General :: Win7 Can't See Shared Storage Partition
Aug 7, 2011
I used to have three partitions: Win7, Fedora 12 and a NTFS-Storage-Partition.Now I had to reinstall Win7, it doesn't see any files on the storage partition;Windows shows the whole rest of the disk including the linux partition as one drive with 7gb of 80gb free, I can also open it but then there is nothing in it.Linux is still working and everything on the storage partition is still there and accessible in linux.any suggestions? do i have to tell windows the partitions or does it have to do a scan or something?

Ive been asked to investigate presenting the same SAN LUN to two or more RHEL5 hosts. The hosts are providing independent applications so theyre not clusters from an application perspective. The shared storage location would be used as a common area for imports/exports. Were hoping to reduce file transfer times between the hosts by eliminating the need to copy the files between two storage locations. Some of our hosts run Advanced Server and some are standard. Is there a file system that I can use that will allow multi-host access without running advanced server with clustering services on all hosts?

What is the current state of NFS failover (i.e. setting up two server with shared storage, with automatic failover if one fails?) I've seen a cookbook, but no details that would let me assess how well it works. There are lots of complex issues with data consistency, but the detailed information on that is years old. Our needs are fairly simple: 2 servers, a shared array, and I'm reasonably sure that we don't use locking. However we'd like failover to work reliably without loss of data.

I have a server running CentOS 5.5 with KVM capabilities. I need to migrate all the VMs to another server with the exact same hardware specs. The problem is it is running on individual harddisks, not shared storage. What is the best way to migrate to minimise downtime?

I'm planning on setting up a home file server. I was wondering what platform would be recommended for something like this. The server would be used mainly for media storage which would be shared between an HTPC and a couple desktops and laptops. I was thinking of just getting whatever motherboard had the most SATA headers on it (which currently seems to be something P55-based) and setting up a RAID5 fakeraid with some 1.5 or 2TB drives and the OS in RAID1 with whatever drives I have laying around. It there anything flawed with this approach? P55 boards with 10 SATA headers are currently upwards of $200, which is kind of pricey. Is there a more economical route that I should consider? Also, are there any known problems with setting up a fakeraid like this using certain motherboard's SATA controllers?

I am going to install Oracle RAC on two Servers, With shared SAN storage (Servers and Storage is IBM) OS = RHEL 5u5 x64 bit
And we used multipathing mechanism and created multipathing devices. i.e. /dev/mapper/mpath1. Then I created raw device /dev/raw/raw1 of this /dev/mapper/mpath1 Block device as per pre-reqs for Oracle Cluster. Every thing looks good, But we faced the performance issue as under.
when we run command :
#dd if=/dev/zero of=/dev/mapper/mpath1 bs=1024 count=1000
the writing rate is approx. 34 MB/s
But If we run command
#dd if=/dev/zero of=/dev/raw/raw1 bs=1024 count=1000
the writing rate is very slow like 253 KB/s

I need a cluster-safe filesystem for a SAN shared storage in Slackware. Red Hat's GFS is the best/only solution?Given GFS support in a custom kernel, what about tools (mkfs,mount...)?

I built a CentOS 5 Linux cluster with GFS storage using local RAID volume and share it with gnbd_export/import on two web-servers. Now I need to expand that storage to another servers local volume. I saw the picture in the manual, but I don`t know, how can I create that scheme.
I can use gnbd_export on the second server and gnbd_import on the first. In that case I will have two volumes on the first storage and I can expand volume group, logical volume, etc on it.

I am working on the beginning of implementing a two-node cluster with shared storage (GFS) and IP address. Both machines are virtual on VMware ESX 3.5, that should not make a difference, but that is the background.current status is that I have a single node cluster built with only the IP address configured within the cluster. The issue that I am having is that I have configured a service to contain only the IP address resource, however, when I go into cluster management that "service" does not register. As such, I cannot bring it online, ping it, etc. below is my cluster.conf configuration:
<?xml version="1.0"?>
<cluster alias="tmbackup" config_version="10" name="tmbackup">
<quorumd device="/dev/sdb1" interval="1" min_score="3" tko="10" votes="3">

