Is there a command to determine of a device supports IO Fencing?We are trying to run a Sybase cluster that shares storage. I'm sure the device supports fencing, but don't know how to show that it does.

Can I try out redhat clustering in vmware with vm machine?
I am trying to create a cluster using conga and i am stuck at creating a fencing. I have no idea as what fencing device i have on my server or what fencing method to choose in creating the cluster.

Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:

I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:

When I run apps like mplayer to use my web cam it uses /dev/video#. For reason unknown to me this number changes and is usually either 1 or 0. I have looked on the Internet after struggling to find how to know which /dev/video device is used. So far I can only presume I have used the wrong terms to find how to determine which device the web cam is using.

'Determining IP information for eth0... failed; no link present.'
I'm curious to know how, after booting up, I could set the IP information for a wireless device, wlan0, manually. Another way of putting this questions is: if CentOS is able to determine IP information for a network device on bootup, what settings is it configuring exactly?
I'm currently running Ubuntu (w/ GRUB) and Windows XP. I'd like to remove Ubuntu and run the recovery on Windows XP because it has started not running correctly. The computer is about 5 years old and I figured I'd just wipe it clean and start over (read: remove Ubuntu and reinstall windows via the recovery console).
I intend to follow the tutorial here: [URL]
However, I'm confused about determining the boot device number for Windows. I've run "sudo fdisk -l" and I can identify the windows drive in the list it says:
Device: /dev/sda1
Boot: *
Start: 1
End: 19352
Blocks: 155444908+
Id: 7
System: HPFS/NTFS
Am I looking for the 7, the 1, or something completely different? This is also the first partition on the list.
sda2 (id: c) is a FAT32 drive. I think this is the recovery partition included on the HP desktop.
sda3 (id:83) is Linux
sda4 (id: 82) is swap
I just need to run fixmbr.
I'm writing a bash script that needs to know whether or not a device node is part of a RAID array. I'm just curious if anyone knows of a good way to determine if a device node is in a RAID array. I know that you can run mdadm -Q or mdadm --examine on the device node and that will tell you. But I don't want to rely on screen scrapping and would rather have something that would return a boolean. Any ideas?
View 2 Replies View RelatedIs there a way to determine the IO size that is being used for reads and writes to an attached storage device? I am trying to pattern the IO sequences to storage. I have seen mentions to max_sectors_kb but the notes indicated that changing this value did not change the IO size to the storage.

I got a machine with RedHat Enterprise Linux 5 installed. I set the ifcfg-eth0 as following:
Code:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Ethernet
when the machine rebooted, eth0 has the ip address 192.168.24.234. But if executing 'dhclient', eth0 will get the ip address 10.200.34.208, which is my expected ip address. I'm not quite familiar with networking things. I don't know what's going on there. Why should I need to execute 'dhclient' to obtain the expected ip address? Is there any way to obtain the ip address 10.200.34.208 right after host boot?
I have installed Ionix vCM onto a Red Hat Linux box. It correctly communicates with the collection server if I use the Ionix certificate. However, if I use a self-generate certificate, communication fails.
(1) How do I determine which PKI certificates are resident on the Red Hat box?
(2) How do I manually install a PKI certificate?

View 3 Replies View RelatedOn one of my servers the "free" command tells me that a lot of swap space are in use. What I'd like to do is to determine which processes have been swapped out. I tried issuing "top" and sort by the "swap" column, but this doesn't seem to provide correct values - when performing the same excersize on another server with close to no pages swapped out, the sum when adding the swap value for each process greatly exceeds the swap usage reported by "free". So how do I go about determining the swap space used for individual processes?
