Debian :: SATA Raid, /home Partition Mounting Error?
Nov 9, 2010
I've installed debian squeezy recently and for some reason I have problems with mounting /home partition during startup.
There's an error:Mounting local filesystems...mount: special device /dev/mapper/isw_bbfedcffgi_Volume0p6 does not exist. failed
I've tried using fsck - no result the file system is healthy, I've tried formatting it once again (fresh copy, no user data) and it's not working. What is more mounting the partition manually goes well - I can read the data and write to it. All other partitions are ok.
I have no idea what's going on and why mounting /home fails. I've written this post on Polish debian users forum, but no response - only to give more info, so I'll put it here also:
ls -al /dev/mapper

i decided to try archlinux in my pc a while ago so i installed it... after three months i started to miss slackware so i decided to reinstall it but i wanted to save my /home partition so when i installed slackware i left my /home partition from arch hoping that i could just mount it on slackware...but now when i try to mount that /home partition this is what i get:
bash-3.1# mount /dev/sda4 mount: wrong fs type, bad option, bad superblock on /dev/sda4,missing codepage or helper program,or other error In some cases useful info is found in syslog - try dmesg | tail or so code....
So i dont really know what is going on here but i hope somebody could help me because i really NEED to get the data from that partition.
oh and by the way i installed slackware on ext4 partitions and the /home partition from arch is ext3 so i dont know if that's maybe the problem o_O?
I'm having some problems with a hosted openSUSE 11.2 server. It was running fine until I did a "zypper up" to apply patches. This included a kernel update.
On reboot the root partition does not mount the / partition giving the following error:
Unrecognized mount option "defaults.noatime", or missing value mount: wrong fs type, bad option, bad superblock on /dev/md2.
Through an Ubuntu rescue disk (this is what Hetzner provides) the disk can be mounted without problems.
( I installed a fresh openSUSE 11.2 with a similar configuration and got the same results after the update)
The server is a hosted installation from Hetzner in Germany with just the basics for LAMP setup.
The disk setup is as follows using software raid1: swap /dev/md0 (/dev/sda1 /dev/sdb1) /boot /dev/md1 (/dev/sda2 /dev/sdb2) / /dev/md2 (/dev/sda3 /dev/sdb3)
Have Lian Li Ex 503 External Raid System, using 4x2TB, using Raidmode 10 for good performance [ Just for those who are interested: http://www.lian-li.com/v2/en/product/pr ... ex=115&g=f ]
[Code]...
But using e-sata my transfer rates are very low (from internal drive to external ex503), around 60-70mb/sec But hdparm tells me:
I want to stop using Windows because it sucks so i have downloaded all kind of distibutions from Linux. They give all the same error because it seems Linux has problems with Fakeraid. Now i have running OpenSuse in VmWare 7.0.1 but i want it as the only OS.
The installation goes fine but in the end it gives a Grub error because it cannot create the bootloader. It seems to be a common problem and i have done all the steps that i could find on Google.
I have two raid controllers. One is integrated in the mainboard from Asrock ALiveNF7G-HD720p R5.0 and OpenSuse sees it as a Jmicron controller.I have bought also a EM2001 2 Poorts PCI Controller SATA card with two harddisks in Raid 0 because Linux failed to install on the JMicron. On the EM2001 2 Poorts PCI Controller SATA it also fails with the same error.
I want OpenSuse 11.2 working on Raid 0. I know it must be some simple commands in the terminal through a live cd to correct the bootloader and do it manualy by Linux users but i'm a Windows user.
Can somewhone please tell me the exact steps and commands to install Linux on Raid 0 Fakeraid?
i am having troble with the permisions of a partition(/dev/sda3) that i have mounted as /home/stewi and wish to use it as my home dir, the only probolem is that it only lets the root user do anathing with the partition wen it is mounted as /home/stewi. i have tried running
Code: chown stewi:stewi stewi and Code: chmod 777 stewi while root, but i just get an eror mesage:
My "Home" server is getting ful, I've got one 1tera-disk and now I wan't to secure all data with raid 5 config. Can someone recommend a good "fairly"-cheap RAID5 SATA card?
I have attached a 2 TB LUN to the HP Blade Server running CentOS 5.3 via a Qlogic HBA. To provide the cluster users with sufficient storage areaa, I want to move only the home directory from the default partitioning schema to the attached storage and leave the remaining partitions on the main harddrive of the server. So, having copied user directories & files to the new location, i.e., /cluster/home2 on the new storage partition, what modification(s) should I make on the server? /export/home is the default location for the users. /cluster/home2 is NFS shared directory serving as the new home location for the users.
I received some errors while running a benchmarking script to determine my ideal raid chunk size. There are several errors in the kernel log regarding the sata link and eventually the two drives i have connected to a pci express x1 sata card were no longer present in /dev/
the script i was using is available here [URL]..system specs 1 500gb western digital drive (system drive)3 2tb samsung f4 drives (2 connected to pci x1 card (sata II) and 1 onto onboard sata port (sata I)) single core amd 64 on SiS chipset debian 64bit testing

