Just to update. After a resilver now I have the following (see below). From a user standpoint, I have all my files available. I wonder what “too many errors” mean exactly. Anyway, powering down and moving data elsewhere later this week. Thanks for your help
pool: Raid_A
state: DEGRADED
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.
