Mount: can't find /dev/sda2/mnt in /etc/fstab

I'm trying to install Arch on a virtualbox virtual machine to become familiar with it before I install it on my main system. I've created 4 partitions, dev/sda1=1007kB boot partition, dev/sda2/= 4gb root partition which I am trying to mount, dev/sda3=swap which I've already configure and dev/sda4=1792MB Home which I haven't mounted. I've formatted sda2 and sda4 in ext4, but whenever I run
mount /dev/sda2/mnt
I get an error message saying
mount: can't find /dev/sda2/mnt in /etc/fstab
I've tried to view fstab with the less command but I only got a bunch of tildes (~). I'm fairly new to linux so keeping the explanations simple would be appreciated.

The above post should fix the immediate issue you are posting about - but there is another issue:
VEL0CITY wrote:dev/sda1=1007kB boot partition
Is that a typo? Because that's not big enough for a boot partition. The kernel itself is 3-4 times that size. 100MB is a common starting suggestion for /boot. I can do with quite a bit less than 100MB, but not that much less.

Cant mount /dev/sda2 /mnt

hello,everybody
I'm a beginner
I want to install ArchLinux in my Dell notebook ,the sda1 had installed window xp,i want to make a dual system .
I burn a Arch Linux ISO cd and enter the live system,then the questions are coming....
After partitioning the drive by cfdisk tool,i cant mount the sda2 on the /mnt
the error code list this :
SQUASHFS error: Cant find a SQUASHFS superblock on sda2
EXT4-fs(sda2) : cant find ext4 filesystem
What's meaning ? I have partition the drive like this .Please other Linuxer help me or tell me how to solve this problem
cfdisk
name flags partType fsType size(MB)
sda1 Primary ntfs 30000
sda2 Boot Primary Linux 100
sda3 Primary Linux 10000
sda5 Logical Linux swap 2000
sda6 Logical Linux 70000

After you partitioned the drive, did you put filesystems on the partitions? Follow the steps in the Beginners' Guide, and use mkfs to put filesystems on the partitions. If sda2 is your boot partition, it's not the partition you want to mount at /mnt (you should mount your root partition there). Read the Guide.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

L can not find my playlist,play count, etc. on my new macbook itunes

I have recently purchased a macbook. i have about 22G of music oon my external hard drive. I have moved about 6G of music from my external HD to my macbook. I can not figure out how to get my playlist, play counts and ratings on the macbook. I do not want to add all of my original itune music 22G because i will be away with my laptop and i need the space for other things. I am not able to bring the External HD. I hope someone can help me with this. thanks

To transfer your iTunes metadata (tags, playcounts, playlists, etc) you need to locate and transfer the iTunes Music Library file from the original computer to the MacBook.
The easiest way to do that is to export the iTunes Library data as an XML file, email to yourself, and save it on the MacBook's desktop.
Now open iTunes and from the file menu, select Import, and navigate to the xml file, and select. This will add all of the data you are looking to put on the MacBook. However, you will get all of the songs - not just those that were added to the MacBook's hard drive. These will have the dreaded next to the name. If you can live with this, this is the easiest way to add your metadata.

[SOLVED] Trying to install Arch Linux from harddisk using /dev/sda2

Hi
I'm trying to install Arch using my swap partition, following this wiki entry: https://wiki.archlinux.org/index.php/Ha … stallation
What I've done:
Downloaded ISO: archlinux-2010.05-netinstall-i686.iso
Command: swapoff /dev/sda2
Command: fdisk /dev/sda and changed the system type to 83 (Linux) on /dev/sda2
Now it looks like:

It complained about device was busy, but it still seemed to have changed the system type, so I did partprobe as it wrote.

And unmounted it again.
The wiki page says to type: fsck -f /dev/sda2fsck, but I get no such file while trying to open sda2fsck.
[root@swamp ~]# fsck -f /dev/sda2fsck

fsck.ext2: No such file or directory while trying to open /dev/sda2fsck
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>
Can I ignore the above and continue modifying grub?
Thanks :-)

fsck -f /dev/sda2fsck makes no sense because /dev/sda2fsck is not a deivce. If the wiki says that, then it is wrong. It's only doing a fsck anyway so probably not really needed. If you are just formatting th swap partition then use, mkfs.ext{234}.

Mount usb: cannot find device

I have a compiled arch kernel. As there are some files in the /root, the user has enabled usb mounting.
as dmesg shows it identifies two usbs. one is plugged to keyboard.
I tried these commands, but they mounted folder is not my usb:
mount -t auto /dev/sdb2 /mnt/media
mount -t auto /dev/sda2 /mnt/media
in /dev I cannot see anything except
sda
sda1
sda2
sdb
sdb1
sdb2
what should I do to get my usb mounted?
update: I am trying to mount the device on sdb1 and sdaxx, but it only mounts /root filesystem into /mnt/media. I also changed the format type of usb to ext4 as this is the only filesystem module loaded into the kernel.

How did you compile your kernel? Were you using modprobed_db and following the recommendations?

ISA R3 develop where can I find the classes

Hi everybody,
I want to modiy Java classes from the ISA R3 shop.
I have unpacked the *.sar file which contains several ear files like b2b.ear, shopadmin.ear etc. I have unpacked this ear file. After that I have unpacked the corresponding war files. I thought after this steps I can find the Java classes. But there are only jsp and xml files.
Where can I find the Java classes (Beans etc.)
Is it correct that I have to unpack ths files with the jar.exe from the jdk and not with the ISA-BUILT tool?
Kind regard
Axel

Hi Axel.
   I suggest you that checks the notes in the forum of   Customer Relationship Management (CRM), in that forum comes all about ISA.
   For modify ISA you have to download de ISA Build Tool, you make your changes and after that you install the new ear application.
   All the bean classes in this applications comes in jar´s but you can extended the classes.. for do it, read the SAP ISA Development Guide
Good luck!

