...; you are interested in, then please let us know. I was thinking of running some operations on the root filesystem by kexec-rebooting into an appliance to get exclusive access. I would like to do something like that for my blocks tool (which does conversions to LVM and bcache). https://github.com/g2p/blocks#readme

...or this application currently, will these patches address the problem and read-only snapshots could be deduplicated? Or are read-only snapshots meant to be what the name suggests: Immutable, even for deduplication?

...that understanding correct? Will compressed blocks among many files also be deduplicated? * How exactly do the recently merged offline deduplication features in the kernel interfere with what was (in my limited understanding) already possible with userspace tools like <https://github.com/g2p/bedup>? Are such third-party tools likely to be integrated into btrfs-progs? Are they supposed to be kept separate? * Does this change the on-disk format? Putting it another way, will it be safe to possibly go back to a previous kernel, if there is some problem with the current kernels...

According to https://github.com/g2p/bedup/tree/wip/dedup-syscall "The clone call is considered a write operation and won''t work on read-only snapshots." Is this fixed on newer kernels? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.ke...

Hello, I have a filesystem that has become unusable because of a balance I can''t stop. It is very close to full, and the balance is preventing me from growing it. It was started like this: sudo btrfs filesystem balance start -v -musage=60 -dusage=60 /srv/backups It has been stuck at 0% across reboots and kernel upgrades (currently on 3.8.1), and cancelling it had no effect: Balance

Hi. I'm trying to get OTRS running on CentOS 5.5 with SELinux enabled, and audit.log / audit2allow tell me I need to add the local policy: #============= httpd_t ============== allow httpd_t unconfined_t:shm { unix_read unix_write }; which I think will allow the httpd access to read and write from shared memory? Is that right? What are the risks involved in opening this? I notice it is

Hello, As I understand it guestfs appliances normally work as servers and run high-level commands from some external channel. But it might be possible to bundle a guestfish script to run commands from and do away with the external system. That would make it useful on non-virtualised systems. Has anyone tried this already?

...ioctl. It can be compiled completely seperately from the rest of the project via "make btrfs-extent-same". This makes direct testing of the ioctl more convenient. Gabriel de Perthuis also has a bedup branch which works against this ioctl. The branch can be found at: https://github.com/g2p/bedup/tree/wip/dedup-syscall Limitations We can''t yet dedupe within the same file (that is, source and destination are the same inode). This is due to a limitation in btrfs_clone(). Code review is very much appreciated. Thanks, --Mark ChangeLog All of this rounds fixes are th...

Welcome, I''ve been using btrfs for over a 3 months to store my personal data on my NAS server. Almost all interactions with files on the server are done using unison synchronizer. After another use of bedup (https://github.com/g2p/bedup) on my btrfs volume I experienced huge perfomance loss with synchronization. It now takes over 3 hours what have taken only 15 minutes! File browsing is not affected; but it takes forever to read contents of the files! When I use `iotop -o -d 30` (which measures I/O activity for 30-second...

v3: - Don't remove the LVM transform.

v2 of previous patch, which fixes some missing bits. For now I'm going to go with Pino's RHEL 7.1 patch, since it is at least smaller than this. So I'm sending this to the list just to have it archived for later. Rich.

Hello If I want to manage a complete disk with btrfs, what''s the "Best Practice"? Would it be best to create the btrfs filesystem on "/dev/sdb", or would it be better to create just one partition from start to end and then do "mkfs.btrfs /dev/sdb1"? Would the same recomendation hold true, if we''re talking about huge disks, like 4TB or so?

Simplify how we handle lvm.conf.

Hi, newer lvm2 releases don't have have uncommented "filter" lines, so the current way to edit lvm.conf doesn't work anymore. Instead, switch to augeas (with a "custom" len) for a cleaner and working way to set the lvm filter.

Augeas 1.7.0 was released a couple of days ago. By encouraging everyone to upgrade to this we can drop several calls to aug_transform and also our custom copies of two lenses, and a lot of related code. Rich.
