Release Notes

A little overdue: the 0.7.0 release

Of course, all fixed issues and improvements to 0.6.9 have been incorporated;

Mandatory non-exhaustive list of news-worthy items:

• changed the fuse subtype to zfs-fuse This affects the contents of mtab, so everybody with scripts depending on that, please update accordingly!
• pool version 23
• consequently, all Sun's bug fixes; see changelog and upstream. This includes work on Sun BUG 6948890 (snapshot deletion can induce pathologically long spa_sync() times) which became something of a FAQ on the list. Note that datasets removals can still take a long time, especially with dedup enabled*
• robust handling of rollback even when using cache (http://zfs-fuse.net/issues/65); this had been a 'high profile' issue reported on the 0.6.9 release with a workaround delivered in the maintenance version. The workaround however carried a performance penalty for the whole of zfs-fuse (basically killing page caching for zfs-fuse). The new solution is still not ideal, but at least only incurs a penalty when and only when a rollback is performed, this time by dropping all the kernel filesystem caches. We'd much rather have remounted the related filesystem(s) but this cannot always be done, and there is no way to find out whether it did work... We value data integrity above performance in this kind of situation.
• improved init scripts Thanks to all packagers/contributors. There is an upstart script too
• bash completion Contributed by Aneurin Price
• mount filesystems with ACLs (patch by Eric Astor, http://zfs-fuse.net/issues/71). Although I'm not to sure whether the ACLs are (properly) handled, at least zfs-fuse will not abort when a file is used that has ACLs set. Eric Astor did some nice wizardry mapping ids here and there, we'd like feedback from other users that have ACLs?
• Made zpool export and destroy succeed a lot more often (there is a timing issue with fuse umounts and ZFS dataset holds; although we now wait a while before deciding that an export (e.g.) fails, there are still conditions in which you could need to try again. Please let us know if you encounter such a situation, we'd like to get to the root cause here
• Prevent crash on 'zfs get all' with bind mounts
• Fixed local send/receive with deduped streams due to bidirectional pipes missing on linux
• Parsing of zfsrc now robust (several issues)
• new --enable-xattr flag for zfs-fuse daemon. Using xattrs significantly slows down zfs-fuse, but if your application depends on it, now you can enable them. Unfortunately, there is no way to enable/disable this per filesystem (yet).

Branches

Note how the maint branch is now reserved for critical updates to this stable version. The "unstable" branch has been promoted as the new testing branch (sorry to keep you waiting, Emmanuel!). The new unstable branch has been merged with Emmanuels latest work on

• buffering
• improved nfs lock support
• posix acls

The old maint branch is still available as maint-0.6.9 now, in case you want to rebuild a 0.6.9 package on the recommended source for 0.6.9. In general, consider this branch 'inactive'. If the need arises, we might backport very interesting patches to this branch.
