raid.stripe.replay.bad.block

Severity

ERROR

Description

This event is issued when we encounter a bad block buffer entry in NVRAM during stripe replay (indicating corrupted NVRAM). Reparity will start automatically and update parity in stripes involved in recent writes.

Corrective Action

Need to replace NVRAM if observed repeatedly during different boot-ups.

Syslog Message

Bad block buffer entry in NVRAM.

Parameters

(None).

raid.stripe.replay.bad.checksum

Severity

ERROR

Description

This event is issued when we encounter a checksum error in NVRAM during stripe replay (indicating corrupted NVRAM). Reparity will start automatically and update parity in stripes involved in recent writes.

Corrective Action

Need to replace NVRAM if observed repeatedly during different boot-ups.

Syslog Message

Checksum error in NVRAM.

Parameters

(None).

raid.stripe.replay.bad.key

Severity

ERROR

Description

This event is issued when we cannot find a block buffer using a key during stripe replay (indicating corrupted NVRAM). Reparity will start automatically and update parity in stripes involved in recent writes.

Corrective Action

Need to replace NVRAM if observed repeatedly during different boot-ups.

Syslog Message

Stripe %llu: cannot find NVRAM slot using key %d in %s %s.

Parameters

stripe (LONGINT): The stripe number.
key (INT): The key used.
vol_type (STRING): Volume type.
vol (STRING): Aggregate name if found, otherwise NOT FOUND.

raid.stripe.replay.bad.stripe

Severity

ERROR

Description

This event is issued when we encounter a bad stripe entry in NVRAM during stripe replay (indicating corrupted NVRAM). Reparity will start automatically and update parity in stripes involved in recent writes.

Corrective Action

Syslog Message

Bad stripe entry in NVRAM.

Parameters

(None).

raid.stripe.replay.nvgen.mismatch

Severity

NOTICE

Description

This message occcurs when RAID encounters an NVRAM generation mismatch for an aggregate during stripe replay. Reparity will start automatically and update parity in stripes involved in recent writes.

Corrective Action

(None).

Syslog Message

NVRAM generation mismatch for %s %s%s.

Parameters

vol_type (STRING): Volume type.
owner (STRING): Owner of the affected aggregate.
vol (STRING): Name of the aggregate.

raid.stripe.replay.plex.unavailable

Severity

NOTICE

Description

This message occurs when RAID encounters an NVRAM stripe entry for an offline or failed plex during stripe replay. Reparity will start automatically when the plex comes online. At that time, reparity will update parity in stripes involved in recent writes.

Corrective Action

(None).

Syslog Message

Plex %s in %s %s%s is offline or failed.

Parameters

plex (STRING): Name of the plex.
vol_type (STRING): Volume type.
owner (STRING): Owner of the affected aggregate.
vol (STRING): Name of the aggregate.

raid.stripe.replay.pzero.mismatch

Severity

ERROR

Description

This event is issued when the checksum of the parity block (as stored in the stripe slot) does not match the actual checksum of the parity block. This indicates corrupted NVRAM contents. Reparity will start automatically and update parity in stripes involved in recent writes.

Corrective Action

Need to replace NVRAM if observed repeatedly during different boot-ups.

Syslog Message

Parity block checksum mismatch detected in NVRAM for stripe %llu in %s %s.

Parameters

stripe (LONGINT): The stripe number.
vol_type (STRING): Volume type.
vol (STRING): Aggregate name if found, otherwise NOT FOUND.
