Hi! Today I converted my /home from Ext4 to BTRFS by reformatting and copying all over again. I created the filesystem with -l 16384 -n 16384 -d single -m single on an logical volume Intel SSD 320 and mount with compress=lzo,spacecache. Current state: merkaba:~> btrfs filesystem show failed to read /dev/sr0 Label: ''home'' uuid: […] Total devices 1 FS bytes used 191.98GB devid 1 size 223.52GB used 193.02GB path /dev/dm-2 […] merkaba:~> btrfs filesystem df / Data: total=14.01GB, used=9.98GB System: total=4.00MB,...

Hi, I have btrfs volume, shared via samba. I have a directory of documents that I want to backup on my server. win7 reports a maximum of ~3.10MB/s transfer transferring the same directory on a ext4 samba share I get 25MB/s + Any ideas? Is it like that because of how btrfs works and is setup? Thanks, -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body

Hi! With 3.2-rc4 (probably earlier), Ext4 seems to remember what areas it trimmed: merkaba:~> fstrim -v /boot /boot: 224657408 bytes were trimmed merkaba:~> fstrim -v /boot /boot: 0 bytes were trimmed But BTRFS does not: merkaba:~> fstrim -v / /: 4431613952 bytes were trimmed merkaba:~> fstrim -v / /: 4341846016 bytes were trimmed Is it planned to add this feature to...

Hi folks, I''m using Ubuntu 12.10 Quantal with # uname -r 3.5.0-24-generic And it seems I cannot defrag : # filefrag /boot/initrd.img-3.5.0-24-generic /boot/initrd.img-3.5.0-24-generic: 3 extents found # btrfs filesystem defrag /boot/initrd.img-3.5.0-24-generic # echo $? 20 # filefrag /boot/initrd.img-3.5.0-24-generic /boot/initrd.img-3.5.0-24-generic: 3 extents found Any clue

Hallo, linux-btrfs, please delete the option "-L" (for labelling) in "mkfs.btrfs", in some configurations it doesn''t work as expected. My usual way: mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ... One call for some devices. Wenn I add the option "-L mylabel" then each device gets the same label, and therefore some other programs

Hello, I have created a btrfs filesystem with RAID1 setup having 2 disks. Everything works fine but when I try to umount the device and remount it in degraded mode, the data still goes into both the disk. ideally in degraded mode only one disk show disk activity and not the failed ones. System Config: Base OS: Slackware kernel: linux 3.3.2 "sar -pd 2 10" shows me that the data is

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, this is a new attempt to improve the output of the command "btrfs fi df". The previous attempt received a good reception. However there was no a general consensus about the wording. Moreover I still didn''t understand how btrfs was using the disks. A my first attempt was to develop a new command which shows how the disks

Hi Chris, this serie of patches updated the command "btrfs filesystem df". I update this command because it is not so easy to get the information about the disk usage from the command "fi df" and "fi show". This patch was the result of some discussions on the btrfs mailing list. Many thanks to all the contributors. From the man page (see 2nd patch): [...] The
