Hardware :: 3 SATA HDs Installed - Drive 2 Shows No Partitions In F12

May 2, 2010

I have three sata drives installed in my machine. 1 is my boot drive, contains a windows install, and a linux install. All is well here. Drives 2 and 3 are simple fat32 volumes, I store my data on drive 2, and periodically sync it to drive 3. I do this simply for backup reasons. It was only recently that I setup this scheme. Previously I had all 3 drives in a fakeraid setup. Raid 5. I broke the array to set things up as I've described. All is well in windows, all 3 drives work as expected. However, in linux (fedora 12), drive 2 shows no partitions! If I do an fdisk -l, it shows sdb1, but if I attempt to mount it, I'm told that /dev/sdb1 does not exist, and in fact, /dev/sdb1 does NOT exist. sdc1 however, does exist, and is mountable.

A few things I've noticed with seem relevant.
Gnome reports a raid5 drive, which if I try to interact with it, fails.
Gparted shows sdb as a standard drive.
Dmesg shows the following, I've grepped out sdb and sdc for comparison, as they should be identical.

Code:
[root@azure ~]# dmesg | egrep 'sdb|sdc'
sd 2:0:0:0: [sdb] 1250263728 512-byte logical blocks: (640 GB/596 GiB)
sd 2:0:0:0: [sdb] Write Protect is off
sd 2:0:0:0: [sdb] Mode Sense: 00 3a 00 00
sd 2:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA ....

Seems to me that the lines:
Code:
raid5: device sdb operational as raid disk 1
disk 1, o:1, dev:sdb
have something to do with it.

I did play around with mdraid while my array was apart, but I cant seem to find any method of testing sdb to see if something is somehow still configured on that drive. I've re-written the partition table, and even performed a low-level format on the drive, nothing seems to restore its function in linux.

Ubuntu Installation :: Multi-Booting - CD Drive - Also SATA - No Longer Shows Up

Apr 16, 2010

I decided to install the Ubuntu Netbook remix (9.10, I believe) on this extra IDE hard drive I had (my other three hard drives are SATA.) My primary hard drive contains a Windows XP, my second contains Windows 7, and my third SATA drive is just NTFS-formatted storage. I went through the installer and choose to format and install on my 40GB IDE hard drive, which it did. Then it finished and rebooted. It apparently decided to install the GRUB bootloader onto the primary hard drive (not the one it was installed on,) which was not my intention. The bootloader froze the boot of my computer and wouldn't work. (Stuck at loading GRUB.) I couldn't even get to the BIOS. So I pulled the plug on the primary hard drive and tried to boot again. I could get into Windows 7 just fine, but that was it. The problem, though, is that the CD drive (also SATA) no longer shows up in My Computer. Also, after changing the boot order and replugging in the former primary hard drive, it wouldn't show up, either. Nor would the IDE one (though I'm pretty sure that's because Windows doesn't understand the EXT (or whatever Ubuntu uses) file system.

Does anyone know why this occurred and how to get those drives to show up in Windows again? I don't really care to get the netbook remix working here, since this isn't even a laptop, it was just an experiment. Also, I'd love to know how to remove GRUB from my primary hard disk so that I can boot from it again.

CentOS 5 Hardware :: SATA Disc SMART Data Shows New Drive Faulty Centos5.4?

Nov 26, 2009

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.

General :: One Of My LVM Partitions Is Not Mounted/does Not Shows Up

May 26, 2011

Created partitions, some of them LVM, in a server, say A. Did the same for another server, B, but created one more LVM partition.

Installed RHEL in A, and some other applications. Made dump files for each partition of A and restored all of them them in B. No error in that process, except B wouldn't boot. Did chroot /mnt/sysimage and grub-install /dev/sda--still no good. B came to a halt with GRUB> dispalyed. <tried many things many times.. searching Googles..but w/o luck) Gave up, and restored the bootloader part using OS CD -- I say restored because now B boots ok and I can see application that I had installed in A. So far so good.

Problem: that extra LVM partition is missing! I did not knowingly overwrite it, so where did it go? Somebody is keeping it from being displayed!

Is it the grub.conf that tells the OS what to mount and what not to? If yes, problem is , grub.conf is missing in B. In A, it is in /boot/grub/. df -kh shows other partions (some of them LVM) just fine.. what is going on?

I tracked a file called menu.lst in a strange place, in /usr/share/doc/grub-0.97.. but I didn't see any entry that loads partitions.

Debian Configuration :: Lsblk Shows Non-existent Md Partitions After Reboot

Jan 14, 2016

I'm getting weird behaviour while setting up an mdadm RAID1 array on debian 8.2.

After I set-up the array, lsblk shows:

Code: Select allsimon@debian-server:~$ lsblk
NAME                          MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda                             8:0    0 931.5G  0 disk
`-sda1                          8:1    0 931.5G  0 part
  `-md0                         9:0    0 931.4G  0 raid1
sdb                             8:16   0 931.5G  0 disk

[Code] ....

