What we know: 1) The command can detect corruption, but 2) the command has internal limits to avoid excessive memory consumption.=20 These limits probably seemed reasonable at the time but they are easily rea= ched by a lot of people on perfectly healthy pools. Presumably the limits need t= o be adjusted. 3) The #2 false positive is scaring the heck out of people for no good reas= on. If you read the github bug https://github.com/openzfs/zfs/issues/15030 you'= ll see that people have been recovering pools. On linux they set zil_replay_disable (via procfs) to mount the damaged pool and then and zfs_recover (via procfs) and run a scrub. We have equivalent sysctls. YMM= V of course. --=20 You are receiving this mail because: You are the assignee for the bug.=
