wafl.nvsave.overwritingstale

Severity

NOTICE

Description

This message occurs during replay of the WAFL® nvlog, when the system discovers records associated with an offline volume. These records need to be stored in a system file on the root volume for future replay. However, a previously saved replay file already exists for this volume in the root volume. The system overwrites the stale replay file if the Consistency Point (CP) count stored in the file is less than that in nvlog.

Corrective Action

(None).

Syslog Message

Detected stale system nvlog replay file for a nonexistent volume with FSID '%d' in the '%s' root volume for WAFL nvlog %d. This stale file was overwritten because of '%s'.

Parameters

fsid (INT): File system ID (FSID) of the missing volume.
host (STRING): Owner of the root volume to which the detected nvlog records are successfully stored.
log (INT): WAFL NV log section in which nvlog records for the volume are located.
error (STRING): Reason for overwriting the existing nvsave file.

wafl.nvsave.replaying

NOTICE

Description

This message occurs when a volume comes online and detects relevant nvlog data to be replayed from the system file in the root volume.

Syslog Message

Relevant nvlog data detected for volume %s%s%s%s, FSID %d, CP count %d in WAFL NV log %d. Replaying nvlog records for the volume from a system file in the root volume.

Parameters

owner (STRING): Owner of the volume.
vol (STRING): Name of the volume.
app (STRING): Application UUID.

vol_type (STRING): Whether this message refers to NVSave files for an aggregate or a flexible volume.

wafl.nvsave.replaying.fail

Severity

EMERGENCY

This message occurs when a volume comes online and fails to replay relevant nvlog data from the system file in the root volume. The nvlog data for the volume might be lost.

Corrective Action

Take appropriate recovery action to recover from data loss, if any.

log0_replay_time (LONGINT): Milliseconds to replay nvlog records from the first NVSave file.
log0_cp_time (LONGINT): Milliseconds to complete the WAFL CP after nvlog records from the first NVSave file are replayed.
log1_replay_time (LONGINT): Milliseconds to replay nvlog records from the second NVSave file.
log1_cp_time (LONGINT): Milliseconds to complete the WAFL CP after nvlog records from the second NVSave file are replayed.
vol_type (STRING): Whether this message refers to NVSave files for an aggregate or a flexible volume.

wafl.nvsave.replaying.partial

Severity

NOTICE

Description

This message occurs when a volume comes online and does a partial replay of the nvlog data from the system file in the root volume. The reason for the partial replay is listed.

Corrective Action

(None).

Syslog Message

%s. Nvlog records from the system file in the root volume for volume with FSID %d might have been partially replayed.

Parameters

reason (STRING): Reason for the partial replay.
fsid (INT): File system ID (FSID) of the volume.

wafl.nvsave.replaying.pass

Severity

NOTICE

Description

wafl.nvsave.saving

Severity

NOTICE

Description

This message occurs during replay of the WAFL® nvlog, when records associated with a nonexistent or currently offline volume are discovered. These records will be stored in a system file on the root volume and will be replayed when the offline volume comes online.

Corrective Action

(None).

Syslog Message

Replay detected nvlog records for a nonexistent or offline volume with FSID %d and CP count %d in WAFL nvlog %d. The nvlog records will be stored in a system file in the "%s" root volume for possible future replay.

Corrective Action

Nvlog records for an offline volume were not successfully saved, data loss is possible when the volume comes back online. Take appropriate recovery action to recover from data loss, if any, when the volume comes back online.

Syslog Message

Replay detected nvlog records for a nonexistent volume with FSID %d and CP count %d in WAFL nvlog %d. Failed to store nvlog records in a system file in the "%s" root volume due to error: %s.

error (STRING): Error code.
vol_type (STRING): Whether this message refers to NVSave files for an aggregate or a flexible volume.

wafl.nvsave.saving.pass

Severity

NOTICE

Description
