问题 I am using keybase (a cloud base data store for your SSH and other keys) and today somehow it did not restart when I started X-Windows. As a result, the command df (and thus statvfs() in my code) would just block after telling me that the transport was down. $ df df: '/home/alexis/"/home/alexis/.local/share/keybase/fs"': Transport endpoint is not connected df: /run/user/1000/gvfs: Transport endpoint is not connected _ The prompt would sit there and never return. I don't care much that df

问题 This question already has answers here : How Do I Eject a Volume in Java? (2 answers) Closed 7 months ago . Is there any simple way to eject the D drive in Windows 7 using Java?

问题 I'm trying to code a RAMDisk, but I don't know how to mount a drive in RAM. I'm going to be writing this in Java. But could anyone point me to the way of making the disk in RAM with a letter and name. Thanks! EDIT: For clarification, I want to make a file with virtual files like stored in RAM. DataRam's Ramdisk is a good example of what I want to do. It creates a file and mounts a drive. The drive is in RAM and it writes to the file. How can I achieve this? (I wanted to create a RAMDisk for

问题 I need to know what file a specific program read. (this specific program is based on .net). Is there a recommendation for a good profiler? 回答1: Take a look at Process Monitor, it can tell you exactly when and what files are opened and closed by any Windows process, read/write operations, etc. 回答2: Can you run the program under an IDE such as Visual Studio? Are you asking what is the name of the file that the program spends most of its time reading? If so, then the simplest way to find out is,

问题 All of the instructions available online for deleting a disk from a non-existent VM relate to the older Azure UI which does not contain the same menu commands as the new Portal. Therefore I need instructions for deleting an orphaned disk using the new Azure Management Portal. Instructions for the old portal are worthless for this action. 回答1: Azure VM disks are stored in Azure Storage (blob containers). Open http://portal.azure.com, click All Resources and locate the storage account, which

问题 I want to format a hard disk via python script using subprocess.Popen. Typing the following command inside a shell worls fine. Just pay attention with this command! parted /dev/sdh mklabel gpt Warning: The existing disk label on /dev/sda will be destroyed and all data on this disk will be lost. Do you want to continue? Yes/No? I agree by typing Yes and the disk is well formatted. Rolling it inside Python subprocess, Popen exits with status code 1. I'm even not able to write 'Yes' into the

问题 I'm trying to accomplish something that was simple to do before in GCE with scratch disks. Basically I want to start an instance (now using a newly created root persistent disk), have the instance run some computation, then have the instance kill itself AND delete the root persistent disk. This was easy before the V1 api because you could use a scratch disk that disappeared when the instance was killed, however, now with V1, deleting an instance with a root persistent disk requires two calls

问题 Does anyone have experience with storing data on disk? What I have is an in-memory modelling application that can do calculations etc. Basically the data is stored as lists of objects, that have nested key-value collections like Dictionary< int, Dictionary< int, T>>. Right now I use SQL-Server as a persistance layer but I use very few features of it. So I'm thinking I could write/ read the data to disk myself to reduce dependencies and ease installation. So I wrote a little routine that

问题 I am trying to throttle the disk I/O of a Docker container using the blkio controller (without destroying the container), but I am unsure how to find out which device to run the throttling on. The Docker container is running Mongo. Running a df -h inside the bash of the container gives the following: root@82e7bdc56db0:/# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/docker-202:1-524400-916a3c171357c4f0349e0145e34e7faf60720c66f9a68badcc09d05397190c64 10G 379M 9.7G 4% / tmpfs 1
