CentOS 5 :: 5.4 - Unable To Detect And Mount The Ext3 Hdd
Mar 1, 2010
I have a external usb 20Gb hdd. It was a ntfs partition but i could'nt mount it, so I try with a ext3 partition, because with centos it's mount automaticly, but... for some reason that I don't know, even with a ext3 partition my centos don't detect my external usb hdd, howerver I already try to mount it on ubuntu to see if it work, even on windows with some programm to recognize ext3, it was alright, but why can't i mount it on my centos?
I created a encrypted volume on top of software raid1. These are my steps:
1. Create logical partition on sda
2. Create logical partition on sdb (same size)
3. Change type to partition to 'fd' for both partitions
4. Check that the both partitions are same size and type fdisk -l /dev/sda && fdisk -l /dev/sdb
5. partprobe
6. Make sure there are no remains from previous RAID installations on /dev/sdb by running: mdadm --zero-superblock /dev/sda6 mdadm --zero-superblock /dev/sdb6
Running Debian Squeeze, I used gparted to wipe the fat partition on a 8GB USB thumbdrive, and repartitioned it with ext3. Everything goes fine, and gparted and fdisk -l both show the correct partition, but I can't seem to mount it, and automount in gnome fails as well.code...
I am unable to boot my server and it is erroring with the message "Kernel panic - not syncing: Attempted to kill init!". Here are the details:
I have a brand new Dell PowerEdge T110 server with Quad-Core Xeon CPU and 2GB 1333MHz RAM. I have installed a hard disk (SATA, 7.2rpm) on this machine that I removed from another Dell PowerEdge T100 server with Dual-Core Xeon CPU that was running software RAID 1.
Now when I boot the new T110 server, it displays the following error messages code...
I am running CentOs v5.5 x86-64. If I put the hard disk back into T100, it boots fine. I do not know why it is not working with T110 server.
I am using CentOS 5.5.I suppose this is an oft repeated question. I accidentally deleted, using rm command, 2 wmv files. The files were in a single ext3 1Tb drive, with just 1 partition --- the ext3 one. Each file is 600 - 800mb. The 1Tb drive has only about 20Gb data.Immediately after deleting the files i unmounted the drive (/dev/sdc1). Thereafter i searched the the net and came to know of the recovery tools foremost and photorec. I have installed both of them. I am currently running both of them as root --- foremost is just showing a lot of * signs on the terminal and photorec has managed to find some txt and png files --- but no wmv.For foremost i used: /usr/sbin/foremost -t wmv -i /dev/sdc1For photorec i followed some instructions available on the web.
In the meantime, based on some post on the net i ran debugfs as root, then cd into the directory where the files were deleted. Then on typing ls -d i managed to get the inodes of the 2 deleted files and the names of the deleted files are also correct. The instructions on the net http://www.theavidcoder.com/?p=3 tell me to run fsstat and dls both of which i am unable to find in /bin, /usr/bin, /usr/sbin and /sbin. So i am unable to proceed further.
I got a CentOS server + KDE from a server (which I had no contact until now), he had 2 HD's one for the system and another for files.
I brought the HD system home to try to make it run on a virual machine (VMware) so I can do some testing before you put in practice.
But already converted the VMware HD to the system, it tries to start but it shows some errors and in a message "kernel panic - not syncing: attemped to kill init"
I think the drivers are correct, has edited the file "/ etc / modprobe.conf" edited these entries equal to another I installed CentOS on VMware.

14. Mount the encrypted volume: mount -O noatime /dev/mapper/ftdata /ftdata
It mounts successfully this first time. When I cd /ftdata, I can see the lost+found dir
Now, I unmount the volume cd ~
Code: umount /ftdata cryptsetup remove ftdata
And now, if I try to setup my encrypted volume like this:
Code: [root@localhost ~]# cryptsetup create ftdata /dev/md4 Enter passphrase: mount -O noatime /dev/mapper/ftdata /ftdata I get this error: mount: you must specify the filesystem type
I am trying to mount a nfs share which is located on my freebsd server to new centos 5.4 server but something wrong. If I try to mount nfs share on bash "mount -t nfs server: /mnt/fornfs /mnt/nfstemp/" It is working properly. But when I put a line in fstab like this "server:/mnt/fornfs /mnt/nfstemp nfs nfsrsize=8192, wsize=8192, timeo=14, intr, tcp 0 0" It do not mount the share. How can I mount it at startup?

