The online check and repair functionality scrub isĪvailable as part of the Btrfs command line tools. Subvolumes is limited only by the space allocated to the pool. Individual file systems within the same pool of space. It allows you to create additional subvolumes that act as Subvolume support: Btrfs creates a default subvolume in its assigned pool Needed after applying updates, or to back up files. Writable snapshots that allow you to easily roll back your system if Search process that checks the entire file system at system start-up. Recovery time of a file system because it has no need for the lengthy In the context of a file system, a journal is an on-disk structureĬontaining a type of log in which the file system stores what it is about Important to maintain metadata intact, because otherwise all data on theĪ data structure on a file system that contains a variety of informationĪbout a file, including size, number of links, pointers to the diskīlocks where the file contents are actually stored, and date and time of Almost everyįile system has its own structure of metadata, which is one reason theįile systems show different performance characteristics. Of the on-disk data is properly organized and accessible. ![]() For information, seeĪ data structure that is internal to the file system. Partitioner (which is also strongly recommended). Unless stated otherwise in this section, all the steps required to set up orĬhange partitions and file systems can be performed by using the YaST Whether this data is consistent must be controlled by the application In addition, even the most sophisticatedįile system cannot replace a reasonable backup strategy.Ĭonsistency, when used in this section, do not refer to theĬonsistency of the user space data (the data your application writes to itsįiles). Each file system has its particular strengths and weaknesses, It is very important to remember that no file system best suits all kinds ofĪpplications.