I rebooted the machine and everything appears to be happy. What do these errors mean? What steps should i take to prevent them in the future so it doesn't end up corrupting the array?
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 2 hard drives on mu box 1st one is 500.0 MB ext4 Volume where I have my syste FC 13 and a 2nd one where I put my database files as follows 78.1 GB ext4 Volume usage = filesystem, format ext4
ih file browser, I can see an icon for a 80GB hard drive but whenever I double click I get the following

What is very strange is that mysql works fine.In disk utility, it indicates that disk is healthy, but when I click check file system i get

The installer can't see my raid controller (I assume) as I'm getting the following error:"Error opening /dev/mapper/isw_jbhgjgjj_Vol0: No such device or address"It just sees them as 4 individual drives: sda, sdb, sdc and sdd.Please note that I have set up the RAID 5 in the controller bios interface and the image name is Vol0, which it seems that it tries to load but for some particular reason it can't.I have also tried different bios settings and nothing worked.
I have a dual-boot setup with winXP and openSUSE 11.2. I have both XP and SUSE partitions on a 160g HDD and then a Hardware RAID 1 array of 2 320g HDDs. The RAID arrray contains all my media/data files on an NTFS partition. For some reason SUSE shows both individual 320g disks mounted in the file system, but not the RAID array. If I attempt to browse either of the disks, I get an error and can't view them. How do I mount the RAID NTFS partition?
I have one of my user's home directory on a seperate partition, and I was wondering if there was a way to only mount it when/if the user is logged in and unmount it if they log out.
My debian 5 is up and running smoothly and act as file-server in the middle of windows network jungle using samba the only problem is, after backup an external hdd (213 GB) to my /home partition, I end up with message say that I'm running out free space. Fyi my debian installed on 1TB SATA disk, and I separate my /home partition from system what happen to my free space ? here is screenshot of my disk, using disk usage analyzer: is there is a way to get my space back or something missing on my setup.or I have to reinstall my debian and use LVM when partitioning my disk?
This was a really frustrating problem which turned out to have a really simple solution, so I'll share it with people who might be having the same struggle. Problem You plug in a usb hard disk and try and mount it using:
[code]....
I spent hours - days - hunting around for the solution! (And felt a bit humiliated when I realised how simple it was!) PS, There used to be a "Success story" section on LQ, but I couldn't find it; if this is better in another section, please move it. PPS, I'm on a public computer and won't have Linux access for a looong time - if anyone can copy the message that fdisk prints out to help people who are searching for it
I have just configure RAID 1 on my IBM X3400 Server in CENTOS 5 ..Partition information is md0 boot , md1 swap and md2 is root ....but after resyn when i run cat /proc/mdstat I realize that md0 and md1 is ok and present with [UU] status. BUT the md2 is showing on one [U_].. that means my root partition is not properly in RAID 1.. how can i make it active in both drive. Or i need to reinstall complete system again.

