Yes, that's true, assuming you have no external source of verification. However, Arne said he didn't think this bug would result in data corruption, only metadata corruption. I was mostly worried about pool corruption that would cause panics or failure to import, which data level corruption would not cause. Most of the data on the pool I was worried about is media, a bad data block here or there wouldn't be too tragic. > from that pool, e.g. from a backup prior to 6214 having been introduced, > but depending on the sheer amount of data or the type of it, that might > not be even possible. Yup. This was a sucky bug :(. _______________________________________________ OmniOS-discuss mailing list [email protected] http://lists.omniti.com/mailman/listinfo/omnios-discuss
