Hi, the $subj warning appears sometimes in syslog, in my case when xfstests/209 runs looped. The minimal reproducer is looped mkfs+mount. The message comes from disk-io.c btree_readpage_end_io_hook(): 581 if (check_tree_block_fsid(root, eb)) { 582 printk_ratelimited(KERN_INFO "btrfs bad fsid on block %llu\n", 583 (unsigned long

A while ago someone on IRC had a directory with no entries but with a non-zero i_size. rmdir fails because i_size isn''t zero but there are no items left to remove and decrease i_size. At the time casual code inspection implied that this would be possible in unlucky error cases. I finally got around to really reading up and reproducing it. diff --git a/fs/btrfs/inode.c

Currently the fs sync function (super.c:btrfs_sync_fs()) doesn''t wait for delayed work to finish before returning success to the caller. This change fixes this, ensuring that there''s no data loss if a power failure happens right after fs sync returns success to the caller and before the next commit happens. Steps to reproduce the data loss issue: $ mkfs.btrfs -f /dev/sdb3 $

When making btrfs filesystem. we firstly write root leaf to specified filed, and then we recow the root. If we don''t recow, some trees are not in the correct block group.

Hi! I used to have arch linux running on 1 btrfs partition (sda1, incl. /boot). When switching to 3.2.5 recently the system fails to boot: (after udevd) /etc/rc.sysinit: line 15: 117 Bus error mountpoint -q /proc and so on, no idea. It used to boot with 3.2.4, but 1) I obviously had some corruption in the tree, when I tried to delete a certain file I hit e.g. "kernel BUG at

Hello everyone! I'm a newcomer for the great LLVM project. I've started to explore the source code of LLVM project to become more familiar with it, and I've found some strange usage of move semantics in constructor of StringMapImpl( StringMapImpl &&RHS) {...} class in include/llvm/ADT/StringMap.h line 56. Could anyone explain me the purpose of zeroing of all fields of RHS in

I have accidently damaged the first block(s) of a btrfs partition and can''t mount it anymore.

This patch adds mixed back ref support for btrfs programs. The mixed back ref is a new disk format. back compatilibity is still not implemented. To try the new disk format, you need fresh formatted btrfs.

We discussed using the top bits of the chunk type field field to store a number of redundant disks -- so instead of RAID5, RAID6, etc., we end up with a single ''RAID56'' flag, and the amount of redundancy is stored elsewhere. This attempts it, but I hate it and don''t really want to do it. The type field is designed as a bitmask, and _used_ as a bitmask in a number of
