Linux Patch Notes for CTE v7.5.0.89

Resolved Issues

• AGT-46387 [CS1470787]: AIO/DIO for HANA backport

  Performance improvements were made for the AIO/DIO use case where a single, or small number of threads, drive a large number of write IOs.

• AGT-48812 [CS1511337]: System crashed continuously with voradmin command

  The crash was caused by a failed guard operation. A failed guard operation requires that all information pertaining to the failed operation is cleaned up. If the clean up operation fails, it can cascade into other failures including a system crash. The specific cause of the crash was that certain information was not cleaned up properly after the failed guard operation. This has been resolved.

• AGT-48926 [CS1513007]: Agent unable to communicate with DSM after CTE 7.4 upgrade

  The problem occurred in a DSM cluster when the Primary node was down. When VMD started for the first time after an upgrade, it did not find the Primary node and did not look at any of the other active nodes. The work-around for the original problem was to restart VMD. The issue is now fixed. When VMD starts, it checks to see if the DSM cluster is an active-active configuration. If it is, then it looks for the Secondary node if the Primary node is not found.

• AGT-48947 [CS1515082]: VMD failed to start after the certificate renewal

  The issue was caused by the barrier file getting modified and copied after the removal logic was executed. The solution was to remove VMD from the secfs-fs-barrier.service file.

• AGT-50547 [CS1522007]: CTE registration with External CA fails when final newline missing (vmd)

  The external CA (client_cert.pem) that the customer was using did not have a new line at the end of the file to terminate the certificate.
