I've looked high and low but I haven't been able to find any example of what I'm currently experiencing with my hard disks.First off, I'm running CentOS as a Samba file server, on a Soltek SL-K8TPro-939 and AMD 64 3200+ (all the rage of five years ago). Here's my disk setup
I have a Centos 5.5 system with 2* 250 gig sata physical drives, sda and sdb. Each drive has a linux raid boot partition and a Linux raid LVM partition. Both pairs of partitions are set up with raid 1 mirroring. I want to add more data capacity - and I propose to add a second pair of physical drives - this time 1.5 terabyte drives presumably sdc and sdd. I assume I can just plug in the new hardware - reboot the system and set up the new partitions, raid arrays and LVMs on the live system. My first question:
1) Is there any danger - that adding these drives to arbitrary sata ports on the motherboard will cause the re-enumeration of the "sdx" series in such a way that the system will get confused about where to find the existing raid components and/or the boot or root file-systems? If anyone can point me to a tutorial on how the enumeration of the "sdx" sequence works and how the system finds the raid arrays and root file-system at boot time
2) I intend to use the majority of the new raid array as an LVM "Data Volume" to isolate "data" from "system" files for backup and maintenance purposes. Is there any merit in creating "alternate" boot partitions and "alternate" root file-systems on the new drives so that the system can be backed up there periodically? The intent here is to boot from the newer partition in the event of a corruption or other failure of the current boot or root file-system. If this is a good idea - how would the system know where to find the root file-system if the original one gets corrupted. i.e. At boot time - how does the system know what root file-system to use and where to find it?
3) If I create new LVM /raid partitions on the new drives - should the new LVM be part of the same "volgroup" - or would it be better to make it a separate "volgroup"? What are the issues to consider in making that decision?
I created a customized Lucid image and installed on my computer which has 1 hard drive (/dev/sda)When I booted up .. it gave me an error indicating "Multiple active partitions" ... and did not boot up ...
I used my live CD and run as live session to check on the hard drive, When I issued the command fdisk -l on an terminal , the out put indicated that only /dev/sda1 is bootable, and other /dev/sda* were not bootable ...
I am not sure why I got the "Multiple active partitions" message at boot up time ..
Is it possible to automate the configuration of a servers raid drives (my system has a HP Smart Array P400 controller) or does that have to be done manually? Right now, when I get a rack of new servers, I have to go through each one and use the ORCA tool to setup the logical drives. I'm hoping there is some way to automate that. And forgive the lame question, but I am assuming you have to configure the logical drives before you can install the OS?
We have a requirement to configure multiple email gateways, for mail accounts configured on linux server. the application will trigger mails (bulk mails) and we would like to configure multiple email gateway to be used.
we decided to do it this way.
In dns we would create MX records like
yourdomain.com. 3600 IN MX 20 realmailserver1.yourdomain.com. yourdomain.com. 3600 IN MX 20 realmailserver2.yourdomain.com.
where realmailserver1.yourdomain.com. and realmailserver2.yourdomain.com. will be our email gateway.
and internally on our linux server (from which mail is sent) if i specify multiple smart hosts like
So, at the moment I have a 7TB LVM with 1 group and one logical volume. In all honesty I don't back up this information. It is filled with data that I can "afford" to lose, but... would rather not. How do LVMs fail? If I lose a 1.5TB drive that is part of the LVM does that mean at most I could lose 1.5TB of data? Or can files span more than one drive? if so, would it just be one file what would span two drives? or could there be many files that span multiple drives drives? Essentially. I'm just curious, in a general, in a high level sense about LVM safety. What are the risks that are involved?
Edit: what happens if I boot up the computer with a drive missing from the lvm? Is there a first primary drive?
We have made a fresh installation on DL 580 G 5 Server. The installation Completes successfully. When we reboot the server we find an error message " Logical Drive Disable due to Possible Data Loss. and then non system disk or disk error.
Due to this we have lost all of the data. We can successfully install Windows Server 2008 or 2003 or Redhat Enterprise Linux 5 on this server with no error no issue.we can successfully install Windows Server 2008, 2003 or RedHat Enterprise on RAID 5 or RAID 6 Or RAID 1 or RAID 1+0. we dont face any issue on these windows or linux platforms.We are only facing RAID Controller Issue on CentOS 5
I have setup CentOS 5.2 with Nagios to monitor my network and have that configuration almost done. I have also setup Sendmail to forward all mail (really only Nagios notifications) out to my Exchange server using define('SMART_HOST', 'exchange.domain') in the sendmail configuration file and it seems to be working correctly.is there a way to configure Sendmail to forward all mail out through my Exchange server as it is now but send mail out to the internet itself if the exchange server is unavailable, somewhat like a failover configuration.
I have a XP/ubuntu 8.04 dual boot setup and I walked away from the PC for a minute and when I returned I had "SMART command failed error. Press f2 to resume" on-screen. I pressed f2 and it went to grub boot menu which gave error 16 and froze. I ran Ubuntu live cd which appears to freeze after selecting try without install(latest attempt appears to freeze on ubuntu logo loading up).
I ran Hiren CD miniXP but the My Computer doesn't recognize the disk nor does it appear in the disk management console. HDTune and a partition tool doesn't see the disk.I ran Hiren CD linux recovery but that loops with IO error. My latest attempt is running Ubuntu 10.04 Live cd which is appears to be loading, slowly at least.I have an external hard drive and usb stick ready to copy to. I also have my laptop. It will be greatly appreciated if someone can tell me how to get my files off the drive.
edit: just pressed esc and these lines keep appearing. udevd: worker  unexpectedly returned with status 0x0100 udevd: worker  failed while handling '/devices/i0000:00/0000:00:1f.1/host0/target0:0:0/0:0:0:0/block/sda/sda1' worker is sda2, 171 is sda3 and 172 is sda4.
I'm trying to setup sendmail to use my gamil account as a mail relay but with no success. I followed these guides: [URL]and many others.my machine is a centos 5.5 vm running under opensuse host. ( I hope that its not just a virtualbox problem..)
I ended up with this setup: /etc/mail/auth/client-info: AuthInfo:smtp.gmail.com �U:root� �I:xxxxxx� �P:xxxxxx� "M:PLAIN LOGIN" AuthInfo:smtp.gmail.com:587 �U:root� �I:xxxxxx� �P:xxxxxx� "M:PLAIN LOGIN"
I used Ubuntu before, without problems but since the 10.04 version it won't recognize my partitions. I formated my laptop and partitioned it, installed Windows 7 64bit, which I need for my work, and wanted now to install Ubuntu 10.04/10. I then used GParted to check my Harddisk and it is having troubles to recognize my partitions, too while Windows finds them. GParted is giving me an error message saying my partitions are oversized. I am still in the beginning of my Linux experiences and so I don't know what to do. I have two 250GB harddisks (how Windows recognizes them),
I upgraded to Ubuntu 11.04 from 10.10 about a week or so ago and since the upgrade when I boot into Ubuntu (I am running a dual boot Ubuntu and win7) other HDD's and partitions often do not show up anywhere on my system. For example I have an ntfs partition that I store music on so I can access it on either windows or ubuntu, as well as other partitions. When this issue occurs even my dvd drive appears not to exist. I have to reboot my machine sometimes 4 or 5 times before the drives/partitions show again. I had no issue like this before running the upgrade or using earlier versions of Ubuntu.
I was running CentOs 5.3 and did a "yum upgrade" and got the following problem: Transaction Check Error: file /usr/share/man/man1/xdelta.1.gz from install of xdelta-1.1.4-1.el5.rf.x86_64 conflicts with file from package xdelta-1.1.3-20.i386
It seems that somehow multiple entries were made for the xdelta package - how do I clean this up?
I have a new system using an Intel DG451D main board. I have been trying to get a RAID 1 mirror set working as the main drive in this system and for some reason, my SATA drives - three of them all new have had their SMART data changed to show the drives as failing and in need of replacement. Eventually the drive reports failure to the degree that the BIOS no longer recognises it. When loading the Centos os I was getting differing results because of this issue. I am not sure if this is a hardware issue even - I know that the drives were all very much OK and brand new - no good now! Just putting a feeler out to see if anyone has had a similar issue or to see if anyone knows of any possible known causes for this?
Failing any explanation, can anyone suggest a good desktop style Main Board that supports RAID well for Centos 5.4? I plan to sue this as a small server system so graphics etc are not important here.
So I'm trying to copy some media from my main hard drive to an external drive.In particular, I'm clicking folders (each containing O(15 GB) in files) and dragging them into a folder on my external HD. Fedora pops up an error message saying there was an I/O error for some of the files I'm trying to copy.So, now, some of the directories copied right, and one seems to have gone haywire. In particular if I navigate to /media/China Disk/TV/Battlestar/ and then run ll, I get the following output
Code: ls: cannot access Battlestar.Galactica.S03: Input/output error total 12
Is there a way that I can get Dolphin to mount partitions? When I try to, it gives me an error on the bottom of the window saying I don't have permission to. I also can't mount partitions in other programs like Amarok, because of the same issue.
Error Message: An error occurred while accessing 'Windows 7', the system responded: org.freedesktop.Hal.Device.PermissionDeniedByPolicy: org.freeDesktop.hal.storage.mount-fixed auth_admin_keep_always <-- (action, result)
I've been struggling with this one for a while - I have three SATA hard drives installed on my system: /dev/sda - an 80 GB disk with three partitions, one NTFS for WinXP, one ext4 for Fedora 11 x86_64, and a boot partition /dev/sdb - a 250 GB disk with one partition, ext4 /dev/sdc - a 250 GB disk with one partition, ntfs
I can mount any partition on /dev/sda without problems - everything works exactly as expected. Attempting to mount a partition from one of the other disks results in something like the following (this is for sdc1):
Code: [User@machine ~]$ sudo mount -t ntfs /dev/sdc1 /mnt/shared [sudo] password for User: ntfs-3g: Failed to access volume '/dev/sdc1': No such file or directory ntfs-3g 2009.11.14 integrated FUSE 27 - Third Generation NTFS Driver XATTRS are on, POSIX ACLS are off

I have quite a lot of testing operating systems installed. Some with their own home or boot partition. Now my places section in nautilus is an utter MESS. I was not able to find any working solution how to hide these partitions.
