Hi, I think you are saying that you copied the data on this system from a previous system with hardware problems. It looks like the data that was copied was corrupt, which is causing the permanent errors on the new system (?) The manual removal of the corrupt files, zpool scrub and zpool clear m

Hi-- The best approach is to correct the issues that are causing these problems in the first place. The fmdump -eV commnand will identify the hardware problems that caused the checksum errors and the corrupted files. You might be able to use some combination of zpool scrub, zpool clear, and remo

Hi Gary, To answer your questions, the hardware read some data and ZFS detected a problem with the checksums in this dataset and reported this problem. ZFS can do this regardless of ZFS redundancy. I don't think a scrub will fix these permanent errors, but it depends on the corruption. If its da

Thanks. From what I read on the forum, it also seems to be a problem with physical installs where a drive hastily reports a cache flushed to disk to improve benchmarks. Following advice from Sun, I lodged a bug report because of the core dumps on failed assertion (#5949). Hopefully a zdb bug f

Can't help with recovering your data but can shed some light on how this may have happened, its in another old thread. This problem may happen if ZFS Thought that the data has been written but its not! It can happen in virtual machine environment as VM has to go through host OS buffers which ma
