Ubuntu Servers :: Complete Noob - 10.04.LTS "Advanced Format Disk" Self-FUD?
Mar 2, 2011
Old Commodore Vic 20/DOS/Wintel guy here who wants to make a first foray ever into Linux by building a home server with 10.04. I've found so much seemingly conflicting information that I'm lost at sea about hard drives.
I bought the Official Ubuntu Server Book, The (2nd Edition), and started reading it, learning about file system and planning a different /home partition, potential software raid, and such pre-install considerations.
The cheap hardware I had considered is: HP ProLiant ML110 G6 Intel X3440 2.53GHz 2GB Memory w/ DVD ROM & 250GB HDD 3 x SAMSUNG Spinpoint F4 HD204UI 2TB 5400 RPM 32MB Cache SATA 3.0Gb/s 3.5" 6 more GB RAM for total of 8 The Samsung drives are Advanced Format. I read some reviews about OS partition alignment issues, and the past 2 days I've been down numerous rabbit holes of search on this forum and google in general about whether this will be a problem in 10.04. I'm wallowing in my own search-overload-induced fear, uncertainty, doubt, and paranoia now.
The release notes lead me to believe that "no brainer" support for these drives is now baked in to 10.04 ? That if I just follow prompts, the new install will partition and format drives properly aligned?

Can anyone tell me if F15 is aware of the new Advanced Format Hard disks. The new dell laptop has one of these drives in it. The reason for the question is the disk is a 250Gb but only seems to have 230ish available which does seem a lot to loose? The dell website only talks about Windows and not linux. Below is from their site:
"In an effort to support higher capacity hard drives, the Hard Disk Drive (HDD) industry is moving towards Advanced Format (AF) HDDs with 4KB sectors to address the current limitations with the 512-byte sector HDDs. The transition to 4KB sector HDDs will allow storage devices to more easily adopt larger capacities in both the notebook and desktop space. While hard drives will transition to 4KB sectors and to maintain backwards compatibility, current Advanced Format 4KB HDDs, also known as 512e HDDs, will emulate 512-byte SATA communications to hosts and will operate at 4KB."

So I finally bought an advanced format drive, the 2 TB Samsung f4. I will be using it on my slackware box, running slackware 12.2 with kernel 2.6.27-7. I intend to format the drive by hand with fdisk and start the first partition on sector 2048, or perhaps boot a livecd and format it with a newer version of fdisk or parted that will natively partition this drive correctly. My real question is, do I have to do anything special to add this drive to an existing LVM volume group? I'm thinking no, since LVM basically just breaks all your data into 4 MB chunks and spreads them across the pool of partitions you've defined, but I've found many conflicting opinions from searching google. To simplify things, I'm not using RAID of any sort, neither hardware nor mdraid.

My System Intel Core Duo E5300 Mobo - Gigabyte G31M-ES2L 1GB DDR2 800MHz RAM 4 x WD20EARS HDD I have been trying to install Fedora or Ubuntu for over a week. I thought it would take an hour and i would be away. I have been trying to install using the mdadm Software RAID feature. Everytime it takes about a day to format the drives and then i get an installation error. The drives state they are ready to use as is on any operating system other then WinXP, but this does not appear to be the case.
I am very new to Fedora... I have been doing some reading.[URL].. That information has been promising. I have been able to get into Fdisk off the live CD but i can't figure out how or if it is possible to do what i want it to.
Has anyone had any luck getting these drives to function correctly in a software RAID? I have had good luck with WD drives in the past and just assumed these drives would do what i wanted to but alas i have been proven wrong.
The partitions i wanted was...
- A 2GB swap parition
- A 10 GB RAID 1 partition for Fedora
- The remaining space as a Raid 5 for files.
Am i just banging my head against a wall here, or is this possible.

Upon trying to open a .wmv file, the system says it wants the above - which I suspect is not provided under the same name and is proprietary. Can anyone suggest the name of a plugin in the repository which would suffice? The file came as an attachment to an email file.

I have 2 WD20EARS hard drives on the way (2 TB green WD disks with 4k sectors) and I'll be installing Centos 5.5 in RAID1 on them (2 partitions, one 16 GB / at the beginning and the rest in its own partition). I read the following thread: [URL]
and it seems that I might be having problems with the 4k sectors (Advanced Drive Format in WD lingo). I'm confused as to what exactly to do. I was thinking of downloading Fedora 14 Live CD and partitioning there and then switching to Centos 5.5 to install. Will that work? Seems I want the md 0.9 metadata because it doesn't have the space limit for me (2 TB) and it's stored at the end of the partition so it avoids alignment issues. Will I be able to make that happen with Fedora 14?