On a system without LVM, a filesystem is created inside a partition. fdisk is used to list partitions on disks. Because the filesystems are inside the partitions, you can use the name of parition to mount it.
On a system with LVM, a filesystem is created inside a logical volume, not in a partition. The partitions (fdisk -l) are used as physical volumes (pvdisplay), which are added to a volume group (vgdisplay), in which a logical volume can be created (lvdisplay). In the logical volume a filesystem is created. Because of this, only the logical volumes can be used to mount the filesystem.
LVM adds an abstraction layer between filesystems and partitions. This is extremely handy because it's easy to add a disk (which is made physical volume) to a volume group which makes space available, which can be added to any logical volume in the volume group. When that's done, the filesystem in the logical volume can be enlarged with resize2fs, even online. Without LVM, it's not possible or very hard at best to do that.

"Unable to find root device /dev/sda2"

Hi!
After an update - seemingly unsuccessfull - I get dropped into a recovery shell. The messages are:
/usr/lib/suspend/resume: /usr/lib/libpng14: version `PNG14_0`not found (required by /usr/lib/libsplshrender.so.1)
ERROR: unable to find root device '/dev/sda2'
I read that now I'm supposed to run a LiveCD and chroot something... can someone please be a little more specific here? I don't want to lose that system and I have no idea why it doesn't find my disk anymore. I just performed a pacman4 uprade, but it seems pacman4 is rather immature, leaving a system unuseable like that.
There is no sdaX in /dev any more. And I have very little experience with recovering Arch Linux. Until now
Best,
wishi

I have some wild problems here
1.) I used an Arch Live CD, did the chroot trick from the wiki (https://wiki.archlinux.org/index.php/Ch … nging_Root) and rebuild my initcpio (https://wiki.archlinux.org/index.php/Mkinitcpio). That ends successfull, and says it adds hooks for sata etc.
-> But I had to remove the udev hook: http://bbs.archbang.org/viewtopic.php?pid=11304 - I guess that's the reason why it still doesn't find my /dev/sda2 - I'm not sure this is related though.
2.) I ran pacman -Qk to ensure everything is sane. No errors. I reinstalled linux and udev two minutes ago. No change.
But I don't see how I can fix this. What's that voodoo with some udev hooks wandering around? The new kernel is 3.2.5-1 ARCH.

Not having very much luck finding the product you're describing but i'm more than happy to assist you with this.
I would assume since the OP is posting in the Touchsmart forum they are referring to the Touchsmart 610-1201 computer, no idea why you can't find it, the OP gave all the correct information.
OP you're probably looking for the #VK554AA adapter, but you will still need an additional VESA wall mount.
Google for "touchsmart wall mount adapter for vesa wall mount" and you'll see the many sources for this part.

Trying to put in a path and it can't find mount point

I am installing an application that is asking for a [hostname]:path to application and I have tried putting in path such as /NBU/Path and it can't find it. I have tried the local hostname with the local path and that hasn't worked. I am able to go to that path of course and it works, but for some reason the application can't find it. Any thoughts would be appreciated. Is there some other syntax that I might use?

What application are you having issues with? The path provided suggests this could be NetBackup or something which talks to NBU?? Read the installation instructions for the application in question as it will answer your question.
The 'hostname:/path' is the format used for NFS (Network Filesystem) mounts. If the app is being installed locally then there should be no reason to use NFS.
With the hostname being in square brackets it suggests it is optional.

Windows 2008 R2: SLES 11 Sp3 Guest converted from Vmware OVA to VHD, does not boot on Hyper-V: could not find /dev/sda4

Hi
I have a VMWare OVA file with Guest OS as SLES 11 Sp3. I have converted this file from OVA to VHD using Microsoft Virtual Machine Converter Solution accelerator. On first boot of this VHD on Windows Server 2008 R2 - Microsoft Hyper-V I get an error that
"Waiting for device /dev/sda4 to appear..
Cannot find /dev/sda4"
I have not even booted this VM once on Hyper-V, and hence not installed any Linux integration Services yet.
What could be the possible reason for this failure? Any suggested solution?
Thanks
Ashwini

Easiest way (and also applies to Hyper-V 2012 R2):
Ok, following properly (originally missed the step to mount the root directory of the converted VM as "/mnt" )
http://nwrickert2.wordpress.com/2011/10/24/rescuing-susie/
Then once chrooted
mkinitrd -d /dev/sda2
generated initrd from kdump WITH Hyper-V drivers & VM is usable!
http://forums.opensuse.org/showthread.php/476780-boot-failure-mkinitrd-does-not-understand-that-dev-sda-has-become-dev-sde
Can't believe that it was so painful to find the right info easily
Just to finish it off, after converted machine boots fine, there is a small
matter of removing tools & fixing networking as per links below:
https://pubs.vmware.com/vsphere-51/index.jsp?topic=%2Fcom.vmware.vsphere.upgrade.doc%2FGUID-6F7BE33A-3B8A-4C57-9C35-656CE05BE22D.html
http://www.vcritical.com/2010/10/getting-eth0-back-in-a-sles-for-vmware-clone/
All done!!!
Also (unsupported), but works fine is SLES 11 SP1

Mount: can't find /dev/sda2/mnt in /etc/fstab
