Debian Configuration :: Fastest Partition Scheme Filesystem For Flash Media?

Nov 11, 2010

I thought this might interest someone out there:[URL].. I used SD cards with MBR formatted as ext2 for backup. After I read these articles, I reformatted my cards with GUID Partition Table and ext4 format. Now I make my backup in half the time!

Debian Configuration :: Copying / Moving Root Filesystem To Another Partition?

Mar 4, 2010

My root filesystems flooded so I'm trying to move it to another (bigger) partition but I'm not sure of the best method. I just tried to use "dd if=/dev/sda1 of=/dev/sda6" to copy it but all that did was give me a brand new partition with no freespace available presumably because the filesystem is smaller than the partition. Is it possible to make the filesystem bigger?

Ubuntu :: Fastest Filesystem For SSD?

Mar 19, 2011

I have just got an SSD (Kingston SSDNow 100v 64Gib)It supports TRIM, and is definitely one of the better ones available.I am asserting here that the "limited number of writes" problem is a myth, so I'm not looking for an answer to that.My question is, what filesystem will help me get the best performance out of my SSD? Bear in mind SSDs excel at random access time, but sequential file performance is meh

Debian Configuration :: Lvm Partition - Warning "Unable To Detect Filesystem"

Dec 21, 2010

/dev/sda 74.53gb. Here are two partitions sda1 243.13mib (33.92 used), flags 'boot', and sda2 74.29gb flags 'lvm'. Filesystem for sda1 is ext2, for sda2 'unknown' and it gives a warning "Unable to detect filesystem". At last shut down I also notices red text that said something about logical volumes and lvm.

Hardware :: Fastest FLASH Type For OS

Sep 8, 2010

In the past I've install OS on CompactFlash and USB stick.CF was pretty quick almost as good as HD while USB was much slower.However my new box can boot a 6 in 1 card reader which uses MMC/SD/SDHC/MS/MS Pro/xD can anyone with experience of these formats advise what is the fastest to use for an OS?

Ubuntu Installation :: Add Extended Partition In GUID Partition Scheme?

May 12, 2011

I am not really sure if the title makes any sense or if it even possible. Basically I am currently triple booting with Mac osx on the first partition windows 7 on the second and ubuntu linux on the 3rd with a swap partition. So basically on my 2TB harddrive

Mac (200gb)
Windows (200gb)
Linux (200gb)
Swap (8gb)
NTFS(1592gb)

The last partition is formatted as ntfs using Gparted, windows cannot detect it. The windows disk partitioner shows the swap and ntfs partitions as unformatted. I can unformat the space and use the windows partition to add format it as ntfs but it would format the linux swap partition as well. I am worried that it could potentially screw up everything on my harddrive. My question is. What do I need to do to get the ntfs parition recognized by windows (should I use the windows partitioner)?

General :: Install Windows 7 On Media Partition \ Keep Media Partition Completely Separate From Any OS?

Apr 24, 2010

I just bought a new hard drive so that I could convert my XP-only machine into an XP-Ubuntu-Windows 7 triple boot machine.Since the drive is absurdly huge (1 TB) I wouldn't mind throwing ReactOS into the mixtoo.I just found out that master boot records are limited to 4 entries, meaning 4 primary partitions. I had Windows XP set up on my old drive as a boot partition, a program files partition and a media partition. Since I really didn't want to install XP from scratch, I cloned this setup on my new drive.

This leaves me one MBR partition entry for installing Windows 7, Ubuntu and ReactOS. I'd like to avoid having to install XP from scratch like the plague, partly because it's supposed to be a safety net in case things go wrong with my other OS's and because I've invested a lot of time getting it set up exactly the way I like it.Here are the options I've considered and why I don't like them:Install Windows 7 on my media partition. This would work, but I prefer to keep my media partition completely separate from any OS, so that I can reformat an OS partition without affecting my media partition at all.

