Table: Veritas File System features not supported in cluster file systems lists functionality that is not supported in a cluster file system. You can attempt to use the listed functionality, but there is no guarantee that the functionality will operate as intended.

It is not advisable to use unsupported functionality on SFCFSHA, or to alternate mounting file systems with these options as local and cluster mounts.

Table: Veritas File System features not supported in cluster file systems

Unsupported features	Comments
qlog	Quick log is not supported.
Swap files	Swap files are not supported on cluster-mounted file systems.
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.
