I'm working on a server and noticed that the to RAID5 setup is showing 4 Raid devices but only 3 Total devices. It's on a fully updated CentOS 5 system that only has three SATA drives, as it can not hold anymore. I've done some researching but am unable to remove the fourth device, which is listed as removed. The full output of `mdadm -D /dev/md2` can be see below. I've never run into this situation before.Anyone have any pointers on how I can reduced the Raid Devices from 4 to 3? I have tried
I'm running Lubuntu 10.04 on a Thinkpad T41. I had been running for a week before realizing that my USB devices (card reader and thumb drive) were not being recognized. I thought that the issue might be related to my aging Thinkpad but I installed the hard driveat is running Slackware and I had no issues with USB devices. I reinserted the hard drive with Lubuntu and was unable to recognize any USB devices.Has anyone else noticed this issue? If so, is there a fix for this issue?
For some reason my USB devices just stopped working. I'm on my laptop, so I really don't need a USB Mouse but I like to use it. I also can't use my flash drive. The Command lsusb sees it. It will see both the mouse and my flash drive. I don't have any other devices to test, but I would like to know that they would work when I need them. The strange thing is it also used to work. I don't know what changed.
I can't access my USB devices via Computer, yet I can generate a list with: Code: lsusb Output: Code: Bus 002 Device 004: ID 05a4:9866 Ortek Technology, Inc.

usb devices inserted after bootup aren't being automounted and opened. For the life of me, after much googling, I can't get them to work. the ehci_hcd, uhci_hcd and ohci_hcd modules are not loaded, but those were from some old posts, and I don't know how relevant they are to me.But if I insert the usb before startup, ubuntu now recognises and automounts any usb device.before the recent kernel update ( **.2 my wifi dongle would be recognised. but after,it seems as it too isn't being recognised.for the meantime, I am keeping a small unused usb device plugged in the back of the tower.
When copying files to USB storage of any sort, Nautilus has started hanging after a few files (varies from 1-200 files and a few MB to over 5GB on various occasions), failing to unmount the device, and eventually throwing up an I/O error and freezing.
If I kill/restart Nautilus and reconnect the device it can still be read but comes up as read-only. I can't copy files to the device again, and attempts to erase and reformat it fail in both Ubuntu and Vista. Oddly enough XP will reformat the device, after which it works properly again.
Please help! I could deal when it happened to my USB key but I just bollocked my mate's portable drive and he's a bit pissed off Seems to be happening on all my USB ports.
I am just getting started with Ubuntu and love it so far. It has breathed new life into an old Compaq Presario V2000 and once I get up to speed on it I hope to start running it on all the rest of our machines.
The only major problem I am having is that none of the USB devices I have plugged in are being detected. From what I have seen online I should be getting a notification and should be able to view the devices at Places/Computer but so far, nothing. Googling this problem it appears that individual devices often don't work but I could not find anything on all USB devices not working.
Jaunty is fully updated but SUDDENLY is not recognizing external devices (card reader, camera, DVD inserted in drawer, etc.) In other words, I cannot see my media and, therefore, cannot open it.
Anybody else having problems here? What's up? Did something go wrong in the updates?
I have a usb bluetooth dongle I've connected to my machine. The device appears just fine and using hcitool scan I can scan for device with no trouble. However blueman doesn't seem to register the device even when I force the applet to display and try add a new device it won't scan/see any of the bluetooth devices. Has anyone come across something similar or would know how I should proceed?
I have just installed 10.04 as an upgrade from 9.10.
I am having difficulty because none of the USB drives I am using are unmounting as they should be. normally speaking when erasing data from my USB key when you come to unmounting it it will ask if you would like to send this data to the recycle bin thus giving you back the extra storage space on the device. 10.04 isnt allowing me to send these items to the recycle bin ad doesn't give the option to do this.
i've been having this problem since lucid, in both ubuntu and kubuntu, though im currently running kubuntu wich is why i tagged it that way.I open k3b, and it immediately tells me there's no optical device/drive...Then i "wodim --devices" and it returns
Code: wodim: Overview of accessible drives (0 found) : well that sucks, next stop "wodim --scanbus"
I currently own an easyCAP, standard definition capture device. I'm looking into purchasing a HD capture device, but the only one which says it supports Linux in the spec is the Blackmagic Intensity Pro (PCi Card). Here is a list of the ones which I'm looking into possibly getting, but I'd like to know if I can use it to record (my Xbox 360) on Ubuntu (Studio) 10.04 Lucid Lynx, and how hard it would be to set it up. Blackmagic Intensity Pro
Hauppauge HD PVR AVerTV HD DVR Blitzbox HD
Also, if you know of any other decent HD capture devices, comment and let me know
I just bought a Nokia N900 and it's a beautiful device!
Naturally, since it runs Linux, it's unable to synchronize with other Linux devices. It's one of those wacky universal constants you can't seem to understand.