Use wubi or something to install Ubuntu in the same partition as something else. Again, this is brittle.Move all my media to a logical drive on an extended partition. Create another logical drive on this extended partition for Ubuntu. The problem here is that extended partitions are rather brittle--if you nuke one, it renders the rest useless.Just put the old drive back in my computer and run XP off it. Use the new one for the other OS's. The problem here is that the old drive is slower and uses extra power, generates extra heat, etc.

Debian :: Flash Drives Auto Mount To Wrong Filesystem

Jun 10, 2011

Sometimes when I plug in a USB flash drive, it is mounted to /dev/usb0 instead of /dev/drivename. This poses a problem for me because I have applications that depend on files I keep on flash drives, and having to frequently change the file paths is difficult. I haven't been able to find anything on this topic with a cursory search on Google or through the Debian reference. Heck, I don't even know what /dev/usb0 is (though I would like to learn, in the interest of being less of a noob). This is happening on a Squeeze system running Gnome, so I believe nautilus is what's responsible for auto-mounting my flash drives.

Beyond that, I don't know what other information I should provide; if you need to know something else, ask me (and perhaps tell me how to access that information). Someone on IRC suggested that I didn't have my drives set to mount in /dev/, but I have no idea how I would go about fixing that. If there's a configuration file that deals with this sort of thing, chances are I haven't touched it since installing this system. Debian installer sees usb drive as cd drive, so it adds it in fstab, but with wrong file system options (udf,iso9660) which is not the one your flash drive uses.

Networking :: Configuration Of A Dual LAN Scheme?

Feb 3, 2011

I have a linux box called worx. Worx has two LAN ports (built in to the mobo). LAN1 (eth0) connects to the network. LAN2 (eth1) connects to MIC, a microscope controller. MIC never accesses the network. I need to be able to use worx to talk to MIC but I don't have my setup correct. The problem I have started via a corrupted filesystem that resulted in a lot of broken packages, including the LAN adapter drivers. I reinstalled the LAN drivers and all the networking utilities. Both adapters can now be used to access the interent if configured with DHCP so there's no issue with the hardware. I need worx to be able to connect to the network on LAN1 and the MIC on LAN2. The MIC is an XP machine that is configured with a static IP (159.159.159.2 in this case). I feel like I should be able to do this myself but for some reason nothing I've tried has worked.

------LAN1 (DHCP) -> internet
-----/
[worx]

------LAN2 (static IP) -> MIC -> microscope

Debian Configuration :: HP Media Bar Not Working

Jul 4, 2011

I would appear that I recently installed linux-image-2.6.32-5-amd64. Since then I have noted that my HP media bar up top doesn't work. This means I can't enable/disable wireless. From an lspci output, it still sees the hardware, and it's loaded, however, not functioning. Should I be looking at rolling the kernel back, or work on getting it working via some other means? Any liveCD I've tried doesn't seem to be able to get it going either. So I'm under the assumption here it is the kernel version, and not a hardware problem.

lspci
00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c)
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) .....

Also tried this to no avail:
sudo apt-get install rfkill
rmmod iwlagn
rfkill block all
rrfkill unblock all
modprobe iwlagn
rfkill unblock all
ifconfig wlan0 up

Ubuntu :: Resize Partition Scheme Lack Of Knowledge The Cause?

Jan 26, 2011

I setup a dual boot system, with approximately 200gig planned for ubuntu 10.10. Based on the article here:[URL]..And this quote:

Quote:

# sda1 Recovery Partition, unchanged
# sda2 Windows partition, shrunk preferably from inside Windows, hopefully about 30Gb
# sda3 Primary Partition, 10Gb, file-system = ext3, in the Partitioning Section of the installer change the "Mount Point" = /

[Code]...

I assumed at that point that the "sda3" "/" would be for booting purposes. I would have to guess that I was wrong, because it is filling up very quickly. As you may be able to tell by the screen shot, "sda5", "/home" was what was assumed to be the file structure to store all of the programs and such.

I have only been running this setup for a week, and would expect to not be seeing my "boot" partition growing so quickly. Do I need to resize it? here do the standard programs that I get from the ubuntu software center install at (partition wise)? I suppose I dont mind wiping that section dry and starting over, but I would give a resize a try if possible.

