Debian Configuration :: Multiple Partition Setups Other Than Resistance To Data Loss In Crashes?
Feb 25, 2010
What are the advantages of the multiple partition setups other than resistance to data loss in crashes? Is there any other reason to have a special partition just for your boot directory (kernel files and config) than surviving a major crash?
Also, is it possible to make the Debian installer accept an existing set of partitions? Or even alter the size of the automatically created partitions? Does expert mode let you control the partitions? How many other very detailed things would I have to know to use expert mode, though?

In the process of preupgrading to FC12. Towards the end of the process I get a warning that my /boot partition isn't big enough (12 recommends minimum of 300Mb).
My disks:
[root@fatbeast boot]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_fatbeast-lv_root
35G 6.6G 28G 20% /
/dev/sda1 194M 176M 8.4M 96% /boot
/dev/mapper/vg_fatbeast-LogVol02
29G 25G 3.2G 89% /home
tmpfs 1.9G 676K 1.9G 1% /dev/shm
/dev/sdb 7.5G 319M w7.2G 5% /media/CDF2-6BE2
[root@fatbeast boot]#
Is there a tool I can use to resize my existing partitions WITHOUT data loss? I've been using gparted up to now for sorting partition stuff, does that maintain data when resizing (assuming I run from a boot CD or USB rather than a running system)?

This forum might not be the best place for this question, but some people here are pretty knowledgeable and may have more insight than I do about this. Anyways, I'm thinking about expanding an NTFS (Windows 7) partition on my desktop computer into unallocated space. I know that there is a risk when shrinking a NTFS partition due to fragmentation but are there any risks of data loss from expanding a NTFS partition? My common sense tells me there isn't a risk but I want to be 100% sure I won't lose any files.

I am rebuilding a bunch of servers and want to do it right. They are Dell R200s and R300s with on-board LSI SAS1068E SCSI controllers with 2 SATA drives. The only RAID level supported on these cards is RAID 1. So, to the server, we have 148GB of space to deal with. They currently run 32-bit Ubuntu 8.10; I will be installing x64 Ubuntu 10.04.
I have always seen that it is best practice to partition in such a way that /boot, /var/log, /temp, and /home for example are separated out from /. Usually this is on a RAID5 or higher box. Is there any benefit to doing that sort of thing on a RAID1 box? I realize that this is in some ways a matter of opinion, but I would like the opinion of folks with experience. I'm pretty new to Linux in general.
The main services running on these boxes are Apache2, Tomcat6, MySQL, and Java.

I'm running 10.04 X86_64. I have this 650 GB External Hard Drive With three partitions: one fat32 and two ext4. Sometimes when I plug the drive in X crashes. I get no response at all from the keyboard but the pointer works. I am able to minimize and maximize windows but i cant close them and i cant click on the top bar. Today the error occurred after I transfered some files from one of the ext4 partitions to a 320 GB External HD(single partition FAT32). I pressed the ctrl + alt+ f1 ( to go to the shell :-/) and this strange lines of code where showing up over and over again:
[XXXXX.XXXXXX] ata1.00:status: {DRDY ERR}
Also the following exception:
[XXXXX.XXXXXX] ata1.00:status: Exception Emask 0x00 SAct 0x0 SErr 0x0 action 0x0
When i came back to X (ctrl + alt + f7) and unmounted the drives every worked fine.

I'm planning my next desktop build (currently only have a laptop that is falling apart), and one of the features I'm really looking forward to is multiple monitors. I'm thinking a 1920x1200 center monitor and two 1600x1200 on either side, but I'm not decided just yet. I don't know if I really need that resolution.
I have a few specific questions though. The only time I've ever messed with multiple monitors is way back when I had Windows, so I'm not sure what to expect on Ubuntu.
1: What is the best Graphics card brand/series to use? I've seen that ATI has more powerful hardware than nVidia for the same price range, but nVidia seems to support Linux better. I'm using an ATI card in my laptop now and have never had any problems with it (with either open source or proprietary drives, other than open source drivers didn't do well with 3d). I would also like these GPUs to be running F@H while I'm away, so GFLOPS is just important as gaming performance.
2: Since I want to use 3 monitors, I assume I should get 3 of the same graphics card or a card with 3 identical outputs (do those exist?).
Or can this be done some other way. For example, a more powerful card for the center monitor, and less powerful cards for the other two. Do those need to be the same brand, or could I use, for example, ATI and nVidia cards on the same desktop simultaneously?
3: Is it possible to have a virtual console on one monitor with a desktop on the other two, or do I need to set up a terminal on the desktop to use that monitor?
4: How can I run fullscreen SDL games with multiple monitors? Will it only show on one screen or stretch across them all? Is it possible to have a fullscreen game running on one monitor with the desktop visible on the others? How would the mouse focus work with that? Or does it just all depend on how I setup the monitors?

I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?
Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?

I installed Ubuntu 10.04 on the laptop and it looks pretty good. I currently run 9.10 on the main desktop and would like to upgrade to 10.04, by pressing "upgrade" in the update manager, but I have some questions before I do, namely about data loss.
If I upgrade, will stuff like Thunderbird keep my emails, FF keep its profile (cookies, bookmarks, addons etc..), the documents keep all the documents, I have an apache server installed with a few websites - will they still be there after an upgrade? I also have a virtual machine with windoze on, what about all the stuff in there and VMware itself?
Or, will I need to back everything up onto an external hard drive (not sure how to backup Thunderbird and FF), and then reinstall everything, and transfer all the documents, websites etc.. back over again??

I have a laptop running slackware-current. The disk is /dev/sda and the root 'sda1' is xfs formatted (there is also linux swap at sda2).
recently I was trying to setup openvpn and had to copy a folder with configuration files from /usr/doc/openvpn_<version>/easy-rsa to /etc/openvpn.
I am sure the copying completed cause I got a prompt, but a few seconds later the battery died on me. When I got mains and powered it up, I could see the directory I copied under /etc/openvpn, and the files where all there too. but they all contained nothing. i.e. they had a size of 0.
I read [URL] Fthat an external journal filesystem for root is not supported. I am not sure If it applies to my situation though. As in does it use an internal journal instead?
and the bottom line is: shouldn't the copying have completed successfully? shouldn't I be worried, that this copy failed?

I am trying to start OpenOffice Base (3.2.0) but it keeps crashing once I begin to edit a new data base. Calc, Writer and Impress work fine.
ramack@ramack2:~$ soffice -base
ramack@ramack2:~$ libgcj failure: gcj linkage error.
Incorrect library ABI version detected. Aborting.
I haven't a clue as to how to fix this one. A web search finds a Debian bug that a couple years+ old. The bug has since been resolved. It crashes if run as root too

I have a 1TB External HD that at the time of purchasing was used with my PS3 which only allowed FAT32 HDs. But now I am using it for other uses. I have came across the problem of the file size limit of 4gb that FAT32 has.The problem is I have about 200 GB filled of data on this HDD and wish to convert it to NTFS with no data being lossed. Is this possible and if so how?

I have installed installed Debian 9 (stretch/unstable) which has GNOME 3.16.3 and runs Linux kernel 4.1.0-2 by default in Virtualbox 5.0. The host OS is Windows 8.1 On each instance of activating full screen mode in the VM, a freeze occurs then an abrupt close (abort).
I am inclined to believe that this problem resides in the OS (Debian 9) rather than Virtualbox or the Host. The reason being is that prior to installing Debian 9 (today) I had Jessie installed for quite some time where this error/issue never surfaced.
This issue is rather complicated in the sense that if alternating between full screen and normal mode quickly, this occurs whereas, if done every 10 seconds or thereabout it happens almost seamlessly. Also, if 3DAcceleration is switched off that doesn't occur.
How do I find the root of this problem and a resolution to it?

