Got three emails: No details on the '-e' option, but by me RTFM this is only for enableing slices in a RAID 5 metadevice. One useless, the other two (Matthew Stier and Darren Dunham) with background information on the structure and how to do a complete replacement of the mirror. Basically, we didn't have a window for doing a complete replacement and reload of the 27Gb of data. So detached d46, cleared it, recreated, and tried to reattach. Got read errors on the sync, so no good. The database is up and running on the 'bad' mirror, so we will leave it for a day and try to get a window for a complete destroy/recreate/reload operation. -- ---------------------------------------------------- Andrew Stueve andrew.stueve at wcom dot com ---------------------------------------------------- Original: > I have a 10 drive 0+1 mirror in an e450.
