wafl.compress.enable.failed

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.

wafl.compress.fail.rootVol

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.

wafl.compress.mark.cg.bad.hw

Severity

ALERT

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

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.
