All callers of robust_rename() call copy_file() if EXDEV is received. This patch moves the copy_file() call into robust_rename().

All error codes are just made-up return codes to give proper error messages in the pager. Also update the HAP related error message now that paging is enabled also on AMD hosts.

...ot across directory boundaries. This is the same behavior when you try to rename across regular partition boundaries, as a hardlink will fail. I understand that renaming was changed a while back so it would not be racy, but is there any reason it shouldn't fall back to a racy rename if EXDEV is returned? I know currently that if LINK_OPNOTSUPP_ERRNO is returned, we'll try a racy rename. Can this be extended to conditions where EXDEV is returned? -- Mike Garrison

This gives EXDEV for clone operations that btrfs could otherwise execute and with slight change of circumstances will actually execute fine. Imagine we have a btrfs on /dev/mapper/foobar with subvols /foo and /bar. Let’s also imagine top of said fs in mounted at /mnt. In this case, a cross-subvol clone of /mnt/...

Hello, This is the second attempt to bring in cross subvolume reflinks into btrfs. The first attempt was NAKed due to missing vfs mount checks and a clear description of what btrfs subvolumes are and probably also why cross subvolume reflinks are ok in the case of btrfs. This version of the patch comes from David and is in SUSE kernels since a long time, so it is tested and working. The patch

The error, which is the status, *if* errno.h has any relation, says that it's an EXDEV, which suggests that it's trying to hard link across devices, which AFAIK it's not: the home directory for the user the device runs is is automounted, and it gets created there. Anyone have any clues why, all of a sudden, the first few packets are showing a status code? Could it be a timin...

Hi, The following series of patches implements in btrfs an ioctl to do out-of-band deduplication of file extents. To be clear, this means that the file system is mounted and running, but the dedupe is not done during file writes, but after the fact when some userspace software initiates a dedupe. The primary patch is loosely based off of one sent by Josef Bacik back in January, 2011.

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. Thanks in advance. -- To unsubscribe from this list: send the line

When using --backup, the sequence (as monitored by strace) is: rename("/path/to/<file>", "<backup-dir>/<file><backup-suffix>") rename("/path/to/.<file>.xxxxxx", "/path/to/<file>") This, of course, leaves a momentary window wherein <file> can't be found. Might it be possible to replace the first rename()