How do I connect to the MySQL server using phpmyadmin?It's asking me for a username and password and I was not asked for a root password when I installed MySQL (unlike in Windows).I tried no password, I tried root as a password, I tried$ mysqladmin -u root -p blahEnter password: mysqladmin: connect to server at 'localhost' failederror: 'Access denied for user 'root'@'localhost' (using password: YES)'Nothing I've tried is working obviously.Why does this have to be so stupid? Why couldn't MySQL ask me what password I want to use?

I currently have Ubuntu installed on my laptop.I have it set up the way I like it. However, I want Windows on here too...the thing is, I dont want to have to format if possible, I know that you need to install windows before Ubuntu. I have ubuntu all set up how I Like it and it would be a shame to have to wipe it.Is there any way at all I can install windows along side it without having to do a complete format?

I am getting a new 4kb sector HDD for my laptop, WD scorpio black 750gb, I would like to image existing partitions on 512bytes sector HDD and move them to the new 4kb sector HDD, what's the best way to do this.
present config is as follows:
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders, total 156301488 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
[Code].....
I am planning to keep the same three partitions as the primary partitions on the new drive and add few more logical partitions. I would have liked to move to GPT but since I need Win 7, I am stuck with MBR partiotion table.
Now, I understand how to partition an Advanced format disk, what I want to know is how to move the existing partitions on the 80 Gb disk to the new disk?
I use Clonezilla to copy partitions but it is not compatible unless both the target and the source disks are already using 4096 sector size.
I can use Acronis True Image WD Edition to clone Win 7 but how do I clone Ubuntu?
Also my Laptop's chipset is limited to SATA 1.5, will it cause any issues, I know the bandwidth is not an issue.

Is the term a 'simple SMTP relay' a contradiction in terms?!I have an elderly Dell server on which I have just made a fresh install of 10.04 LTS server. I had 8.04 running on it for a long time, but I haven't tried an SMTP server before. It is a headless server with CLI (no GUI) and the latest version of Webmin installed.I have a basic LAMP server installed for a few websites using PHPbb and Joomla, and also I run a Mediatomb server for our household. When I installed I also chose to install mail services, but these remain masked behind NAT at the moment
I now want to set up an SMTP relay server so when I am working away and using different wifi points or my notoriously unreliable 3G dongle I can always send emails through the home server (from my iPhone and my laptop) rather than having to look up the SMTP server for each ISP of the place where I am working.
What I want is an authenticated server which takes my email and redirects it to my home ISP's SMTP server. I need only 3 authenticated users to have access (myself, my wife and my son). I don't need (or want) any incoming mail services at all.
Useful modules installed are: Dovecot, Postfix, Procmail mail filter, PAM - but how do I set them up?
Is there any simple setup that I could do, preferably through Webmin, but I can handle CLI if necessary?
I have looked at the Ubuntu help pages, but it looks so complicated to set up something that seems like it should be so simple to me.

the recent versions of fdisk on Fedora 13 and Ubuntu 10.04 are supposed automatically to solve these things around 4k sector aligment thing if one starts fdisk with -u and -c flags. But I'm getting confused as the heads / sectors informations always differ every time I create a partition.I have WD Green 1.5TB disk. I want 2 partitions. sdb1 with 1.3TB and sdb2 with the remaining space. Here's how it looks like. When I create the first partition (1.3TB one), I get following listin with fdisk:
Code:
# fdisk -lu /dev/sdb
Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes
78 heads, 37 sectors/track, 1015342 cylinders, total 2930277168 sectors
Units = sectors of 1 * 512 = 512 bytes

I have a Raid5 software partitioned using LVM (at centos 5.2 installation). Actually the raid is composed by 3 320Gb HDD. I would like to replace them with 3 2T hdd, but I'm worried about the alignment issues of the upgrade. I know it is easy to align the raid partition URL But what will happen to the LVM partition? Reformat and install everything is not an option

I'm trying to create a user account for my children in Ubuntu 10.04
When creating their account, I have turned off the 'Connect to ethernet and wireless' option of the Advanced Settings.
However, when I log into their accounts, they still have full access to the internet through both the wireless and ethernet connections. Is this option for some other purpose?
Is there an alternate way to limit internet access for childrens' accounts in Ubuntu? (I'm used to MS Family Safety as a filter for internet access - is there an eqivalent for Ubuntu?)

