[SLUG] LVM Re-mounting Hell
Hi All. Hoping someone can help. First the question, then the background Q: Can anyone help me re-mount LVM disks to a new machine Background Machine 1, Fedora core 4, 3 disks in a LVM. SOmething went horribly wrong and the box wont boot anymore (I suspect one of the disks has failed) So I have built a 2nd machine with the hope of plugging in the disks from Machine one, mounting them and retrieving some of the data (Whatever is there). Machine 2 has a single 13Gb Drive in it, also set up LVM. I plug in one of the drives from the old machine and it comes up as /dev/hdc with a single partition on it (hdc1). If i run a fdisk -l on the box I get the following: Disk /dev/hda: 13.0 GB, 13022324736 bytes 255 heads, 63 sectors/track, 1583 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 13 104391 83 Linux /dev/hda2 14 1583 12611025 8e Linux LVM Disk /dev/hdc: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdc1 * 1 30401 244196001 8e Linux LVM All good. SO, trying to follow the directions I found on the web at http://forums.teamphoenixrising.net/archive/index.php/t-32150.html (three quarters of the way down the page) and I come up no good. I type lvm and get the correct prompt. I type vgs and get [EMAIL PROTECTED] ~]# vgs Couldn't find device with uuid 'eGeBrP-O0XF-K5qr-g76h-XYut-1bBQ-PbzVdK'. Couldn't find all physical volumes for volume group VolGroup01. Couldn't find device with uuid 'eGeBrP-O0XF-K5qr-g76h-XYut-1bBQ-PbzVdK'.

I just plug a microphone in, adjust the mixer, and it works. You have to use the right microphone for the kind of socket it's plugged in to... dynamic mics are fine; electret mics with external power supply are fine. But mics that need phantom power won't work without an external box to give them the power. And the sensitivity of the input circuitry for some sound cards is appalling... they need an external preamp. -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc AT gelato.unsw.edu.au http://www.ertos.nicta.com.au ERTOS within National ICT Australia -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Do you mean you are striping across the disks using LVM i.e. a volume group/logical volume spanning all three disks? If so, I suspect you are hosed. I _think_ LVM requires the entire volume group for you to be able to bring it up on a new machine. Striping/RAID0 is dangerous in this respect - you're increasing your likelihood of volume failure by the number of disks in your stripe. You should only use striped volumes for data you don't care about, or you should stripe over an underlying mirror instead (which is RAID 10).

[SLUG] Seeking recommendations for a video camera
Hi all, Well, our trusty Sony analogue video camera has just bit the dust :( I'm looking for a recommendation for a new one. Our budget is limited to under $1000. I have no firewire adapter on the desktop machine (on which I'd be doing home vid editing). The desktop runs (K)Ubuntu 5.10. Anything that will 'just work' using Kino (for instance) would be preferable (DV raw). I do have a firewire adapter on my laptop, though I've never used it - don't have any firewire devices and don't know HOW to use them :). The laptop runs FC4. Any assistance or advice would be most appreciated.

Re: [SLUG] Greylisting on Postfix
Howard Lowndes wrote: Would anyone like to share their views on any of these solutions, or on greylisting itself. We implemented grey listing about 2 years ago. As I get most of our contact@ mail and since that address is all over the web, you can probably guess what a difference this made. I went from about 300 SPAMs every day (mostly caught by Spam assassin and my mail reader) to around 20. At the beginning, the grey listing was a bit of a pest; some mailers *don't* resend, even for legitimate mail. For example, someone I knew had a dodo.net.au email address. I consistently didn't get her emails, and didn't white-list her because she didn't tell me of the problem. She's since set up her own mail server, so that solves that. This is a problem for businesses though. I can't say whether we've lost bookings or business due to people trying to send us email and us not receiving it. I can hope that such people would call us, but they may not. If most of your new contacts are made from people emailing you; then grey listing could lose you some of those people. On the other hand, I can say that grey listing has saved me hours of looking over my spam folder, to fish out the occasional false-positive. I've been able to use this information to write more courses, do more advertising and even relax a little more. Of course, once we got our SPAM down I got subscribed to a mailing list which I had to be on, and which acted as an open relay... but that was another story. Fortunately it's fixed now. :( Jacinta -- (`-''-/).___..--''`-._ | Jacinta Richardson | `6_ 6 ) `-.
