Hi,While diagnosing a MySQL crash (on a Centos 5.7 box), I noticed that it had failed with ENOSPC earlier; it was rebooted after that; now after reboot, even though space was there, ENOSPC was showing up, I also did df -i and it showed inodes available. At this point, mounting with inode64 option was tried, which fixed it. http://oss.sgi.com/archives/xfs/2011-03/msg00299.html helped me here.
So, I have attached a patch here. ===================================================================== When a ENOSPC is encountered and it is due to lack of inodes (particularly without inode64), it is not possible to detect this (df -i doesn't help here), so adding a printk which can aid in detecting this.
