The ZFS filesystem is always consistent on disk. By taking a snapshot, you simply make a consistent copy of the filesystem available. Flushing buffers would be a way of making sure all the writes have made it to storage. That's a different statement than consistency. > Just curious,is there any manual way of telling ZFS to flush the > buffers after queiscing the db other than taking a ZFS snapshot?. The usual methods of doing this on a filesystem are to run sync, or call fsync(), but that's not anything specific to ZFS. If you're not taking a snapshot, why would you want ZFS to flush the buffers? -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
