I decided to have my laptop with dual boot. Already having Win7, I tried installing Ubuntu on another partition. While installation was in progress, during the step where we manually choose partitions to install ubuntu on, I was asked to provide a swap area for ease of operation. I provided another active partition for this supposing that this "swap area" is needed only during the installation. Unfortunately, as I found out later that this makes that important active partition to be unavailable to work upon both in windows as well as Ubuntu. I need to use this partition again.
I tried the "disc utility" in System--->Administration section to change the partition type to "hpfs/ntfs". After a longtime it showed me error (Unable to perform the operation). What could have gone wrong? I absolutely need that drive back, as it contains valuable media files.
This thread is not so much looking for a 'solution' as it is looking for some 'reason why', as I now have it working.I have just inherited a Gateway 509GE - P4 3.0GHZ / 1GB RAM / 200GB SATA WD2000JD HD. It is circa 2005 hardware. The previous owner had tried to install Mandriva after windows began to choke on accumulated garbage, then tried to revert to XP, both of which appeared to install but neither would boot. He decided to just get a new box and gave me this one.I ran Memtest86 and found a bad DIMM and replaced it.
I repartitioned and formatted, a single ext4 root partition plus 2GB for swap. I completely removed existing partitions including the hidden M$ restore partition and checked disk - all using Gparted Live CD.I put a full Slackware 13 on it, installed with LILO to MBR, rebooted... nothing... "No bootable device found".I booted to install CD and played with Gparted Live CD and everything was there and LILO configured correctly...I tried several times and looked at MBR sector directly - all OK as far as I could tell.
Long story short - as far as I can tell after trying a few things, I finally set the 'active' flag on the extended partition (sda1) and it now boots.But Linux does not care whether a partition is active and I have several boxes - including another with SATA drive that do not have any 'active' partitions. So I conclude this must be a BIOS thing looking for an active partition, but see nothing settable in the BIOS config (in fact very little useful in this machine's BIOS config).Anyway, it is now working but I would like to solicit any useful comments from others. Is it a Gateway thing? (This is my only Gateway box). Is it an SATA thing? Anyone else had to set a Linux partition active to boot
I recently installed Debian 7.6 64-bit on Dell Vostro 1520 laptop.Using Gparted, create extended partition in the remaining disk space 67.91 GB
Install Debian 7.6 as follows
Code: Select all/dev/sdb5 / 8GB Ext4
/dev/sdb6 / home 17GB Ext4
/dev/sdb7 swap 5GB
I opened a terminal and ran some commands to show the results below....
Code: Select allroot@DELL-DEBIAN:/home/hugh# cat /proc/swaps
Filename Type Size Used Priority
/dev/sda7 partition 4979708 0 -1
root@DELL-DEBIAN:/home/hugh#
Code: Select allroot@DELL-DEBIAN:/home/hugh# cat /etc/fstab
# /etc/fstab: static file system information.
[code]...
I have a couple of questions....
1. Does the data above indicate everything is running as it should?
2. What does this command tell me about swap? "/sbin/swapoff /dev/sda7" I read somewhere it should be run on 64-bit system but not sure what it does.
3. Is the command "cat /proc/swaps" the best way to determine if swap is running ok?
4. Can I share this swap partition with another distro, e.g. Ubuntu or Xubuntu? as I would like to multi-boot for testing purposes.
There's something very annoying about how Nautilus opens "image viewer" windows.
They open, I can see them, but when I press the keyboard, it's still Nautilus which gets the commands.
This is because Nautilus stays the active window!
Most annoyingly, when I want to have a quick look at an image, and then close it, Nautilus closes instead (Alt+F4).
Does anyone know what I'm talking about?
How to solve it?
I followed these steps to add a client to my active directory domain, everything is working as expected except that when a username has whitespace it creates a directory in /home with whitespace and gconf fail to access his config dir in the user's home. KDE also fails to start but I don't know what's failing yet. I found that the easiest way to fix these issues is to replace whitespaces by underline in homepaths so I changed the pam_mkhomedir source to replace the whitespaces and save it using the usermod command. It should work but is not... the reason is that I can't change the user data using the usermod because domain users are not in /etc/passwd.

View 2 Replies View RelatedA few days ago my Laptop wouldn't hibernate in Windows 7, I managed to fix this problem by going into Windows' Disk Management tool and setting the C:/ Partition as the active partition, this fixed my hibernation issue, however I have just noticed that now when I boot my laptop my GRUB menu no longer appears, instead it just loads Windows straight away as if it was the only OS on my laptop.
I've confirmed it's something to do with my recent Disk Management change as I booted up GParted, removed the boot flag from Windows and when a rebooted my GRUB menu reappeared.
Not sure on how I can both have Windows as the active partition while being able to keep GRUB working also.
My Partition Setup is as follows:
/dev/sda1 C:/ Windows 7 (NTFS) (Boot Flag Set)
/dev/sda2 D:/ DATA (Documents and stuff) (NTFS)
Unallocated 1 MB
/dev/sda3 Extended 146.49 GB (LBA Flag Set)
/dev/sda5 Linux Swap 2.01 GB
/dev/sda6 ext4 20.00 GB
/dev/sda7 ext4 124.46 GB
Unallocated 10.00 MB

Is there any way to make a disk image of an active partition? I have to get a complete backup (partitions, MBR, all data files) of my server without bringing it down to do it. I want to have a backup that, in the event of a system failure of any sort, I can quickly restore onto a new, bare hard disk and have the system back up and running. The windows equivalent of this would be something like Drive Image XML, this is the functionality I am looking for.