Last time I installed Ubuntu in a dualboot configuration with Win7 on one of my machines, my entire boot sector and Windows install got corrupted, resulting in a complete loss of all my data and requiring a fresh install of Windows.
I looked into this a bit after the fact, and it seemed to me it was due to conflicting hard disk geometry between Linux and Windows.
My question is, how likely is this to happen with Fedora? Is this because of Ubuntu? A bad install? Is there someway I can avoid this from happening when I install Fedora if it will happen?

Thought I'd post it here because it's more server related than desktop... I have a script that does:
[Code]....
This is used to sync my local development snapshot with the live web server. There has to be a more compact way of doing this? Can I combine some of the rsyncs? Can I make the rsync set or keep the user and group affiliations? Can I exclude .* yet include .htaccess?

Just curious if it is possible to schedule a complete system shutdown and start up?
My box with ubuntu server on it is only used as an ssh/proxy server, so I would like save on energy costs and add a layer of security by completely shutting it down during the hours I do not use it.

I have an Ubuntu 9.10/64 Server configured with LVM in a 1Tb sata disk in my home server. For a simple server, LVM adds complexity if you need to recover your system, so I decided to migrate from LVM to normal partitions. I have another 1Tb disk to copy my system disk. In the backup disk, i have created same size partitions and trasfered files from /boot and root volumes with rsync, presenving perms etc... and excluding /dev /proc /sys etc... I have then modified /etc/fstab to mount new UUID's and reinstaled grub via live CD and chroot.
At this point, when I replace my system disk with backup one, the boot process start as usual, but when it starts loading services the boot process does not continue. The system is not "frozen". If I press intro, there is a line feed on screen. If I mount the backup disk in another system, there is nothing writed to /var/log/syslog or dmesg files during the boot process. I can change terminal with <alt>F2 but there is no login. In console, with backup disk I get:
Code:
....type 1505 audit.... operation="profile_load".....
Done.
fsck from util-linux-ng 2.16
/dev/sda1: clean ......
fsck from util-linux-ng 2.16

I want to format an USB disk with ext3. If I do this with gparted, it will be formatted, but I cannot write to it. Reading is no problen, at least it shows the lost+found folder. I guess its a problem with access rights. It would be sufficient if user "papa" would have access on one ubuntu karmic machine. But I cannot solve this graphically. The purpose of the operation is to be able to copy my /home directory onto the USB disk as a backup, before I upgrade to the current version of Ubuntu. FAT32 is no option as some files are too long.

I got a 40GB seagate HDD which has got through some unsuccessful windows and linux installations and now all the partition tables are corrupted... I tried to format with System>Administration>DiskUtility but it gives this error when I'm do: Error creating partition table: helper exited with exit code 1: Error calling fsync(2) on /dev/sdb: Input/output error gParted was not even useful since it didn't not even detected the drive...
Isn't there any simple way to format the crap from the Ubuntu 10.04 Live CD? I believe that on windows, there wouldn't be that problem since the "format c:" crap just format the drive without asking questions. All I want to do is to format the drive so I can create partitions later. Also, I have only access to the live CD and I don't have any Diskette drive installed.. I believe we now live in a world where this crap isn't needed to fix a computer.

I have an SiI hardware SATA RAID card, with two 500GB disks in mirrored RAID configuration. When I first plugged them in and set it up, things seemed to work ok, but on boot the raid controller told me that the RAID needed rebuilding, and it would happen automatically after POST. So I didn't worry about it, and the drive mounted fine, and it's been that way for years. I just went in and manually on-line rebuilt the RAID in the controller's BIOS, and now when I boot into Ubuntu, both disks show up in fdisk, but neither show up in /dev/disk/by-uuid. Am I missing something?

Opensuse 11.4 seems to be creating problems with booting from USB devices. (I have read in a couple places that people are having similar problems.)
Every time I try to boot from a different live USB image, I see a GRUB screen flash and the hard disk starts to boot up. The only live image I have had success with booting was another OpenSuse 11.4, then I got the options to install or run live. I was thinking of just wiping the hard disk and seeing if that made a difference. Can I get into the grub limited command line, can i format from here? Is some other way of installing over the WAN from inside the Suse OS?
