Fedora Installation :: Software RAID With Advanced Format WD-EARS Drives?
Dec 31, 2010
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.

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."

Is there a thread on the new Advanced Format standard? I'm reading that it's pointed at W7/Mac and I'm thinking Linux newbies (like me) should know in advance, before buying hard drives, what the state of OpenSuSE/kernel/drivers is. I never used to pay attention to hard drive numbers.

I have been battering with FC10 and software RAID for a while now, and hopefully I will have a full working system soon. Basically, I tried using the F10 live CD to setup Software RAID 1 between 1 hard drives for redundancy (I know its not hardware raid but budget is tight) with the following table;
[Code]....
I set these up by using the RAID button on the partition section of the install except swap, which I set-up using the New partition button, created 1 swap partition on each hard drive that didn't take part in RAID. Almost every time I tried to do this install, it halted due to an error with one of the raid partitions and exited the installer. I actually managed it once, in about...ooo 10-15 times of trying but I broke it. After getting very frustrated I decided to build it using just 3 partitions
[Code]....
I left the rest un-touched. This worked fine after completing the install and setting up grub, reboot in to the install. I then installed gparted and cut the drive up further to finish my table on both hard drives. I then used mdadm --create...etc to create my RAID partitions. So I now have
[Code]....

Fedora is having trouble identifying a raid partition, it sees them as separate drives. I got drivers from dell, but during a Fedora dvd install, it mentions nothing about a place to install extra drivers.
When it says it must "initialize" the drives, Fedora then breaks the dell bios raid. How to either install the dell drivers or make Fedora see the raid partition as one?

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.

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?

I was recently given two hard drives that were used as a raid (maybe fakeraid) pair in a windows XP system. My plan was to split them up and install one as a second HD in my desktop, and load 9.10 x64 on it, and use the other for mythbuntu 9.10. As has been noted elsewhere, the drives aren't recognized by the 9.10 installer, but removing dmraid gets around this, and installation of both ubuntu and mythbuntu went fine. On both systems after installation however, the systems broke during update, giving an "read-only file system" error and no longer booting.
Running fsck from the live cd gives the error:
fsck: fsck.isw_raid_member: not found
fsck: Error 2 while executing fsck.isw_raid_member for /dev/sdb
and running fsck from 9.04 installed on the other hard drive gives an error like:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
In both cases I setup the drives with the ext4 filesystem. There's probably more that I'm forgetting... it seems likely to me that this problem is due to some lingering issue with the RAID setup they were in. I doubt its a hardware issue since I get the same problem with the different drives in different boxes.

I have recently installed a Asus M4A77TD Pro system board which supports raid.
I have 2 x 320gb sata drives I would like to setup raid-1 on. so far i have configured the bios to raid-1 for drives, but when installing Ubuntu 10.04 from the cd it detects the raid configuration but fails to format.
When I re-set all bios settings to standard sata drives ubuntu installs and works as normal but i have just 2 x drives without any raid options. I had this working in my previous setup but thats because i had the o/s on a sepreate drive from the raid and was able to do this within Ubuntu.

My two 400G drives which have been added to a single 800G array (per fastbuild bios utility) still show up as two 400G drives in fdisk. Why is that?

I'm breaking into the OS drive side with RAID-1 now. I have my server set up with a pair of 80 GB drives, mirrored (RAID-1) and have been testing the fail-over and rebuild process. Works great physically failing out either drive. Great! My next quest is setting up a backup procedure for the OS drives, and I want to know how others are doing this.
Here's what I was thinking, and I'd love some feedback: Fail one of the disks out of the RAID-1, then image it to a file, saved on an external disk, using the dd command (if memory serves, it would be something like "sudo dd if=/dev/sda of=backupfilename.img") Then, re-add the failed disk back into the array. In the event I needed to roll back to one of those snapshots, I would just use the "dd" command to dump the image back on to an appropriate hard disk, boot to it, and rebuild the RAID-1 from that.
Does that sound like a good practice, or is there a better way? A couple notes: I do not have the luxury of a stack of extra disks, so I cannot just do the standard mirror breaks and keep the disks on-hand, and using something like a tape drive is also not an option.

I am trying to recover some data on some drives that are in the same LVM. When I upgraded the motherboard, I had complications getting the drives to all load under the LVM, and in the process I made the mistake of formatting one of the drives. The problem now is that the UUID changed on the drive so when I try to mount the LVM it can't find device with a certain UUID. When I try to set the UUID back to the old one it says 'Invalid UUID format'.
I can set it to a UUID generated through 'uuidgen', si I then noticed that the format of that UUID is different than the old one which I'm trying to set it to. Why is that? Is there a way I can get it to change to the old one in the different format?
The old format: yQtrVB-5jCk-vF10-05c2-AcDL-GNn1-ivdxxh
The new format: d5224587-a6cd-4a66-a12b-d7b75eec5871

