VxVM uses an integer variable to store the starting block offset of a sub-disk in a RAID5 column.
This variable overflows when a sub-disk is located at an offset greater than 2147483647 blocks (1TB) and results in a failure to start the volume.
This issue is tracked via incident e2657797.
Resolution
VxVM code is now modified to handle integer overflow conditions for RAID5 volumes.
This issue is fixed in the VxVM 5.1SP1RP2P2HF9 hotfix for Linux platform.
This hotfix requires the 5.1SP1RP2P2 patch to be installed on the system, which can be downloaded from: https://sort.Veritas.com/patch/searchmatrix/22/3/4
Please contact Veritas Technical support to obtain the hotfix for this issue.
Applies To
This issue applies to all 5.x Veritas Volume Manager (VxVM) releases.
