Hardware :: Change LVM Disk Sata Port?
Oct 18, 2010
I have Linux system with 6x500 GB sata drives on LVM. I want to change 1 of the disks with larger - 1 TB. I don't have available free sata ports, so I'll add pcie sata controller. I'll add the 1 TB disk to the pcie controller and will use "pvmove" to transfer the PEs from one of the 500 GB drives to the new 1 TB. Then I want to remove the 500 GB disk from the LVM. I want to remove the physical disk from the box and to place the 1 TB disk on its place. But I don't know if the LVM will recognize the disk? I want to remove the pcie controller from the box because the motherboards sata controller is better.

I'm looking for recommendations for a controller card with support for around 8 devices using SFF-8087 cables. I currently have a AOC-SASLP-MV8 [URL] which while working "OK" still has known problems with drivers. Can anyone recommend a card they use for a storage box? I'm using software raid.

VERY new to linux, erm but I have an issue that needs solving!I recently moved to university, where their network blocks sftp port 22, this means that I cannot connect to my FTP server which is running a version of linux.Now I've got this ftp server connected to a seedbox and it was created using the following walk through..Code:I have written this guide for a friend, but I though it would be useful for others as well.
There are several guides floating around, but I found that most always cock up in some way. This one is tried and tested to work on Debian Etch (on an OVH rps, but should apply to most servers).If there is a new stable release of rtorrent/libtorrent then I will update this guide to show you how to update it (without reinstalling the whole server).
At the bottom there are also instructions to install ftp access & some network monitoring software.Basically, I would really like someone to be able to construct the commands on how to change the listen port for sftp connection on linux or add another port to the list that Linux would use so that I could put in through putty.

My computer has 2 HDDs attached to 1st and 2nd SATA ports of my mobo respectively, the 1st SATA drive is empty while the 2nd have my Windows Vista on it. I also have a Perc/5i RAID card with 2 RAID arrays defined.
I am going to install Ubuntu 10.04 x64 to the 1st SATA driver (I expect it will be /dev/sda), but when I try to install, I found my drives are recognized as below,
/dev/sda > 1st RAID array of my Perc/5i
/dev/sdb > 2nd RAID array of my Perc/5i
/dev/sdc > 1st SATA drive < I need to install ubuntu on this drive
/dev/sdd > 2nd SATA drive
I don't want to install 10.04 as /dev/sdc because I may add more arrays to my raid card which from my experience of 9.04, it will probably change the drive letter of my current /dev/sdc and then system will fail to boot.
Is there any way to force my 1st SATA HDD as /dev/sda during install ?

I have a trayless SATA hotswap bay that is really terrific for quickly attaching and removing SATA hard drives. I'm trying to write a udev rule to create a symbolic link to the device node for the drive that is attached through the hotswap bay (/dev/bay -> /dev/sdX). This eliminates any ambiguity when performing destructive tasks (fdisk, etc). I'm running squeeze amd64. I've read through several tutorials and have it working somewhat. Here's the output of udevadm info for a drive attached via the hotswap bay.
looking at device '/devices/pci0000:00/0000:00:11.0/host7/target7:0:0/7:0:0:0/block/sdb':
KERNEL=="sdb"
SUBSYSTEM=="block"
DRIVER==""
ATTR{range}=="16"
ATTR{ext_range}=="256"
ATTR{removable}=="0"
ATTR{ro}=="0"
ATTR{size}=="156301488"
ATTR{alignment_offset}=="0"
ATTR{capability}=="52" ....
Here is my udev rule
DEVPATH=="/devices/pci0000:00/0000:00:11.0/host7/*", SUBSYSTEM=="block", SYMLINK+="bay%n"
This produces the desired behavior and gives me an fdisk-able device node. The problem I am having is that the "host" component of the DEVPATH varies from bootup to bootup. I'm just using on onboard SATA, host2-7, specifically host7. There is also onboard PATA, host0-1. It seems to just be random which "host"s are assigned to which controller. For example, the next time I boot the system, the onboard SATA will be host0-5 and the onboard PATA will be host6-7. In this simple case, I could just write 2 rules, one for each possibility and it would still be correct because of the different PCI addresses of the two controllers. But on systems with more SCSI (uh... libata, actually) controllers, a "host" file can point to different physical ports between bootstraps. This would be bad. Does anyone know of a way to write a rule to tie a device node to a specific physical SATA port on the motherboard/hba?

I've got an Addonics AEIDDSAU multi-flash reader/writer that uses the SATA port LINK. I'm running XUbuntu 10.04, 64 bit on an Intel DQ45CB motherboard. The board has 5 internal SATA-300 ports and one external eSATA-300 port. The Addonics reader works fine on the eSATA port, but it doesn't work (properly) on an internal SATA port. By "doesn't work properly" I mean that when connected to the eSATA port, plugging in a memory card causes an immediate detection and the contents of the card pop up in a window (as they should).
When connected to an INTERNAL SATA port, a plugged in card does not show, and using CFDISK to look at the "drive" shows an unformatted 64MiB disk that really doesn't exist. Being an INTERNAL device, the Addonics reader is rather worthless if it doesn't work on an INTERNAL port, and there's no clean way to bring the eSATA port inside the computer. By the way, I'm sure this is NOT a "Linux" problem because the reader behaves the same way in Windows XP.

