AccessCache.NearLimits

Severity

ALERT

Description

This message occurs when the access cache module is near its limits for entries or export rules. Reaching these limits can prevent new clients from being able to mount and perform I/O on the storage system, and can also cause clients to be granted or denied access based on stale cached information.

Corrective Action

Ensure that the number of clients accessing the storage system continues to be below the limits for access cache entries and export rules across those entries. If the set of clients accessing the storage system is constantly changing, consider using the "vserver export-policy access-cache config modify" command to reduce the harvest timeout parameter so that cache entries for clients that are no longer accessing the storage system can be evicted sooner.

Syslog Message

The exports access cache module is near its limits for entries (current count : %u, warning threshold : %u, limit : %u) or export rules across entries (current count : %u, warning threshold : %u, limit : %u).

numEntriesCurrent (INT): Current number of entries in the cache.
numEntriesWarningThreshold (INT): Warning threshold for number of entries.
numEntriesLimit (INT): Limit on the number of entries.
numRulesCurrent (INT): Current number of export rules in the cache.
numRulesWarningThreshold (INT): Warning threshold for number of export rules.