I have a PC, with 1 HD of 500GB and the following partitions:
Windows XP - NTFS 50 GB
Windows 7 - NTFS 350 GB
Linux Ubuntu - 98 GB
Linux swap - 2GB
The last OS that I have installed was Windows 7, and each time, when I started up my PC, I saw GRUB first, and after choosing the option to load windows, the Windows loader giving me 2 options, one for Windows 7 and one for Windows XP. I didn't like to see first GRUB and after that the windows loader, it was redundant, but everything was working well. One day, I decided to mix the windows 7 and the windows XP partitions (deleting the windows XP and resizing windows 7). I tried to do that with the Windows 7 utility included in the control panel but I couldn't. It said that I couldn't delete the active partition or something like that. It was not possible to delete the partition in which WinXP was stored.
Then, I decided to boot with Ubuntu and use the partitioning tool that comes with it to delete the WinXP partition. It was possible to delete the partition, and I also putted the option "bootable" on the 350GB Windows 7 partition. After that, I rebooted and it was not possible to load windows. Then I tried changing in GRUB the entry for Windows, because I thought if I could put the correct partition to load from, it wouldn't be more problems. I tried several times but I couldn't load windows, so I putted the Windows 7 DVD and I started the installation process, waiting to see an option saying that there was already a system in the partition of 350GB, and allowing me to fix the mbr in that partition.
My surprise was when I choose the partition of 350GB and the installation process began. I was afraid of to lose my data then I decided to reset the computer! And now, all my 350GB disk is gone! I can't see the partition when I enter with Ubuntu. I'm really worried about this, because the computer detects the 350GB partition as empty, and I don't know what to do! I turned off the computer and now I am using another to write this. I have all my files and important information in that partition! and It seems it's lost. I hope it's still possible to restore the partition. Actually I don't care if I have to install again my operating systems but I need my information!

using onboard windows disk management i have made 75gb unallocated to add to the aforementioned ntfs data partition. but, after resizing extended partition, will i need to fix grub even though i will be adding the unallocated space to a storage partition and not the ubuntu boot partition?

I installed samba and set one of the folders on my desktop to share with my win7pc. However, I'm having some difficulty getting it to work. If anyone can provide some insight, I would be very grateful.
Both my ubuntu-pc and my win7-pc belong to the same workgroup. Each pc can ping the other. The ubuntu-pc can "see" that the win7 pc is part of the network; but it cannot communicate with the win7 pc. The Win7-pc does not show that the ubuntu-pc is part of the network.

I apologize if I'm a little wordy. I'll give the problem, then a detailed list of my setup (to help troubleshoot). Problem: I can't print from Ubuntu 10.4 on my Win7 shared printer. I also can't connect to the Win7 computer sharing the printer (probably a related problem).
Error Message:
1.) I click on Places, Network, Windows Network. I get an error that says "Unable to mount location, Failed to retrieve share list from server."
2.) I click on System, Administration, Printing, Add, Printer, Network Printer, Windows Printer via SAMBA, Browse..., and I get this error "No Print Shares, There were no print shares found. Please check that the Samba service is marked as trusted in your firewall configuration. To do this select System->Administration->Firewall from the main menu."
Network Configuration: I have a wireless/wired network (using a router) where the Ubuntu machine connects wirelessly and the Win7 machine connects wired. The Win7 machine is on a Win7 homegroup and custom named "workgroup". There is a username/password to log into the Win7 Machine. My other Win7 laptop connects just fine to the Win7 desktop's shared printer (and network drives). I know it isn't a issue of it not working (at least with other Win7 machines)
Problem: I'm assuming there is probably a setting in Win7 that needs adjusting (although I've looked at about everything I can find). I also don't know much about Ubuntu so it could very well be something I need to setup in Ubuntu. I checked already to make sure that SAMBA and the smbfs plugin is installed.

I've set up a laptop with Ubuntu 10.04 32bit and shared specific folders on my Win7 PC. Everything should work okay as they both can see each other, but when I try on Ubuntu to access the Win7 shared folder it asks me for username and password. In Win7 I'm always logged in as Administrator with no password set and Ubuntu won't let me connect to it leaving the password blank. It just keeps asking for my username/password over and over again without any kind of error message. It doesn't come up with 'access denied' or anything, it just keeps refreshing the username/password login/connect gui so I can't say which side of the fence the problem is occurring on though I suspect it's on the Ubuntu side.

I dual boot, in the process of installing Windows 7 & Fedora 13 on a new drive. Back in the day when it was risky for the newbie to read/write NTFS, I created a "shared" FAT32 partition. Even though the later Fedoras could read/write NTFS fresh out of the box, I have kept the "shared" partition for my important files (email, documents, digital camera pics).
Now that I'm installing Win7 and Fedora 13 on a new hard drive and I'm partitioning my disk, I'm scratching my head trying to decide how I should format this partition. I was considering the FAT32 again, but I'd like 50GB, not just 32. At the same time, I'm thinking of making the size sacrifice because, and maybe this is just carryover from the olden days and groundless, I have an irrational worry about using NTFS for my most important files.Maybe someone could assuage my fears. Is it just as safe, at this point, for files to be on a NTFS partition and run under Fedora as they are under FAT32?

I've had an annoying couple of days beginning with a win7 reinstall on a dual boot system (win7/10.10) that wiped out grub. I reinstalled ubuntu (10.04) in the hopes of just getting grub2 back up, but that failed and I ended up with a new install of 10.04 on the partition and a happily functioning and coexisting win7/ubuntu wit grub working the way that I wanted.
However, I'm traveling, and tried to reinstall the wifi drivers manually. I think I messed something up and installed the 10.10 drivers onto the 10.04 system (I only had a 10.04 disk and the pendrive usb method failed). Anyway, when I tried to (re)install the drivers from the cd, I got the error: a later driver has already been installed. However, the problem at hand is as follows: now my win7 install doesn't see any of the wireless networks around.So, I think I somehow fraked the wifi card.

