Thanks for the information. As an aside, I had it happen on a workstation that I was using to watch a movie over NFS. Strangely the BTRFS hang caused video playback to pause. I didn't expect a BTRFS issue like that to stop access to an NFS mount from another system. Would it be locking up inside the VFS? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
