Hi all, I want to combine two data sets (ZA and ZB to get ZAB). The common variable between the two data sets is ID.

Hi. petrb@bots-bnr1:/mnt$ btrfs subvolume delete ext2_saved/ Delete subvolume ''/mnt/ext2_saved'' ERROR: cannot delete ''/mnt/ext2_saved'' this is not really very descriptive. It would be really cool if it told me why it can''t delete it. For example: Permission denied. Cannot delete ... Disk write error. Cannot delete Descriptive error messages

Hi gang, I was a little surprised to see that patch go by recently which fixed an endian bug. I went to see how sparse checking looked and it was.. broken. I got it going again in my Fedora environment. Most of the patches are just cleanups, but there *were* three real bugs lurking in all that sparse warning spam. So I maintain that it''s worth our time to keep it going and fix

Hi gang, Here''s some trivial cleanups that I''ve built up while reading through the code. They''ve been run through xfstests -g quick. - z -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

...itations We can''t yet dedupe within the same file (that is, source and destination are the same inode). This is due to a limitation in btrfs_clone(). Code review is very much appreciated. Thanks, --Mark ChangeLog All of this rounds fixes are thanks to review from Zach Brown <zab@redhat.com> - test for errors from extent_read_full_page_nolock() - use kmap_atomic() instead of kmap() - WARN_ON and return an error if blocksize < pagesize - describe the use and reasoning of BTRFS_MAX_DEDUPE_LEN in comments - explicitely check !S_ISREG on input files now - copy argum...

Hi! Is there a way to view ext3 filesystem's maintained journal (in a human-readable-format)? I ask, because i have had a server crash before and now i'm wondering if i might take a look at last things that my server did straight before crash. I guess clarifying log insertions might be lost before buffers were flushed to disk. Thx.

Hi list! I recently butchered my filesystem, and I was wondering if anyone knows how to help. Problem: My filesystem is screwed up, and I can''t mount it at all right now. In the logs, the problem begins around 45s. Background: I''m running a 6x4TB RAID5 array using md. I have a few virtual machines using said array, and one of them is a btrfs storage server. I ran into some

When the binary search returns 0 (exact match), the target key will necessarily be at slot 0 of all nodes below the current one, so in this case the binary search is not needed because it will always return 0, and we waste time doing it, holding node locks for longer than necessary, etc. Below follow histograms with the times spent on the current approach of doing a binary search when the
