When I wrote to the tape with tar yesterday, tar -zcvf /dev/st0 /home/matt worked fine. And that star command works when the output destination if a file on disk. What do I need? Thanks!
