Hello I think, I somewhat destroyed my btrfs filesystem on my Ubuntu 13.04 kernel 3.8.0-25-lowlatency system. It got destroyed, because the system was hanging for some other reason and I had to remove power... When I try to mount my filesystem (there''s only one, with a few subfilesystems), the system crashes. Also btrfsck dies; always like this: a@ask-home:~$ sudo

Hiya, Recently, a btrfs file system of mine started to behave very poorly with some btrfs kernel tasks taking 100% of CPU time. # btrfs fi show /dev/sdb Label: none uuid: b3ce8b16-970e-4ba8-b9d2-4c7de270d0f1 Total devices 3 FS bytes used 4.25TB devid 2 size 2.73TB used 1.52TB path /dev/sdc devid 1 size 2.70TB used 1.49TB path /dev/sda4 devid 3 size

hi: I want to setup a small samba4 server with AD and file server function. I know that samba4 AD DC has no netbios browsing support. are there other missing functions, like winbindd or something else? and if I install two samba4 instance, one to "/usr/local/samba"(for file server), one to "/usr/local/samba-ad"(for AD DC). and give them two seprate ip to bind. will it

Hi, I use btrfs for my /home drive. It''s a separate drive with just a single partition. I upgraded to ubuntu 13.10 (beta) a few weeks ago, without any real trouble. But I did have too many issues (not with the drive or btrfs, though) so I decided to do a fresh install. The new install failed a few times, so I made another startup usb drive with another program and that one worked fine.

I''m using Btrfs v0.20-rc1-253-g7854c8b on kernel 3.10.10-1-ARCH. I''ve been using this btrfs filesystem on an SSD for a little under a year with no problems until now. I noticed it was getting a bit full (~79%) and tried to do some cleanup by removing old snapshots. Immediately after, the filesystem went into read only mode. I then followed Hugo Mill''s advice (that was

Hi I have been running 4 nodes in a distributed,replicated setup on gluster 3.3.1 since January. Each node has 10tb of storage to give a total of 20tb, for 2-3 years before that they were running on previous versions of gluster. Recently we had issues with the backend storage (ext4) on one of the nodes going read only, thats now resolved and I have ran the following and had errors. gluster

Hi, My company is testing btrfs (kernel 2.6.38) on a slave MySQL database server with a 195Gb filesystem (of which about 123Gb is used). So far, we''re quite impressed with the performance. Our database loads are high, and if filesystem performance wasn''t good, MySQL replication wouldn''t be able to keep up and the slave latency would begin to climb. This though, is

Greetings! I''m testing raid6, and recently added two drives. I haven''t been able to properly resume a balance operation: the number of total chunks is always too low. It seems that the balance starts and pauses properly, but always resumes with ~7 chunks. Here''s an example: vendikar tim # uname -r 3.10.0-031000rc4-generic vendikar tim # btrfs fi sho Label:

Hello, on a fs with 4 disks, raid 10 for data, one drive was failing and has been removed.

Hello everyone. After all the problems I had demoting my DC and managed it to work again, it was working for only a week.

Hallo, "never change a running system" ... For some months I run btrfs unter kernel 3.2.5 and 3.2.9, without problems. Yesterday I compiled kernel 3.3.4, and this morning I started the machine with this kernel. There may be some ugly problems. Copying something into the btrfs "directory" worked well for some files, and then I got error messages (I''ve not

Hallo, linux-btrfs, First I create an array of 2 disks with mkfs.btrfs -d raid0 -m raid1 /dev/sdb1 /dev/sdd1 and mount it at /srv/MM. Then I fill it with about 1,6 TByte. And then I add /dev/sde1 via btrfs device add /dev/sde1 /srv/MM btrfs filesystem balance /srv/MM (it run about 20 hours) Then I work on it, copy some new files, delete some old files - all works well. Only df

Hi. I''m considering an imminent switch from ext4 to btrfs and I''m hoping that someone can lend me advice before I do something unsupported. I have a software raid 6 array configured via mdadm. It was sitting at 8 x 3TB until I recently doubled that, grew the array and found that ext4 doesn''t want to resize. So, I''m looking to: 1. convert from ext4 to btrfs

Hello, today I wanted to remove one drive from raid1, and people at #btrfs advised me to use ''-dconvert=single'' before ''btrfs device delete''. I thought of adding ''-mconvert=dup'' too, but the kernel does not let me do that. It looks like ''dup'' is disallowed for an array of multiple devices. So, to go back to a single-drive

I am trying to write a "thumbnailer" for the thunar file manager that can process .ogg files containing a video stream and produce a thumbnail of a particular frame. The only trouble is telling which files have a video stream in an efficient method. The best I've come up with is running ogginfo on every file with the mimetype application/ogg. Is there a better method? I know

Hello, I habe the problems described in here https://btrfs.wiki.kernel.org/index.php/Gotchas: Files with a lot of random writes can become heavily fragmented (10000+ extents) causing trashing on HDDs and excessive multi-second spikes of CPU load on systems with an SSD or large amount a RAM. On servers and workstations this affects databases and virtual machine images. The nodatacow mount option
