I am running raidz1 on a 5-disk home fileserver with the philosophy that if I do get bitten by a multiple drive failure or latent bad sectors during a rebuild, I can count on zfs to tell me which files were affected and then I'll just restore them from backup. (Unlike md raid where rebuilds seem to be much more all-or-nothing.) My underlying assumptions here are: * A disk failure where some moderate number of sectors become unreadable is far more likely than a disk going completely toast. * Even if I were running raidz2 or raidz3 I'd still want the offsite backups in case of some disaster befalling the entire array (or more likely, me accidentally rm'ing something) * It's a home fileserver used mostly for archival purposes. Unlike a business scenario, the loss of availability while I restore from backup is not going to hurt too badly. Did I miss something here or do you think this is sound?
