Great idea for an article Jdd :D
thanks. I have always ideas to give work to others - but usually I try not to write them :-(
Maybe you can throw some questions, then I willl throw some more and
May be we can go practical. What happen when you want to install a fresh 13.2... * you get a nice screen (yast install, I guess) a bit simpler than we are used to * when partitionning is the subject, you are offered to use BTRFS on /, with a lot of subvolumes. This was never the case before, so even an experienced user my wonder. Specially when installing on somebody else computer, what I do nearly constantly. What is I have to change a bit the defaults? There are no subvolumes on /home, I did not investigate what was the /home partition existed already (and was not formatted by the install, good) I understand these subvolumes are dynamic (=expandables/shrinkables) locations, but what is the use of having them in the first place? Noticed the / was hudge, 40Gb when usually only 20Gb was used (and my test disk is only 240Gb). Guess it is for snapshots. I'm used of VirtualBox snapshots, is that the same? after the install ends, found a new yast menu: snapper. Ah! found interesting doc http://doc.opensuse.org/products/draft/SLES/SLES-admin_sd_draft/cha.snapper.... oh! yes: "As a rule of thumb you should consider using twice the size than you normally would" "Apart from the YaST and zypper snapshots, Snapper creates hourly snapshots of the system partition (/)" this page have to be printed! this may explain my initial question: " For some directories we decided to disable snapshotting, e.g. /var/log since reverting logs makes searching for problems difficult. To exclude a path from snapshotting we create a subvolume for that path. The following mount points are excluded from snapshotting on SUSE Linux Enterprise Server: /opt /srv /tmp /var/crash /var/log /var/run /var/spool /var/tmp " buthis doc is draftn les and seems old. also founnd is http://events.linuxfoundation.org/sites/events/files/slides/EndUserSummit_20... http://www.novell.com/feeds/nih/wp-content/uploads/2012/05/SUS18_lab.pdf (not read yet) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
