I am familiar with using dd to create a disk image. dd if=/dev/hda1 of=myimge.img However, is there a way to capture the entire disk image into a file. I have 3 partitions: hda1 / hda2 swap hda3 /home and mbr How can I wrap them all into 1 image file. Thanks, Jerry

I have a 100G disk on an old redhat 7.3 system. Filesystem Size Used Avail Use% Mounted on /dev/hda1 9.6G 2.4G 6.7G 27% / /dev/hda3 99G 6.1G 88G 7% /home hda2 is 2G swap I am trying to back that complete image up on my centos 5 system. I can do the dd if=/dev/hda bs=1M | ssh root at machine 'cat > disk.img' which gets me the whole 100G. As

I am trying to install 6.2 on a machine. I am using PXE as I have done so a number of times. My hard disk is being detected as sdb and not sda. My kickstart config is wanting it at sda. There are no other disks in the unit. It has and SD slot and an esata although BIOS does not appear to have a disable for either of those devices. Is there anyway to "force" the disk to sda ? or find

I am sending an email from my machine devcentos5x64. the transcript below (hangs for 60 seconds) at the line: MAIL From:<root at devcentos5x64.msgnet.com> SIZE=56 AUTH=root at devcentos5x64.msgnet.com The email succeeds - but I am trying to figure out the 60 second delay. Neither email server is busy. Nothing is waiting. the DNS on both machines point to the same nameserver. The DNS

Is there any performance lost in using a software raid array with only 1 disk? I was wanting to use the mdadm monitoring tools to monitor the machines single disk drive for failures and such. Is there any performance hit for such a setup? Some machines have RAID some machines dont (for me) and I was thinking about a common setup. Also then if I want in the future I can actually just add the

To continue here with problems on this compaq v2000 laptop, I put kernel source on a USB disk and plugged it into the v2000. NOTHING IS recognized. I tried to manually mount the disk and nothing either... I thought USB was well established.... I thought trying to recompile the kernel for realtek support might get my networking going... I am stuck??? Jerry -------------- next part

Hi, I was wanting to run the equivalent of "hdparm -Tt /dev/hda" except on a SATA hard disk. What is the equivalent command for an SATA drive? I was wanting to see what kind of speed I am getting on the SATA drive. thanks, Jerry

hi all, I will be migrating my mail server from centos 4.8 to 6 when its released. Basically its just a number of users with their passwords. Their mail is downloaded to their clients and not stored on the server. What is the most sensible or correct way to migrate ALL the users to the new system? Way in the past is was just perhaps copy the /etc/passwd file but I know thats not the case

hi all, running centos 4.7 i686. I seem to have an o pen r elay sendmail server. How do I close it? I have the STRAIGHT centos install sendmail.mc file. Only thing I changed was: dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl so as to allow incoming email and not just localhost. however this seems to relay everyone. I looked at http://www.sendmail.org/tips/relaying but it

All, I am playing with virtualization on centos 5. I took my old redhat 7 disks and created a 10GIG virtual disk, I installed redhat 7. Now I am trying to get the EXACT image copied off of my actual redhat 7 disk so that I know it is the same (including all patches, updates and OTHER things I did to it that I have forgotten about). I booted the redhat 7 image just fine at this point. I also

Hi all, I am trying to extract from the aplay -l output the Card and Device numbers. I had a script that was working but found another motherboard that has an EXTRA word. HDA Nvidia and HDA ATI HDMI is what I am talking about below. how do I search for a line that has HDMI (which I know how to do), then ignore everything upto the device work and take the next field after that? Thanks, Jerry

What does it take to get ztdummy to work correctly? I have a new laptop HP HDX9200. I am running asterisk 1.4.19 and zaptel 1.4.9.2 Zaptel compiles fine. asterisk compiles fine. ztdummy loads asterisk runs. Problem is playback() does not work. So then I stop zaptel, asterisk runs and playback() now works. However, meetme()'s dont work. I need ztdummy I'm pretty sure for that. I am

I am trying to plug a USB 2 device in a USB 3 slot. Nothing is being detected in "lsusb". Is there something special I need to do? I am running centos 5.5 x86_64. I thought 3.0 was backward compatible. Nothing special about my device its an RS232 to USB device. It works in 2.0 slot. Thanks, Jerry

I have a system that is RAID -1 configured as /dev/md0 is /dev/hda1 /dev/hdb1 /dev/md1 is /dev/hdb3 /dev/hdb3 it seems as though /dev/hda has failed....

I know about the commands fdisk to repartion and raidhotadd /dev/md0 /dev/hda1 and raidhotadd /dev/md1 /dev/hda3 (to be ran after the system boots). BUT... how do I now get

I am migrating off of a 40GIG hda to a new 160GIG sda disk. I plan on installing 4.2 from scratch. But after that what is the correct way do transfer all the data from hda (home partition really) to the new sda home partition? I presume there is just a couple files in /etc to restore also. Like hosts, passwd. Anything else? Other suggestions welcome also. this is my first time migrating to a

I was just wondering if there are special tricks people do that compile A LOT on centos? Do RAM disks help or something else I dont about that minimizes your compile time? I presently have and AMD x2 4800+ with 2GIG ram. Just curious if I can reduce any more time out of my compiles. Jerry
