wafl.br.redir.invalid

Severity

ALERT

Description

This event is issued if block reallocation has not been performed on an aggregate but a reallocated block was found that subsequently needs to be redirected. Block reallocation operates in two phases: first the blocks on an aggregate are moved (reallocated), later, when the block is read, the old pointers to the block are updated (redirected). This event is issued when the second phase is required without the first phase occurring. Since this may indicate on-disk data corruption, the aggregate has been taken offline.

Corrective Action

(Call support).

Syslog Message

Invalid redirection: aggr:%s vol:%s

Parameters

aggr (STRING): The name of the aggregate
vol (STRING): The name of the volume

wafl.br.redir.nospace

Severity

NOTICE

Description

This message occurs when there’s not enough free space to complete a redirect scan on a volume. The redirect scan improves performance by updating information that was changed because of block reallocation, but is not required for normal operation. This message is usually caused because reallocated blocks are shared between the active file system and a Snapshot(tm) copy and cannot be updated without using more blocks than are currently available.

Corrective Action

Create more free space in the volume by deleting Snapshot copies.

Syslog Message

The redirect scanner cannot complete its scan on '%s%s%s' because there is not enough disk space. Remove Snapshot copies.

Parameters

volname (STRING): Volume name.
app (STRING): Application UUID.
volident (STRING): Unique identifier the volume in cases where the volume name itself is insufficient.
