I need to auto-mount a storage device AND execute a program passing mount point path to it. How can i do this? I'd like to avoid polling for new storage devices. I'm looking for something like acpid for ACPI events, but working with storage plug events instead.
View 6 RepliesI plug a USB device, it gets a /dev entry, e.g. sdf, i mount its filesystem, then some program opens a file on this filesystem. I unplug this device, its /dev entry disappears, but if i replug this device again, it gets another name - sdg.
How can i force the program to close the file so the filesystem is ready to be unmounted without using "lazy unmount" to release the device name, BUT so that the program doesn't crash after trying to make I/O to this file, and, of course, without having to kill the program?
I just installed TuxGuitar - very cool - and to get the sound to work I had to install Timidity++ as well. Before I start TuxGuitar I have to execute:timidity -iA -Osin a terminal window first, which is kind of a pain to do every time I run TuxGuitar.How do I get this line to execute on startup such that timidity is running when I start up? I tried adding that line to rc.local

I would like to exec a script whenever a user mount a device. The device could be an internal device (for example a partition on a second hard disk) or a removable one (for example a usb hard disk). The script must have sudo capabilities even if the user is not included in the admin group. Is it possible?

View 4 Replies View RelatedI want to use a USB "stick" or "pen drive" or whatever you call it to carry files elsewhere.
Nothing appears in "places" after I plug it in.
I am comfortable with the shell. That is not a problem. In Fedora 6, it would appear in /dev/mount or something--I forgot. With Fedora 10, I have no idea where to look.
I've bought this remote control that sais it works in Vista, XP etc. without any driver. Basically it has a bunch of buttons that replace the mouse and a bunch of others that replace basic keyboard functions (arrows, enter, escape). It has a USB IR receiver so I thought I could simply use it as a lirc remote in Ubuntu.
However, it sais absolutely nothing on it except for "PCremote" so during lirc installation I have no idea what to choose. And, interestingly, I accidentally discovered that it works in Ubuntu, too, out of the box. Controlling the mouse and acting like a keyboard. Is there a way I can forfeit current functionality and just get it to work as a customizable lirc remote? Or even better, keep current functionality but change it only for certain apps (xbmc, vlc etc)?
is there a way or terminal command to disable access to a USB storage device upon insertion given that it is not permitted?

When I shut of the usb mass storage on the samsung R450 it switches to modem and is properly detected and usable as modem by my system.I don't have any other problems with other usb devices, such as a digital camera or flash drives, so I don't know if I just missing a system setting or configuring something wrong.
I just discovered that inserting any USB drive causes an immediate hang of the system. The keyboard caps lock and scroll lock lights blink. Only recourse is to power cycle the system. This is after installing Kubuntu 9.10 in January, I don't believe I had occasion to insert a USB drive until tonight. 100% reliable. No entries in logs, presumably because it hangs the kernel when it happens. The /var/log/kern.log file has been corrupted due to file system damage (1+ sectors of some other file inserted into chain) and probably other files as well.
I've not had occasion to report other bugs, but I've found no way to report anything other than application bugs. I tried using "ubuntu-bug kernel" which helpfully said there was no such application as 'kernel' and has been busy "collecting problem information" for the last half hour or more. Somehow I don't think its ever going to finish.
The crash only happens when booted into Kubuntu 9.10. If I boot off of 9.04 then USB drives work fine. Both USB drives I've tried reliably produce the crash. One is a random cheap USB thumb drive (imprinted "Cisco"), the other is a 16GB Corsair Voyager.
I had troubles with my NTFS external hdd mounting without becoming root until I changed my fstab file. However after changing my fstab file I created an error in the place of the one I had fixed.

