Objectives
- Describe the XFS filesystem
- Manage a XFS filesystem
- Describe the BTR filesystem
XFS
Its a filesystem with better features compared to the ext4 filesystem, among them
- Maximum filesystem size 16 EB (Exa Bytes)
- Maximum file size 8 EB (Exa Bytes)
- DMA (Direct Memory Access)
- Journal quota information
- Supor extended attributes
XFS Filesystem Maintenance
The mains maintenance task that can be performed on a XFS filesystem are :
- Defragmenting
- Enlarging
- Dumping
- Restoring
Those can be accomplished when the file system is mounted.
Dumping
In order to dump the filesystem we can use the next utility
xfsdump
Restoring
In order to restore the filesystem we can use the next utility
xfsrestore
To read more about XFS execute
$ man xfs $ man -k xfs
BTR
It is a filesystem with capabilities designed for high performace, one of the main features of this filesystem is :
- To make copies of entire filesystems in virtually no time
- Thanks to the COW (Copy On Write) techniques
- One can easily revert the state of the filesystem to earlier snapshots
- Maintains it own framework for adding and removing new partitions and or physical media
To read more about BTRFS execute
$ man btrfs $ man -k btrfs
