when I read these py files, I gave up. The file size is determined by the parameters set in the kickstart file. 1. Create an empty raw file to store user data, including development code. There are two ways to achieve this. For example, we want an additional 5g space. Method 1: qemu-img create, which can be described in detail through man qemu-img. Example: qemu-img create wei. raw 5G Method 2: dd, this

The specific/boot only needs MB.The following is my Partition Scheme:Hard Disk 500 GB Server partition solution:Partition size/1G-2G (minimum 150-250 MB)/Boot 32 M-100 M (boot partition, up to M)/Opt 100 M-1G (Additional Application)/Tmp 40 M-1000 M (the maximum value can be about 1 GB.

For example, when testing the storage system, we need to reduce the remaining disk space by 5 GB, the simplest way is to copy a 5g file, but where can we get a file of this size? Maybe you want to find a file, copy it continuously, and merge it at last, this is also a method, but with dd, you will be e

1. Change the archive pathIn oracle10g, the default archive path is $oracle_base/flash_recovery_area. For this path,Oracle has a limitation that only 2G of space is available to the archive log by default, and you can use the following two SQL statements to see its limitations1. Select * from V$recovery_file_dest;SQL >show parameter Db_recovery_file_dest (this is more friendly and intuitive some)When the number of archived logs is greater than 2G, there is no more space to accommodate more archi