I have a working Windows XP machine. I've installed a second hard drive (channel 1, slave to Windows XP master) and installed Centos (having checksummed the images and verified the media). Problem is it will not boot.
The exact text on screen is...
Booting 'Centos (2.6.18-194.el5)' root (hd1,0) Filesystem type is ext2fs, partition type 0x83 kernel /vmlinuz-2.6.18-194.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
[Code]....
I've managed to use the "Linux rescue" to at least ensure the box default boots to Windows. how to get Centos to boot.
Also, given I told Centos where to install to, and I've not changed anything since, how come it could not even manage to create a working system? Never had this problem on Windows (OK, always on Windows 98 but I never considered that an O/S ).
Booting to CentOS 5.5 works and I am able to login with all my devices mounted. When I boot from the install DVD and type "linux rescue" I eventually get the message, after attempting to have one of the screens mount my partitions in read/write mode:
"An error occurred trying to mount some or all of your system. Some of it may be mounted under /mnt/sysimage." But nothing appears mounted under /mnt/sysimage. Should I try mounting my CentOS 5.5 partitions manually at this point ?
I have a Western Digital World edition II network HDD, but somehow I have lost the Media folder..I have also read http://foremost.sourceforge.net/ is a very great recovery tool in ubuntu, is this true?So I have pull out the HD from the western digital NAS case and put it into a USB enclosure.Anyone can teach me how to mount this driver?To look for device boot namesudo fdisk -lBut how to look for the mount_point_dir?sudo mount /dev/sdc4 [mount_point_dir] -t ext3
I just made a new storage partition and formatted it as Ext3. Now, this particular partition is shown and can be read at the terminal "fdisk -l". However, unlike in my Mint 7 partition, it does not show in my Fedora 10.
Code: [jun@localhost ~]$ sudo fdisk -l [sudo] password for jun: Disk /dev/sda: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xc5e3f820

This partition can also shows be seen in gparted in Fedora. However, even in the "Places" tab, it does not show.
I have bought a ICYBOX IB-NAS4220-B a while ago and kept getting issues with it (going down and not restarting, very slow etc). 2 weeks ago one more issue arose and I couldn't restart or reconnect to the box so decided to take the disks out and recover my data to a 5BIG Lacie. The IcyBox uses a software RAID1 and format drives in EXT3. Being a Linux system I thought I could easily recover data from an Ubuntu box so installed the latest version as CD boot wouldn't give me satisfactory results. I am now stuck with both 1TB drive plugged into my Ubuntu machine and can't seem to be able to mount the drives.
I installed NFS and portmap for export a folder to another PC. /usr/local. ftp is server's hostname and ws01 is client's hostname. I edited file /etc/exports with next text: /usr/local ws01(rw,root_squash) *(ro)
I restarted service portmap and nfs. From client, I try check connection with server with command: showmount -e ftp and result is: mount clntudp_create: RPC: Port mapper failure - RPC: Unable to receive
i am trying to get centos 5.4 installed and bootable on my 16gb flash drive, with persistent overlay using and ext3 formatted drive.i want to be able to boot into centos and be able to have all updates from yum, etc, saved when shutting down for my situation i cannot use vfat.
I'm fairly new to Ubuntu and I'm running Karmic Koala. I just reformatted an NTFS partition to Ext3, as I no longer need to access is from my windows installation. Now I'm unable to mount it though, and I get the message: Error mounting: mount exited with exit code 1: helper failed with: mount: only root can mount /dev/sda6 on /media/DATA2 (DATA2 being the name of the previous NTFS partition. Now the label is linuxdata)
When I try to mount it using sudo in terminal I get the following message if I use the label DATA2:
NTFS signature is missing. Failed to mount '/dev/sda6': Ogiltigt argument The device '/dev/sda6' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
And if I use the label linuxdata: mount: can't find /media/linuxdata in /etc/fstab or /etc/mtab I've tried to search for help, but been unable to find an explanation.
