I need a command to display the next info from my hdd:
device name - filesystem - uuid - mount point
I found blkid but the mount point is not displayed, I've already look in man but there is no parameter for that
I seem to have another issue with my raid system
mount -a
mount: special device UUID=fb518c74:2b6bd0f4:66db5ce6:7e004239 does not exist
but when i do mdadm -vv --detail /dev/md5 ... this is what i get --->
/dev/md5:

I'm developing a little script that automatically detects the insertion of a usb device and tries to open the directory of this device in nautilus. I am using Python
So far I was able to sample and compare the changes that occur in the output of 'lsusb' command and get information pertaining to the addition and removal of usb devices.
Now I want to know if we can use that information (or some other info present in the usb sybsyste --/sys/bus/usb folder) to determine exactly where this device has been mounted.
I know you might recommend using 'mount' as a quick way to do the same. I have already done that, but the limitation is that mount only gives u the mountpoint information. How does one (using a program/logic) determine which mount point corresponds to which device.
If I were to plug in two devices together, and both were automatically mounted, how will I be able to tell which mountpoint corresponded to which device? the output of lsusb provides no information whatsoever about where the device is mounted. So its kind of a deadlock
from lsusb ive been able to gather : Device name, serial and bus number and device number
Another thing i've noticed is the 'autoplay'. Whenever I insert a my music player into my computer, it gets mounted automatically and I'm presented with options about simply opening the file or playing it with rhythmbox... now if all that was being done was polling the output of mount, they would not be able to know that the device inserted was a music player (that info u can get from the /sys/bus/usb folder only using the device class and subclass info). So obviously the two are linked somewhere...
I have a program which mounts /dev/sdb1 for which I lack the source code. This device does not exist on my RedHat 9 system and I want to create /dev/sdb1 such that it's an alias for /dev/hdb1 Can I do this? with MAKEDEV?
I need to have an alias which will allow it to mount, not create a symbolic link to an already mounted directory. i.e. 'mount /dev/sdb1 /mnt/harddrive' should actually mount /dev/hdb1
How do I configure my Debian installation to mount external USB drives to mount points based on the volume names of the drives? For instance, if I have a thumb drive with the volume name of "SWORDFISH," how do I have Linux mount it at /media/SWORDFISH? I'm aware that this can be setup in FSTAB, but that requires that I know the UUID of the device beforehand and that I take the time to set each external device up in FSTAB first. That does nothing for me when I have a thumb drive that has never been plugged into my computer before.
This seems to be setup by default in Ubuntu/Kubuntu, but is not working for me with a fresh installation of Debian Squeeze and KDE4. I've spent the past 2 hours Googling for a solution and have turned up nothing. UPDATE: My results are inconsistent. Sometimes Debian mounts devices to mount points based on the volume names, and other times it gives them generic mount points (e.g. /media/usb1).
I have gone over the thread "Learn The DD Command Revised" (It was Fantastic) in the search for a solution to my query.
I have seen posted elsewhere that this code is supposed to be able to change the UUID number of NTFS partitions (useful when multi-booting with Grub2 and cloning partitions). Here is the code:
Code:
sudo dd if=/dev/urandom bs=80 count=1 | xxd -l 80 -c 8 | tail -1 | xxd -r - /dev/sda1
This is assuming that I want to change the UUID on the 1st partition on the 1st hard drive >>>sda1<<<
If I was trying to modify the 2nd partition on the 1st hard drive it would be >>>sda2<<<
[Code].....
NOTE: I was doing this while booting from Ubuntu's Live CD version 10.04.1 LTS (In case that is a factor)
I run a headless Ubuntu 8.04 server, which acts as a web, email and file server. I am sticking with 8.04 as it is a LTS release and will upgrade to the next LTS when it is released.
I have two external USB drives, that I need to mount at boot. I have been using /etc/fstab up until now, with the following entries:
Code:
However, as I gather from doing searches is quite common, occasionally I get an error during boot (causing the system to drop to a recovery shell) because the USB drives take time to wake up and the system hasn't found them by the time it reads /etc/fstab.
From doing searches, it seems there is nothing you can do to fstab to fix this, so you need to mount them using an rc.local script instead, using:
Code:
The problem is, as I have two USB drives, their /dev/sdxx location changes between boots. I thus want to use UUID codes as I do in fstab, however I haven't found anything about this.
Does anyone know how I can use the mount command and UUID to mount a drive in rc.local and what options I have to use the mount the drive with the same options that I am using in my fstab entry? Obvisouly, I can't refer back to fstab using the mount command, because then I will still get the boot error issue if they are listed in fstab. And there is no space internally for the USB drives as there is already two internal drives.
Is the mount point for external media (like USB) always /media?
Because in a Debian system, if I plug in any USB device that goes to the /media folder. So is it the case with all the other Linux flavors like Fedora, Ubuntu, etc. If a USB device is automatically mounted will it always go to the /media directory?
I am not concerned about the name of the devices. I am looking for every external media (like USB) to be listed under /media directory so that my code can run on any flavor of Linux.
I have a CentOS 5 production server with multiple OS-managed RAID-1 sets. I'd like to add a new mirrored set and move the /var partition to the new drives. On a non-RAID system I would boot from the install CD to edit fstab and copy the existing files to the new drive, but I'm pretty sure booting off the install CD does not recognize my RAID setup.
View 2 Replies View RelatedI'm using ext3 and I have my / partition on sda3. This is a full install, it has /bin /home etc etc on it, the only thing I have is sda1 is /boot and sda2 is swap.
I've configured my system to mount sda4 as /home/user as the system boots up, which puts all of my data on sda4.
My question is this. How do I access any data left in (sda3) /home/user? (Because trying that won't work). Is there some way to use a direct path? Like /device/sda3/home/user?
I have a directory, /root/backup, that I mount and run a bunch of rysnc scripts against to backup my box. I'm running into a very recent problem where when I run this command:
A directory that once looked like this:
Goes to this:
It changes from root to www (another user on my system) and I have no idea why.
When I look at the /mount/procs file, I see this:
So it looks like the uid is correct...
I believe this is what is causing my rsync scripts to fail (they only copy over directories and not the files in those directorys and I get a lot of permissions failed errors)
All of this is run as root in cron jobs
As a note, here is a sample rsync command:
In my machine, there are 2 mount points - / and /userdata. From the root user, I want to create an oracle user at the /userdata mount point, i.e the home of the oracle user should be mounted on /userdata.

