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

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially. This patch is developed and on top of the send/receive btrfs and btrfs-progs repo at git://github.com/ablock84/linux-btrfs.git (send-v2) git://github.com/ablock84/btrfs-progs.git (send-v2)

Hi all, Just a quick question but can''t find an obvious answer. Can I create/convert a existing (btrfs) directory into a subvolume? It would be very helpful when transferring ''partitions'' into btrfs. I found a similar question way back in google, but that site is down now generally. Thanks in advance. -- To unsubscribe from this list: send the line

Hi, I''ve created snapper packages for Ubuntu, available on https://launchpad.net/~snapper/+archive/stable. For those new to snapper, it''s a tool for managing btrfs snapshots (http://en.opensuse.org/Portal:Snapper). It depends on libblocxx available from https://launchpad.net/~bjoern-esser-n/+archive/blocxx , and currently uses git source up to commit 50dec40. I''ve done

Hello, We''re a team of 4 final year computer science students and are working on generating a diff between file system snapshots using the send receive code. The output of our utility looks like this- (I''ve tested it on a small subvol with minimal changes just to give an idea) root@nafisa-M-6319:/mnt/btrfs# btrfs sub diff -p /mnt/btrfs/snap1 /mnt/btrfs/snap2

Hi guys, After having received strong advice from the people in this list to upgrade my kernel to the latest one, I have installed 3.8.0-14-generic #24-Ubuntu SMP x86_64 on several (4) machines. In the hope of improving systems speed I had also removed all snapshots then defragged the FSes - the snapshots have been recreated since, as I use the excellent SuSE "Snapper" tool. But well,

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

Hi, I have 4 machines, all converted to BTRFS about 6 months ago, now all running Ubuntu Quantal with kernel 3.5.0-17 The matter is that all these machines are now getting slower and slower everyday, every disk access causing the disk to be 100% busy for long periods, to the point that I''m now seriously considering migrating everything back to ext4...

We should avoid using non multi-path (mp) path for mp disks As of now there is no good way (like api) to check that. A workaround way is to check if the O_EXCL open is unsuccessful. This is safe since otherwise the BTRFS_IOC_SCAN_DEV ioctl would fail if the disk-path can not be opened with the flag O_EXCL set. This patch also includes some (error) print format changes related to the btrfs

Sorry Hughes, got some questions. I have the feeling that I do a lot wrong. Today I sent a mailing post at fedora where it is also about btrfs under fedora. In time when i write the mail i forward it my patch for fedora 25 pretransaction & snapper.yp, with the hope of feedback. https://lists.fedoraproject.org/archives/list/devel at lists.fedoraproject

Sorry for all the newbie questions. I really appreciate everyone's help today. Okay I've got outgoing and incoming calls working with no echo. yay! Now I'm having an issue with SIP extension to extension calling. Any time I dial another extension it goes right into voice mail. My extensions.conf is pretty small and rough but, here's what I have right now. Most of it was taken
