Softupdates guarantees that you won't get corruption due to metadata pointing to invalid or stale data blocks. That's not the same as guaranteeing that there won't be any corruption. Write caching on the drive combined with an in-opportune power loss or other failure can easily leave you with corrupt or incomplete metadata and/or data blocks. A panic while metadata is being committed to disk can also leave the metadata highly inconsistent and prone to corruption. This isn't to say the SU is bad or that other strategies are necessarily better, just that there are definite risks. ScottReceived on Mon Jul 26 2004 - 15:43:14 UTC