After a reboot, lsblk shows:

Code: Select allsimon@debian-server:~$ lsblk
NAME                          MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda                             8:0    0 931.5G  0 disk
`-sda1                          8:1    0 931.5G  0 part
  `-md0                         9:0    0 931.4G  0 raid1
    |-md0p1                   259:0    0 811.6G  0 md

[Code] ...

I don't know where the md0p1 and md0p2 partitions are coming from. My /etc/fstab and /etc/mdadm/mdadm.conf both have nothing about this in them.

parted shows one partition on md0:

Code: Select allsimon@debian-server:~$ sudo parted /dev/md0 print
Model: Linux Software RAID Array (md)
Disk /dev/md0: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: loop
Disk Flags:
Number  Start  End     Size    File system  Flags
 1      0.00B  1000GB  1000GB  ntfs

Where the md0p1 and md0p2 partitions are coming from?

I'm setting up the array by doing as follows:

Delete existing device (I've done this a few times):

Code: Select allsudo mdadm --stop /dev/md0
sudo mdadm --remove /dev/md0

Zero drives:

Code: Select allsudo dd if=/dev/zero of=/dev/sda bs=1M count=1024
sudo dd if=/dev/zero of=/dev/sdb bs=1M count=1024

Create partition tables:

Code: Select allsudo parted /dev/sda mklabel gpt
sudo parted /dev/sdb mklabel gpt

Create full-disk partitions:
Code: Select allsudo parted -a optimal /dev/sda mkpart primary '0%' '100%'
sudo parted -a optimal /dev/sdb mkpart primary '0%' '100%'

Set raid flag on partitions:

Code: Select allsudo parted /dev/sda set 1 raid on
sudo parted /dev/sdb set 1 raid on

Create RAID array:

Code: Select allsudo mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sd[ab]1

Add filesystem (I'm using NTFS, but the problem also happens with ext4)

Code: Select allsudo mkfs.ntfs -f /dev/md0

Fedora Installation :: Sata 1 Was NOT Installed With Grub?

Feb 15, 2010

Prefactory note - I've also posted this question on the Ubuntu forum, but so far no solutions have been provided.

My system has several hard drives. The important ones are these:

Sata 1 - Fedora 12
Sata 3 - Windows 7
Slave 1 - Storage

Sata 1 was NOT installed with grub. When I switch OSs, I do it by rebooting and choosing the other drive as primary.

I downloaded an ISO of Ubuntu 9.10 (64 bit) and burned the DVD of it. I backed up Slave 1 and then booted off the Ubuntu DVD. I clicked on "Install Ubuntu", selected Slave 1, and installed onto it.

Subsequently I rebooted the machine, going into the BIOS to boot off Sata 1, so I could get my Fedora Firefox settings to replicate them under Ubuntu.

Instead of Fedora 12 booting, Grub 1.97 came up. It had 5 choices, Ubuntu, Ubuntu Repair, Memtest, some other Memtest, and Windows 7.

Subsequently I tried cracking the box and physically disconnecting Slave 1. When I rebooted Sata 1, it crashed to a grub command line. Apparently when Ubuntu installed, it infected Sata 1 with grub, even though it installed the rest of Ubuntu on Slave 1.

I really, really, REALLY need to get access to the Fedora 12 drive. It's got my work on it.

how I can get grub out of Sata 1 and regain access, or maybe reconfigure it so it recognizes the existence of Sata 1? Personally, I don't want it there; that's why I never installed it in the first place.

Ubuntu :: SATA II / Error "ata4: Limiting SATA Link Speed To 1.5 Gbps" - Allowing The SSD To Run At SATA II Speeds?

May 1, 2011

I keep getting this error in my log viewer every 2 seconds: Code: ata4: limiting SATA link speed to 1.5 Gbps I have a dual boot SSD and I have run many SMART tests in windows and linux, (using smartmon tools and the disk utility) and the reports are all 100% healthy..... My research shows that this error represents one of the following:

1. Problem with SATA controller
2. Changing BIOS to allow SATA
3. Changing SATA mode to PATA or AHCI
4. Replacing the SATA cable
5. Allowing the SSD to run at SATA II speeds, i.e. 3 Gbps

- Does anyone know how to try number 5, i.e. allowing the SSD to run at SATA II speeds? I am lost here and this problem has caused my machine to crash twice when watching a movie in linux/ ubuntu. (It is worth noting that the crashes have only occurred in linux and I have never had an issue in windows, so it does seem to be a linux setting somewhere, hence why I think it is a "allowing SATA II to run at correct speeds issue")

Ubuntu :: My Lucid System Will Only Boot With 2 Sata Drives Installed?

Feb 14, 2011

My system won't boot unless I have 2 sata drives. It doesn't matter what's on the second one. It even boots if the second "disk" is a powered sata to IDE adapter attached to an unpowered IDE drive.If I don't have the second drive I get this when I try to boot:

Alert! /dev/disk/by-uuid/ ...<your UUID>.... does not exist,I don't see anything that seems odd to me in my /etc/fstab file.

