LVM snapshot questions.

by Adam Keck

Hello All, I have several questions about LVM snapshots. o Are snapshots persistent across reboots? If not by default, can they be made to be persistent? o How many snapshots can I have at once? o Is there some in-depth documentation out there on just the snapshot aspects of LVM? I spent about an hour googling for this info, but couldn't find what I needed. Why am I interested in this? Last year I took advantage of one of those occasional Tiger Direct ( shameless plug ;) deals to get myself a 200GB drive for 50 bucks. I am using the drive to backup my machines. Right now I backup once a month by copying the user data from my iBook, my wife's iMac, and my Knoppix laptop to the drive. Each time it comes to about 15GB total. I am beginning to fill the drive, so I want to design a more efficient way of using it with OSS tools. My plan is this: o Acquire a cheap used PIII pc. Install the 200GB drive and Centos (for familiarity's sake, RHEL is one of the distros I use at work) o Make an LVM partition on the drive. o Designate half the drive to data and half the drive to snapshot space. o Rsync every machine weekly. Prior to each rsync, snapshot the drive. o Keep as many snapshots as will fit. Presumably this will be many more "full" backups that I can hold than by just copying stuff to the drive outright. I am downloading Centos right now to test this scheme. I thought I would ask while I wait for bit torrent. Has anyone tried something similar to this? -Adam

Hi, Based on one of our post-meeting pizza discussions last night I thought I would send an e-mail (something I do so rarely). Here is a site that has a good selection of WIFI gear (APs/amps/antennas). I have never ordered from them but they appear to have a good selection of radio gear. http://www.fab-corp.com/ A few ideas to remember: 1) A stronger omni directional antenna (greater db numbers) will improve both your transmit and receive and both are important for range for WIFI. 2) Directional antennas must be aimed at the other radio. You get more gain, but they are usually not the solution if you want to wander your house/deck/yard with the laptop. 3) Amplifiers have downsides; 1) another device to power 2) another device to fail later 3) a good one runs around $200 with both transmit amp and receive pre-amp. 4) Antennas are rated in decibels (db). Most antennas on access points are round 3db - 5db. In terms of signal strength an increase of 3db is a doubling of effective power (Ex 3db to 9db is roughtly 400% stronger). 5) The weakest link in WIFI is usually the card and particularly the internal antenna in the laptop on the far end. 6) You do not succeed unless both devices can both "transmit" and "receive" the other radio. 7) Selection of a feed cable for an external antenna is VERY important. At 2+ghz frequencies a long cable (>1 foot) or a poor quality cable will loose everything you are trying to gain with a better "numbers" antenna. >From a local computer AND radio geek, Joel Desrochers

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We have a WLUG meeting scheduled for Thursday, Sept. 15 at 7:00 PM in the Access Grid room at WPI. I'm not sure of the topic, but if nothing better turns up, I'll start babbling about my most recent USB experience (which started unpleasantly but ultimately had a happy ending), and we can segue from there into whatever topic people wish to discuss. Bring your Linux problems and try to stump the audience. :-) I'll bring my iAudio G3 MP3/Ogg player since a couple of people said they wanted to see it. I had hoped to have it at the last meeting but it wasn't shipped to me in time. Naturally, we'll go out for pizza after the meeting. We can discuss the insanity of looting televisions during a flood crisis, the possibility of adding anti-DRM language to GPL v3, and whatever else we find interesting. See ya then!

Re: [Wlug] SuSE dual [core] frustration.... - update

by Adam Keck

Hi All, I am having much better luck with the SuSE kernel-smp-2.6.11.4-21.8 kernel. The dual core machine boots normally (i.e. without maxcpus=1) and /proc/cpuinfo shows the four cores. Unfortunately, the SuSE's (9.3) particular iteration of the forcedeth module seems to be having trouble with the networking bits of the nforce4 SLI chipset. Rather than dipping into the SuSE kernel-of-the-day development builds, I think I am going to drop in an Intel NIC in order to move forward. I will send an update when we put the machine through its paces. -Adam p.s. I just found a shrink-wrapped Maxell Mammoth cleaning tape and an upwrapped unused Compaq DLT IV tape in a moving bin. I don't need them anymore. I will let the DLT IV go for 15.00 and the cleaning tape go for 5.00. Email me off list if you are interested. I can bring them to the Sept. meeting.

RAID0 = stripping RAID1 = mirroring RAID5 = parity RAID5 suffers on write performance when compared to RAID1, since if you write a small chunk of data, RAID5 may have to actually READ/COMPUTE PARITY/WRITE to all the drives. With RAID1, it's a simple parallel write to each drive. No READ overhead. RAID5 can generally just lose 1 disk from the set without losing data. RAID1 can lose 1/2 the mirror without losing data. How you implement your RAID1 setup across more than two disks is an issue. I choose RAID1 over RAID5 because I only had space for two drives, and I only had an HPT302 with dual channels, so I put one disk on each channel for maximum peformance. If I had more money and a 3ware controller, I probably would have gone for RAID5 on my data, since it has a size/cost advantage over RAID1. I would NEVER go for RAID0 for my data, too much potential for data loss. Even with backups.

In my case, I've got a pair of 9gb SCSI disks, and I currently boot off one. My plan has always been to mirror the two disks so that if I lost one, I could still boot. My data is all on a pair of 120gb IDE drives, which are mirrored, and which have saved me from ugly restores, because I noticed that one disk had dropped out and I was able to just re-mirror without any major impact.

Stream rippers

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI gang, Does anybody have a favorite stream ripper that they'd like to recommend? FYI, a stream ripper (as I've very recently learned) is a program which "listens" to a streaming audio broadcast and saves that information on your hard drive. Streaming audio broadcasts are available on shoutcast.com and icecast.org, and probably many other places. I'm using a program called 'streamripper' (strangely enough) which I found at http://streamripper.sourceforge.net/. I'm wondering what others might be using. It has a feature where songs can be saved as individual .mp3 (or .ogg) files, or the whole stream can be saved in one file. I've downloaded these songs into my portable MP3 player for later enjoyment. There seems to be some controversy about the use of such programs. Frankly, I don't see it as any different than holding a microphone in front of the radio. Granted, the quality is much better with a ripper. Prior to learning something about stream rippers, I had been using the Ogg encoder output feature of xmms while xmms was "tuned" to a streaming audio broadcast. As I understand it, this involves taking the stream source (an MP3 stream generally) and re-encoding it into the Ogg format, which technically involves a loss of quality (can I hear it? I'm not sure...).