I have desktop effects on and window shadows enabled. The main windows don't seem to follow this, nor does any taskbar pop-ups when you hover your mouse over them. I even set the shadow settings to high/annoying settings but I only see it on context/right-click menus.
I don't like the blue shadow because it is too light, but I can't seem to find where to change it. This seems to also apply to in-active windows as far as the size of the shadow but with a gray shadow instead. Still, if the desktop effects were effecting this, then the shadows I see should be large. Plus, desktop effects only give you one color choice with it just being darker on the active window. How to change this?
I'm convinced that mdadm is going to be the death of me. I've wasted numerous hours on this so far without luck.
OpenSuse 11.4 on an old Supermicro box, creating a software RAID1 array across 2 x IDE 500GB disks. Creating /dev/md0 as a 250MB partition across /dev/sda1 and /dev/sdd1 for /boot, another 465GB partition across /dev/sda2 and /dev/sdd2 as an LVM partition to hold volumes for the various other OS filesystems. After the initial installation and configuration there were a series of mishaps with faulty IDE cables that had drives failing to show up at boot. Somehow, /dev/sdd2 got configured to array /dev/md1 as a spare drive. And nothing I've done so far gets it to show up as an active drive.
The obvious step of failing the partition, removing it, then adding (or re-adding) will bring it back as a spare. I've tried roughly a dozen different permutations of those same steps. The latest was to 'dd if=/dev/zero of=/dev/sdd2' to clear the partition. Thought this might be the trick - after the zero, mdadm -E /dev/sdd2 reported 'no superblock' and no md1 configuration.
So 'mdadm --add /dev/md1 /dev/sdd2' and it still comes back as a spare. Here is mdadm -D /dev/md1
/dev/md1:
Version : 1.0
Creation Time : Sat Jul 9 10:26:01 2011
Raid Level : raid1
Array Size : 488119160 (465.51 GiB 499.83 GB)
code....
I can't stop this array, the OS is running from there. I can't easily boot from CD to repair, all IDE ports have disks attached.
Does anyone have an incantation to promote a spare to active?
how to setup an Active/Active Load Balanced and High Available (If one of the nodes is down the system still runs) MySQL cluster. I have found quite a few howto's but I have some things unclear in my mind. I found a few solutions like this one: [URL] or this: [URK] Those are using two or four MySQL nodes, two Load Balancers to avoid a single point of failure but only one MySQL cluster management server. What happens if the MySQL cluster management fails?
I have also found a "MySQL Master-Master Circular Replication" technique but from what I read, with this option there is a chance that conflicts will arise if node A and node B both insert an auto-incrementing key on the same table.

this error:impossibile salvare le proprieta' , non hai accesso sufficiente per scrivere su /dati/eros/.directory tha in english is something like this: impossoble save properties, you havent enough permission access to write on /dati/eros/.directory this happen also as superuser I remember that with suse 11.0 or 10.3 I was able to change icons on fat32 partitions, now with 11.3 I cannot, there ought to be a way to do what I did with the previous version with this 11.3 brand new ad more advanced version shouldn't it?
I am relatively new to Linux and Opensuse. I created the / root partition and now it is growing and maxing out. I have partitioner available to me but how do I change the partition size when the root partition is mounted. Do I login as root and then umount or modify fstab and restart and change from command line or do I format and reinstall everything? I have room to expand but not sure how to manage this?

If its possible (i dont see why not) to extract the ubuntu livecd iso onto a small partition, with the purpose of booting that partition via an additional grub entry configured to do so?
Im thinking of this much like a 'recovery' partition some systems are shipped with. where if somthing went wrong, (as long as its not a misconfiguration in which grub wont load...crap..thats not uncommon.. lol) it could be fixed using that partition instead of reinstalling the iso onto my USB flash drive whenever this happens.

View 1 Replies View RelatedI had occasion to boot Ubuntu livecd yesterday on a Dell machine with XP installed. I pressed the Escape key during boot to see what might be happening behind the Graphic ...... and got a rather upsetting surprise ..... ... apparently Ubuntu was reading and writing to the XP partition ..... without any notification to me. I don't have the exact wording to hand, but what is said was that the XP install was 'dirty' and it was fixing it .... fixed! I used a 9.10 CD. Is there any information out there that addresses this behaviour? Is there a way to boot the CD and prevent this from happening? I do not expect or want ANY liveCD to write to ANY partition on ANY PC I might boot using that liveCD without my explicit permission/instruction. That this liveCD did write to a partition without asking or informing me is sufficient cause for me never to use such a liveCD again.
