At any rate, it is a fixable problem. FreeBSD has been able to run swap over NFS for as long as I can remember, what is different in Linux that makes it especially difficult? I've read that swap over non-trivial filesystems is hazardous as it may lead to a situation in which memory allocation can fail in the swap/FS code that was meant to make allocation possible again. If btrfs is to take the role of a RAID and volume manager, it would certainly be very useful to be able to run swap on it, since that frees up other volumes from an administrative standpoint. -- Dmitri Nikulin Centre for Synchrotron Science Monash University Victoria 3800, Australia -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
