In case check_filesystem() does not error out and does not report an error, remove that error block from error lists and logs without requiring a scrub. This can happen when the original file and all snapshots/clones referencing it have been removed. Otherwise zpool status will still report that "Permanent errors have been detected..." without actually reporting any of them. To implement this change the functions introduced in corrective receive were modified to take into account the head_errlog feature. Before this change: ============================= pool: test state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A config: NAME STATE READ WRITE CKSUM test ONLINE 0 0 0 /home/user/vdev_a ONLINE 0 0 2 errors: Permanent errors have been detected in the following files: ============================= After this change: ============================= pool: test state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-9P config: NAME STATE READ WRITE CKSUM test ONLINE 0 0 0 /home/user/vdev_a ONLINE 0 0 2 errors: No known data errors ============================= Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Brian Atkinson <batkinson@lanl.gov> Signed-off-by: George Amanakis <gamanakis@gmail.com> Closes #14813 |
