Veritas File System features not in cluster file systems
Table: Veritas File System features not in cluster file systems describes functionality as not supported and may not be expressly prevented from operating on cluster file systems, but the actual behavior is indeterminate.
It is not advisable to use unsupported functionality on SFCFSHA, or to alternate mounting file systems with these options as local and cluster mounts.

QuickLog is not supported.

Swap files
|
Swap files are not supported on cluster mounted file system.

mknod
|
The mknod command cannot be used to create devices on a cluster mounted file system.
|
Cache advisories
|
Cache advisories are set with the mount command on individual file systems, but are not propagated to other nodes of a cluster.
|
Commands that depend on file access times
|
File access times may appear different across nodes because the atime file attribute is not closely synchronized in a cluster file system. So utilities that depend on checking access times may not function reliably.