* I am implementing mass storage device on a test board.
* It contains NAND flash.
* Using corresponding "udc driver" and "g_file_storage" I could make my test board enumerate as mass storage device on my Linux machine.
* my 16 MB pen drive (test board) is now ready for read/write.
But there are some Bad Blocks on the NAND.Hence copy is not complete. Although on Linux machine there is no error message. Now , what is there in a normal pen drive which manages the Bad Block or what am I missing so that such Bad Blocks are managed.
Here is the error I get on my test board :

I am running Fedora 12 OS on my machine. I would like to disable the USB devices for normal users so that usb-storage devices cannot be plugged in. However at the same time a mouse or a keypad may/could have a usb connection. note that root should be able to use the usb storage devices. How can the same be done on fedora 12? I would prefer not to do it via the BIOS options.

Whenever the laptop is connected to my personal router everything goes through it and it can't connect to any external web sites. But when I unplug it and go only on my family's wireless everything is fine, except I can't connect to the storage device since it has no external connections.

Since I use openbox with some packages from Xfce4 (mainly for convenience) I get most stuff "for free" as it were when using openbox, but I can't figure out how to mount android devices in a simple way. I can either do it manually, or install some other file manager that has this capability. This leads me to my question, I've noticed that if I install Nautilus, which automatically mounts android devices OotB, I get this functionality in Thunar as well. This leads me to believe that there is clearly a dependency package of some kind installed when running apt-get install nautilus that enables it, It'd be great to get this functionality in Thunar without having all the nautilus packages just littering about for no good reason. the required package is gvfs-backends, which I should have realized when I was unable to browse smb:// addresses. You forget a lot when you only make a fresh install once every 2 years or so.

I have NIS and autofs working -- mostly.The home directories reside on an EMC network storage device.

I've searched high and low, and can't figure this one out. I have a older Olympus Camera (2001 or so). When I plug in the USB connection, I get the following log output:
$ dmesg | grep sd

[20047.627922] sd 21:0:0:0: [sdg] Attached SCSI removable disk
Secondly, the drive is not mounted in the FS, but when I run gphoto2 I get the following error:
$ gphoto2 --list-config
*** Error ***
An error occurred in the io-library ('Could not lock the device'): Camera is already in use.
*** Error (-60: 'Could not lock the device') ***
What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed.
The output of gphoto2 is then:
# gphoto2 --list-config

I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.

View 2 Replies View RelatedCost effective (the people want cheap) solution to increase server storage space with as little impact on throughput (what I want) as possible. I have a server that sends instructions to 20 clients to perform certain tasks. The clients send gigs of data back to the server for storage.
BACKGROUND INFORMATION
Network: Gigabit Ethernet
Clients: (20) HP, Solaris, Linux
Linux Server: Dell R805 PowerEdge (QUAD Core Athlons 16 gigs of ram, 4 gigabit ports.
Selected directories are mounted (NFS) by clients. One directory to be mounted by the clients contains executable files. Mount commands are sent from the server (rsh) to the clients. Yes I know (ssh) but this is how the software was originally written so let's go with it.
The clients then receive commands to execute the binaries contained within the mounted directory. The binaries basically create an image of the clients filesystem including special applications. The client then sends the files and directories to the server which stores this �image�. This process can be reversed to restore a client to the initial baseline image.
In a nut shell, 20 clients are sending gigs of data to the server for storage. I need to attach a NAS (gigabit) to extend the storage capability of the server. The server would mount (NFS) to the hard drives on the NAS. The NAS, configured as a �direct attached storage� device (DAS), means the storage device is connected directly to the server and not the network (which makes it a DAS). This would provide direct storage expansion for the server. However, this configuration cannot be a bottleneck that significantly hinders performance.
Clients <---data---->Server<----storage---->DAS/NAS
1) Will a low end NAS (gigabit port) work? (NetGear 1TB ReadyNAS Duo, RND2110-100NAS) or something with a higher rated throughput (QNAP TS-239 Pro II)
2) Low end won't work, go with �?
3) Does the processor on the NAS play any role that would determine the performance of this configuration given that the server would mount directly to a directory on this device (DAS/NAS)?
Is there a way to determine the IO size that is being used for reads and writes to an attached storage device? I am trying to pattern the IO sequences to storage. I have seen mentions to max_sectors_kb but the notes indicated that changing this value did not change the IO size to the storage.