I dual boot into Arch Linux and OS X 10.6 on my MacBook pro. I synced my UID between both OSes and created an HFS partition (with no journaling) to use as a shared home/Users partition. For the most part it works just as I'd expect, but sometimes when I'm booted into OS X certain files are "locked" (when I get info on a particular file the "Locked" box is checked under the "General" pane. I can resolve the issue by manually unchecking the box) and/or I get "Operation not permitted" when I try deleting or chmod'ing a file. In both cases I don't see anything out of the ordinary on the permission bits displayed with ls -l, except for a trailing '@' character in the position where the sticky bit would normally occur:
This '@' character shows up on ALL normal files, so doesn't seem to be linked to the locked/operation not permission situation.
On the Linux side of things I never have permission problems. To the best of my limited knowledge and experience with ACLs I've not found any ACLs on any of the files in question.
For what it's worth, I do most of my file editing using emacs (Aquamacs in OSX), is it possible it is setting weird permission bits?
What is the "locked" setting that OS X uses and does it have a permission bit equivalent (so at the very least I could recursively unlock all files in my home directory from the terminal) why might some, but not other files get "locked" when booting into OS X what is the meaning of the '@' character?

I try to set up a 5 nodes cluster and a shared Coraid Storage with conga but it fails with "Shared Storage Support" checked.The message is:'A problem occurred when installing packages: Packages of set "Clustered Storage" are not present in available repository' and it is shown under every node on the next sceen after I submit.The pc where conga runs is on the same subnet (192.168.xxx.xxx) and it has the same /etc/hosts of the other nodes.In that pc runs a proxy too and the nodes go out through it (that pc has 2 NICs)Every node (2.6.18-128.1.14.el5-xen-x86_64) is patched whith the last yum update (this morning) the same is for the pc (2.6.18-128.1.14.el5).Every node has 4 NICs , 2 NICc towards the storage the others in bonding towards the WAN.Every node is exactly alike, they have been installed with the ks.cfg generated from the first node and they all have the support for Clustering, Virtualization, and Clustered Storage.

I formatted a new 2tb drive with XFS filesystem it appears as /dev/sdc on my system and I can mount it ok (I've copied stuff to it and can read and write from it fine)
However when I do fdisk -l it says invalid partition table for this drive only.
I'm assuming I should have created a partition like /dev/sdc1 and then formatted it?
Is there any risk/disadvantage in leaving it as it is - it will hold media files mostly.

I have a fairly large home partition,and several directories with content in, that currently reside in my home account.I now have two slackware installs and would like the content to be available to both installs.Is it OK/advisable to make a directory in /home that has the content in, that both user accounts are mapped to for the content (music and video mainly)? I was thinking of setting the folder as readable/writable by all. This bit makes me wonder if I might encounter problems.There is no spare partition or alternative drive that I could use for this purpose and there is too much data for me to duplicate it in both user accounts.

- I have ubuntu installed, and win7 is installed using vbox.
- I know how to set shared folder, so win7 can access the folder in ubuntu.
- I need to have an access to certain folder in win7 from ubuntu.
How can I do that?It is not about samba, right?

I have a 32g usb stick and I am trying to install Ubuntu on it. But I want to keep 16g as storage space so that I can have it as a normal USB storage for daily use. It's my understanding that I need to create 2 partition ( Since I want to use ext4 for the system which windows doesn't recognize?). But when I created two logical partition and installed ubuntu onto the second partition <sdc6>, I can't seem to boot into there,the screen stays on the white cursor blinking mode, and the usb isn't being read. Is there any way that I could do this? I just want half used as storage and half as Ubuntu system.

My linux system is running from the ram (ramfs/tmpfs). Crated a partition type 'tmpfs'. Processes are reading/ writing from/to this partition files. I am looking for utilities to sync this partition to the remote storage regularly (say, once in 10 sec). Normal copy command will produce partial files, if the copy is getting executed during a write operation.

I have been using fedora 12 for quite some time. When i first installed Fedora on my new system i created 2 ntfs partitions on the hard disk using mkfs.ntfs and in the space at the end of the disk i have Fedora. recently i tried installing Win7 but it didnt recognise the partitions even tho they are NTFS. I had to format 1st partition from setup to install Win7. After boot i find that Win7 doesn't recognise the 2nd partition as welL. The partitions are working fine in Fedora.

I'm using 9.10 on a laptop that has Win7 in another partition. Within Win7 I get strong full bars for the wifi signal strength. On the same laptop in the same location, I get only 2 bars (low) wifi signal strength when I'm in Ubuntu 9.10.
I'm using the wifi transceiver built into my Acer Aspire 5732Z laptop.

So, I just installed Ubuntu 9.10 in a different disk partition than where Windows 7 is currently installed. So, can I just go ahead and format the partition which contains Win7? Won't that compromise Ubuntu's integrity?
