The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct

The new xfstests will run fsck against the volume to make sure we didn''t introduce any inconsistencies, which is nice except we will error out immediately if we mount with inode_cache. We need to make btrfsck skip the special free space cache items and then just assume that we have a link for the free space cache inode item. This makes btrfsck pass with success on a fs with inode cache items. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com> --- btrfsck.c | 7 +...

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please

Hi all, Change from v1 to v2: bug fix and metadata/credits reservation improvement. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink.

Hi all, i am new on btrfs, i am testing KVM on btrfs (host: kernel x86-64 3.5.3), the performance is reasonable. I have two question on defrag, can someone help me? 1. According to btrfs wiki, defragment a COW file will produce two unrelated files. Does it apply to the "autodefrag" mount option? 2. Is there any command for the fragmentation status of a file/dir ? e.g. fragment

I use it for backups: rsync the whole system to a subvolume, snapshot it and then delete some tempfiles in the snapshot, which are 90% of the full-backup, all once a day. In figures: on this 1 TB hdd is the full-backup with around 600 GiB and 10 to 20 snapshots with around 30 GiB each, all t...
