apropos the recent discussion on superblocks and whether they ever get corrupted, I just got a call from a friend. One of his cluster nodes had power-failed at a bad time, and fsck was indicating a superblock corruption problem. I told him about -b 32, which he had never had to use in four years of running a large cluster. This problem was so new to him that he in fact had never heard of the -b switch or the backup superblocks. He couldn't affort to lose what he had on this node, as he was in the middle of changing something and had not had a chance to back it up to a server. Backup superblocks are still a good idea, even when you only need them every few years. ron To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
