'too much hardlinks' error
Last modified: 2014-05-14 12:04:44 EDT
Description of problem:
The btrfs filesystems created by mkfs.btrfs are hitting EMLINK errors with low counts of links:
$ cd <btrfs-directory>
$ echo x > <M-250>x # M-250 means, pressing meta key + entering 250
$ for i in `seq 0 14`; do ln -f *x <M-250>x$i; done
ln: failed to create hard link to 'xx...': Too many links
I am aware that btrfs had a very low hard link limit but afaik it was removed in kernel 3.7 by introducing extended inode refs.
I tried 'btrfstune -r' and 'btrfstune -x' on the filesystem but problem still remains.
Version-Release number of selected component (if applicable):
This is a mass update of F19 and F20 btrfs-progs bugs.
A btrfs-progs git snapshot has been built in Rawhide and submitted for F19 and F20 testing.
If your bug was reproducible, please re-test with the new build, and update this bug to let us know if it's been resolved. If so I can add it to the Bodhi errata.
btrfs-progs-3.14.1 has been pushed to Fedora 19 and 20 for testing.
I frankly have no idea if this will resolve your bug or not, but if you test it and find that it does, please take the opportunity to close this bug. :)
This all works upstream, as far as I know. If not, feel free to re-open with current version details.