CentOS 5 :: GPT Partition Scheme On HP ProLiant DL180 Server

May 12, 2011

I'm installing Centos 5.5 on a HP ProLiant DL180 Server with ~8 TB of hard disk (4 disks that have been pre-RAIDED), from an installation DVD.

Normally when I get to the partitions screen, I would select "remove all partitions etc".

But this gives me an error message "Your boot partition is on a disk using the GPT partition scheme but this machine cannot boot using GPT. This can happen if there is not enough space on your drives for the installation."

Pressed OK, tried the other three partition options but they led to the same outcome.

Tried Advanced storage configuration: Showed that there was one hard drive (c0d0) with ~ 8 TB of space.

I figured I should create a root sector, set one up with 100 MB of space, ext3, set the mount point as /.

Created a software raid of the remaining space.

Trying to go "next" gave me a similar error about GPT partition scheme. Trying various other configurations all gave similar errors about the GPT scheme.

What do I need to do? Some earlier hard format of the disk or something?

Debian Configuration :: System Does Filesystem Check On Every Boot After Upgrade

Jul 5, 2015

A few days ago I upgraded my debian sid system, and since then systemd does a filesystem check on every boot which takes over two minutes, disobeying the existing settings I had. How can I set systemd to do a filesystem check only once every a set number of mounts, like I had set up before the upgrade?

Debian Configuration :: Create An Encrypted File And Later Mount It As A Filesystem?

Aug 24, 2010

I am trying to create an encrypted file and later mount it as a filesystem.

KEY=`tr -cd [:graph:] < /dev/urandom | head -c 79`
echo $KEY | openssl aes-256-cbc > container.key
dd if=/dev/urandom of=~/container.img bs=1G count=10
losetup /dev/loop0 ~/container.img

[code]....

The luksOpen command asks me for my passphrase, but always rejects it. I have retried this several times and written down the passphrase - and even tried with a very simple one just to check. And I never can make it work.

Debian Configuration :: Keyboard Layout Used At Boot For Encrypted Filesystem?

Jun 28, 2011

how can I set the keyboard layout used by Debian to enter the password of my encrypted filesystem?

After my recent "aptitude upgrade", I have not been able to mount my encrypted filesystem anymore. I have discovered that the keyboard layout used to enter the password has changed. Problem is that with such layout I can't enter some of the characters composing the password. The encrypted filesystem looks intact, since I have been able to mount it and backup my files by means of a live CD. That means that I can edit any system file, if needed.

Every technique I have found to change layout cannot be employed in this case, since they rely on the system being up and running. I've tried editing /etc/default/keyboard, but that does not work.

Slackware :: Preformatting With Gparted Prior To Installation - Partition Scheme

Jan 13, 2010

A snapshot of my existing partion configuration can be viewed at: [URL] I intend for the space including /dev/sda1,dev/sda2 and /dev/sda3 to be used by slack 13.0. The OS at /dev/sda6 and /dev/sda7 will be "retired" once I get slack up, running and configuration for my work. In the past I have preformatted partitions, that is, from the existing OS, I have formatted partitions for use by the next OS, using gparted. In the case of ubuntu, that has worked well. And frankly, I'm pretty rusty with fdisk....

1)Is there any advantage - or disadvantage - in my doing this for my pending slackware installation? Will slack recognize the "clean" partition and opt to skip formatting?

2)I presume that slack will recognize the existing swap partition. Am I correct?

3)My scheme would be to provide separate partions for /, /home/ and /usr or /usr/local.

4)Any recommendations on filesystems?

Debian Configuration :: Systemd Automounts For Removable Media Not Timing Out

Jul 18, 2015

I have the following hardware setup:

a NAS running Debian that frequently (but not always) has two removable media attached,a Debian desktop that mounts the above NAS via sshfs,the aforementioned removable media are symlinked to the directory on tha NAS that is then mounted by the desktop.

