Hi, I am using 2.6.36.3 kernel with btrfs, 512MB memory and a very slow disk, no special options for mounting btrfs except noatime. Now I found it very slow. When I rm a 5GB movie, it took 20 secs. -- 竹密岂妨流水过 山高哪阻野云飞 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at

Hi, I''m trying to convert two ext4 FS to btrfs, but I''m surprised by the time needed to do that conversion. The first FS is on a 500GiB block device, and btrfs-convert is running since more than 48h : root 1978 25.6 47.7 748308 732556 ?

I know this question was asked, oh, a year ago, and the answer was "No." But I''m wondering if anything''s changed in the interim. Specifically, shy of "dd", is there any way to back up the files and metadata on a btrfs partition?

...e still useful. On second thought: it won''t make it exactly file-level granular, if we introduce snapshots in the mix, the new version can have the data regularly accessed while the old snapshot won''t, this way the obsolete blocks can be moved to slow storage. -- Hubert Kario QBS - Quality Business Software 02-656 Warszawa, ul.

I realise that the hard link limit is in the queue to fix, and I read the recent thread as well as the older (october I think) thread. I just wanted to note that BackupPC *does* in fact run into the hard link limit, and its due to the dpkg configuration scripts. BackupPC hard links files with the same content together by scanning new files and linking them together, whether or not they started

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

What happened to the hot data tracking feature in btrfs? There are a lot of old patches from aug 2010, but it looks like the feature has been completly removed from the current version of btrfs. Is this feature still on the roadmap?

What are the recommendations for running KVM images on BTRFS systems using kernel 3.4?  I saw older posts on the web complaining about poor performance, but I know a lot of work has gone into btrfs since then.  There also seemed to be the nocow option, but I didn''t find anything that said it actualy helped. Anybody have ideas? Thanks, Matt -- To unsubscribe from this list: send the line

Glück Auf! I know its been discussed more then ones, but as a user I really would like to see the patch for allowing this in the kernel. Some users tested this patch successfully for weeks or months in 2 or 3 kernel versions since then, true? I''d say by creating a snapshot, it''s nothing else in the end. More then one file or tree sharing the same data on disc, or am I wrong?

Hello all. What we have: SL6 - kernel 2.6.32-131.2.1.el6.x86_64 btrfs on mdadm RAID5 with 8 HDD - 27T partition.

Hi, I''ve been looking at Btrfs and have a couple of naive questions that don''t seem to be answered on the wiki or in the articles I''ve read on the filesystem. First: discovering a file''s checksum value. Here''s the scenario: software is writing some data as a fresh file. This software happens to know (a priori) the checksum of this data; for

I''m looking to try BTRFS on a SSD, and I would like to know what SSD optimizations it applies. Is there a comprehensive list of what ssd mount option does? How are the blocks and metadata arranged? Are there options available comparable to ext2/ext3 to help reduce wear and improve performance? Specifically, on ext2 (journal means more writes, so I don''t use ext3 on SSDs,
