vxfs advanced mount options
The Filesystem Manager supports the following
mount options for vxfs filesystems:
Mode of Intent Logging
By default, vxfs filesystems
log file transactions
before they are
committed to disk, reducing time spent checking and repairing
filesystems after the system is halted unexpectedly.
You can configure this behavior as follows:
Log Mode: log all transactions before the system call
returns to the application. This incurs a slight performance
penalty while ensuring fast recovery.
Delayed Mode - allow some system calls to return to the
application before being logged. This increases system throughput
at the expense of data integrity.
Temporary Mode - delay almost all transaction logging.
This has the highest penalty for data integrity and is intended
for use with temporary filesystems.
Clear Blocks Before Allocating File?
clear data extents before being reallocating to another file.
This ensures that existing data is always overwritten with
zeroes before the disk space is released.