I've tried using SyncEvolution, which supports funambol, but it does not work. It keeps complaining about a failed authentication or whatnot.
basic script on unmounting devices, as that option was removed in Ubuntu Lucid?I'm aware I can possibly recompile the nautilus source and all that, but I think a much easier method would be to just add a script for such. Something basic, like this, but that includes ALL devices that can be unmounted (such as flash drives, external hard drive, and sd/xd cards), not just disc drives. Pretty much what the right click 'Unmount' option in nautilus used to be like:
Was just wondering if it was safe to run devices off of an unpowered USB-hub, unfortunately I do audio production and when the DC-adapter is connected I get horrible alternating hissing noises through the sound system. Was just wondering if it would be safe to connect an external mouse, keyboard and a self-powered printer to the usb-hub without drawing too much current and wrecking the system.
My friend bought a new PC, and he's duel booting Ubuntu 10.04LTS and Windows 7 Ultimate. At first I tried partitioning the hardrive using fdisk in Ubuntu, but it couldn't find hda. After looking in /dev/, there wasn't hda, or any sd* devices. I looked in gparted and used the installer afterwards and both came up with nil. I installed Windows, updated the BIOS using the utility that came with the mobo, and tried seeing if Ubuntu could detect my hardrive and it couldn't. I even turned ACPI off when booting and that didn't work either.
The motherboard is a new Gigabit with 3 PCIe slots and a USB3.0.
I'm looking for some help on how to troubleshoot the network on Ubuntu 10.04 64 Desktop. It's on a Acer Aspire 721. There's a wireless card but the widget in the top right says there is no network device.
I just attempted to purge and reinstall ALSA (and all of it's related packages/utils) after disabling the on-board sound in an effort to use only an M-Audio Delta 1010 as the sole sound device. I've also tried to reinstall Envy24, as well as drivers for the ICE1712 chip... Now,I have no sound devices. alsamixer tells me there is such file or directory. When I go to /proc there isn't even an asoundrc file there.
I don't know what to do. I've spent the last 4 hours looking for a fix, and trying all sorts of things, even the comprehensive sound troubleshooting guide on this forum. Nothing. I got absolutely nothing. Everything goes exactly as the guide states, except after rebooting, and trying aplay -l and alsamixer, it says there's nothing installed?I have to have a sound, this machine is a DAW .End result I'm looking for is to use the Delta 1010 as the ONLY sound device.
After reformatting a usb drive with gparted, no usb stick will automount when I plug it in anymore. If the usb is in place at startup, however, it is recognized and mounted.The media will show up in fdisk and disk utility, but there is no link to it in Places > Computer. I have no trouble manually mounting, but I would rather not have to go through the hassle each time I plug in my flash stick. I am running Ubuntu 10.10 64bit
Just built a box and once 10.04.2 64 bit was all installed and loaded up I realized instead of showing my Ethernet as connected it had the ol x. So when I clicked on it I got "No network devices available." The mainboard is an Asrock 890GX Pro3, link light completely out.
After installing Ubuntu 10.4, and rebooting, my cd/dvd and usb memory drives did not operate. An example of this problem is as follows: Upon inserting a cd or flash drive into my machine it would attempt to read the device but would fail. It would not display an icon on the desktop for either device. Upon opening Places>Computer the device would be displayed there. If either device were selected, and an attempt made to open it, the machine make another attempt to open and fail again.Ubuntu 10.4 was a clean install. I then did a clean install of Ubuntu 9.10 with all updates and everything worked fine, then upgraded to Ubuntu 10.04 with the same results.
I have an Acer Aspire 3500 laptop that I'm running 10.04 on, pretty much everything works OK, and I don't appear to have any hardware problems (I've checked using Gnome Device Manager). When I plug in a USB flash or hard drive, I don't get any drives/devices to mount, although in Gnome Device Manager the USB device appears as a USB Mass Storage Device.
Running tail -f /var/log/messages produces this:

I'm trying to detect an external HDD drive, but I don't know how. My PC has a total of 6 USB ports, they're all being used, and the Computer File Browser lists only 4 USB ports and I can't open them.The ports could be detected in Windows Vista, except I've not tried the new HDD enclosure, but it crashed.
I have two identical hard drives; same make, same manufacturer, same model, and same capacity, which I'm trying to run in a RAID1 mirroring scheme. The problem: configuration files for md arrays only lets me use device names, such as /dev/sdb and /dev/sdc. To keep these the same (and in the same order) when I boot I wanted to write a udev rule for them. Unfortunately, I have no way to differentiate between these two drives, as they seem to be identical. Normal methods of differentiating by size or model name wont work. I think I can use UUIDs; but I neither know how to get the UUID of a device/partition, nor do I know how to use it (if it is possible) in a udev rule.
Solution:
run udevadm info --query=all --path=/sys/block/sdb # or whatever block dev
Look for and use "ID_SERIAL_SHORT" which is unique even for identically manufactured disks. Write a udev rule based on this property.
Since I created second user USB devices as PTP camera, flash mass storage automounts always for the new user. Even the second user is not logged in automount does not work for main user. When I log in as second user (with device plugged in) it is mounted automatically after log in.
What can I do with this problem? I would like to access devices from each user (not necessarily at the same time). How can I configure it? How can I "remount" device to my current user without switching into the second one (it's someones else account)?
My bluetooth devices disconnect after a period of inactivity (not sure exactly how long). They're being connected with: sudo hidd --connect And I've made no edits to any bluetooth related system files so it should be default settings throughout. I would like them to stay connected indefinitely and it would be even better if they would stay connected through reboots.
