I was looking at the open-afs project to create a network data storage cloud. As machines are retired they would be added to the data storage cloud and all data would be split across several machines like raid5. Is this or can this easily be implemented using open-afs? Short answer to a 'long' question ;-) no. AFS is a 'file system'. This means it _uses_ disks and it doesn't provide some. You can build your 'data cloud' by an AFS cell, but that's one layer above that (what I think you had in mind). AFS can provide a complete distributed filesystem, where clients and users aren't aware of the whole organization of data and servers behind. It comes with a complete set of management tools for the file system, authentication (if you want some, but that's a little too old for some people) authorization and some backup functionality and some nice supplemental file system goodies. It's not a networked RAID substitute nor a high availability data cluster, etc. (I seem to run out of examples of misinterpretations of a 'distributed filesystem' :-) ) I didn't want to scare you off, and I sincerely hope I haven't, I just tried to clarify things.

The large file support has to be in your client as well as your fileserver, if you want to handle large files. ;-) You should be able to mix clients and servers for files 2GB. I also have one 1.4.0 -server. What happens if I put the large file on 1.4.0 and try to access it from 1.3.81 clients? What if I replicate the volume to 1.3.81 fileservers? Shuold I force all fileservers to be of the same version? I don't remember if 1.4.x has large file support enabled by default, since I don't use packages, but if it doesn't, you only get into trouble when you mix in the 'wrong direction'. Which means, you better don't handle large files with a server or client which doesn't have it supported. (kinda obvious, isn't it?) For the replication part, you actually shouldn't be able to release volumes with large files on a server which doesn't support that. On my machines the 'vos release' fails, but I'm not sure there aren't any cases where it appears to be working.

The problem was, that you could cause timeouts on file transfers, if you do a few 'vos examine' calls, due to the disk operations those calls would trigger. I think it's trouble to go back. BTW, 'vos release' won't do any transfer if the RW volumes didn't change. Horst ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info

Therefore, there is now an irreconcilable conflict that will cause the vos command to write a message to the standard error stream. The vos command never removes volumes from file server machines.

The hotswap may then work as follows: all /vicep* and /usr/afs (tranarc paths assumed) are on an external storage. If/When fileserver A breaks, you shut it down. A standby node B, with the same OS than fileserver A (which is up to this place _no_ fileserver) mounts the stuff on the external storage. Then you startup the fileserver binary on that. I did something like this years ago and it worked, but somehow I still have a bad feeling about doing it ;-) It was using FibreChannel devices, which are very easy to 'move'.

Excellent, that makes things so much easier For the rest of the questions, I don't know how you think you can 'network' RAIDs. I was referring to using something like ENBD to create a RAID array across a network That's on what I commented further below.

Indeed, what i was referring to is having 4 servers and maintaining some form of redundancy, so that the AFS volume (namespace?) could survive a single server failure, whilst having more than the 180 gig currently free on each machine. I kinda assumed it was impossible So, you expect a network interface failure, or machine failure? Since you can have a lot of redundancy with your RAID design. What I meant by 'namespace', is how afs appears on all of your clients. You'll have a (more or less) fix mount point '/afs' for the AFS space. From that point on, everything is 'free'. You can mount volumes from foreign cells, mount volumes multiple times, whatever you want to do. This tree looks the same on all of your clients. The replication of volumes in AFS works only for read-only data. Maybe you read about that, and that's where most people start getting 'design ideas'... ;-) Strictly spoken, you could build that kind of redundancy (something like network based RAID 0) with AFS, but I consider that, abusing the design. If you think of placing the network some layers lower, like in the block device, etc., AFS can't help. Yeah i figured as much, i was just wondering if AFS contained any way of doing the above. Yes and no ... What you plan is doable with AFS, but I'm not sure you'll get an optimal solution by just using AFS.

