similar to: [PATCH] Btrfs: allow running defrag in parallel to administrative tasks

Now with the below kernel patch, the excl operations like dev add/replace/resize and balance returns the btrfs error code defined in btrfs.h, this patch will help btrfs-progs (and thus user) to know the error string on the terminal (instead of /var/log/messages as previously kernel did). This patch depends on the btrfs kernel patch: btrfs: return btrfs error code for dev excl ops err

I ran into a panic while running find -xdev | xargs brtfs fi defrag ''{}''. I don''t remember the exact command because the history was not saved. I also started and stopped it a few times however. The kernel logs were on a different filesystem. Here is the kern.log:http://fpaste.org/9383/36729191/ My setup is two 2TB hard drives in raid 1. They are both sata drives so

From: Ajesh JS <ajesh.js@hp.com> This patch provides a mechanism to modify the permission of a subvolume in a btrfs file system This helps to apply a policy of having read-write subvolume inside a read-only subvolume. One use case is to have the whole root file system as a read-only subvolume and have /etc as a read-write subvolume inside. Signed-off-by: Ajesh JS <ajesh.js@hp.com>

From: Anand Jain <anand.jain@oracle.com> (This patch is for the review/test not yet for the integration). Here is an implementation of the feature to add label to the subvolume and snapshots. Which would help sysadmin to better manager the subvol and snapshots. This can be done in two ways, one - using attr which is user land only changes but drawback is able to change the label

Hi, The following series of patches implements in btrfs an ioctl to do out-of-band deduplication of file extents. To be clear, this means that the file system is mounted and running, but the dedupe is not done during file writes, but after the fact when some userspace software initiates a dedupe. The primary patch is loosely based off of one sent by Josef Bacik back in January, 2011.

The kernel side for rescan, which is needed if you want to enable qgroup tracking on a non-empty volume. The first patch splits btrfs_qgroup_account_ref into readable ans reusable units. The second patch adds the rescan implementation (refer to its commit message for a description of the algorithm). The third patch starts an automatic rescan when qgroups are enabled. It is only separated to

I noticed a few days ago that btrfs fi defrag -cXXX can not be used to compress files unless they are fragmented. The attached patch passes the compression flag to should_defrag_range, where it disables the adjacent-extent and extent size checks if set. The inline/sparse extent check is not modified - I assumed it would not be useful to compress inline extents. -- Andrew Mahone andrew DOT mahone

--=-mIogSkSG8HjWN56JSL46 Content-Type: text/plain Content-Transfer-Encoding: quoted-printable Tom, If you have connection tracking enabled, then you have auto-magically ordered all packets to be defragged is that correct? I wonder if there is any noticible latency, especially in on-line games with defragging packets. Are there any ways to make an exception - to avoid tracking certain
