This ends up crippling LICM in particular, and GVN to a lessor degree. The approach I've been playing with would create this loop structure: goto inner while (true) { outer: helper(); inner: while( some_condition ) //do lots of work here if (!some_rare_condition) { <-- This is loop variant goto outer; } } } (Excuse...

First off, thanks for an awesome file system, it is working well for my purposes of compressing a filesystem on a small VPS. Woot! I thought I''d call out a few things (in the hopes of spurring improvements) I''d seen about btrfs (in case they weren''t common knowledge...):

...ls to implement this, I am happy to use 3rd party proprietary stuff if necessary. * Long(er) Version* Current Situation.. I have a client with many (200x) CentOS 5.x servers deployed in various web, mail, database and file server roles, and these boxes have been variously administrated to a lessor or greater degree. All the boxes have EPEL repository included as part of their base-install, and all boxes have cron jobs for "yum -y update" running frequently, and are rebooted when kernels are available. (so they are not in a terrible state) For network, local and external vulne...

Hello, We are using btrfs filesystems in our infrastructure and, at some point of time, they start refusing to create new subvolumes. Each file system is being quota initialized immediately after its creation (with "btrfs quota enable") and then all subfolders under the root directory are created as subvolumes (btrfs subvolume create). Over time, these subvolumes may also be

I thought I would try btrfs on a new installation of f14. yes, I know its experimental but stable so it seemed to be a good time to try it. I am not sure if I have missed something out of all my searching but am I correct in thinking that currently: I. it is not possible to boot from a snapshot of the operating system and, in particular, the yum snapshots cannot be used for