As a result I'm now interested in getting a broad overall picture of it and have several questions. A recent post stated that they had about 7000 users in a single cell, I'm wondering what a realistic maximum is (assume 'average' end user file activity - nothing extraordinary). I saw in the archives a refernce to 45k and a statement that UMich had 100,000. Are these (especially the 100,000 for UMich) confirmed numbers? If anyone out there has a larger cell or knows of someone who does could you provide specifics? Right now I'm not so concerned with how many file servers I would have to have or other particulars as I am about what a realistic limit is with a proper configuration. The increasing number of users isn't primarily related to the number of the fileservers (these are very easily addable to a cell) but to the database servers. If you have a very heavy 'loaded' cell the calls to the protection service (ptserver) are worse than teh quantity of any other call in the cell. You can design your volume location so well, that it scales almost optimal for file access, but you still have those calls for permissions from the fileservers ending up at a smaller number of protection servers. (... just some thoughts about what you have to consider in the design of such a large cell) If I'm not terribly mistaken there were cells with more than 130,000 users around some years ago, but I don't know how 'active' those users really were. How does AFS compare in administrative burden compared to the common PC NOSes (NetWare and AD)? Is it more intensive, less or about the same for a given type of user population? A related question is how sensitive is it, do you have to be overly careful in order for things to work correctly? If you're looking for a fancy graphical administration tool like a Windows server will provide. I don't know of any. AFS administration is completely scriptable, so after some time in administering your cell, you'll end up with some nifty scripts or small programs doing almost everything of your daily work. Maybe some automatic work done at night as well :-) How stable and trouble free is the Windows client? (I saw a statement that the Windows server was considered experimental and not being maintained). The later statement unfortunately is true, but the client is used by many people and is well maintained. ;-) I never had any major problems with the client, but I'm not using it that heavily. Is there a Linux GUI for day-to-day administration? Not that I know of. After some time you don't need it. Believe me ... ;-) What is the status of server-side byte-range locking? If this isn't a near-term reality what alternatives do people use (SQL server is obviously a possibility, are there other alternatives for MS Access style databases and other byte-range locking needs)? If you want to use that for databases put into AFS. Don't ... And besides, what do you gain from a database where you share the files? Maybe for Access it's useful, but if we're talking about big databases, you shouldn't do that. What are people doing for printing, particularly Windows printing? They use Samba, if you want to print from windows boxes and your servers are UNIX. Or use CUPS, which is also very portable. But that's a completely different story. What about workstation customization (consistent look and feel from workstation to workstation, workstation restrictions, etc.)? What are the alternatives there? That depends completely on the workstation, doesn't it? This is not really related to AFS. AFS just provides a nice way of having the same files on all the workstations in the same place (nice feature the global namespace, isn't it?) I'm not looking for detailed responses just reasonable approximations of OpenAAFS reality, thank you for any replies.

This requires: (1) Restarting the server processes, since you can't add or remove vice partitions from a running server. (2) Doing a vos syncv on the added partition, so that the volumes on that partition get attributed to the new server in the data base. Other than this nuisance, it seems to work well enough.

Wouldn't want to fry other people's rootfs en mass :) Running openafs-latest, I think was 1.3.86 when I started seeing the problems (date was 1st of august). Rootfs is ext3, kernel is linux-2.6.13-gentoo. You ran a fs check? I did after I started loosing my libraries. I've read that you shouldn't run fsck on a /vicepx, but I guess this was only for the namei-fileserver (right?, as opposed to the inode-one where I suppose you can run fsck) and also not for the cache? Is there any up-to-date documentation on this? You shouldn't run fsck on _some_ platforms on an inode fileserver partition. I assume you don't have one of those since it's a lot of pain if possible at all to actually be able to run an inode fileserver on Linux (I don't know anybody doing that on Linux), it's not related to your problem. AFS has nothing to do with your vanished libs. I'm pretty sure of that.

When I type /etc/rc.d/init.d/afs start I get the following error message: Failed to load AFS client, not starting AFS services. This message sounds a lot like your kernel module is not loaded correctly. I actually never looked at the current start scripts since I always have my own. The trivial solution to this is you do a lsmod to check if the kernel module is there. What could be the reason for this? Here are the steps through I went: # ./configure --with-afs-sysname=ppc_linux24 --enable-transarc-paths # make # make dest I copied the entire /motload directory, which appeared after the build in /usr/src/openafs-1.2.8/ppc_linux24/dest/root.client/usr/ vice/etc, AND the asfd file to /usr/vice/etc, and the afs.rc file to /etc/rc.d/init.d/afs # cp -rp /usr/src/openafs-1.2.8/ppc_linux24/dest/root.client/usr/ vice/etc/motload /usr/vice/etc # cp -p /usr/src/openafs-1.2.8/ppc_linux24/dest/root.client/usr/ vice/etc/afs.rc /etc/rc.d/init.d/afs # cp -p /usr/src/openafs-1.2.8/ppc_linux24/dest/root.client/usr/ vice/etc/afsd /usr/vice/etc According to the Manual from openafs.org, that should do to start the AFS client whit the command. # /etc/rc.d/init.d/afs start But it didn't. So can someone give me some ideas what I did wrong (or what I didn't do at all), or maybe how to get more detailed information about the errors ocurring? Here's what I would do first to debug. You locate the kernel module which should be in src/libafs/ MODLOADxxx (it should be called libafssomething). Then after a reboot you load it by hand, calling insmod module file name, now you start the afs daemon by starting src/afsd/afsd and maybe you want to use -debug -verbose parameters, so you'll be able to see what's happening during initialization of afs. That should give you a running client. Of course you need a working network, an afs cell and a proper configuration of your client (CellServDB, ThisCell, cacheconfig and some servers :-) ) Horst ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info

