Hello everyone, Yan Zheng sent along an update for the new format patch today, and it slightly changed the disk format for backrefs used when balancing space across drives. We decided against supporting an intermediate format that was only a week old, and his update makes a few important features much much easier (snapshot deletion for one). If you''ve tried the newformat branch and run

Heyho! (This is using btrfs from Debian''s 2.6.32 2.6.32-3-kirkwood kernel (-9 package; btrfs tools is v0.19-16-g075587c) A few observations about btrfsck: a btrfsck run on a 2T volume (4 disks) on a QNAP appliance (512M ram) got killed by Mr. OOM Killer. Initially, I was quite surprised. I''m only moderately surprised now since it might well be that I forgot to enable

Hi. I got following BUG trace. This is violation of BUG_ON(!buffer_locked(bh)) check on submit_bh() function. In write_dev_supers(), if wait parameter is set and buffer_uptodate() check is negative, submit_bh() is executed and hit above BUG_ON. So I fixed this issue. Thanks.

Hi everybody, I am using btrfs as my main fs for some time now, but I am experiencing severe performance drawbacks. I can''t qualify the circumstances, but sometimes during disc access the whole system freezes for some time. Maybe somebody could suggest some general things I could try to search for the problem? Thanks in advance, Florian --- Some background information: $ mount |

Hello list, recently reformatted my home partition from XFS to RAID1 btrfs. I used the default options to mkfs.btrfs except for enabling raid1 for data as well as metadata. Filesystem is made up of two 1TB drives. mike@mercury (0) pts/3 ~ $ sudo btrfs filesystem show Label: none uuid: f08a8896-e03e-4064-9b94-9342fb547e47 Total devices 2 FS bytes used 888.06GB devid 1 size 931.51GB used

I''ve run a little wired benchmark on comparing Btrfs v0.19 and XFS: There are 2000 directories and each directory contains 1000 files. The workload randomly stat a file or chmod a file for 2000000 times. And the number of stat and chmod are 50% and 50%. I monitor the number of disk read requests #Disk Write Requests, #Disk Read Requests, #Disk Write Sectors, #Disk Read

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

I''ve just confirmed this test failure by building and running coreutils'' "make check" on a btrfs file system I''d just created using mkfs.btrfs v0.19 on Fedora

I have accidently damaged the first block(s) of a btrfs partition and can''t mount it anymore. I can see that my data is still intact by running a command like: cat /dev/sda5 | hexdump -C | more Do any (experimental) tools exist which would allow me to recover the files?
