| 39628 | To prevent a rare potential Machine Check Exception (MCE) and forced reboots on Sapphire Rapids machines, we recommend disabling the DSA offload feature. This condition can occur if the duroslight log indicates "Enabling DSA crc32 offload for reads," and can be prevented by adding dsa_read_ crc32: false and dsa_write_crc32: false under the "configurator" section of /etc/duroslight/conf.yaml. |
| 39211 | When deleting the most recent snapshot of a volume while a node holding a replica is offline, recently written data could revert to the data stored in that snapshot if the node later becomes the primary. |
| 39168 | When using DCPMM, if a snapshot is taken after an abrupt failure, recently written data could be reverted to the state captured in the snapshot. |
| 38754 | A node-manager service will fail to shut down gracefully, if the shutdown is issued before it successfully completed to power-up. |
| 38751 | The wrlat_reply_ qued statistic is inaccurate, as it reflects any other nvme command - not just writes. |
| 38043 | If encryption was turned on but enabling it failed - resulting in the creation of an 'EnableServerEncryptionFailed' event - the API service will return stale events. Any event from that point onward that exists in the system will not be returned by the "ListEvents" API. As a workaround, check if this event exists before upgrading to 3.14/3.15.1. Note that a similar issue could also occur when a cluster has double disk failure on one of the servers (or single disk failure with no EC), and Lightbits 3.2.x or older was used at the time of failure. |
| 37852 | List connected hosts could return hosts that are not connected to a volume when a volume uses IP-ACL. If other volumes exist that have ACL or IP-ACL matching the host and run over the same nodes, listing the connected hosts with a volume filter could return a host that is connected to the nodes the volume is replicated to. This scenario could occur even if the volume's IP-ACL does not match the host. |
| 37831 | In some cases, silent data corruption on an SSD could cause a node crash instead of attempting to recover the data and reporting an event. This can occur if the SSD returns invalid data rather than an I/O error. |
| 37738 | Under certain scenarios, Lightbits will cause the grub package to be updated during Lightbits installation, including the addition of new servers. On RHEL8 and derivatives, after updating Grub from "grub2-2.02-162.el8_10" to "grub2-2.02-165.el8_10", if the system is using BIOS mode it might enter the "grub rescue>" prompt upon booting. When this happens, see https://access.redhat.com/solutions/7118853 for how to restore system boot to normal operation. |
