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 noticed we were getting lots of warnings with xfstest 83 because we have reservations outstanding. This is because we moved the orphan add outside of the truncate, but we don''t actually cleanup our reservation if something fails. This fixes the problem and I no longer see warnings.

Hello, I have an IVR with Intel HMP SIP stack, which is a peer behind my Asterisk box (Asterisk 1.0.7, Digium PRI). When dialing in via PSTN, there are klicking sounds in the background, which do not appear, when dialing in via SIP (using Asterisk as pbx). The issue does not seem to be an alaw/?law problem. I tried trunking two Asterisk boxes via IAX and then call via two asterisks, but the

When a directory has a default ACL and a subdirectory is created under that directory, btrfs_init_acl() is called when the subdirectory''s inode is created to initialize the inode''s ACL (inherited from the parent directory) but it was clearing the ACL from the inode after setting it if posix_acl_create() returned success, instead of clearing it only if it returned an error. To

Hello, I would like to have a central LDAP-Server in my main office and a replicated one in my satellite office, connected via VPN. Then I want my SAMBA-PDC in the satellite to use the local LDAP. I think this should end in: READ ---- Samba <-> Replicate WRITE ----- Samba -> Replicate <-referrer- Samba <-> Central

Hi Everyone, We are thinking of venturing into the world of hosting Windows DomUs on our Xen infrastructure. As Windows generally requires a lot more IOPS than Linux does, we are trying to do everything we can to improve performance. While using SSDs would solve the IOPS problem, SSDs suffer from limited write cycles. So, we have the idea of using Flashcache from Facebook to use a single SSD as

Hello, I would like to migrate my user-accounts from a Samba 2 to a Samba 3 setup. Old Setup: Samba 2 with PAM support. PAM uses LDAP to store PosixAccounts New Setup: Samba 3 with "native" LDAP. PosixAccounts are already migrated to my new LDAP server. I tried pdbedit with my old smbpasswd file: ---snip--- # pdbedit -i smbpasswd:./smbpasswd build_sam_account: smbpasswd database

I would like to fit a hierarchical regression model from Witte et al. (1994; see reference below). It's a logistic regression of a health outcome on quntities of food intake; the linear predictor has the form, X*beta + W*gamma, where X is a matrix of consumption of 82 foods (i.e., the rows of X represent people in the study, the columns represent different foods, and X_ij is the amount of

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?

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I''ve been unable to find anything definitive about what happens if I use RAID0 to join an SSD and HDD together with respect to performance (latency, throughput). The future is obvious (hot data tracking, using most appropriate device for the data, data migration). In my specific case I have a 250GB SSD and a 500GB HDD, and about 250GB of

Hi all! I want to use 'acl group control' setting to delegate privileges to specific administrators. Unfortunately, I'm unable to set the primary group using windows file permissions dialog, I can only add and remove ACL groups. I tried to do this by removing all groups but one from Windows. This doesn't work: the primary group has all privs removed and the extra group is

It''s been nearly a year since the patches needed to implement a reflinked copy between subvolumes have been posted (http://permalink.gmane.org/gmane.comp.file-systems.btrfs/9865 ) and I still get "Invalid cross-device link" error with Linux 3.2.4 while I try to do a cp --reflink between subvolumes. This is a *very* useful feature to have (think offline file-level

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.

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