I have a SSD Harddisk with both an usb and Sata connection, and I want to be able to boot both from usb and sata but I can't make it work. When the disk is connected with sata anything works fine but when I connect it with usb instead, Fedora seems to boot but then it gives me an "No root device found" error and just sleep forever. This happens even if I install fedora 13 while the disk is connected with usb. I am running Fedora Core 13. I changed my fstab to
/dev/sda2 / ext4 defaults 1 1
And the disk is still booting when connected to the sata controller. So far so good. But if I boot from the usb connection, it still give me the same "No root device found" message. Even more odd is it that if I boot my fedora core 13 dvd, and choose "rescue installed system" it can't detect the harddisk when connected to usb. And there is no /dev/sd* or anything similarly which could look like a blockdevice. Did redhat forget to include usb drivers in their rescue image for Fedora core? I just tried the disk on an other system, with exactly the same problems.
I have now added the LABEL=myroot line to fstab(I guess it have to be uppercase to work) and the harddisk still boot fine when using sata, but it still can't boot using usb. I begin to guess that redhat forgot some usb drivers In fedora Core 13, because the system can't see the harddisk when booting the dvd and entering rescue mode. blkid don't show any harddisks at all and there are no block devices in /dev/ which might be my usb disk. Is it possible to find the uuid of partitions if id add the usb harddisk to a windows computer, and more important: will this be the same uuid as linux will se.

I bought 2 new 1,5TB sata disks for my server. But when I plug them in my debian gives a error message: ata2: SRST failed error -16
The debian runs from an old 500GB ide disk and a 160Gb ide disk for the home dirs.
I tried antoher cable, but that is not the problem(or is that other cable also broken...). I also tried all sata modes in bios, auto, enhanced, sata-only. I also tried booting an ubuntu 9.10 live cd. But in gparted the disks won't show up.
Is it possible that the sata controller of the motherboard is to slow.

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")

I have a 3.5" SATA disk in an external enclosure which is connected to my USB port. How do I get F13 to recognize the disk? It does not show up in the Disk Utility (Applications > System Tools > Disk Utility).
F13 does recognize flash drives that I put into a USB port.

Is this a known bug? I've not had problem installing 9.04 but 9.10 will not see HDD under partition manager(ubiquity) no matter the F6 boot options or fiddling around with bios. If ubuntu can't see the hdd, I can't install. 785G chipset with SB710 FYI.

I'm trying to install 10.10 on a sata disk. In terminal, dmesg recognizes the disk at /dev/sda. The installer recognizes it as well, but the partition area is blank and the option are greyed out. How can I go on? BTW, on the disk currently Fedora 14 is (fresh) installed and working fine, but a software install script is written specifically for Ubuntu. That's why I need to change to Ubuntu and it's no hardware problem.

I have a problem to boot from a SATA disk. The filesystem image was created by our customer and copied to the SATA disk. It is SLES 10.2. When booting, "waiting for /dev/sda2 to appear" appears. The filesystem seems not to be corrupted, it can be mounted via a live CD. Here are the files I consider being useful for you.

All of my computers are second-hand (except 1 laptop but it doesn't count) and I see in my Dell 4600 there are 2 SATA connectors on the motherboard. I picked up a 250 GB SATA hard disk and cables recently and tried plugging it in but the system doesn't see it. I even disconnected all other disks to make sure there wasn't a conflict (master/slave) issue going on but the system still does not see it.
The disk is vibrating so I assume it is getting juice and is spinning. Is there a setting or something I have to do to tell the system to access the SATA? Do I have to look at RAID settings if there is only 1 SATA disk? Can I not have a SATA disk and an ATA disk plugged in at the same time? I want to try and determine if the disk is bad, or is it PEBKAC!

I have Etch running in my laptop. I found that if the laptop is only running on battery, the disk seems to performs slower than if I running on a power adapter. How do I possibly check the setting and fix it?
I'm the only user on the system most of the time and I keep it as minimal as possible so it's not other services and programs keeping the disk busy.

I recently updated from Lenny to Squeeze. In Lenny I used to spin down my internal SATA backup drive like this:
# sdparm --command=stop /dev/sdb
It worked well in Lenny, but it doesn't work in Squeeze:
XXXX:~>sudo sdparm --command=stop /dev/sdb
/dev/sdb: ATA WDC WD2500AAJS-2 01.0
All I can hear is a click indicating drive head movement but the disk keeps spinning.

This is a solution to a problem that has bugged me for months but I finally got around to solving.I hope this will be useful to anyone using Ubuntu with GRUB2 who has the same problem.I am running Ubuntu 10.4 Lynx which did not recognise the newly-installed SATA HDD.In fact, booting up would face me with a recovery shell.The solution is to add the pci=nomsi kernel parameterTo do this you need to edit the /etc/default/grub file and add the kernel parameter as follows:
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="pci=nomsi"

I have three disk in my system. One SATA (250GB) and two SCSI (73GB) disks. The Two SCSI disks were installed originally and RHEL3 is installed on it. The SATA disk is installed a few years later with RHEL5. As you can see below, the boot sector is still on one of the SCSI disks (sdb1).
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 236545184 15259760 209075624 7% /
/dev/sdc2 68539636 4578792 60479160 8% /users

tmpfs 2025916 652 2025264 1% /dev/shm
How I can move the boot sector from the SCSI disk (sdb) to the SATA disk (sda) without losing data and without re-installation?
