Correct some issues with zfs boot. - Teach it to read gang blocks. (essentially untested) If you see "ZFS: gang block detected!", please let me know, so we can either remove the printf if it works, or fix it if it doesn't. - If multiple partitions exist on a disk, probe them all. We also need to reset dsk->start to 0 to read the right sector here. - With GPT, we can have 128 partitions. - If the bootfs property has ever been set on a pool it seems that it never goes away. zpool won't allow you to add to the pool with the bootfs property set. However, if you clear the property back to default we end up getting 0 for the object number and read a bogus block pointer and fail to boot. - Fix some error printfs. The printf in the loader is only capable of c,s and u formats. - Teach printf how to display %llu

This patch addresses an overflow in the the zfs boot code and allows users to boot from zfs raidz volumes. This has been tested by a number of users and does not impact those which are not booting from zfs raidz volumes. Submitted by: Matt Reimer

below) as well as the following: - the recurring deadlock was fixed by deferring vinactive to a dedicated thread - zfs boot for all pool types now works Submitted by: dfr - kmem now goes up to 512GB so arc is now limited by physmem - the arc now experiences backpressure from the vm (which can be too much - but this allows ZFS to work without any tunables on amd64) - frequently recurring LOR in the ARC fixed - zfs send coredump fix - fixes for various PRs Supported by: Barrett Lyon, BitGravity Revision 185029 - (view) (annotate) - [select for diffs] Modified Mon Nov 17 20:49:29 2008 UTC (6 months ago) by pjd File length: 38244 byte(s) Diff to previous 177698 Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes. This bring huge amount of changes, I'll enumerate only user-visible changes: - Delegated Administration Allows regular users to perform ZFS operations, like file system creation, snapshot creation, etc. - L2ARC Level 2 cache for ZFS - allows to use additional disks for cache. Huge performance improvements mostly for random read of mostly static content. - slog Allow to use additional disks for ZFS Intent Log to speed up operations like fsync(2). - vfs.zfs.super_owner Allows regular users to perform privileged operations on files stored on ZFS file systems owned by him. Very careful with this one. - chflags(2) Not all the flags are supported. This still needs work. - ZFSBoot Support to boot off of ZFS pool. Not finished, AFAIK. Submitted by: dfr - Snapshot properties - New failure modes Before if write requested failed, system paniced. Now one can select from one of three failure modes: Before if write requested failed, system paniced. Now one can select from one of three failure modes: - panic - panic on write error - wait - wait for disk to reappear - continue - serve read requests if possible, block write requests - Refquota, refreservation properties Just quota and reservation properties, but don't count space consumed by children file systems, clones and snapshots. - Sparse volumes ZVOLs that don't reserve space in the pool. - External attributes Compatible with extattr(2). - NFSv4-ACLs Not sure about the status, might not be complete yet. Submitted by: trasz - Creation-time properties - Regression tests for zpool(8) command. Obtained from: OpenSolaris
