With the Version 6 disk layout, you can dynamically increase or decrease the intent log size using the log
option of the fsadm command. Increasing the size of the intent log can improve system performance
because it reduces the number of times the log wraps around. However, increasing the intent log size can
lead to greater times required for a log replay if there is a system failure.
NOTE Inappropriate sizing of the intent log can have a negative impact on system performance.
See the mkfs_vxfs(1M) and the fsadm_vxfs(1M) manual pages for more information on intent log size.