BTW, OpenAFS can only be compiled as a kernel module for Linux (not built static into the kernel) and an appropriate place would be any you like on the root filesystem. Sorry for the confusion again. I'm used to transfer the root fs as well together with the boot image onto the target and boot from flash or whatever there is. Stupid wording mistake... You can, of course, have your root fs somewhere else. (NFS, etc.) For client functionality you need the kernel module, the afsd deamon and a proper configuration (this means all configuration files).

That won't work. You talked about integrity. That's exactly the key word here. What should happen if one of the fileservers comes back with an old version of every file in the volume? What should happen if a client wrote to a fileserver and that one fails? (when we still have a connection to that server and no replication...) How are your replicated volumes reacting to that? Those are just a few very simple scenarios that came to my mind without really thinking much about it. It's a lot _more_ complicated than that and I'm not talking about the changes to the protocol and the servers which aren't compatible any more so that we can't use servers and clients from different versions. for an append-only service writing into volumes the ro-clones are the right model to store the data long-term -- but while the volume is r/w it needs to still be more available than a single fileserver.

(Be aware that there needs to be a special compile-time option enabled to support blockdevices larger 2TB.https://lists.openafs.org/pipermail/openafs-info/2005-April/ 017336.html) Can't comment on that since I never had such devices :-) Maximum cache size: My experience is that you want your client cache to be at least as large as the largest files you are using. Performance on files that won't fit entirely in the cache is terrible. ... Setting cache size is a bit of a black art. https://lists.openafs.org/pipermail/openafs-info/2005-April/ 017552.html Yes, cache size and parameters for the clients is more like a religion :-) Total size of largest known AFS installation: Now here i think you won't get any proud and cocky answer since the AFS guys are not running around with the number of TBs around their neck for every body to know. :-) BTW, if you're using AFS it's the same way of handling data whether you handle 2.1GB or 200TB. Can an AFS volume be grown in size? Shrunk in size? While online? They do that all by themselves since a volume is not a physical unit but an administrative one.

If the master copy of any file in this volume changes, then all replicated copies of this file are deleted, and the next request is forwarded to the master server. Write requests are forwarded to the master server. That way multiple clients at one site can share the one cache copy. Jeffrey I don't understand how this would help share a cache. Jeffrey The cache data would still have to be read over the Jeffrey network. The replicated copy could be installed on a fast LAN when the master server is on a slower WAN. This would help in the situation where a number of clients at one site need to access data from a remote site. If the cell design is made that way, yes. But don't blame that on AFS. AFS chose by design caching is done on the client side. That's about it ... I need to talk to my client more about their requirements - I suspect in this case it would be better if the servers were distributed, not centralized as was requested. Still, I think the above would be a good feature for applications that require distribution of large files across a large number of clients across a small number of sites. Caching on the clients is good, but it requires repeatedly downloading each file on each computer at a site, which could be expensive if it has to be downloaded from a WAN connection. Do I get you right?? You're trying something like the every cache manager is a server in some way thought? Don't think further. That's not what AFS was ever designed for. Examples of large files could include video files, CAD designs, etc. This is simple if files are only changed at one site (use rsync + http mirrors for example), it becomes more complicated if files can change at any site. AFS has support for the first of you ideas. The second one is not that easy to solve. I don't know of anybody ever achieve to have a stable solution for that. I don't think you want that, if you think of what that means to your server to server traffic. You talked before about servers on WANs which means you don't have that much speed there. If you define site as a client they already can ... :-) but I'm sure, you already got that. Jeffrey Keep in mind that the Windows cache is now persistent. Jeffrey You can cache up to 1.3GB on the client. So you only Jeffrey need to download the data once. If you are planning on Jeffrey reading the same data repeatedly across numerous reboots Jeffrey you might not need to precache as much as you think. The argument was we don't want to load the network during peak periods. I suspect not much thought was put into this. What is this here? Am I correct in my understanding of AFS that any file writes require the entire file be copied back to the master server as soon as the program calls close() on that file? I think my client forgot to consider this. The client somehow wanted read/write access, guaranteed access to latest version, file locking when a file is opened (anywhere), and no files to be transferred except at night. That sounds a lot like the disconnected idea to me. Which is thought of for a long time but not ready yet. Unfortunately, some of these conflicting requirements are simply not possible without adding time travel capabilities (grin) to AFS. I think time travel is beyond the budget of my client... Maybe if you're able to be more specific, we can talk more than just ideas and give more than just maybe and definitely not answers. If your customer has that much of a specific plan about requirements of the system. Maybe they need a customized distributed file system. :-) Horst ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info

What I was thinking was a little different, and might be something that I read about in one of the IBM Storage Tank descriptions. I was thinking that the file server would use a callback to the clients to say that the chunk that you want is at this address (of a closeby client cache) with this ID. The chunk could be transferred and the chunk registered with the fileserver when the transfer is done??? Are you sure it wasn't Distributed Stoarge Tank?

