I'm writing because we need volunteers to help run the table. The conference will be right in the center of downtown at Market and 3rd. Talking to folks at tech conferences is a great way to help spread the word about free software and a great way to help us increase our membership base. And as it turns out, it's also fun! I've split the days in half, so let me know which half of which day you can help out. Thanks again for supporting free software! Here are the times: Tuesday, August 7th 10:00am-1:30pm 1:30pm-5:00pm Wednesday, August 8th 10:00am-1:30pm 1:30pm-5:00pm Thursday, August 9th 10:00am-1:00pm 1:00pm-4:00pm Let me know if you have any questions. See you in San Francisco! Thanks!

I might not schlep *all* of them to today's BUUG meeting, but in addition to the book I mentioned earlier, I'll bring at least two of these additional books to today's BUUG meeting, and any remainder hopefully to the 2007-09-06 BUUG meeting. I've also got some fresh LINUX and other magazines from LinuxWorld for BUUG* - I'll bring at least some of those to today's BUUG* meeting, and any remainder hopefully to the 2007-09-06 BUUG* meeting. Anyway, here's the list of additional books that arrived: ISBN-13 ISBN-10 Title 9780132338691 0-13-233869-6 The Official Damn Small Linux Book 9780132242066 0-13-224206-0 Enterprise AJAX 9780321480798 0-321-48079-1 RailSpace 9780132354134 0-13-235413-6 The Official ubuntu Book 9780132350082 0-13-235008-4 Ajax Construction Kit I've also got some SUSE Linux Enterprise Desktop 10 DVDs (based on packaging I'd guess that they were at least originally published to go with LINUX Magazine Isssue 82 Sep 2007). I'll bring at least some of those to today's BUUG* meeting too (and perhaps also some to the 2007-09-06 BUUG* meeting). *of the LINUX and other magazines (and DVDs, CDs, etc.) I picked up at LinuxWorld, I'll bring some to BUUG, and some to BALUG (http://www.balug.org/). BALUG will also be seeing some more books in its future: http://lists.balug.org/pipermail/balug-admin-balug.org/2007-August/000401.html (BALUG isn't on any program where it regularly receives book shipments from publishers, so most of the books from the URL above will go to BALUG. BUUG is part of Pearson Education User Group program, an thus BUUG typically gets a shipment roughly about monthly of typically 2 or 3 books - 5(!) books in the most recent shipment to have arrived).

Knowing the LVM version (of the LVM packages and such, and perhaps of the LVM volume groups also) might also be quite informative ... and perhaps also the operating system version (I was almost going to say could be most any ... including even HP-UX ... but /dev/jj-internal/usr tends to make me think it's probably not HP-UX). Of course with LVM being open source, dear knows what it may be ported to and running under (though it would mostly behave about the same anyway). Anyway, how about these items for starters: Have you confirmed that nothing (most notably PIDs) is still using any of the LVMs - e.g. nothing using those LVM filesystems (if still mounted) or LVM devices (such as a database using a raw LVM device file)? If those LVM files are in use, one will likely need to terminate those PIDs, or at least have those PIDs no longer using those files or filesystems. If the PIDs get to be hung and unkillible due to I/O errors (from the devices being gone) it may turn out that not everything can be freed up (without either a reboot, or at least providing the device back again - or possibly some other device that would at least allow hung reads/writes to proceed ... even if the data would be inconsistent). Have you lvremove(8)d the LVs? Did you try the --force option? Have you vgreduce(8)d the VG to zero size (if that's the only device in the VG) or completely removed the device from the VG via vgreduce(8) if the VG also spans other device(s)? Were you then able to vgchange(8) -a n the VG (if nothing else was in it)? Were you then able to vgremove(8) the VG (if it uses/used no other devices)? If not, at what point did things fail? What error diagnostics? What return code (exit value)? Does your man page for the command that was attempted and failed tell us the particular significance of that return code? I don't think vgscan(8) - at least in in general - removes LVM stuff. It's mostly used to pick up and add LVM devices that aren't already known to LVM. I could probably create a similar scenario and "solve" it, but it may not be applicable, or applicable in quite the same way as in your case. After all, we're trying to find solution to your problem, not to the problem I haven't created yet :-).

In any case, behavior does vary someone depending upon *NIX flavor or LINUX distribution. Red Hat / CentOS / Fedora are particularly stubborn about wanting to check the filesystems if that last field isn't 0, and if any of the checks fail (e.g. device isn't available, or filesystem type isn't available at that point in the boot sequence), not only does it fail and want a check, but it pretty much coerces one into rebooting - can't just repair it or comment it out and proceed (at least not at all easily). Many other LINUX distributions are a bit more "user"(/administrator) friendly in that realm, ... at least allowing one options other than a forced reboot. Behavior in the UNIX realm (and likely also BSD, etc.) tends to vary even more.
