Fixed In:

Opened: Oct 22, 2015
Severity: 3-Major

Symptoms

The sending of the configuration files in /config from the primary blade to secondaries may be delayed if a large number of other files were concurrently modified on the primary blade that also need to be synchronized to the secondaries.

Impact

Rebooting a secondary during sync may have undefined behavior.

Conditions

This only affects chassis platforms.

Workaround

None

Fix Information

The sending of the configuration files in /config from the primary blade to secondaries could have been delayed if a large number of other files were concurrently modified on the primary blade that also need to be synchronized to the secondaries. There is now a separate queue for each directory mirrored between devices. A large number of file changes outside of /config will no longer affect file syncs in /config.
