As I am about to put together some form of file server mostly for secure storage I have looked at 2 free nas set ups both of which use ZFS. The features in ZFS sound rather attractive. I then remembered noticing that 12.3 offers the facility to install BTRFS on everything. Looking around going on what I could find it offers the same sort of advantages as ZFS so is even attractive on a desktop machine. Info in some ways is scant so have a few questions that maybe some one can answer.
Is there a walk through on installing and using ZFS on OpenSuse?
I'm not entirely clear what facilities are currently available on OpenSuse BTRFS?
Are there any walk throughs on installing BTRFS in some or all of a current installation?
Both of these systems self heal. Makes sense but the mechanisms that are mentioned work at the event - when data is read. So I assume both have some method of checking the entire disc storage set up as an when required eg weekly, monthly etc etc as some of the data on them might not be read for a long long time. Maybe they continuously check? Not sure I like the sound of that as it might encourage disk wear.
Interested in any comments on this general subject but maybe not the absence of repair software. Trouble is given the mechanisms that these systems use it is doubtful if a breakage due to say a power outrage could ever be repaired - the other point is that this can not happen in practice due to the way the new data is written. Bugs are something else. I lost a disk once due to a mod to ReiserFS. Some one decided to check unused disc space for integrity and got it completely wrong on my scsi disk and trashed it.
