File system requirements for ACL-enabled VOBs
Verify that the file systems for VOB storage pools support Access Control List (ACL) authorization at the file system-level. This support is required to assign multiple groups and users to element ACLs. Depending on the operating system, you might need to perform one or more steps to enable file system ACL authorization.
The following table lists the requirements to support ACL authorization of ClearCase® VOB objects by operating system and VOB storage location. Only the operating system and VOB storage location configurations included in this list are supported.
| Operating system and VOB location | Configuration requirements |
|---|---|
| Locally-stored VOBs | |
| Windows | Supported on NTFS. No system configuration is required. |
| Solaris | Supports the following file systems: UNIX (UFS), Z (ZFS), and Veritas file system (VxFS). No system configuration is required. |
| Linux (x86_64, ppc64le, or s390x) | ACLs support must be enabled for these file systems: ext3, ext4, or reiserfs. Also, the file system must be mounted with the acl option. See the Linux documentation for your distribution for information. In some cases, ACLs support might be enabled by default. |
| AIX | File system ACLs are supported with NFSv4-style ACLs on JFS2,
which are built into the base AIX operating system. To enable NFSv4-style ACLs,, the
AIX file system must be at Extended Attribute Format - Version 2
(EAformat: V2). Use these commands to check the version
format on the AIX file system and change it to version 2 required.
|
| HP-UX(IA64) | Only JFS is supported. No system configuration is required. |
| VOBs stored on network filer | |
| Windows and Linux | For configuration requirements, see Using a network filer for ACL-enabled VOB storage. |
