wafl.raid.cft.aggr.snapshot.missing

Severity

ERROR

Description

This message occurs during an aggregate transition workflow when an aggregate Snapshot® copy created in a 7-Mode environment is missing.

Corrective Action

Return the disks to the 7-Mode environment, create the Snapshot copy for the aggregate, and then repeat the transition workflow.

Syslog Message

Aggregate transition failed for aggregate %s due to unavailability of the 7-Mode aggregate snapshot.

Parameters

aggrname (STRING): Name of the aggregate.

wafl.raid.incons.buf

Severity

ERROR

Description

This message occurs when the WAFL® kernel detects an inconsistent block on a disk. Access to the block is disabled until corrective action is taken.

Corrective Action

Use the "volume file show-inode" command with the file ID and volume name information to find the file path. If the volume is inconsistent, run wafliron as soon as possible to clear the inconsistency. For a SnapMirror® target, rebuild from the source or resynchronize. If the block is in a Snapshot copy, delete the Snapshot copy. If the problem persists, contact NetApp technical support for more options.

Syslog Message

WAFL inconsistent: bad block at VBN %llu (vvbn:%llu fbn:%llu level:%u) in %s inode (fileid:%s snapid:%u fixable:%d file_type:%d disk_flags:0x%x error:%u raid_set:%d) in volume %s%s%s%s.

wafl.raid.incons.dir.block

Severity

ERROR

Description

This message occurs when the WAFL® kernel detects an inconsistent directory block on disk, causing some entries on the directory not to appear. The message indicates the fileid and Snapshot(tm) copy of the block being accessed.

Corrective Action

The volume has a bad directory block. Use the "volume file show-inode" command with the file ID and volume name information to find the file path. Recover the directory from a backup. For a SnapMirror® target, rebuild from the source or resynchronize. If the block is in a Snapshot copy, delete the Snapshot copy. Then contact NetApp technical support.

wafl.raid.incons.snapmap

Severity

NOTICE

Description

This message occurs when WAFL detects a RAID inconsistency error in a snapmap block. The message recommends to delete the snapshot in which inconsistent snapmap resides.

Corrective Action

(None).

Syslog Message

Snapshot(snapid %u) block accounting metadata is corrupted. To avoid trapping unnecessary blocks in the snapshot, please delete the snapshot.

Parameters

snapid (INT): Snapshot copy identifier: (0) - active file system (non-zero) - refers to Snapshot copy

wafl.raid.incons.snapmap.chk

Severity

NOTICE

Description

This message occurs when the WAFL® kernel detects a RAID inconsistency error in a Snapshot(tm) copy active map block, even though the block content passes a metadata check.

Corrective Action

Contact NetApp technical support.

Syslog Message

(None).

Parameters

fbn (LONGINT): File block number.
level (INT): Buffer level.
snapid (INT): Snapshot copy identifier: (0) - active file system (non-zero) - refers to Snapshot copy

wafl.raid.incons.snapshot

Severity

ERROR

Description

This message occurs when WAFL® detects a RAID inconsistency error in a snapshot. The message indicates what snapshots have the inconsistent block, and how to recover from the inconsistency.

Corrective Action

Delete the specified snapshot(s) during the next reboot, either by using the boot menu command 'boot_snap_delete' or by using the CLI command 'vol online -r'.

Syslog Message

VBN %llu has RAID inconsistency errors on volume %s. This block is in use by one or more snapshots. These snapshots should be deleted in the next boot. The affected snapshot IDs are: %s.

Parameters

vbn (LONGINT): Virtual block number.
volname (STRING): Name of the volume.
snapstring (STRING): The string containing the list of snapid(s) of the snapshots that have the inconsistent blocks.

wafl.raid.incons.ssd.cached.buf

Severity

NOTICE

Description

This message occurs when the WAFL® kernel detects an inconsistent cached block on a ssd disk in a hybrid aggregate. Any access to this block will result in the io getting redirected to the source location on hdd disk.

Corrective Action

An error on a cached ssd block will not result in bad data being served to the reader: the io will be redirected to hdd and the correct data will be served. So, no corrective action is necessary for this case. But, if there are many errors on data cached on ssd disks, then the ssd disks may be verified for disk consistency.

Syslog Message

WAFL inconsistent: bad cached ssd block %llu (vvbn:%llu fbn:%llu level:%u) in %s inode (fileid:%s snapid:%u file_type:%d disk_flags:0x%x error:%u) in volume %s%s%s%s. IO will be redirected to the source hdd block %llu.

Parameters

vbn (LONGINT): Volume SSD block number.
vvbn (LONGINT): Virtual block number.
fbn (LONGINT): File block number.
level (INT): Buffer level.
file_space (STRING): File space: private or public.
fileid (STRING): Identifying number for the inode.
snapid (INT): Snapshot(tm) copy identifier: (0) - active file system (non-zero) - refers to Snapshot copy
type (INT): File type.
flags (LONGINT): Inode disk flags.
error (INT): Error on the block.
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.
hdd_vbn (LONGINT): Volume HDD block number.

Severity

ERROR

Description

This message occurs when the WAFL® kernel detects an inconsistent user data block on a disk. Access to this block is disabled until you recover it from a backup.

Corrective Action

The volume has an inconsistent user data block. Use the "volume file show-inode" command with the file ID and volume name information to find the file path. Recover the file from a backup. For a SnapMirror® target, rebuild from the source or resynchronize. If the block is in a Snapshot(tm) copy, delete the Snapshot copy. Contact NetApp technical support for more options.

Syslog Message

WAFL inconsistent: inconsistent user data block at VBN %llu (vvbn:%llu fbn:%llu level:%u) in %s inode (fileid:%s snapid:%u file_type:%d disk_flags:0x%x error:%u raid_set:%d) in volume %s%s%s%s.
