benchmark a hard drive is failing on Fedora?

0 votes
442 views

When I try to benchmark a hard drive (from the Disk application on my fedora machine), I get:

Error opening /dev/sdc: Device or resource busy (udisks-error-quark, 0)

This disk work fine (from GsmartControl). What do I miss?

ls -l /dev/sdc*

Depending on how the application is opening it having a partition on it seems to block certain apps from opening the underlying device. It likely depends on how the application is opening it. dd always works in my experience, but other tools appear to be unhappy when they detect another user of the device.

How to clone a system to an encrypted drive in Fedora?

I have a running Fedora 21 system. I would like to make a backup of it to a USB drive, a clone that can be booted. I know how to do all the "normal" stuff (partition, LVM, mkfs, rsync, and GRUB), but I'd like the USB drive to be encrypted, and I don't know how to set that up manually (I haven't messed with encrypted filesystems under Linux before).

The system I'm backing is also headless, so no GUI tools. Any Pointers, tips, suggestions?

How do I run a script automatically when a specific drive mounts when using Fedora?

I want to execute a script every time a specific drive is mounted on the system. I have a thumb drive that has a name I've given it. When it's mounted, I want to copy the contents of my .gnupg directory to it so I can always have a current backup of my keyring.

From the research I've done, it looks like UDEV rules are the way to go but, IIRC, Fedora doesn't use UDEV anymore. How can I accomplish this now?

Where is a Camera Mount Point on Fedora?

I have plugged a digital camera into my usb port and mounted it using the popup displayed from the auto detect via konqueror (this annoys me as well). When konqueror is launched it displays the contents via Camera:/ which is okay, but subsequently I can't find any entries under /run that represent the camera. I assumed there would be a mount point under /run like there is for a usb flash disk.

Given that there appears to not be a mount point under /run, where is it mounted in Fedora 20, so that I can point dolphin (which is what should be launched from the 'Open with File Manager' prompt, not Konqueror) at the mount point rather than having to manually type Camera:/ into the address bar.