View 4 Replies View RelatedIs there any C function that will translate UUIDs into device names? I have a little graphical mount tool that can read user-mountable device names from /etc/fstab and lets you cycle through the list and mount or unmount them. But it doesn't work with UUIDs, which are preferred these days. Is there any way around this?

I am copying some backup files to a NAS by connecting an NFS export on the NAS to a mount point on my linus box. I then copy the files to it with a cron job that runs nightly. I have mounted the NAS to /mnt/nas. How can I test that the mount point is active before I copy to it? I wouldn't want to copy to /mnt/nas unless it was actually connected to the NAS.

I have a program that can create a fuse. For that i have to specify a mount point , like mono ccfs /mount. But how will I make /mount to be a fuse mount point? I donno whether my question sounds right or makes sense. But I want to create a fuse mount basically to provide it to the program. I dont hv any device or fs to mount initially .

View 4 Replies View RelatedI'm using some software that using mount point such as truecrypt. I also mount shared folder on other machine (fileserver) and publish it using ftp. The problem is when the truecrypt volume dismounted or the shared folder mount point loosing connection to the fileserver, user can write to the mount point without knowing that they actually not writing to the truecrypt volume or to the shared folder.
My question is, when sometime the server reboot and truecrypt volume is not mounted yet, how to prevent write to the mount point? I dont run truecrypt mount automatically for security reason.Some question for shared folder, if fileserver restart and the shared folder mount point got disconnected, how to prevent write to the mount point?
I have a samba share that I mount locally at boot through fstab. The share is writable and if I access the share directly, say with konqueror and smb (smb://hostname/sharename) then I can do anything I want (create, write, delete, edit, files/directories). I have a mount point on my local machine
Code:
/shares/mp3
and I (username dtest) was unable to do anything except read files and create directories trying to do them to the local mountpoint except as root. I figured it would be a matter of
Code:
chown -R dtest /shares/mp3
but I was unable to do that even as root, I kept getting permission denied. When I did
Code:
ls -alt /shares/ it told me the owner was 1000 and the group was root. Dtest was already a member of the root group and I was able to
Code:
chmod -R 774
as root but I still couldn't do anything except read and create directories directly via the mountpoint. Ultimately I solved this by changing the uid of user dtest via kuser and then just chowning my home directory back to dtest. It seems like as root I should be able to change the owner of the directory. I know it's because this is a samba share, but it doesn't make any sense why root couldn't just chown it. Is there another way to change the owner of a directory, or is this set by the machine hosting the samba share?
Using SUSE 11 with Gnome. I mounted a CIFS share from a Windows server as /mnt/win. With the file browser, I can browse to file system/mnt/win and then the files and folders of the Windows share come up fine and I can open them. When I use the file browser to browse to network, the server hosting this share is listed. Then I browse to that server and it lists no shares (nothing at all). I can't go any further than the server. Is there a separate authentication necessary for the file browser to see this share from the network place?

View 9 Replies View RelatedOn SUSE 11.2 when a CD or DVD is automounted (in the /media directory) it appears that the mount point chosen for the disk always has extra blanks at the end of the mount.
For example, if the label on the CD was DISK-001, the mount point chosen by SUSE is
/media/DISK-001 /
In 11.1 (and earlier) the mount point would have been
/media/DISK-001/
I'm assuming that the trailing blanks are filling in unused or blank chars at the end of the CD label.
Is there any way to change this annoying behavior? I much prefer NOT to have trailing blanks in the mount point.
I have servers installed with RHEL 4 2.6.9-89.0.9 ELsmp. I tried using uuid and label in /etc/fstab to automount usb drives to mountpoints that I specify after reboot. Unfortunately, it just does not work in all my RHEL4 servers. After every reboot, /etc/fstab will be automatically modified and all configurations related to my USB drives will be changed. Irregardless of whether i use UUID or LABEL in my /etc/fstab.However, it works on RHEL5. But, upgrading is not an option in my environment. I have been googling around looking for alternatives but everything seems to point back to using UUID or LABEL in /etc/fstab. Anyone has tried something that works? Please help me, thank you.