Installed Ubuntu along with Debian on my Notebook and use Grub Manager to choose between them on startup. Since i like Debian now a lot (in past days it was a very hard system to handle, but there has been some progress i noticed), i have to change some things (want Debian as main system now) For Ubuntu i have: (was meant to be main system on Notebook) "/", "/home" and a "swap" partition, but since i am now going to use mainly Debian, i wanted to store my files all in the "/home"-folder of my extended Ubuntu partition (has much more space available) not in the "/home" folder of the Debian system. So i want both (Debian and Ubuntu) to use the same extended partition ("/home") which i created for Ubuntu to save their files like downloads, videos, and so on.
I have Linux Mint (LMDE) on another partition and I guess I need to do some 'fixing' so I need to mount the partition. I can't, though, not by just clicking the partition (obviously?). I assume this is because I need root access to mount it.
how I can do this?:
1) CLI - mount via CLI by mounting at some point - for e.g., mine is /dev/sda3 so mount as ?
2) Use an 'editor' or file manager - such as Dolphin - how would I do this?
3) Use a Live CD/DVD - I think this way is unnecessary but it's a way, right?
Anything I missed? I guess gparted could mount it?
Which method would you use?
I think one could ssh into it but I'm not able to do that yet.
I need to exit the xorg.conf file which is recently really messed up.
Trying to clean install 11.2 dual boot with Win xp already installed. How do I create a new home partition, don't want to preserve the existing home partition from a previous attempt. DVD installation and automatic config keeps saving the thing.
i used to have ubuntu 9.i decided to move to sabayon so i used the live cd to install it ,resize the ubuntu partition and use the remaining space for sabayon.while the resizing procedure i got an error(i dont have a copy of the error log file but i know it has something to do with an anaconda process).i aborted the installation and the result was an filesystem that couldnt be mounted.when i try to mount the hdd i get this:
Code: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so and this is what i get from fsck: Code: $ sudo fsck -f /dev/sdb1 code....
The RAID level 1 interested me because of its redundancy in both drives. And I successfully made it in a couple of partitions. But, I always did it after Linux installation. Then, I create both partitions, use 'mdadm' to create raidtab and RAID device (md0, for example) and then I format the RAID device with 'mkfs' and mount it.
Until there, it's all OK.
But my problem is to mirror ALL the hard disk, inclusive root partition. To do that, I guess I need no Linux installation, then create the RAID (md0, raidtab, etc) and after that install Linux in RAID device created.
But I'm new in Linux world and I have no idea how to do that.
I use Debian Lenny, so I need a solution that uses only the first DVD of this distribution.
My motherboard supports SATA but I do not know which version: SATA-I or SATA-II. I want to buy a SSD so it would be pointless to buy a fast SSD if my motherboard only suports SATA-I
I have recently installed Debian on my NAS server. I have also configured Samba for sharing the home directory of a nas user i.e. /home/nas To this directory I have read/write from a windows machine using the nas user credentials. When I mount my RAID partition /dev/md0p1 to the /home/nas directory, I then realize that all content in this directory (files and subfolders) is only owned by the root user. When trying to access from the windows machine the /home/nas directory, I do not have any write access, only read. I have tried both the nas and the root user credentials.
I have also attempted the change the ownership of the mounted RAID partition to the nas user with the -R recursive option, but I get for the internal files/subfolders an error "operation not supported".
How can I overcome this problem? - Is there something not done properly in the /dev/md0 array definition (i.e. ARRAY /dev/md0 level=raid1 num-devices=2 UUID=bddf8b69:c97967b5:cb104784:7fef7cc3 )?- Is there something not done properly in the /dev/md0p1 mounting (i.e. mount /dev/md0p1 /home/nas)?- Should I do any extra configuration before the mounting etc? I would really appreciate any kind of help I could get.
Some background info
b) After OS boot, when I do a: # cat /proc/mdstat, I get: Personalities : [raid1] md0 : active (auto-read-only) raid1 sda1[0] sdb1[1] 4200896 blocks unused devices: <none>
concerning Linux, mdadm, and creating RAID Array's in Debian. I've done a lot of reading and research on RAID both on this board and elsewhere (The Linux Documentation Project's Software-RAID HOWTO is especially good), but I've run across something that no one seems to explain, and I'm not sure why. I'm instructed to create partitions on the drives I wish to add to my array. These partitions inevitably take up the whole disk, and are always have their system IDs set to "Linux raid autodetect". What I don't understand is why, after creating these partitions, some guides then go on to create an array (say a RAID5 one) with just the disks themselves as members, while others go on to create the RAID5 array with the previously created partitions as members. E.g.,
I'm trying to mount my SATA drive that has Windows on it under Xubuntu, it's NTFS formatted, I tried adding it to fstab, I know the /dev points are right I checked with sudo lshw -C disk and with fdisk -l, the drive is partitioned 3 ways 1 for Win7, one for Win7's system info partition or whatever, and 1 for documents, but when I try mounting with mount -a with /dev/sda1 (which is where the windows partition should be) I get this:
extended sata partition shrunk at 15 partition limit, how to re-enlarge i hit the 15 partition limit, forgetting it now exists for sata drives, thinking i would add more. upon creation of the 15th, it squished the end of the extended partition to meet the last logical partition, leaving a large unallocated portion after the extended partition, which seemingly nothing can be done with, just sat being wasted space. i have since deleted a few of those partitions, but so far have still failed to find a way to recoup the unallocated space back into the extended partition.
[URL]
if necessary, i'll do it the painful long winded way of backing up and starting the extended partition again from scratch, but i really rather wouldnt have to do that. i'm sure there must be a way of telling the extended partition to once again reach the end of the drive.