A recent update to Iceweasel 5 (version 5.0-6 ) on my debian (Linux xxxxx 3.0.0-1-amd64 #1 SMP Sun Jul 24 02:24:44 UTC 2011 x86_64 GNU/Linux) led to a rather odd an annoying behavior. Each time I try to open an external file (pdf, odt) or to save a file on the hard drive, then Iceweasel crashes systematically. Does anyone experience the same? Any idea of how to fix this?

This problem is not exclusive to Ubuntu, I've experienced it in Windows and OSX as well, but it seems that almost every time I transfer a large number of files (i.e. my music collection) between my desktop computer and laptop via my external hard drive, I end up losing files for no reason. I usually don't notice the files are missing until later on, because I am never informed of any data loss. Now, every time I make a large transfer of files, I just do it two or three times to ensure that I don't lose any files.

Last time I installed Ubuntu in a dualboot configuration with Win7 on one of my machines, my entire boot sector and Windows install got corrupted, resulting in a complete loss of all my data and requiring a fresh install of Windows.
I looked into this a bit after the fact, and it seemed to me it was due to conflicting hard disk geometry between Linux and Windows.
My question is, how likely is this to happen with Fedora? Is this because of Ubuntu? A bad install? Is there someway I can avoid this from happening when I install Fedora if it will happen?

I have 2 external drives that I'm using for movies and they're both formatted to fat32. The problem I'm experiencing now is that some of the high quality mkv files are not able to be moved to the drive because of fat32's limitations.
I'd like to convert to ext3 (or 4) and I wanted to check to see if I can do it without having to reformat and without loss of data.

I have a Debian server that had only one onboard NIC (1000 Gbps) but now I've added two PCI Intel Pro 1000 NIC's into the system to bump up the total # of NIC's to three. My question now is can I specifically assign or force Debian which interface to configure as ethx? I would always like my onboard NIC to be 'eth0' and the two additional NIC's to be 'eth1' and 'eth2'. For some reason Debian loads the modules at random and sometimes what was my

I'm renting a server which comes with 5 IP addresses, but only one network device. From what I can understand I'm able to create aliases by adding entries to /etc/networks/interfaces, I haven't tried I'm in the planning stages. Hypothetically, 192.168.22.30 is my primary IP and I want to set eth0:1 to have 192.168.22.31, and then after that I want to create a virtual machine (using kvm/qemu) that is able to communicate bidirectionally to the internet over eth0:1, and leave eth0 strictly for administrating (not for VM traffic).
The qemu guides I'm finding seem to assume that I want to use TAP or VDE, what I want to use is a sub-ip/alias. One guide I saw had me eliminate everything from eth0 and put it under br0. That would leave me unable to ssh into my server (and unable to administrate). Is there a way I can do something along the lines of: qemu [options] -net [option] -netdev=eth0:1 ?

I'm trying to setup a DHCP server that serves several different VLANs, we have 5 in total. Our network is working correctly, with static IPs, we're able to ping across without any issues.
When I connect my debian box to an interface on VLAN5, statically assign an address in the correct range, it works. Similarly with all other VLANs.
To configure this box as a DHCP, I set one of the ports on the switch as trunk, connect that to the debian box to allow all VLAN traffic to reach my debian box.
I setup DHCP following the steps on [URL] ....
Then I configured different VLANs by following the steps on [URL] .....
However, with the vlans setup, I am unable to ping anything. This is essentially what I did.
Code: Select allSet the port on the switch to trunk with 802.1 encapsulation
disable eth0
vconfig add eth0 5 # to add vlan 5
ifconfig eth0.5 192.168.5.254 netmask 255.255.255.0 up
vconfig add eth0 5 # to add vlan 10
ifconfig eth0.5 192.168.10.254 netmask 255.255.255.0 up
[Code] ....
I do not know why I am unable to get any connectivity through my VLAN interfaces.
