Is there a command to explicitly park the heads of a particular hard drive?
I have a hot swap tray and want to issue commands to sync and park heads before removal.
I've noticed since day one of installing openSUSE that my hard drive makes faint clicking noises quite frequently. At first I thought my drive was bad but after doing an extensive SMART diagnostics test (Passed) and researching on internet I've found that the clicking is actually the heads of my hard drive being put to the rest position via openSUSE's power management. I've confirmed this because if I run this command:
Code:
sudo /sbin/hdparm -B 254 /dev/sda
My hard drive will no longer make any noises and will run silently until the next reboot, as it keeps the hard drive spinning constantly. I'm basically asking (Because I'm paranoid) if the frequent hard drive head movement will reduce the hard drive's life span? I want to find out because I recently upgraded from a 160 GB 5400 rpm WD Scorpio Blue hard drive to a 500 GB 7200 rpm WD Scorpio Black. My old hard drive did not make as nearly as much clicking noises as my new one does, but the clicking can also be heard in Windows (Though not as frequent).
I have been trying to install centos on my hp servers and when i get to partitions my hard drives the OS does not detect any harddrives. I have 4 scsi drives and i believe a intergrated smart array controller.

It's my own fault - the install was running out of room on /, and I, like an idiot, decided to delete some package files under /var/something/archive, thinking they were "old"... I quickly realized they were in fact the new packages being installed... anyway after killing the thing and rebooting it is pretty damn broken (mostly because I can't get networking going so running in dpkg repair mode doesn't do much because, well, I deleted the packages).
I want to copy all the files off my /home and other meaningful partitions onto an external drive so I can just do a clean install.

I have a working fstab entry:

But how do I mount the sdc drive with those options from the command-line without restarting? I've tried to do so with 'mount' utility, but had no luck.
When at the console, what is the command (if there is one) to determine memory usage (used/free) on the hard drive that is being used for one's OS?
View 2 Replies View RelatedI normally use the "locate" command to find files that I have on my local drive. However, if I wanted to do this for an external drive, how would I go about this?
From what little I know about Linux, I'm guessing that it creates a reference file from which it performs the search when the command is typed. If I'm right this is updated at a given interval or when "updatedb" is used?
As the external hard drive is not always mounted is it best to create another of these reference files and have a different command (e.g. locateext) or something? Or is it best to add the external hard drive's location to the list of files that get added with updatedb.

View 1 Replies View RelatedMy parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.

View 2 Replies View RelatedI currently have a centos 4.4 I believe running with a 250GB hard drive. I want to make an image of that hard drive. I have tried removing the drive and connecting it to my windows pc using an adapter that would allow my windows machine run the hard drive as it was a regular external hard drive. Of course windows doesn't reconize that drive since it is linux partitioned. I am thinking that I need to have the hard drive inthe box I am wanting to copy and put in a blank drive in the box that I want to copy to. And boot from a live CD and use cat or dd to copy it. I have seen the commands before bust I am thinking this is the only way. Basically I am wanting to have a duplicate of the drive and build a whole new server that is already all setup.I will just change the host name and assign it another Public facing UP. Is this correct? Oh, and the new server will have different hardware. Might even be AMD or intel different from source or destination.
View 12 Replies View RelatedA section of the hard drive on my laptop is damaged but the laptop has genearlly been running fine as it seems to very rarely touch that section (once every few months). However, when installing some updates the computer has hit that section which means it becomes unresponsive and makes a nasty clunking sound every 10s or so. Because of this I've had to abort the update but now whenever I try to run 'dpkg --configure -a' to sort out the problem caused by the interrupted update I get the same freezing up and clunking. The message that appears when I run the command is adding extension /usr/lib/openoffice/basis3.0/program/mailmerge.py... and then it freezes.

View 1 Replies View RelatedI have a linux box that I'm using as a ADSL router (slack 12.1).Until recently I had two hard drives in it, one for linux, and one for storing movies, music, etc.So, I have just bought another 1,5 TB disk. My plan was to add it to the same mount location: /opt/abram to expand my storage disk, only to come to conclusion that this can't be done. OK, it actually makes sense, if I thought about it I would realise it before. Anyway, what else can I do? Is there a way to add new drive to existing one in a way that would result in one 2,5 TB drive?
I tried it with mdadm, but as it turns out, it's impossible to crate RAID 0 without loosing all the data on sda1 disc.Also, it would be very cool if I could find a solution that would enable me to one day add a new drive to further expend my storage.I'm aware that I could mount my new disk to, let's say /opt/abram/Divx, or /opt/abram/mp3, but that's not the solution I'm looking for.
One of our clients uses a mobile client, which "helo"s with a non-resolvable hostname (which contains the correct IPv4 address in the name but does not resolve). I'd like to be able to config PERMIT "joeblow@mydomain" when the helo-names "*.mobilepool.carrier.net". Can anybody give me a hint how to do this, if it is even possible?Right now it just rejects based on not resolving the HELO name.

View 3 Replies View RelatedAny basic description of how linux assigns drive letters? I understand that a drive letter assignment is not static. If I add a drive between /dev/sda and /dev/sdb, my /dev/sdb will become /dev/sdc and the new drive will become /dev/sdb. I have a hot swap tray and have come into some unexpected behavior. I removed /dev/sde from the hot swap tray and then loaded another drive into this same tray. When I mounted the new drive with options in fstab, it wouldn't mount because the new drive was /dev/sdf, not /dev/sde. Apparently, linux is looking at the id of the drive in addition to it's place in the BIOS chain.
My fstab entry is:
/dev/sde /backups auto noauto,rw,noexec,async,user 0 0
I was avoiding using UUIDs in the fstab so that new HDDs would not have to be "registered" in the fstab prior to use. Is there a way to tell linux (or fstab) whatever drive is plugged into SATA channel X mount to /mountpoint?
By using ISO2USB for CentOS/RedHat I installed with out having to burn A single cd or dvd. Super easy and free from source forge. Link[URL]... Unplug the USB drive and take it to the machine to be installed.Reboot the machine and choose USB boot option in the BIOS boot menu. Choose Hard drive installation method and select /dev/sdb1 as partition that holds ISO images. Use sda drive for installation and choose to review the partitioning layout. In advanced bootloader options, change drive order to "sda sdb". Proceed with the installation.
So easy it should be a tool in every admins box. I hope I saved you some time and headaches.