# /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).

Debian :: Dpkg Shows Installed Pkg Is Uninstalled?

Aug 8, 2010

I have downloaded a Non-free Deb pkg, when I tried to install it using "# dpkg -i pkgname", it appeared to install as expected. The pkg exists, I found the new directory and the executable file, but if I try to run it I get kicked out of my session, and back to GDM.

When I run "# dpkg -l pkgname", immediately after the install, I get this: "un pkgname <none> (no description available)"

Since it is not installed I can not remove it, or reconfigure it.

I run Debian Testing with Openbox as my window manager.

I have tried installing grub in MBR and root changed every setting I can find and even downloaded a fresh ISO. As a last resort I changed the machines BOIS settings from SATA to emulate ide, booted as expected but a bit slow.

11.2 and 11.3 worked on this machine with no problems. Am i missing something? I also tried an Ubuntu install and this worked fine!

Ubuntu Installation :: Using Grub On IDE Drive And SATA

Aug 1, 2010

I have tried to install ubuntu onto my computer using the live CD. It installed fine, and it put grub on sda (which linux sees as my SATA drive). Windows is installed on the ide drive which linux see's as the sdb drive. It was a successful install and in theory it should work, except it find the windows install first so it boots into windows without using grub. I think that linux assigns the drives using the sata first and the ide second, but windows does the opposite and the ide drive is first and the sata is second.

Is it possible to install grub onto the ide drive and get it to dual boot linux or is it possible to use the windows bootloader to recognize the linux install and chainload grub? I am thinking that if I use grub on the ide drive it will throw an error like what happened during my wubi install and it is unable to find the kernel because it is looking for it on sda, but from a windows install it is sdb. I have tried to get the computer to boot from the sata drive, but the mobo is a bit old and I do not think it is supported.

Ubuntu :: Executable Bit And Separate SATA Drive

Jan 12, 2011

I'm having a bit of a problem enabling any sort of permissions for my 1TB SATA HDD on /dev/sda1. Using Nautilus and wine, I'm trying to play games already pre-installed on my Windows 7 partition. When ever I right-click>permissions>Enable execution, it reverses the changes. I don't know if this is relevant, but id rather not copy anything on to my /dev/sdb2/ partition because its about 1/10th the size of sda1 (142GB free to be exact). Is their any way to make a permanent change? I don't really mind if it's a solution in the terminal... So long as it doesn't mess up my ability to boot Windows 7.

Ubuntu Installation :: Boot From Pen Drive Then To Sata?

Feb 28, 2011

I have a HP PC that I have installed a PCI SATA controller in. The PC doesn't support booting from the card.... So here is what I would like to do. (btw..I'm a seasoned noob on Linux.) I would like to be able to boot ubuntu 10.10 from a usb pin drive 2Gb to a point where the kernal can recognize the SATA drive then start the OS from the SATA HDD.

I can see and access the drive if I boot to a live CD but when I install it won't boot because the PC's bios does not see the PCI card. This has to be possible but my Google foo isn't strong enough to find out how. Would a simple GRUB install on the pen drive work?

Hardware :: New SATA Drive Doesn't Allow Boot

Oct 1, 2010

I recently installed a PCI Sata card along with a SATA HDD and a SATA DVD burner. My PC ogirinally used /dev/sda1 to boot into root. But now when I plug the new HDD in, it names the SATA drive /dev/sda and the SCSI drive /dev/sdb.

I have unplugged the SATA drive and am able to boot into linux. I can also use the DVD burner. In the lilo.conf file, I have rename the root to /dev/sdb1 so when I plug the SATA drive in and reboot, it should go to sdb1 for root. But here is the error that Im getting.

2 OS's (CentOS,Ubuntu)

CentOS is in and running fine. It owns the MBR and was in place before I added the Ubuntu OS. Ubuntu was added to the free space of the second hard drive in partition 5 and its grub was installed there. So I thought this would work for a grub stanza.

Debian :: SATA DVD Drive Not Detected During Lenny Install?

Nov 17, 2010

I am trying to install Debian 5.0 "Lenny" on a PC with a very new hardware config (i3 processor, DDR3 RAM,LG SATA DVD drive, and Seagate SATA HDD). During the hardware detection phase of installation, I get a message saying the driver for my CD drive is not known, and asking me to select one manually. The options I get are only 'devcdrom', which does not work, and my installation cannot proceed.

I tried the following:

1. I read in a similar query that to use SATA DVD drives, I will have to set some boot options, so tried entering install libatapi_enabled=1 as an install option. This showed 'unknown parameter' error followed by same problem.

2. My Intel m/b BIOS has an option to set the DVD drive to "Native" or "Legacy", default is Native. I also tried changing this to "Legacy". Still same problem.

3. Read that I have to point to different drivers, but don't know how to do this during the installation.
