Hi, I'm trying to repair a remote system using the Live CD. I have VPN access to the subnet where it lives. An onsite person is booting from cd, and running a small script I provided to tweak the default firewall rule set to allow incoming ssh, and set a password for the centos user and start sshd so far so good I can remotely access the system. the problem is the live cd environment is

I am the system administrator. I have a system that was built with a default install which resulted in everything in a single file system except for /boot wrote some scripts to split out: /home, /usr, /var, /opt, and /tmp to separate file systems/logical volumes it looks like it ought to work, There's plenty of space in all the filesystems and I can log via ssh and have write access in my

Hi, I want to rename some volume groups and logical volumes. I was not surprised when it would not let me rename active volumes. So I booted up the system using the CentOS 5.5 LiveCD, but the LiveCD makes the logical volumes browsable using Nautilus, so they are still active and I can't rename them. Tried: /usr/sbin/lvchange -a n VolGroup00/LogVol00 but it still says: LV

Please excuse a wee bit of cross posting here. It seems that the questions list may not be the appropriate place for this as I've found a number of unanswered posts involving this topic. My FreeBSD workstations are setup with pam_ldap to a centralized openldap server for authentication. This works perfectly for native FreeBSD applications. What I'm running into an issue with are Linux

Hi Folks, Anybody have any recent experience building a small cluster that combines GlusterFS and Xen (with bonus points for a Debian environment)? We''re getting ready to shift from a 2-node Xen/Pacemaker/DRBD environment to a 4-node environment - and I''d really like to be able to create/migrate/failover/delete VMs transparently across all 4 nodes. Seems like Gluster might

Hi, I''ve been building up a new HA system, running Xen on DRBD devices. Configuration this applies to: Debian Lenny xen-linux-system-2.6.26-2-xen-686 package |**|drbd8-modules-2.6.26-2-686 drbd8-modules-2.6.26-2-xen-686 As I''ve been building the system, I ran into an interesting problem, with two symptoms: 1. running VMs would come back up after a reboot, but would hang on

OK, it seems that the kernel I have (stock CentOS 4.7: 2.6.9-78.0.22.EL i686) seems to gronk the nVideo SATA controller in AHCI mode. It is NOT able to deal with the SATA DVD Burner I have. It is a "Sony Optiarc DVD Burner with LightScribe Black SATA Model AD-7241S-0B LightScribe Support". Is there some special magic I need to do? Here is the relevant bit from the boot up (SATA ports

My friend has an external sata hard disk, and likes the hot-plug feature. However, that works only if the appropriate sata setting in the motherboard bios is set to AHCI (IDE compatibility and RAID are two other options, but hot-plugging doesn't work with them). The machine has WinXP atm, while Linux is about to be installed in the following couple of days. Now, on wikipedia I read that

Howdy, I may be approaching this problem entirely wrong, or not. Was hoping for a little guidance one way or the other. I've got this AS/400 with gobs of unused file storage on it that I want to share across as a file server to a FreeBSD box. The AS/400 side of things supports NFS and kinda pretends to be a Unix like machine in this role. Users will be booting from diskless clients

Hi all, I changed a bad disk (automaticly disabled from software raid1 and system for I/O error) in one of our servers and now have problem with adding new one to system without reboot. Does anybody have an experience with this? Or is it possible? :) We're using hotswap AXX6DRV3G for 6 SATA disks from Intel connected directly to MB (S5520HC from Intel too). There is AHCI as driver (enabled in

Hello, I am trying to install Centos on sata ahci. The installer first waits few minutes while loading ahci module. Then, the installer cannot detect any disk during the partitioning phase. What might be the problem? I have switched to IDE in bios and it still is the same. Best regards, mjb

Hi, There's a RHEL5 system somewhere across the internet with a trashed root file system. I have VPN access to the subnet where it lives. But the system is not talking to the network. The current plan is having an onsite person boot from a CentOS Live CD, copy a small script to configure networking, set a password for the centos user, start sshd, and tweak the default firewall to allow

Hi Folks, I''ve been getting just a little fed up with the state of Xen on Debian Lenny - there are a couple of known bugs that lead to periodic kernel panics - but fixes haven''t made it into the Lenny distribution. I''m sort of waiting to see how things shake out with Debian Squeeze, when it becomes stable, but... I''ve been noticing that Suse (both the

Been trying to puzzle through a firewall layout here involving E-Mail. Would have thought this was a more common kind of scenario, but I haven't been able to Google me up an answer to this one. At present I have an SMTP server (Postfix) in my DMZ that is simply re-routing mail into my secure network. This is a less than optimal setup simply due to having to allow traffic from the DMZ

I have one HP Proliant DL320 G5p, where for some reason, the AHCI mode is not enabled. According to server specs, it should have AHCI/NCQ capability, but ata_piix module gets loaded during bootup, not ahci module. Any ideas how to enable AHCI mode? lspci output: # lspci 00:00.0 Host bridge: Intel Corporation 3200/3210 Chipset DRAM Controller (rev 01) 00:01.0 PCI bridge: Intel Corporation

Hey folks, So what's the word on AHCI and bios drive geometry? I'm having a real pain of a time trying to get some 750gb sata drives running on my FreeBSD7 box in AHCI mode. It doesn't seem to matter what disk geometry I suggest to sysinstall, something complains of an invalid disk upon booting it. Actually, in AHCI mode the bios screen doesn't report any information on

Hi, I'm trying to install an old fujitsu siemens econel 50 server. It uses an Intel chipset with ICH6R sata subsystem known as fakeraid. I have configured a Raid 1 with two 160GB hds. FS and Intel both provide a driver called megaide on a driver disk to use fakeraid and here is the problem: - The readme tells me to install with the "nostorage" kernel option and I can load the

I'm having trouble getting a Centos installation to boot on a system with hdd's hanging off an AHCI hba. Long ago, I posted about only seeing four of the six sata ports on my asus server board. According to research I've done since then (I now need the ports!), the solution is to enable the AHCI bios, which turns on NCQ and the last two ports. The already installed system does not
