Give me a clues as to where to start that you haven't found by googling and reading the comparisons with other FS. Its a btree FS, said to be the successor to Reiser and offering mechanisms for dealing with SDD. If offers many optimizations that we're probably not in a position to make use of yet. U've run systems with only BtrFS as the whole drive. Right now I have a 1T drive with LVM and all of /+/usr is BtrFS and all of /home is another BtrFS. Photos, music, database and email ARCHIVE (i.e. big files) are still Reiser. There is a LOT of literature on the BtrFS just a google away. Start with that until you have specifics to ask and them come back to me. -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

As an old Reiserfs fan I'm interested in trying BtrFS, but I ran into a fatal bug last year with partitions exceeding 16-TB. I reported the issue on Bugzilla, but haven't followed up since then. Is it safe now for large partitions? Regards, Lew -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

me too, but factory installed more than 10 partitions and volums, this I fail to really understand. I only got that volumes are btrfs partitions nemas, but I never had 10 partitions for the same system -( jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Anton, I think the question was: "Why did the factory install create 10 btrfs partitions/volumes?" jdd What did you tell the installer to create? /, /home, /boot? -- David C.

Anton,
I think the question was:
"Why did the factory install create 10 btrfs partitions/volumes?"
sort of, I was a bit tired and made more typos that I should, and don't know the right words for this new thing
What did you tell the installer to create? /, /home, /boot?
all default. I see now that there are only 3 partitions (usual: swap, / and /home), but the list I give in the previous post is also displayed in the install partitionner, I wonder how to deal with it, say if the proposed partitionning do not fit the particular install? I speak about this here because I understood factory is becoming the rolling release and I suppose the factory list is better used for debug/developpers, not for day to day use case :-) thanks jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Nope. The factory list is for both developers and users using that version.

But then I do have /home and /tmp and /boot and /srv each on separate partitions and not part of the / BtrFS. So perhaps when you make allowance for that it works out much the same. Ignore snapshots and I have 8. Remove /tmp and /boot and /srv from jdd's list and what's the difference? He has /var/lib/pgsql and /var/lib/mailman Probably because he had those apps selected. I never did. Well that seems to explain it. I _suppose_ I could create empty subbvolumes as mount point, but why?

I confirm what I have shown is simply the raw kde default install for factory (and the install went smoothly). I was just surprised when I saw the partitionning previewx in yast. I did now that btrfs is now the default filesystem, so I need badly to understand what it does :-). jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Anton,

Suppose this wasn't BtrFS. Suppose you did just tell it / /home /boot (and swap) The would you still have, on / /var and /usr and the major sub directories such as /var/tmp, /var/spool, /usr/local All of which are prime candidates for separate file systems. Well they are for me. I have /usr/share as a separate FS so as to keep down the size of my initrd and to make the backup of /usr fit on the 5G DVD. I'm sure people with ample RAm undo the suse tweek and make /tmp & /var/tmp into tmpfs While the subvolumnes are, in once sense, labels, they are also addressable as mounted file systems and can be manipulated as such with fstab & the mount command. The btrfs makes it clear that they don't have to be where they started, you can manipulate them just as you would a disk pratition. The thing about BtrFS is that it manages the whole drive or set of drives, balancing according to use and doing cool and wonderful b-tree things. OPPS! All of a sudden I have a load factor of 7 ..10 ...14 ....0.1 The best I can figure is that something-io was up at the top of top, when top could run. I *SUSPECT* this has to do with BtrFS rearranging the disk.