E.G.: /afs/cg.cs.tu-bs.de/cd is only once available as a RW and under CD are only other volumes, no more data. But the cd volume got lost and now we are a bit in doubt which volume was mounted under cd at all...

What you end up doing here is not going through your vldb but going through your afs tree and filling a database whith your mount points. You will end up with a list where every volume is mounted in the tree if it is at all. From that on you can interpret that data however you see fit. I think I saw something like that in the scripts from Russ Allbery... maybe he can comment on this. and so on and so on. Made for a easy and quick overview over the cell.

I am seeing that same problem with 1.3.77 on all AIX 4.3.3, AIX 5.1, and AIX 5.2, both 32 and 64 bit kernel. In contrast to previous versions of 1.3, I can at least load the kernel extensions now. Obtaining a token with 1.3.77 'klog' from a kaserver causes a core dump, and trying to use a token obtained with 1.2.10 'klog' results in a system crash. Yes, I understand that 'klog' and 'kaserver' are considered more or less deprecated, and we are in fact planning to change to a Kerberos 5 setup, but this migration will take us quite some time to complete. Also, we will need continued interoperability with legacy IBM Transarc AFS cells for quite some time to come. So it would be great if 'kaserver' support wasn't silently dropped out of OpenAFS already at this point. I don't think that has happened but maybe somebody else can comment on that... So far, I haven't been able to compile ANY version of OpenAFS client to work on AIX 5. The server code might be less problematic as it doesn't involve kernel extensions, but I am also still running 1.2.11 server binaries compiled on AIX 4.3.3 on my AIX 5.2 servers. The stable tree has never had any support for AIX 5, in any way ever. If you try any, please use the CVS version.

That first one should be osi_Alloc, not osi_AllocLargeSpace.
Yes that looks like a bug. A few lines later, osi_Free will be used
to free the area. It also looks like insize is not greater then
AFS_LRALLOCSIZE as osi_AllocLargeSize tests for this and would
panic: osi_Panic(osi_AllocLargeSpace: size=%d\n, size);
Also I think this code could use a comment. It's a bit confusing that
osi_AllocLargeSpace is being used for small allocs, and osi_Alloc is
being
used for large ones.
Looks like osi_AllocLargeSize and osi_FreeLargeSpace will keep a pool
of
4K blocks off of freePacketList. Thus any size 4K get a full 4K. If
there
is really a large packet like aticket with a big MS PAC, then 4K may
not be
big enough, so osi_Alloc is used directly.
I changed that a long time ago just for testing.
You can use any kernel allocation there. If you allocate those 12k+ the
system will crash.

Although there are still problems with disk cache, the copy from afs to local disk is good enough. With disk cache the speed is ~400 kbyte/s (tcp speed is 500 kbyte/s). Memcahe speed is much lower, between 120 and 160 kbyte/s, depending on the fileserver. Is there any reason (bug) for such a big difference? On gigabit network, the copy speed with memcache is never larger than 20 mbyte/s, with disk cache it can go up to 70 mbyte/s. Can you provide more information on your measuring and test environment? I suppose you didn't actually measured AFS performance when you got 70 MB/s with diskcache. That's pretty unlikely.

Well, it is not actually performance. dd if=/dev/zero to afs space transfer reaches something like that. This is of course a peak number. Half of time data is written to a local disk cache with no network activity, so on average, the transfer would be 30-40 MB/s. AFS read speed is between 10-20 MB/s. New memcache parameters give similar write transfer now (~60 MB/s on average). So basically, you are measuring a combination of how fast you can write to your cache, together with how fast the AFS client can flush the data from the cache to the server. Do you have writebehind turned on or off on your AFS client? If writebehind is allowed, then you only measure writing to the cache + part of the flushing to the server (since flushbehind allows the close() system call to return before the entire file has been flushed to the server). If writebehind is turned on (what I just don't assume) then what do you get?? The numbers won't be of any significance at all. With the sync-on-close on you know how fast your client will be on a normal, unspectacular, daily usage. IMHO that's the average speed you'll have to expect from that system afterwards in production.
