It picks up a cluster configuration file from another cluster on the network where of course it does not find the local node
I've disabled openais, change the configuration to use a different ring but it is still happening.

Aug 2, 2010I am wanting to do some experimenting with some virtual machines as well as get to know some of the other distros out there.
I was just wondering if I were to construct a VM on VirtualBox, and then sometime down the road uninstall it when finished. What would be the best way to go about uninstalling as far as completely restoring the space and partition that was being used back to my main partition?
Does Virtualbox automatically do that for you?

Programming :: Construct A Quick Regex That Will Search For Six Lines Of Text
Apr 25, 2011I am trying to construct a quick regex that will search for six lines of text without a clear line break between them. It only needs to search, not replace, as I will be using in gEdit (with regex plugin) anyway.
It's for editing subtitle files. The video player I will be using them on can only cope with 3-line subtitles, so I just need to edit any in the srt file that contain four or more. There won't be many so I can do it manually. For example:
26
00:01:47,357 --> 00:01:49,359

but .* seems to mean "any character, or none", so that doesn't work. My experience of regular expressions is limited, but I do know they are very powerful when used correctly!

General :: Can't Find Boot Device - Error "Unable To Determine Major/minor Number Of Root Device"

View 2 Replies View RelatedFedora Hardware :: Full Speed USB MSC Device Detected As Input Device?
Apr 7, 2011I am working on an embedded system, which is an USB MSC device that supports some vendor specific scsi commands. I am using FC10 laptop as USB host for testing, and it runs some small apps based on sg3. All has been well for ~ a week. The FC10 laptop is able to communicate with the device and retrieve data. Suddenly, starting from today, the laptop is not able to properly detect the device. When plugged-in, the MSC device is detected as input device (I thought). This is observed from "dmesg" output and changes in "/dev/input/".The device under development is running at full speed. When I connect to winXP, no problem. A windows file explorer pops up, showing the content of the drive.Also, the FC10 has no problem with other USB flash drive (high speed).

Then one time I was charging phone over its USB port and booted Ubuntu and was pleasantly surprised when I saw phone's μSD card reader on my desktop. I now need to switch to Gento and would like to be able to work with phone there too. Lsusb tells me it's detected as Bus 007 Device 006: ID 04e8:663f Samsung Electronics Co., Ltd SGH-E720/SGH-E840but lsmod wasn't very helpful. On the list of loaded modules, I wasn't able to find one which looks like it's related to the phone.
