A permanent error is a permanent error. You have a mirrored device, with no checksum errors on either side of the device (I'm guessing you reset the counter.) If there was a checksum error on only one side of the mirror, then the other side of the mirror would have been used automatically to reconstruct the correct data. But a permanent error means there was a checksum failure on both sides of the mirror, for the same data. So there is no good copy of the data anywhere. Most commonly, this type of error occurs if you had a fault in the HBA, or in RAM (and you have non-ECC ram)... Most likely there's nothing wrong with your disks, but some corruption happened in the channel that delivers data to the disks. So most likely the same corrupt data was written to both sides of the mirror, or not at all. Long story short: There is no way to recover that data. Fall back and try to find a good copy in backups. _______________________________________________ opensolaris-help mailing list opensolaris-help@opensolaris.org
