VxFS Version 11 disk layout
Version 11 disk layout enables support for mounting a corrupted or inconsistent file system in read-write mode. Support for defining locality-aware allocation policies is added in DLV 11. DLV 11 enables support for multiple SmartIO cache area, and support for independent cache areas, for read and write back caching of a file system. Also, it enables support for storing file type as part of the directory entry.
The Version 11 disk layout can support files and file systems upto 256 TB only. The maximum file system size that can be created is currently restricted to 6 gigabytes. For a file system to take advantage of greater than 1 terabyte support, it must be created on a Veritas Volume Manager volume. For 64-bit kernels, the maximum size of the file system you can create depends on the block size.
Block Size | Currently-Supported Maximum File System Size |
---|---|
1024 bytes | 68,719,472,624 sectors (≈32 TB) |
2048 bytes | 137,438,945,248 sectors (≈64 TB) |
4096 bytes | 274,877,890,496 sectors (≈128 TB) |
8192 bytes | 549,755,780,992 sectors (≈256 TB) |
The Version 11 disk layout supports group quotas.The vxfsconvert (1M) command is used to upgrade ext2 or ext3 file systems to the Version 11 disk layout when the file system is not mounted.
See About quota files on Veritas File System.
Some UNIX commands may not work correctly on file systems larger than one terabyte.
Note:
Only files and file systems up to 256 TB are supported.
