File system and methods for performing file create and open operations with efficient storage allocation |
摘要 |
A client computer system of a cluster may send a request to create a file in a cluster file system. A server may create a file in response to the information and allocate space in a storage to the file. If a request to write to the file is received within a predetermined amount of time, the write may complete without requiring that additional operations be performed to allocate space to the file. If a write to the file is not received within the predetermined amount of time, the space allocated to the file when it was created may be de-allocated. The file system may additionally or alternatively perform a method for opening a file while delaying an associated truncation of space allocated to the file. If a request to write to the file is received within a predetermined amount of time, the write may be performed in the space already allocated to the file.
