wafl.dir.convert

Severity

NOTICE

Description

This message indicates that CIFS directory conversion is in progress and WAFL will not hang due to timeout. Directory conversion happens the first time a volume with 8.3-format names is accessed by a CIFS client.

Corrective Action

(None).

Syslog Message

WAFL %s directory conversion in progress.

Parameters

type (STRING): Type of directory operation (revert/convert).

wafl.dir.convert.denied.2big

Severity

ERROR

Description

This message occurs when access to a directory is rejected because an attempted operation requires the directory to be converted to Unicode format and the directory is too large to be converted quickly. Directory conversion is required for a directory with 8.3-format names to be accessed by a CIFS or NFSv4 client.

Corrective Action

Use the "volume modify" command to enable the "convert_ucode" option on the volume experiencing the rejected access, and then retry the access attempt. Note that this might result in system performance degradation or temporary loss of service while the conversion occurs. Search on "Converting existing directories to Unicode format" for more information.

Syslog Message

Access to large directory on volume MSID:%u, file ID:%u rejected for requiring conversion.

Parameters

msid (LONGINTHEX): Volume master data set identifier (MSID) of the volume experiencing the rejected access.
fileid (INT): File identifier of the directory experiencing the rejected access.

wafl.dir.depth.max

Severity

ERROR

Description

This message occurs when a directory depth reaches its maximum depth limit. The default maximum depth is 2000.

Corrective Action

Reduce the depth of the directory, by moving directory hierarchy to higher levels.

Syslog Message

Directory depth for inum %d in volume %s%s exceeds the maximum directory depth limit. To fix this issue, please reduce the directory depth.

Parameters

fileid (INT): Fileid of the directory for which directory depth reached its maximum limit.
vol (STRING): Volume in which directory depth reached its maximum limit.
app (STRING): Application UUID.
volident (STRING): Unique volume identifier in cases where volume name itself is insufficient.

wafl.dir.duplicate.hash

Severity

NOTICE

Description

This message occurs when a directory entry has a duplicate index hash for longname and dosname/altname is deleted from the directory.

Corrective Action

(None).

Syslog Message

An entry with duplicate index hash is found in directory inum %d in volume %s%s%s. Directory index clears to fix this issue.

Parameters

fileid (INT): File ID of the directory.
vol (STRING): Volume name.
app (STRING): Application universal unique identifier(UUID).
volident (STRING): Unique volume identifier in cases where volume name itself is insufficient.

wafl.dir.fileId.err

Severity

ERROR

Description

This event is issued when directory prefetch results in inconsistent file identifier data. The fh[0] to fh[4] parameters represent the encoded filehandle value.

Corrective Action

If this error condition occurs, contact NetApp technical support for further assistance.

Syslog Message

wafl_prefetch_dir_inos: inconsistent fileid %d in %s directory {x%x %d %d %d %d}.

Parameters

fileId (INT): The file identifier
ino_type (STRING): The inode type
fh0 (INT): fh[0]
fh1 (INT): fh[1]
fh2 (INT): fh[2]
fh3 (INT): fh[3]
fh4 (INT): fh[4]

Severity

ERROR

Description

This message occurs as a warning when a parent directory reaches its maximum link limit within a specified time interval and the no of parent directory reached maximum hard link limit reached the upper limit. A directory has only one parent directory, which counts as a hard link. All other hard links are from the directories contained within this directory. The link to the parent directory cannot be removed.

Corrective Action

Use the "volume file show-inode" command with the file ID and volume name information to find the file path. Reduce the hard link count of this directory by moving some of its subdirectories to another directory, or remove some of its subdirectories.

Syslog Message

This is the last warning for failure to create a new sub-directory since parent directory with fileid %d in volume %s%s has reached its sub-directory limit.

Parameters

fileid (INT): File ID of the parent directory that has reached its maximum hard link limit.
vol (STRING): Name of the volume in which the parent directory resides.
app (STRING): Application UUID.
volident (STRING): Unique volume identifier (UUID) of the volume in which the parent directory resides, when the volume name alone is insufficient.

Severity

ERROR

Description

This message occurs when a parent directory surpasses 90% of its maximum hard link limit. The total hard link count for a directory is the number of its subdirectories plus other hard links to the directory.

Corrective Action

Use the "volume file show-inode" command with the file ID and volume name information to find the file path. Move some of the parent directory's subdirectories to a different directory. Take care not to create too many new subdirectories in the parent directory that is reaching its limit until you reduce the hard link count.

Syslog Message

The directory with fileid %d in volume %s%s%s is approaching the maximum link limit of %d. Reduce the number of links to the existing parent directory.

Parameters

fileid (INT): File ID of the parent directory that has surpassed 90% of its maximum hard link limit.
vol (STRING): Name of the volume in which the parent directory resides.
app (STRING): Application UUID.
volident (STRING): Unique volume identifier (UUID) of the volume in which the parent directory resides, when the volume name alone is insufficient.
maxLink (INT): Maximum number of hard links for the parent directory.

Severity

ALERT

Description

This message occurs as a warning when a directory has reached its maximum hard link limit and the specified time interval is exceeded.

Corrective Action

Use the "volume file show-inode" command with the file ID and volume name information to find the file path. Reduce the hard link count of this directory by moving some of its subdirectories to another directory, or remove some of its subdirectories.

Syslog Message

(None).

Parameters

fileid (INT): File ID of the parent directory that has reached its maximum hard link limit.
vol (STRING): Name of the volume in which the parent directory resides.
app (STRING): Application UUID.
volident (STRING): Unique volume identifier (UUID) of the volume in which the parent directory resides, when the volume name alone is insufficient.
maxLink (INT): Maximum number of hard links allowed.

Severity

ERROR

Description

This event occurs as a warning when a parent directory reached its maximum hard link limit within a specified time interval and the no of parent directory reached maximum hard link limit is below the upper limit.

Corrective Action

Use the "volume file show-inode" command with the file ID and volume name information to find the file path. create new subdirectories in a different parent directory. Alternatively, move some of the current parent directory's subdirectories to a different directory.

Syslog Message

A request to make a subdirectory in parent directory with fileid %d in volume %s%s could not be handled because the parent directory has reached its link limit; use a different parent directory or reduce the number of hard links by moving some of its subdirectories to a different directory.

Parameters

fileid (INT): File ID of the parent directory that has reached its maximum hard link limit.
vol (STRING): Name of the volume in which the parent directory resides.
app (STRING): Application UUID.
volident (STRING): Unique volume identifier (UUID) of the volume in which the parent directory resides, when the volume name alone is insufficient.

Severity

EMERGENCY

Description
