I am using NFS over brtfs (vanilla 3.8.5) for heavy CoW to clone virtual disks with sizes 20-50GB. It worked OK for a couple of days, but yesterday it crashed. Reboot fixed the problem and I do not see any data corruption. I have a couple of different kdumps, I will include one as text and attach the other ones. I am using Fedora 18 with vanilla 3.8.5. The filesystem is created over a SAN volume

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. I see this at top: 1182 root 20 0 0 0 0 R 100.0 0.0 16:39.73 [btrfs-delalloc-] And LA is grow. What is this and how can I fix it? -- Best regards, Proskurin Kirill -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of

...ns are delayed-write instructions." The Y-register is a state-register. Furthermore in the B.29-secion there is a programming note saying: MULScc, RDY, SDIV, SDIVcc, UDIV, and UDIVcc implicitly read the Y register. If any of these instructions execute within three instructions after a WRY which changed the contents of the Y register, its results are undefined. This currently is not respected with LLVM. I'm using 3.9 and checked whether any commit on the master-branch handles this case, I haven't seen anything - but I might be wrong. Unfortunately I'm not (yet) quali...

While untar''ing an image to an sd card via a reader, I got the following bug. The system also has a btrfs root, and a whole swath of processes went into uninterruptable sleep. I was able to poke around via ssh and sysrq, and already had netconsole set up to capture the bug. Root fs is on /dev/sdi1, and /dev/sdj2 is the card reader which was the target of the untar.

Hi all, Last week we had 2 times an "uncorrectable ecc memory error" crash on our server on the same memory module. After removing the faulty module and restarting the server, everything was working again. However, yesterday we had a soft lockup and had to restart the server again. No warning or ecc error this time. Everything is working now, but we want to avoid this in the future

I subscribed to report a bug. if I rsync a directory from a PC (invoked on the PC) to a unix server through ssh, the first time all works fine, then if I do it again and there are no copys it crashes on the PC. If I touch one file on the PC so it copys at least one file then all is OK. I have the latest cygwin installed on a PC with freshly installed win2000 build 5.00.2195, and the latest

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

Currently, I load the RData file then ls() and str(). But loading the file takes too long if the file is big. Most of the time, I only interested what the variables are in the the file and the attributes of the variables (like if it is a data.frame, matrix, what are the colnames/rownames, etc.) I'm wondering if there is any facility in R to help me avoid loading the whole file.

I''ve upgraded to linux 3.10 and enabled extended inode refs and skinny metadata extent refs with these commands: btrfstune -r /dev/sdc1 btrfstune -x /dev/sdc1 Since then, I have "WARNING: at fs/btrfs/backref.c:903 find_parent_nodes+0x616/0x815 [btrfs]()" showing up like crazy: # grep -c "WARNING: at fs/btrfs/backref.c:903" syslog 181819 That''s after just

Miao, I was trying out your patch on scalability testing for BTRFS on v3.3 kernel. http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg14930.html However, I ran into a lot of warnings (see the dmesg below). Wonder if you have a more up to date version of this patch? In addition, I have to do this modification to fix a warning in your original patch. diff --git a/fs/btrfs/inode.c

This is a small/trivial patch to get HURD to _compile_ (I haven't gotten PRNG to work yet) openssh. All it does is define MAXHOSTNAMELEN in defines.h if it isn't already defined (there may need to be a library loaded first, or you may want to incorporate that patch into canohost.c instead of defines.h). Anyway, small patch for canohost.c and defines.h because HURD doesn't use

Hello, I'm using Samba version 1.9.18p10. I am trying to backup a Win95 disk with smbtar, but it skips lots of files without any apparant reason.

Hi, I''ve been running btrfs on one of my machines for a few months now but I keep hitting performance issues. My system quite frequently freezes due to IO starvation. Looking at iotop it tends to show the large majority of the disk I/O being taken up with various btrfs tasks peeking at 7-8M/s, namely: btrfs-endio-wri btrfs-delayed-m btrfs-transacti btrfs-cleaner
