Severity: NOTICE
Description: This message occurs when WAFL compression on container file level is automatically enabled on a volume.
Corrective Action: (None).
Syslog Message: WAFL auto adaptive compression automatically enabled in %s "%s".
Parameters: volume_identifier (STRING): Volume identifier.
volume (STRING): Volume name.

Severity: NOTICE
Description: This message occurs when WAFL compression on container file level is enabled or disabled on a volume.
Corrective Action: (None).
Syslog Message: WAFL container compression state changed in %s "%s" to "%s".
Parameters: volume_identifier (STRING): Volume identifier.
volume (STRING): Volume name.
message (STRING): Whether enable or disable.

Severity: INFORMATIONAL
Description: This event is issued when FAS compression can not be enabled on a volume. The following reasons might be causing the problem: FAS compression might not be supported on the software release you're running; the volume is not a flexible volume or it is a root volume or snaplock volume; the compression/de-compression scanner is already active; or a clone operation is already underway.
Corrective Action: (None).
Syslog Message: Compression could not be enabled on volume "%s" at this time. Check the volume configuration and retry.
Parameters: vol (STRING): Volume name.

Severity: NOTICE
Description: This message occurs when an administrator attempts to enable compression on the root volume. Compression cannot be enabled on the root volume.
Corrective Action: (None).
Syslog Message: '%s' is the root volume and compression cannot be enabled on the root volume.
Parameters: vol (STRING): Volume name.

Severity: ALERT
Description: This message occurs when the FAS compression writes bad blocks for an inconsistent or corrupted compression group due to hardware errors.
Corrective Action: Restore the corrupted file from the Snapshot copy, or contact NetApp technical support
Syslog Message: FAS compression: Writing bad blocks, at fbn:%llu level:%u in %s inode (fileid:%d snapid:%u) in volume %s%s%s%s.
Parameters: fbn (LONGINT): File block number.
level (INT): Buffer level.
ino_type (STRING): Inode type
fileid (INT): Identifying number for the suspect inode.
snapid (INT): Snapshot(tm) copy identifier: (0) - active file system (non-zero) - refers to Snapshot copy
owner (STRING): Owner of the volume.
vol (STRING): Name of the volume.
app (STRING): Application UUID.
volident (STRING): Uniquely identifies the volume in cases where the volume name itself is insufficient.

Severity: ERROR
Description: This message occurs when the FAS compression writes bad blocks for an inconsistent or corrupted compression group due to software errors.
Corrective Action: Restore the corrupted file from the Snapshot copy, or contact NetApp technical support
Syslog Message: FAS compression: Writing bad blocks, at fbn:%llu level:%u in %s inode (fileid:%d snapid:%u) in volume %s%s%s%s.
Parameters: fbn (LONGINT): File block number.
level (INT): Buffer level.
ino_type (STRING): Inode type

owner (STRING): Owner of the volume.
vol (STRING): Name of the volume.
app (STRING): Application UUID.
volident (STRING): Uniquely identifies the volume in cases where the volume name itself is insufficient.

Severity: NOTICE
Description: This event is generated when the FAS compression of existing data for volume deletes checkpoint.
Corrective Action: (None).
Syslog Message: vol compress: Checkpoint deleted for compression of existing data for volume "%s%s%s".
Parameters: vol (STRING): Name of the compressed volume.
app (STRING): Application UUID.
volident (STRING): To uniquely identify the volume in cases where volume name itself is insufficient.
