Enabling Logging in CacheFS
This section describes how you can enable logging in CacheFS. You can use the
cachefslog command to enable logging for a CacheFS mount-point. Enabling the
logging functionality may have a performance impact on the operations performed for
all the CacheFS mount-points that are using the same cache directory.
To enable CacheFS logging, follow these steps:
1. Log in as superuser.
2. To enable logging for a CacheFS mount-point, say /cfs_mnt1, enter the following
command:
cachefslog -f /tmp/logfile /cfs_mnt1
Where:
/tmp/logfile Specifies the logfile to be used.
NOTE: When multiple mount-points use the same cache directory, enabling
logging for one CacheFS mount-point automatically enables logging for all the
other mount-points.
3. To verify if logging is enabled for /cfs_mnt1, enter the following command:
cachefslog /cfs_mnt1
If logging has been enabled, the logfile is displayed.
Disabling Logging in CacheFS
You can use the cachefslog command to halt or disable logging for a CacheFS
mount-point.
To disable CacheFS logging, follow these steps:
1. Log in as superuser.
2. To halt or disable logging for the same CacheFS mount-point, /cfs_mnt1, enter
the following command:
cachefslog -h /cfs_mnt1
NOTE: When multiple mount-points use the same cache directory, disabling
logging for one CacheFS mount-point automatically disables logging for all the
other mount-points.
3. To verify if logging has been halted or disabled for /cfs_mnt1, enter the following
command:
cachefslog /cfs_mnt1
If logging has not been enabled or if it has been halted, the following message is
displayed:
