Solaris 8 has logging mountoption, no need for DiskSuite. As I understand it it logs only metadata changes using same filesystem not other disk, the overhead for space is ca 1MB for 1GB of data. Logging will slow down writes considerably, as I'm told. It's only use is for large critical filesystems, where you can't afford several hours of fsck or filesystem corruption. -- Vallo Kallaste vallo@matti.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
