Veritas File System features not 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
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. |
Cached Quick I/O
|
This Quick I/O for Databases feature that caches data in the file system
cache is not supported. |
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. |