I have a RAID 1 that is mounted and working. But for some reason I can also see the individual drives under gnome Devices on gnome-shell. Is there a way to hide them from gnome or linux in general. (So only the raid 1 can be seen)

how to migrate my whole server to larger hard drives (i.e. I'd like to replace my four 1TB's with four 2TB's, for a new total of 4TB instead of 2TB)... I'll post the output from everything (relevant) that I can think of in code tags below.
I'd like to end up with much larger /home and /public partitions. When I first set up raid and then LVM it seemed like it wouldn't be too hard once this day arrived, but I've had little luck finding help online for upgrades and resizing versus simply rebuilding from a failure. Specifically, I figure I have to mirror the data over to the new drives one at a time, but I can't figure out how to build the raid partitions on the new disks in order to have more space (yet mirror with the old drive that has a smaller partition)... don't the raid partitions have to be the same size to mirror?
Ubuntu Server (karmic) 2.6.31-22-server #65-Ubuntu SMP; fully updated

cat /proc/mdstat

So windows wouldn't recognize my drives as a raid setup, so I disabled it and switched to IDE, now Ubuntu 9.10 installation will only recognize my drives as RAID. I have and ASUS M3A32-MVP Deluxe Series motherboard, it has 4 sata connectors and 2 marvel controlled sata connectors. In the 4 sata connectors I have my 2 wd 500gb hds, my dvd burner, and my external usb, esata slots. In the marvel controlled sata connector I have a wd 160gb hd. Originally when I built the computer I wanted a raid setup with the 2 500 gb hds.
But windows wouldn't recognize the raid set-up and wouldn't boot properly. So I said screw it and removed the raid and set all the drives to IDE. Then, when I tried to install Ubuntu 9.04 it would only recognize my 2 500 gb hds as raid. Gparted recognizes the drives as both raid and IDE. Eventually, after a day or two of praying and messing around the installer recognized both drives as raid and IDE. A couple months later here I am trying to install Ultimate Edition 1.4.

I am currently trying to configure a set of hard drives as a RAID configuration. My system is running with Red Hat Enterprise Linux Client release 5.1 as the base OS. I am booting from CD. I am trying to image a set of drives that have not been imaged before. When the GUI dialog window for disk setup is displayed, it shows a default disk layout including a LVM slice. In the disk layout is a /boot partition already. It is not what I would like so I edit it to be the size for my system and make it the primary partition. I also select it to be a software RAID. I then add three more partitions for my drive 'A' all of type software RAID and NOT primary partitions.
At this point my drives have the correct number of partitions except for showing the LVM slice. I select 'RAID' again, followed by selecting 'Clone a drive to create a RAID device ...' followed by 'OK'. I then get a dialog to select the source and target. i select my drive 'A' to be the source and 'B' to be the target followed by 'OK'. An error dialog is received stating that all the partitions are not of type software RAID. The disk partitions are all type software RAID except the extended LVM slice. I can not get past this point and I am following a procedure written some time ago by a person that is not available.

I just installed Debian 5.0.4 successfully. I want to use the PC as a File Server with two Drives configured as a RAID 1 device. Everything with the RAID device works fine, the only question I have belogs to the GRUB 0.97 Booloader. I would like to be able to boot my Server even if one of the disks fail or the filesystem containing the OS becomes corrupt, so I configured only the data partitions to be a RAID 1 device, so on the second disk should be a copy of the last stable installation, similar to this guide:[URL]...

I recently installed Fedora 12 for use with Amahi HDA. Before installing on the Hard drive I used the LIVE CD to test it out. While using the LIVE CD I could see all my HDD's. My file system, my 2nd Hard Drive, and my Raid 0 Configuration. (2 250GB drives) and could browse all my files on those drives.
After installing the full version on my hard drive, my RAID drives are showing up as seperate drives. I have a Asus P4P800 board using hte SATA raid. I know its FAKERaid and not a true hardware raid.
My goal is to restore the Raid in Fedora and make those drives active. However, i dont want to lose any of the data on those drives. To make sure I wasn't an idiot, i rebooted withthe LIVE CD again and verified that I could see the Raid Array.

I am purchasing a Western Digital WD10EARS 1TB hard disk for use with Fedora 11. My questions is will I get good performance or do I need some tweaking?
This drive has the new Advanced Format with 4k physical sectors. Some people have had performance problems with these drives. I want to make sure Fedora 11 can format the drive corectlly.

Ok so was looking through a guide and stumbled on this: ppc --> 32-bit, compatible with all Macintosh computers (excluding Intel Macs) and the PlayStation 3. Does this mean that if I have some old Macs (G3s) to be precise I could put Fedora on it? Does this involve a whole lot of hacking or not?

I'm looking to set up a server with attached mass storage device and tape autoloader to run linux. It's set up under Windows at the moment. Goal is to have users, connecting from individual workstations and laptops, backup their data to the linux server. On their personal machine, some users run linux, some MacOS, some Windows. I plan to set up the 5 500 GB drives as RAID5. I understand that if setting up as software raid the format is "physical volume for RAID". Under this setup, will Windows users be able to read/write and function as expected? I can't assume only linux user access.

I just went out and bought stuff to build a new computer, and among the parts was a Gigabyte ga-890fxa-ud5 motherboard ([URL]). The board has 3 (well, 4, but we'll stick to the 3) main sata interfaces, with 2 slots per interface, allowing 6 sata drives. In slot_0 i put my blu-ray drive, in slot_1 i put my drive that will host the OS and its partitions, and that is in the sata connector pair on the left. The middle sata connector pair (slot_2 and slot_3) i have 2 2tb drives, and in the sata connector pair on the right (slot_4 and slot_5) i have 2 1.5tb drives.

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?

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.

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

How many partitions should I create and where should I mount them? (I should mention that Ubuntu will be the only OS on this array.)
