XFS File System
XFS is a high-performance journaling file system. HCE only inherits some of open-source XFS features from the community.
Constraints
1. The formatting options inobtcount=1, rmapbt=1, and reflink=1 are not available.
2. The mount options discard, logdev=device, noattr2, and ikeep are not available.
3. Only the disk sector size of 512 bytes is available.
4. If remount is used to mount an XFS file system, only pairwise combination between the two option sets (inode32/inode64 and ro/rw) is available.
If unavailable parameters are used, unexpected results may occur. For example, if logdev=device is used, I/O timeout may occur in some cases.
How to Use
XFS features are from the open-source community. You can use them in the same way as you are using open-source features. For details, see the community documentation.
To use the XFS file system, the kernel version of HCE must be kernel-5.10.0-182.0.0.95.r1941_123.hce2 or later. You can run uname -r to check the kernel version.
