Cause

The kernel jiffies value per second in Linux 2.6 kernel has changed from 100 to 1000. This change has impacted VVR in certain circumstances where the number of jiffies were used as timeout value. With this change in jiffies, VVR timeout value got reduced to 1/10 of the earlier value. This can result in rlink connection to timeout with following errors in /var/log/messages.

VxVM vxio V-5-0-661 could not send after max retry.
VxVM VVR vxio V-5-0-843 Disconnecting rlink rlk_nodea_rdg_rvg due to error : -2


This issue is tracked via Symantec internal incident listed in the Supplemental Materials section.

 

Resolution

This issue is fixed in following VxVM releases in Linux.

- VxVM 5.1SP1

 

 

 


Applies To

This issue applies to only Linux platform

 

Issue/Introduction

Veritas Volume Replicator (VVR) replication fails to complete due to stream errors with the message VxVM vxio V-5-0-661 could not send after max retry. This happens due to change of kernel jiffies value per second in Linux 2.6 kernel from 100 to 1000. Symptoms include rlinks going up and down frequently.
