Title:
xfs_growfs fails to allocate new inodes in Ubuntu Trusty
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Trusty:

Bug description:
Release:
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Packages:
linux-image-3.13.0-46-generic 3.13.0-46.79
xfsprogs 3.1.9ubuntu2
When using xfs_growfs to grow an xfs filesystem, inodes on the grown
portion of the filesystem are not available for writing, leading to
ENOSPC errors even when free disk space and unused inodes are reported
by df -i and df.
Actual results:
A worker creating many files, will run out of inode space as if the fs was
not grown.
Expected results:
A worker creating many files, will continue to create new files for the grown
fs.
mount -o remount,inode64 /mnt/point fixes this issue and allows
further writes to the grown fs.

Also, the LXC FAQ has a description that indicates this bug has been
present since kernel 3.7. It also offers the work around I wrote
above:

This bug has been fixed upstream in 3.17:
