This is a 4.11-STABLE from Dec 24. After a sudden power loss, one of the disks (ad2) can not recover. It was "dangerously dedicated" and had two partitions -- swap (ad2b) and data (ad2e). Any attempts to use either (swapon, fsck, mount) now result in EINVAL. `disklabel ad2' creates an imaginary label with only the ad2c covering the entire drive. If I try to add the ad2b and ad2e in disklabel (I remember the sizes), I get: disklabel: Operation not supported by device I can read from /dev/ad2 directly. How can I restore access to the filesystem?

Any plans, rumours? Nullfs works better than unionfs. Unionfs worked well in 4.X. Despite numerous minor bugs such as being unable to cope with FIFOs, several people have reported using it quite successfully on production systems. However, unionfs no longer works quite as well in 5.X or -CURRENT. There are several reasons for this: 1. Nobody seems to have both the time and interest to maintain it. 2. Developers can't be expected to prevent regressions in something that's unsupported. 3. There are a couple of people who always respond to questions about unionfs with comments along the lines of: ``It's broken, so we won't help you. Go away and don't tell us if you find any bugs.'' There's some pretty low-hanging fruit in terms of nits to fix.

But the mere existence of even a basic regression test would be a start and would encourage people to not hose things further.

That's okay, my experiences are that nullfs is too fragile and easily exploded ... unionfs itself, though, isn't *rock solid*, but considering the loads that I throw at it on a daily basis, its alot more solid then the man pages indicate ... One server I have running 80+ jails on, each with their own unionfs running on it, and the last crash was a result of: panic: ufs_direnter : compact2 uptimes on our servers, all of which use unionfs extensively: pluto# ruptime jupiter up 11+23:09, 0 users, load 0.65, 0.78, 1.06 mars up 12+01:06, 0 users, load 0.53, 0.50, 0.55 neptune up 1+21:42, 3 users, load 2.03, 3.16, 3.10 pluto up 12+00:54, 3 users, load 1.33, 1.12, 1.34 venus up 12+00:00, 0 users, load 2.99, 10.73, 15.76 venus/neptune each run >80 jails ... And the reason why the other 4 servers are only around 12 days right now is because we just moved the servers to a new rack ... All servers run 4-STABLE, some a bit older, but a couple are less then a month old ... ---- Marc G.

We've ironed out most of of the big bugs (there are still other smaller ones to go, but we are making reasonable progress). A recent version has been included in Knoppix 3.8. > Problem or not it could be easily solved with simple heuristics. > Building a filespace > with unioning shouldnt really be that hard. That isn't quite true. In theory, all you have to do is repeat some operations over many branches. In practice, building a Unioning file system is not an easy task. There are very many corner cases to deal with, and what were previously atomic VFS ops can require many operations.

(At least last time I tried with 1.0.3) You should NEVER be allowed to unmount an underlying file system of a stackable file system, if it's busy or in use, no more than you can remove a /dev/sda drive while ffs is mounted on it. Our approach in the Linux unionfs is to prevent users from shooting themselves too much in the foot. :-) However, our unionfs does provide mechanisms such that read-only or non-busy file system branches in the union, *can* indeed be removed safely. Generally we can support arbitrary insertions and removals of branches anywhere in the (fan-out) union; however, we found out that most of our unionfs users rarely want or need that. BTW, the latest version of our linux unionfs is 1.0.9.

I fully agree that a regression suite is needed. Since my group develops a lot of file systems, we have been doing two new things in the past year: 1. We've extracted a subset of the VSX-PCTS posix test suite that just deals with file systems related system calls, and made some changes to it to make it easier to test an arbitrary file system (the package had all sorts of hard-coded assumptions). We've been running it for more than 2 months now and caught dozens of bugs in our file systems, which we're fixing nowadays. Note: in the past, we've used postmark, fsx, bonnie, large compiles, and more as ways of testing file systems' stability; but the posix test suite was able to catch lots of corner cases more directly that none of these other packages could. I fully intend to make this re-packaged VSX-PCTS tool available publicly. And I wholeheartedly recommend it to anyone who develops or maintains file systems. 2. Unionfs has different semantics than regular file systems. As Charles said in his email, unionfs *seems* easy conceptually (we thought so too), but the devil is in the details. It's much harder in practice to deal with all of the unusual border cases and semantic ambiguities that unioning introduces. So, we've begun building a unionfs-specific regression test suite, which we continue to enhance and release together with our unionfs sources. Examples of tests we try is mixes of readonly and write branches, forcing conditions that will result in copy-ups and whiteouts, etc. Although our test suite is specific to our linux implementation, conceptually both the bsd and linux unionfs's are the same, and so the test suite we have could be easily adapted to suite freebsd's needs. Anyone can download our unionfs software and the testsuite within from here: http://www.filesystems.org/project-unionfs.html You may consider it the first ever response to phk's request. :-) Cheers, Erez.

I saw that a few years back a few people were working on getting GFS working on FreeBSD, but there's no recent mention of that. Is anyone working on this, or would someone like to work on it? I am not much of a code guru, but I have the resources to test this technology under all types of loads, and we are currently using a commercial software to handle my needs (polyserve - which they have flat out told me 'no' for FreeBSD support), but I would much prefer to be on FreeBSD.

ENBD [2] isn't based on the same concept, it "exports" block devices through network via userland application, though it needs a kernel module for client side. I'd like something like DRBD exists for FreeBSD but I'm not aware of such an implementation.

You want geom_gate. See the ggatec, ggated, and ggatel manpages. Note that none of the packages mentioned so far will give you a cluster filesystem; they are just a cheaper way of sharing block devices than a Fibre Channel SAN. -- Dan Nelson dnelson@allantgroup.com From owner-freebsd-fs@FreeBSD.ORG Fri Mar 11 15:41:10 2005 Return-Path: Delivered-To: freebsd-fs@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 8D51916A4CE; Fri, 11 Mar 2005 15:41:10 +0000 (GMT) Received: from mh1.centtech.com (moat3.centtech.com [207.200.51.50]) by mx1.FreeBSD.org (Postfix) with ESMTP id EEC1F43D1D; Fri, 11 Mar 2005 15:41:09 +0000 (GMT) (envelope-from anderson@centtech.com) Received: from [10.177.171.220] (neutrino.centtech.com [10.177.171.220]) by mh1.centtech.com (8.13.1/8.13.1) with ESMTP id j2BFf93h052589; Fri, 11 Mar 2005 09:41:09 -0600 (CST) (envelope-from anderson@centtech.com) Message-ID: <4231BC11.7030604@centtech.com> Date: Fri, 11 Mar 2005 09:41:05 -0600 From: Eric Anderson User-Agent: Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.7.5) Gecko/20050210 X-Accept-Language: en-us, en MIME-Version: 1.0 To: Florent Thoumie References: <4231B19D.8060406@centtech.com> <4231B7D5.3070306@xbsd.org> In-Reply-To: <4231B7D5.3070306@xbsd.org> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit X-Virus-Scanned: ClamAV 0.82/761/Thu Mar 10 15:01:48 2005 on mh1.centtech.com X-Virus-Status: Clean cc: freebsd-fs@freebsd.org cc: Adam Maloney cc: freebsd-hackers@freebsd.org Subject: Re: Global / Cluster / Shared filesystem for FreeBSD?

And all in user level. It is also share some same ideas as GoogleFS (http://unix- driver.org/books/linux/filesystem/googlefs/p125-ghemawat.pdf). And for Sistina's GFS (which sold to Redhat now), its 2.0 version has an un-finished FreeBSD porting, which can be downloaded from its ftp server (the address is not on my hand now, and I can tell you if you really want it). Last year I have worked on porting that GFS to Darwin (since it use FreeBSD fs codebase), so I'll glad to talk to you about it ;) Sorry for confusing ! The mail is wrote very late here.

If you've got money to throw at the problem, you might talk to Isilon and Panasas. Both build clustered storge solutions (you buy their hardware) that happen to be based on FreeBSD.

Simplified it looks like this: blkoff = -1; bp = NULL; for (...) { offset = non-negative value; if ((offset & ~bmask) != blkoff) bp = non-NULL; [dereference bp] } So it is guaranteed that `((offset & ~bmask) != blkoff)' will be true the first time around the loop and hence bp will be non-NULL. Does that seem ok?

Not knowing how the tool works my guess is that the function pointer um_blkatoff used in UFS_BLKATOFF makes it impossible for the tool to prove that bp will always be non-zero at this point. Can you replace UFS_BLKATOFF(vp, (off_t)blkoff, NULL, &bp) with ffs_blkatoff(vp, (off_t)blkoff, NULL, &bp) and rerun the test?

I'm all for helping out a project like that, but in this case, I really need a result I can use in FreeBSD, not linux.

If they do, please let us know. I'd definitely toss in the equivalent of a couple of steak dinners (personally, not "corporately"). As the recent discussions on the SAGE mailing list (and elsewhere) have brought up, we're going to need either AFS or NFSv4 (client *and* server) or an equivalent in the near future to be able to meet newer and more stringent security policies. As a Unix and security consultant, solutions that address that on FreeBSD are a topic of interest to me :-) > I think if I knew it was going to FreeBSD work, I could swing that.

I couldn't find it in my meager googling. Do you have any insight as to when a 'real' FreeBSD port of GFS will be around? Sorry, seems I gave confuse. The code is old (which is GFS 3.0), and just can't work fully. It was in ftp.sistina.com/pub/GFS, and if you just open ftp.sistina.com, nothing will show-up (it hide its `pub' from public ;) ). 3.0 has a un- finished FreeBSD code described as following mail. 2.0 has GFS SGI code. http://docs.freebsd.org/cgi/getmsg.cgi?fetch=95974+0 +archive/2001/freebsd-fs/20010225.freebsd-fs serves its status.

Notably, it will not "correct" improper reference counts. So, it would be OK to decide that it wanted to remove the directory, and to do so, provided that it consumed only two of the three reference counts on the directory inode. That is it could remove the name and contents of the directory, but it would have to leave the inode allocated (and unnamed) with a reference count of one. When the background fsck eventually came across it, it would decrement its reference count by one which would then cause it to be freed. Kirk McKusick
