From time to time it may be necessary to inform the pool administrator about an errata which impacts their pool. These errata will by shown to the administrator through the 'zpool status' and 'zpool import' output as appropriate. The errata must clearly describe the issue detected, how the pool is impacted, and what action should be taken to resolve the situation. Additional information for each errata will be provided at http://zfsonlinux.org/msg/ZFS-8000-ER. To accomplish the above this patch adds the required infrastructure to allow the kernel modules to notify the utilities that an errata has been detected. This is done through the ZPOOL_CONFIG_ERRATA uint64_t which has been added to the pool configuration nvlist. To add a new errata the following changes must be made: * A new errata identifier must be assigned by adding a new enum value to the zpool_errata_t type. New enums must be added to the end to preserve the existing ordering. * Code must be added to detect the issue. This does not strictly need to be done at pool import time but doing so will make the errata visible in 'zpool import' as well as 'zpool status'. Once detected the spa->spa_errata member should be set to the new enum. * If possible code should be added to clear the spa->spa_errata member once the errata has been resolved. * The show_import() and status_callback() functions must be updated to include an informational message describing the errata. This should include an action message describing what an administrator should do to address the errata. * The documentation at http://zfsonlinux.org/msg/ZFS-8000-ER must be updated to describe the errata. This space can be used to provide as much additional information as needed to fully describe the errata. A link to this documentation will be automatically generated in the output of 'zpool import' and 'zpool status'.
