wafl.readdir.expired

Severity: ERROR
Description: This message occurs when a READDIR file operation has exceeded the timeout that it is allowed to run in WAFL®. This can be the result of very large or sparse directories, and corrective action is recommended.
Corrective Action: You can find information specific to recent directories that have had READDIR file operations expire by using the 'diag' privilege nodeshell CLI command: "wafl readdir notice show" If a directory is indicated as sparse, it is recommended that you copy the contents of the directory to a new directory to remove the sparseness of the directory file. If a directory is not indicated as sparse and the directory is large, it is recommended that you reduce the size of the directory file by reducing the number of file entries in the directory.
Syslog Message: A READDIR file operation has expired for the directory associated with volume %s%s/%s Snapshot copy ID %d and inode %d.
Parameters: volume (STRING): Volume name that the directory is in.
app (STRING): Application UUID.
volident (STRING): Volume identifier to uniquely identify the volume in cases where the volume name alone is insufficient.
snapid (LONGINT): Snapshot(tm) copy ID that the directory is in.
directory_inum (LONGINT): The inode number (fileid) of the directory.
object_uuid (STRING): UUID of the resource object.
