As a non-developer on this mailing list I would like to add that I would love to see this feature too. This is feature that is available on some other OS'es out there and is being used in combination with enterprise SANs for backup & disaster recovery purposes. I think what we're talking about here is a feature that appears to be present in XFS: http://man-wiki.net/index.php/8:xfs_freeze Speaking as an end-user here, I would love to see this type of feature implemented and made available for all Linux filesystems. A long while ago I asked about a possible implementation of a freeze/thaw feature for ext3, but I don't think ext3 has this feature. I believe it's possible to work around this by using LVM, but when your storage is en enterprise-class highly available SAN with snapshotting built in, you don't always want to implement LVM in order to get snapshots of your Linux filesystems.. Is there a reason why this needs to be implemented in each filesystem individually rather than at a more generic layer ?
