General :: How To Identify A HDD In A Server
Jun 6, 2011
Are there any identifiers on an HDD that can be either seen physically on a "sticker" on the HDD, and the same number/identifier could be read with software solutions?
I mean if I see with e.g.: S.M.A.R.T. that an HDD (in RAID) is failing, then I give out the command:
SOMEMAGIC
then I get an OUTPUT, e.g.: 9835923759237489
and then are ther any stickers on the HDD that has a label: 9835923759237489 ? so the hdd that has to be changed could be identified.

I'm currently configuring my nslu2 to reboot correctly, having the Debian Lenny Operating System split over two usbsticks - this is quite difficult, i think.
You see, sometimes it boot, sometimes not. Therefore, I've decided to try UUID naming instead of the default sdX naming system. Maybe udev naming too ... dunno.
Here some person says it is important to do one usb stick at a time. How important is this(?) when I have the OS split over two usb-sticks, not just one?
I have not really used udev for other than renaming ethernet and wlan devices; so some tips on using it for renaming usb-devices would be nice. Is renaming on the grounds of UUIDs the most sensible way, you think?
I have set up the cabling to the nslu2 like this:
[Code].....
Edit: [SOLVED], just go on with naming by UUID if you boot from several memorysticks. Maybe it is preferable to rebuild the initramfs for each edit to the fstab file ...

I have a Red Hat Linux system that does not boot. The boot partition is damaged and files cannot be recovered.
I would like to know how to find out which version of Red Hat was installed from the program/data partition which is undamaged and accessible from Fedora Live CD. I assume this is available in a configuration file somewhere.

I want to grep for $_POST['whatever']. I've done enough googling and trying different things (and failing) to where I felt it appropriate to post here. How do I identify the single quotes as literals? slashes don't seem to do it.

I need to replicate my Ubuntu laptop as a VirtualBox guest. To replicate in the guest the packages currently installed in my laptop, I plan to follow the recipe given here:[URL]What I need now is a way to identify all the packages that have customizations (e.g. changes to config files, etc.)What's the best way to do this? Can dpkg figure this information out and report it?

I am trying to insert a .ko into my kernel and I am getting the 'invalid module format' error. But the kernel object is being generated from or is included in a binary which sets up and populates a driver path when run. How can I tell what architecture/target/anything that .ko is meant for?
I know that I can use the uname and /proc/cpuinfo to see my current info, but I am also not sure what I might need to do to get them to sync up. I am running on a minimal, cli-install of Ubuntu8.10 right now. It's freshly installed (onto a 2GB USB drive) & imaged, so bring on the drastic changes.

I do not know much about parallel computing, but I do have access to a few cpus.I am trying to write a program compatible for multiple cpus, but to do it, I need to ensure unique directories. I have figured out that the time of creation, process id, and cpu id form a unique combination I can use to name files (up to the degree of accuracy of the internal timer).Anyway, I am using perl. I know how to find the process id and I know I can get the time pretty easily, but as I said, I do not know much about hardware or parallel computing. All I need is a way to identify each cpu in the system and I am set for half of my program (the other half is significantly more straightforward and is mainly about text parsing.)
So anyway using terminal, perl, etc., I could access this identification? Or could someone at least tell me the name of what I am looking for? I have seen the words "ip" "MAC" "hostid" and a bunch of other "id" things come up in my googling, but I really cannot figure out which is the one relevent to me

I noticed there're lots of "usb 3-1: reset low speed USB device using uhci_hcd and address 2" warnings in two of our server's syslog. They occur roughly every 20min. The server is a Dell R710 with CentOS 5.4 X86_64 installed. I suspect it's the virtual CD device of the iDrac6 but not sure. How Can I identify which USB device triggering these warning? The related syslog is as following:
Code:
Apr 13 23:32:47 bak2 kernel: usb 3-1: reset low speed USB device using uhci_hcd and address 2
Apr 13 23:42:44 bak2 kernel: usb 2-3: USB disconnect, address 3
Apr 13 23:45:53 bak2 kernel: usb 2-3: new high speed USB device using ehci_hcd and address 4

I'm having some basic doubt! Consider 5 virtual domains has configured under a same server. I mean 5 different domains under same IP. Eg. mydomain1.com and mydomain2.com have IP 208.27.1.89. So when web browser request for mydomain1.com name server return IP address 208.27.1.89. Then browser contact IP 208.27.1.89 on port 80. Here comes my question how does apache know that the browser is looking for mydomain1.com not mydomain2.com. How apache differentiate the request for it's virtual hosts? By the way, what is a virtualhost ?

How do you determine the source and version of a device driver in your linux box? (The wifi driver, for instance.) In windows you can find that info using "device manager". I suppose there is some corresponding tool in linux.

I have two hard drives, sda and sdb. Windows resides on one and Linux on the other. Before I reinstall Linux from scratch, I want to make sure I know which is which so that I don't end up erasing my windows drive. How can I identify which files/directories are sitting on each drive? I.e. how do I find out the mount points of /dev/sda/ and /dev/sdb/?

currently my disk-space is growing very-very fast and in the same time I have a very limited amount of it.Last time I had this kind of problem, I had MySql persistence replication is on and disabling the feature fix the problem. I don't know what happened between now and then, the space is shrinking rapidly (600Meg in couple of days) and I only downloaded files for less than 10Meg in the same period.
Could anybody give me a pointer to a tool that can oversee growing directories or files or maybe a script that able to do this (possibly involving Cron). I try using "Find" but I cannot find any files that are suspiciously growing. I suspect it's a directory that is growing, but I don't know.

Write a script that will take a list of filenames as arguments and output a count of how many of them are regular files, and how many of them are scripts (if the file is executable, it will be assumed to be a script file)
Counts always come back as 0
