search for: check_int

...generic. The search term in the kernel log that can be used to filter on the existence of detected integrity issues is "btrfs: attempt". The integrity check is enabled via mount options. These mount options are only supported if the integrity check tool is compiled by defining BTRFS_FS_CHECK_INTEGRITY. Example #1, apply integrity checks to all metadata: mount /dev/sdb1 /mnt -o check_int Example #2, apply integrity checks to all metadata and to data extents: mount /dev/sdb1 /mnt -o check_int_data Example #3, apply integrity checks to all metadata and dump the tree that the super block re...

Hi Linus, My for-linus branch has a one line fix: git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus Sage hit a deadlock with ceph on btrfs, and Josef tracked it down to a regression in our initial rc1 pull. When doing nocow writes we were sometimes starting a transaction with locks held. Josef Bacik (1) commits (+1/-0): Btrfs: release path before starting