When I tried to install Ubuntu 9.10 or 10.04 (from CD or USB drive), and selected manual partitioning, the installer would not show all my drives.
However, when booting the life CD/USB, gparted or the Disk Utility did recognize all drives and partitions.
It turned out that one of my drives was marked as RAID partition, although I never used RAID!
Here the symptom:
When you run the installer and select "manual partitioning", the resulting list of drives and partitions is incomplete. In my example it was:
sda - sda1 sdc - sdc1
You may have multiple drives with the RAID metadata on it. In that case you need to repeat the above command for all those drives. Just make sure you don't wipe out your existing RAID, if you have one.
Reboot the system and see if it works.
P.S.: Also check your BIOS settings - do you have drives configured as RAID?
I want to re-setup a raid array on some older drives using mdadm. That involved adding a single partition on 4 of my drives (3 older, 1 brand new - a replacement drive), using mdadm to create the array, etc. However, upon restarting the box, the 3 older drives do not show up as having partitions and hence mdadm cannot immediately start the array because 'there are not enough disks to start'.For example, if I do an ls command before I restart, I will see:
Code: ls -ltr /dev/sd*1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1
I am attempting to install CentOS 5 on a Dell poweredge 6400. The drives are configure for Raid 5 with about 67 gigs of space on the server. When I select any option under Partitioning of your hard drive, it gives me an error. " No Drives found - An error has occured - no valid devices were found on which to create new file systems. Please check your hardware for the cause of this problem."
I've been through a lot of the posts already, but nothing seems to solve my problem. I have Ubuntu 9.10 and Windows 7 dual installed (Windows was installed first). Everything has been working fine until a few weeks ago when I accidentally left a USB drive plugged in when I restarted my computer from Windows.
Ever since then, whenever I have restarted my computer from Windows grub2 has failed (it does not fail when I restart from Ubuntu). I get a varying message like Grub loading. The symbol ' ' not found. Aborted. Press any key..where the part between the single quotes is usually different each time. When this happens I have to reinstall Grub2 from a live disk, which is becoming a bit of a pain.
I've been reading around, but I don't really have a great understanding yet of how hard drives and partitions work in general, and so I haven't been able to work out what the source of this problem is.
I have 2 drives formatted NTFS, which I'm mounting with /etc/fstab to ~/Movies/ and ~/Music/ and an EXT4 partition on my primary drive for games, mounted to ~/Roms/ and I would like for these drives to NOT show up in the side panel of nautilus.
I've been doing some looking around, and what I've found so far is that supposedly if you mount a partition/drive somewhere besides /media/ nautilus will ignore it. I'm finding this not to be the case, and it's driving me bonkers. here's my fstab:
Code: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5).
Its from a Synology Box with 3 disks, which one is damaged. But this disk wasnt in use.Take a look on the raid-size of 493 GB - and the both available disks with 250GB..) On the others there were a linear raid. during this damaged disk the synology-device tells me, that the volume was crashed.But it look like, that this disk was not mounted into this volume.Quote:

i'm tying to dual boot Vista64 (already installed) and Fedora 10 x86_64. I am running a Dell XPS 410 running 2 sata hard drives raid 0 (ICH8DH). I started the process by shrinking my C drive on disk0 leaving 64.45GB of unallocated space. Next I rebooted into Fedora install DVD and when i get to blue graphical install screen i get message asking if my drive is GPT and if it is it may be corrupted. I click NO, and it comes up with a message telling me i have to initialize my drive if i want to use it ( have to click NO twice) and if i do it i will lose all my data.
i can click no and keep proceding through the install until i get to the partition setup screen. No hard drives or partitions are shown. I've tried googling the problem and get bits of pieces of information scattered in different parts but nothing conclusive to my problem i think. As far as my background of knowledge goes, I'm new to the linux community but give me a thorough guide and i'll do fine (i hope). I've been using fedora on a separate laptop for 2 days now .
My computer has 2 40GB hard drives (yes, it's really old). One of these hard drives has Ubuntu installed on it, and I would like to use the second hard drive as a data storage device that is usable by anyone who just wants a random place to drop random stuff. How do I do this?
i am new in Linux. i have two drives one IDE and other SATA in my computer.i want to keep windows XP , WIndows 2003 server on one drive and two flavours of linux on the other drive, let say oopen suse and redhat.please help me how i install these sofwares to make multi boot the machine.
