April 1, 20251 yr Hi woke up to seeing a bunch of uncorrected sync errors this morning, was a bit odd to say the least, currently running a parity correcting sync, please see logs attached. Currently have 5644 Errors at 27%, but doesn't seem to be climbing, anyway of seeing what's gone on mordor-diagnostics-20250401-1725.zip
April 1, 20251 yr Community Expert Errors appear to be all on paritity2, once that's done, run another check to confirm 0 errors.
April 4, 20251 yr Author Ok so the correcting check finished, and now the non correcting check has also finished, with no errors. Please find logs attached, anything else I need 2 do? mordor-diagnostics-20250404-0643.zip