What I'd like this setup to do is to immediately time out if mounts as unavailable. Instead, I only get the expected behaviour if the NAS is down (the ssh client takes about 3 seconds to do that); if it's up, the removable media automounts (they are symlinked to the directory shared with the desktop) seem to never time out, ever. This happens locally on the NAS as well, when ssh'ing to the NAS and trying to run `ls /media/Storage` or `ls /media/Backup`, these commands never return. It's as if systemd was ignoring the x-systemd.device-timeout setting on the NAS.

The relevant part of the NAS's fstab:

Code: Select all/dev/sdb1       /media/Backup   ext4    defaults,noauto,x-systemd.automount,x-systemd.device-timeout=1s,rw,user,nofail,x-systemd.idle-timeout=30s       0       1
/dev/sdc1       /media/Storage  ext4    defaults,noauto,x-systemd.automount,x-systemd.device-timeout=1s,rw,exec,nofail,x-systemd.idle-timeout=5min      0       1

[Code] ....

I find it highly interesting that despite both removable media being detached, only one is flagged as having a dependency failed. Both paths exhibit the hang behaviour, though.

What can I do to actually time out when the media are not there?

Debian Configuration :: Permissions & Fuse - Mount A Remove Filesystem Onto Own Server

Feb 10, 2011

I'm trying to mount a remove filesystem onto my own server. I am able to do this, however I can only access it as root, or if I chmod 777 the lot. Obviously I want to be as secure as possible, so I'd like to avoid either one of those options. Another option is to mount it directly into my home directory, but previously when I was trying out Ubuntu this caused Samba problems - and I was advised mounting in my home dir was a workaround rather than a proper fix.

I have root access with sudo on my own server. I've not set a root pasword, and until I need to I'll avoid it. I have a user account with full control over my own home directory on the remote server. I am mounting using fstab - sshfs#username@remoteserver:/media/sdk/home/username/ /media//remote/ fuse user,idmap=user 0 0

What I would like to do is without changing the permissions on the remote server change the permissions when they are mounted on my own server. I would like them to be in the group sambausers for example. Instead they are owned by root and in the group of 1024 (which I have not set). Additionally for this to work they would have to have 770 on my home server and 700 on the remote server....

Ubuntu / Apple :: Natty Install Changed Partition Scheme (MacbookPro 8,1)?

May 5, 2011

i was experiencing slow start ups since i installed ubuntu 11.04. it took about 20-30sec for the apple logo to come up (or rEFIt). today apple released EFI firmware updates which doesn't seem to install. reason is that the partition scheme is not compatible. EFI Firmware updates only install from GUID partition schemes.
DiskUtility tells me i have MBR. So it seems like Ubuntu changed the Partition Scheme.

Can any body confirm that? how can i make sure ubuntu installs into existing GUID? i will re-partition later today and give you an update if the EFI firmware update installs and boot time is faster.

Debian Configuration :: Bad Superblock On Ext4 Filesystem - Everytime - Computer Powered Off - Clock Resets To 1999

Jan 15, 2010

I added an ext4dev filesystem to my hard drive as /dev/sda3 and mounted at /share with the goal of putting all of my multimedia files on it and sharing it through NFS. I followed this guide: [url]

Of course, this was from lenny (hence the -dev). The partition was fine, and I mounted it numerous times. I also performed a dist-upgrade to squeeze. I shutdown that computer with the usual 'shutdown -h now' and disconnected the AC power cord from it, because I wasn't planning on using that machine for awhile. As far as I could determine, everything was fine before I unplugged it.

Every time that computer is powered off, the clock resets to 1999 because the battery is bad. So I am used to getting the "last mount time is in the future" error.

Three weeks after halting, I powered the computer back on. It was unplugged until this point. I got an error message when it attempted to mount /dev/sda3

I then removed its line from /etc/fstab, rebooted. and tried to check it, but I just keep getting the same error-- even with the '-b 8193' option.

The machine is still using the 2.6.26 kernel from lenny. I am building a new one right now (2.6.30), hoping that the problem is caused by the ext4dev/ext4 module. Otherwise I don't know what to do.
