similar to: [PATCH v4 0/3] Btrfs: quota rescan for 3.10

This is a first draft of a subvolume quota implementation. It is possible to limit subvolumes and any group of subvolumes and also to track the amount of space that will get freed when deleting snapshots. The current version is functionally incomplete, with the main missing feature being the initial scan and rescan of an existing filesystem. I put some effort into writing an introduction into

Hi, I needed to logrotate a fil named qmail-queue.log from qmail-scanner. So i've edit /etc/syslog.conf and changed it to: *.info;qmail-queue.none;auth.none;mail.none;authpriv.none;cron.none /var/log/messages (...) # qmail-queue logs qmail-queue /var/spool/qscan/qmail-queue.log Also, i've edit /etc/logrotate.d/syslog and changed to /var/log/messages

I''m trying to use this feature of qgroup: btrfs qgroup assign <srcid> <destid> <path> Assigns the lower level qgroup src to the higher level qgroup dest in the btrfs found in <path>. It is used to build qgroup hierarchies. However, I fail to understand how this feature should work, and I''m getting "ERROR: bad relation requested":

btrfs-prog commit: 58a39524619f38d193b8adc3d57888ec07b612aa change the default output to binary prefix, and introduced a new option '--raw' to keep the traditional behaviour. This patch will add a check function to determine whether to add '--raw' option to 'btrfs show qgroup'. Signed-off-by: Chen Hanxiao <chenhanxiao@cn.fujitsu.com> --- daemon/btrfs.c | 33

Hi, This series adds support to btrfs qgroup related commands, inclduing quota commands, and two leftover of subvolume commands. Regards, Hu Hu Tao (8): New API: btrfs_subvolume_get_default New API: btrfs_subvolume_show New API: btrfs_quota_enable New API: btrfs_quota_disable New API: btrfs_quota_rescan New API: btrfs_qgroup_limit New API: btrfs_qgroup_create New API:

Hi, This is v3 series to add support to btrfs qgroup related commands, inclduing quota commands, and two leftover of subvolume commands. Regards, Hu changes: v3: - don't intialize fs_buf (patch 1) - check the return value of sysroot_path (patch 1) - check fs_buf rather than fs (patch 1) - fprintf (stderr,...) -> reply_with_error() v2: - add tests for new APIs - combine

Hi, This is v2 series to add support to btrfs qgroup related commands, inclduing quota commands, and two leftover of subvolume commands. Regards, Hu changes: v2: - add tests for new APIs - combine btrfs_quota_enable and btrfs_quota_disable - following APIs changed to operate on Mountable_or_Path: btrfs_subvolume_get_default, btrfs_quota_enable, btrfs_quota_rescan. Hu Tao (11):

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

When data in a file is overwritten, starting somewhere in the middle of the file, the overwritten space is counted twice against the space usage numbers. Is this a bug, or did I something wrong? This is what I did: I create a subvolume and limit it to 4 MB, and create a 1000 KB file in the subvol: # btrfs subvol create s Create subvolume ''./s'' # btrfs

Hi gang, I was a little surprised to see that patch go by recently which fixed an endian bug. I went to see how sparse checking looked and it was.. broken. I got it going again in my Fedora environment. Most of the patches are just cleanups, but there *were* three real bugs lurking in all that sparse warning spam. So I maintain that it''s worth our time to keep it going and fix

Not sure if it''s anything interesting - I had the following entry in dmesg a few days ago, on a server with 32 GB RAM. The system is still working fine.

'btrfs qgroup show' used to output bytes in raw, but in btrfs-progs v3.18.2 it outputs bytes with suffix KiB, MiB or like by default, which causes error when parsing the output. Fix it by adding '--raw' to let 'btrfs qgroup show' output raw numbers always. Signed-off-by: Hu Tao <hutao@cn.fujitsu.com> --- daemon/btrfs.c | 4 ++++ 1 file changed, 4 insertions(+)

As Pino's comment, we should take advantage of macro CLEANUP_FREE_STRING_LIST v4: remove some redundant strdup v3: fix test case failure v2: properly initialize lines Chen Hanxiao (3): do_btrfs_qgroup_show: fix a bad return value do_btrfs_subvolume_list: fix a bad return value btrfs: use CLEANUP_FREE_STRING_LIST for list free daemon/btrfs.c | 70

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, This is the part1 of improving btrfs support. This series adds missing parameters to btrfs_subvolume_snapshot and btrfs_subvolume_create, and adds two new API btrfs_subvolume_get_default and btrfs_subvolume_show. Other parts will follow. Regards, Hu Hu Tao (6): btrfs: correct words about subvolume and snapshot btrfs: add optional parameter `ro' to btrfs_subvolume_snapshot btrfs:
