software requirements to make detailed provisions. This time we want to compile the source code is the Android 4.4.x version, according to the information in the official website, we want to use 64-bit Ubuntu to compile, and at least 100G of disk space; On the software side, because we compiled the 4.4.x (Kitkat) version of the source code, we need the JDK 1.6, in addition, official guide has some other requirements: Python2.6--2.7,gnu make 3.81--3.8

dynamic resources available Binding if a PVC set a certain storage and access modes, and there is a corresponding PV, then the dynamic provision of resources. A control loop on master is always looking for a monitor PVC and then finds a PV to match. If a matching volume is not present, the PVC remains unbound, and the PVC is generally bound to the available matching volume. If the cluster provides a 50g PV, then the request 100g PVC will not match,

Today I learned the Linux file system, and now I want to make a small summary.First, everything in Linux is a file, and the following list is the top-level directory structure of the Linux system.Listing 1. Top-level directory structure for Linux systems/root directory ├──bin store user binaries ├──boot store kernel boot profile ├──dev store device files ├──etc Storage System configuration file ├──home　　Home directory ├──lib dynamic shared library ├──lost+found file system Recovery file ├──media

solve this problem, you only need to use the following command when you create the VG: Vgcreate–s 1M woonvg/dev/sd[b-d]4, resizing partition size 4.1, extended partition expands woon_lv1 to 50g[[emailprotected] woon_lv1]# lvextend-l 50g/dev/woonvg/woon_lv1size of Logical Volume WOONVG/WOON_LV1 changed from 40.00 GiB (10240 extent s) to 50.00 GiB (12800 extents). logical Volume WOON_LV1 successfully resized the partition is now extended to 50G, but the kernel is not aware, so be notified of the

Because the Elk server is built to allocate only 100G of disk space to the system. Later, because a large number of server logs need to be stored, only the Linux system disk space can be extended. The prerequisite is that Exsi has enough free disk space. Otherwise, the operation cannot be performed.1. Open the virtual machine's à edit the settings. Expands the disk size. I used to be 100G now to 1.1T650) t

OriginalFirst, the purposeWhen using the CentOS6.3 version of the Linux system, found that the root directory (/) is not enough space, and other directory space is very free, so this article is mainly for the existing space to adjust. First, let's look at the spatial distribution of the system: [Email protected]/]# df-h Filesystem Size used Avail use% mounted on /dev/mapper/vg_centos-lv_root 50G 14G 34G 30%/ Tmpfs 1.9G 0 1.9G 0%/dev/shm /DEV/SDA1 485M 37M 423M 8%/boot /dev/mapper

A sparse file is a file in which most of the contents of a file are empty characters.The 100G disk file created by the virtual machine is, but the system does not immediately partition the space of 100G, but only to identify the virtual hard disk files are sparse files, until the data storage, then allocate space, which can greatly save disk utilization.When a sparse file is Cp/scp/split/cat, it becomes a n

Rich has extensively documented it, still I felt it's worth pointing out again of its sheer simplicity.For instance, if you need to create a Fedora guest of size 100G, and of qcow2 format, it's as trivial as (no need for R Oot login):virt-builder fedora-20
