Nope, not that I am aware of. . It might be very helpful to have a wiki next to this mailing list, where all the good experience, all the proved solutions for "situations" that are brought up here, could be gathered in a more permanent and straight way. . To your questions I would add: what's best practice in setting options for performance and/or integrity... (yeah, well, for which use case under which conditions) a mailinglist is very helpful for adhoc probs and questions, but it would be nice to distill the knowledge into a permanent, searchable form. . sure anybody could set up a wiki, but... it would need the acceptance and participation of an active group to get best results. so IMO the appropriate place would be somewhere close to gluster.org? . regards Bernhard > >> 2) What do you do if a drive has already failed? > RAID6 > >> 3) What do you do if a peer is about to fail? > Get a new peer ready... > >> 4) What do you do if a peer has failed? > Replace with new peer... > >> 5) What do you do to reinstall a peer from scratch (i.e. what >> configuration files/directories do you need to restore to get the host >> back up and talking to the rest of the cluster)? > Bring up a new peer.