I'm trying to mount a second hard drive as a ext3 (rw_acl,user_xattr). I type the ff.:
# mkfs.ext3 -c /dev/sdb1(it seems to create a file system from this 2nd HD)
then type:
# mount -v /dev/sdb1 / type ext3 (it seems to mount it)
But when I check the ext3 systems with typing:
# mount -t ext3 (to check the list of ext3 devices, it gives me this) /dev/sda1 on / type ext3 (rw,acl,user_xattr) /dev/sda2 on /home type ext3 (rw,acl,user_xattr) /dev/sdb1 on / type ext3 (rw)
How can I make /dev/sdb1 on type ext3 as (rw,acl,user_xattr) as the others?
I need to copy data from a single HD, which used to be part of a Linux RAID 1. I've googled around, but can't find any clue how to mount partitions from this single HD.
Background: The HD comes from a linux based NAS box Synology DS207+. The NAS uses ext3 as filesystem. Both NAS disks are fine, but the other NAS hardware is dead and not worth repairing or replacing.
I attach a picture of my future disk partitioning,as I thought it should be. As you can see, the first two partitions are 2 different windows installations. At the end of the disk, I have specified a partition as ext3 104855 MB (sda9) and swap 8192 MB (sda. What should the the mount point of sda9 be? Should I specify a partition for /, /boot, /home, /tmp, ...etc? Or it is ok to make mount point '/'?
With a 1Tb USB drive plugged in, we'll call it "TheDrive", I boot my machine and "TheDrive" is mounted automatically. The icon is on the desk-top. "TheDrive" mounts to /media/TheDrive. Everything is fine. But, I would like to automatically mount the drive in my file tree at the location /mnt/TheDrive. I would not like to have the drive automatically mounted to /media/ and appear on the desktop. I know that this requires the use of fstab; but, I do not know what to add to this file.
I have dual boot system..i.e, windows XP and ubuntu 9.10(insatlled side by side). when i try to boot ubuntu, Im gettin sh:grub > prompt
[Code]...
I am getting something like this.. root mount file system failed.. ext2 ext3 ext4 ....... kernel panic message and hanged at kenelthreadhelpper+ what can i do.. I cant reinstall ubuntu again.. Because I have installed nany application there..
I'm trying to install ubuntu-10.04-server-amd64 from a 2gb usb stick. I used Universal-USB-Installer-v1.7.7 to put the contents of the iso onto the usb disc, the installer boots fine but it always fails at "Detect and mount CD-ROM". Any suggestions? I thought about trying to mount the usb stick (/dev/sdb) to the where the installer is looking for the CD-ROM but I don't really know where that is.
I am trying to install Fedora 11 in Virtual Box using the Live CD. When I try to format with EXT4 (Default) it says the boot volume cannot be EXT4, when I try EXT3 it says it doesn't match the Live filesystem. This is retarded it won't let me use either. (I don't usually throw around the word retarded, only in rare cases and this is one)
So I am trying to install ubuntu server on to a sony vaio laptop (long story in and of itself) I have a few questions the first and most important being this: 1. What is the module and /dev/ I am supposed to use to get it to recognize the drive? It kind of dumb because it can't read the drive that it's installing from ya'know? The drive is a sony nec optiarc AD-7560S the vaio is a VGN-NS110E all stock equip except the hardrive.
2. Keeping in mind that I may..probably will move the hdd to a netbook what are ALL the module I will need to finish the install and how do I add them in (can I use a usb or do I have to re-burn the iso)
3. What do I need to do to get the built in remote desktop to run once the install is done and most of the software is taken care of. Also I need to be able to install stuff from the remote computer and said remote computer may be holding the program. I am also looking into rdc-ing from my andriod (tmobile g1)
