Setup guide

Archive and delete projects as often as possible to free up space on your disk
array. Alternatively, you may use the previously described steps to reinitialise
your partition, making sure that you restore from archive only the projects
you need to work on.
NOTE For an XFS filesystem on XR-series disk arrays, keep the partition fill rate
below 90% for best performance.
Moreover, the Stone and Wire database may experience corruption if there is
too little available space on the disk where clip metadata is stored.
To avoid this problem, you can set the Stone and Wire database to
automatically shut off when free space falls below a certain threshold.
To configure the Stone and Wire database to automatically shut off when
there is too little free space:
1 As root, open the /usr/discreet/sw/cfg/sw_dbd.cfg file in a text editor.
2 Scroll to the [Disk Check] section.
3 Uncomment the Enabled and Minimum keywords.
4 Set the value of the Minimum keyword to the minimum allowed amount
of free space on the disk (in Megabytes).
If the amount of free space on the disk falls below this threshold, the
Stone and Wire database daemon automatically shuts off.
5 Optional: Uncomment the Timeout keyword, and set how often the
Stone and Wire daemon should check the available disk space. The
default value is 30 seconds.
6 Save and close the configuration file.
7 Restart Stone and Wire. Type:
/etc/init.d/stone+wire restart
Using Multi-Threaded Direct I/O
Most filesystems perform best when the I/O is parallelised across multiple
threads/processes and sent asynchronously. This allows the device to buffer
I/O operations and reorganize requests for optimal performance.
Some applications perform better than others on the same storage device,
based on how they perform their I/O. Applications that use single-threaded
buffered I/O can be slow.
