Setting up SmartIO read caching for Veritas Access
In read mode, the SmartIO feature caches the file system read I/Os. To set up SmartIO for read caching for a file system, simply create the cache area.
Setting up SmartIO read caching
- For each node, to view a list of devices available to use for the SmartIO cache area, use the following command:
SMARTIO> device list node_name
Where:
node_name specifies the cluster node.
- Create the cache area on the SSD device, using the following command.
SMARTIO> cache create nodename ssddisk size fstype cachename
Where:
nodename specifies the cluster node on which to create the SmartIO cache.
ssddisk specifies a device to use for the cache area.
size specifies the SmartIO cache size.
fstype specifies the file system type (default/reserve).
cachename specifies the cache name.
- The cache area is set to read mode by default.
When a cache area is deleted or brought offline, the caching mode is not removed from the file system mount options. If you create or bring online a new cache area, the cache area inherits the existing caching mode.
If the file system mount option was previously set to any other mode, you must explicitly change the caching mode as follows:
SmartIO> fs cachemode read fs_name
- If required, you can further customize the caching behavior.
