Will HTFS, EAFS AFS is and what
Thank you! |

Rather, the file system types are supported
The EAFS (Extended Acer Fast Filesystem) is the default filesystem used by SCO UNIX Operating System Versions 2.0 and 3.0. and is also the default filesystem for the boot filesystem (/stand) on SCO OpenServer products.
* Uses intent checkpointing and logging.
* Supports long filenames and symbolic links.
* Has 65,488 inodes per filesystem (less than 2^16).
* Has a 2GB maximum for file and filesystem size.
* Uses 1KB logical data blocks.
* Is a bootable filesystem and is used when creating the boot
Filesystem.
The HTFS (High Throughput 文) is a new filesystem for SCO OpenServer systems. It transparently provides significant performance improvement by using caching to increase data throughput. This is the default filesystem for the SCO OpenServer Host and Enterprise.
* Uses checkpointing. The filesystem is marked at regular clean
Intervals. If a filesystem is marked clean when the system
Halts, it may not be necessary for it to be checked by
Fsck (ADM).
* Uses intent logging. The transactions are filesystem
Recorded in a log and then committed to disk. This increases
System recovery speed with a very small performance penalty.
Intent logging works in tandem with checkpointing
* Uses a versioning to allow users to undelete files.
* Supports long filenames and symbolic links.
* Has a maximum 134,000,000 inodes per filesystem.
* Has a maximum file size of 2GB and a maximum filesystem
The size of one terabyte.
* Has a logical data block of 1KB.
* Is not a bootable filesystem.
The consist (Desktop 文) is designed for use on laptop, desktop, and notebook computers. This is the default filesystem for the SCO OpenServer Desktop product.
* Uses a more efficient and transparent disk data compression
Media format to increase the storage capacity of your disks.
* Supports long names and symbolic links.
* Can contain either user data or an inode on any block on the
Disk. The number of inodes in the filesystem can grow as
Necessary and is limited to the size of the partition.
* Has a maximum file size of 2GB and a maximum filesystem size
Of one terabyte.
* Uses a variable block size that is a multiple of 512 bytes up
To 4KB. This helps minimize wasted space at the end of
Incomplete blocks.
* Is not a bootable filesystem.
Other filesystems that are supported by SCO are included in the following list. Note that support for the AFS and S51K filesystems are installed by default and do not need to be linked into the Kernel.
* AFS (Acer Fast Filesystem)
* S51K Filesystem.
* High Sierra/ISO9660/Rockridge ROM Filesystem.
* DOS Filesystem.
* NFS (Network Filesystem)
* NUCFS (NetWare for UNIX Clients 文)
* LMCFS (LAN Manager Client 文)
* Adopts
The following is a summary of the supported filesystem types :
