Over the last couple of hours I was able to set up a cluster consisting of a management process and data node running in one jail, and a MySQL server and another data node running in a different jail. Once everything was up and running, the cluster seemed to be working excellent, data was synchronizing flawlessly throughout the cluster. Nuking either of the data node processes did not affect access to the data in the cluster, so failover seemed to be working as well. The only problem that I ran into, and it may be user error on my part, is that when the cluster is shut down (or all data node processes are killed), the data contained in the node is lost when the cluster is brought back online. Perhaps there is some recovery step that is required before the cluster can be used again. If someone else has already tested MySQL's clustering ability with FreeBSD, then please let us know the results so that I don't recreate the wheel here. If not, I'll continue seeing how far I can get with it, as I would definitely like to implement this functionality on several of the more critical databases that I manage. -- Justin Hopper <[EMAIL PROTECTED]> UNIX Systems Engineer BSDHosting.net Hosting Division of Digital Oasys Inc. http://www.bsdhosting.net ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

This is a reasonable answer for a home based network or a less critical network. Ethernet tap would be what I would recommend for an enterprise environment. A dumb hub can be pretty decent if you're a small business employee with a T1 connection. If you were to do bridging, should and would you risk having to come in middle of the night because of a hardware failure on the bridge machine? For the time being, I am currently using an IDS machine hooked up to the hub while the t1 router is hooked up to the hub along with the main switch hooked up to the hub. For our colocation facility, I've ordered an ethernet tap and might cancel it because I just realized that the current switch is a cisco and there's high possiblity that it will support SPAN (port mirroring?).

Do you want to keep the whole name lookup in userland or query a cache like ARP is doing and fallback to the userland daemon if no entry exists in the cache? In the later case, you could just reinsert the package into the global queue after adding the cache entry. The cache handling itself could be done via normal routing messages or other communication means like polling a special device.

gmirror bugs, how many?
Hi, I am blindly testing gmirror, just for fun. I got an old 8G drive and did some tests. Maybe I did find a bug in gmirror. This is a long message, but please read it to the end if you are a gmirror or GEOM hacker. First, I partioned (fdisk) for a full FreeBSD system, with sysinstall, which got me this: *** Working on device /dev/ad1 *** parameters extracted from in-core disklabel are: cylinders=16368 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=16368 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 16498881 (8056 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 1023/ head 15/ sector 63 The data for partition 2 is: The data for partition 3 is: The data for partition 4 is: Then I tried to compose a single disk gmirror with the whole ad1 disk: sigesc::root jcmendes [531] gmirror list sigesc::root jcmendes [532] gmirror label -b load -v vol0 ad1 Metadata value stored on ad1.

Re: HD Mirroring
Ok Brian; I read about NDBClusters but the info I found said it would only run on linux and solaris. No FreeBSD. I didn´t know of mysql replication ! I´ll check into it too, but what i´ve been reading about vinum so far has impressed me a lot, specially in terms of not only mirroring the database but most anything you want. Maybe I´ll try to replicate the database on vinum volumes to get the best service performance from mysql, with the "failsafetyness" of vinum mirrors.

restore hangs system creating directories.
Consistently, I can hang my system with restore. The archive is an uncompressed 75 gig file. I run restore -rvf in a new empty directory and restore's first chore is to create the directory tree. restore hangs the machine. It hangs the machine when there's othere read/write going on or by itself. The machine is an athlon-750 with ata-66 disk interfaces and 384 meg of RAM. The disk in question is a 250 gig disk formated with -b 65536 and -f 8192 Now... I can get this to work if I run while true; do sync; sleep 1; done in another shell.

Has it been or can it be done at all? Actually, it has been done, and it has been working for quite some time, in several different versions even :) Take a look at the FreeBSD Handbook: http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/ Look at chapter 16, "Storage", and especially 16.5, "RAID". After that, look at chapter 17, "The Vinum Volume Manager". Those will probably contain most of the information that you need :) There is also an excellent separate article about Vinum at http://www.FreeBSD.org/doc/en_US.ISO8859-1/articles/vinum/ Hope that helps!

HD Mirroring
Hi; Don´t know if this is the proper list to ask. If not, please forgive me. Does anybody has any hints on where to go for info about HD real time mirroring in FreeBSD? I have a mysql server that I need to mirror its data on a 2nd HD, either on the same machine or on a remote one, but it has to be in real time. Has it been or can it be done at all? Thanks before-hand for any info, -- //| //|| // | // || -//--//---|| ARIO LOBO // //|| - [EMAIL PROTECTED] http://www.ipad.com.br ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

For instance: hint.sio.0.flags="0x30" forces sio0 to become the system console regardless of the presence of a display adapter. You may also have to tell the boot code and loader to use the serial console; see their respective manual pages. im using hint.sio.0.flags="0x20", and still, only after i removed the vga from the config file did i get the console output on the serial line. i'm using boot0sio, so the boot is also talking via the serial, but the BTX is still using the vga, compiling it to use the serial gave errors. BTX_SERIAL will not work with boot2 (hard drive boot blocks) due to space constraints. It does work for /boot/loader and pxeboot however. Note that it only outputs meaningful text if it crashes anyway, so I wouldn't worry about it. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Martin, nd6_output() in netinet6/nd6.c should be helpful if you want to look. RFC requires routers to queue packets up during layer 2 resolution process (which is why in IPv6 when destination host is down you see !A with huge latency -- i.e. 3400ms due to queueing by the router[1]). If you are queueing however, make sure you use locking or check for any safety mechanisms as you may corrupt mbuf's that are flooding inbound. BTW Martin,, what is the purpose of this intent? Just curiousity of mine. [1]: Some hardware/ASIC based routers violate the RFC unfortunately. It's a little harder to implement there (see J vendor) -J -- James JunTowardEX Technologies, Inc.

This is probably the only solution I can think of right now, but I think poking a queue at regular, short intervals seems to me quite expensive, isn't it? Or perhaps there could be a netgraph node that handles the queue and connects to the userland daemon... but this could make things much more complicated... ? > > Joerg > ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

There's no need to recompile anything; the third-stage loader will automatically use the serial console if the second-stage loader does (i.e. /boot.config contains -h). The reason why there are two versions of the first-stage loader is that space constraints preclude supporting both VGA and serial in the same code. The second- and third-stage loaders have no such constraints.
