Re: [e-smith-devinfo] adding a 2nd hard drive
Lee Roy: I've been thinking about this problem for a few weeks, since first being introduced to the e-smith product. As the installation process always destroys the contents of the hard drive, it is possible to lose your data if for some reason you have to reinstall. Making a tape backup or dumping the data to a client machine is some help, but it won't get your recent data back, and recent may be quite a few days if you or your client isn't meticulous about doing backups. (and who is?). And that data loss could be disastrous, so a better solution is a good idea. I've got a preliminary how-to posted on the e-smith site (How to use an Adaptec Raid controller... in the hardware category) that explains the bare bones of what I do, but I'm going to be updating that in the near future to add some new discoveries. Basically, the idea is to put a second hard drive, or better yet, a raid array inside the box, and store your data on that. If you ever have to reinstall the e-smith server, you're not going to wipe out your data; you'll just remount your data drive(s) on the boot drive's directory tree. I've talked this over with some of the e-smith staff, and they don't seem to have or see any problem with it, although (as tech people always say) "we'll try to help you if you have any problems, but we can't *GUARANTEE* that we can get you back up and running." I guess that tiny margin, between almost certainly get back up and running and cannot guarantee it, is where a tape drive or some other form of backup comes in. The idea is two-fold: 1. move the entire contents of the /home directory to the data drive; and 2. make occasional updates of the reinstallation diskette. I have done this successfully with an Adaptec SCSI raid controller (expensive), an Adaptec IDE raid controller (medium cost) and a Promise Fastrack 100 IDE raid controller (now we're talking cheap), and I'll cover the details in my next how-to. But it's really pretty simple, and straightforward. Plus, unlike the Linux software raid situation, where info about recovering from a drive failure is either nonexistent or confusing or inapplicable, if you use one of these cards in hardware mirroring, recovery is just about automatic. Finally, once you have moved the /home directory over to the new data drive, the server doesn't know the difference, acts perfectly normally, and all features will work as usual. But now, you have some additional protection.

Hi Tom, so if I understand you want to have add a second drive or raid array to hold /home. Definitely possible. Why do you feel this is a benefit over a standard install? Again, if I understand your goal the second hard drive/raid would need to be linked so e-smith would treat it as a normal install. As such the only small benefit I see is you have two hard drives in use so if the first drive fails the theory is your /home drive is left unaffected. Isn't this a similar benefit a s/w raid 1 or h/w raid implementation would provide? -- Darrell May DMC NETSOURCED.COM http://netsourced.com -- Please report bugs to [EMAIL PROTECTED] Please mail [EMAIL PROTECTED] (only) to discuss security issues Support for registered customers and partners to [EMAIL PROTECTED] To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Archives by mail and http://www.mail-archive.com/devinfo%40lists.e-smith.org

Re: [e-smith-devinfo] adding a 2nd hard drive
Hi Darrell: I think this is a benefit over a standard install for these reasons: 1. Single hard drive will inevitably fail -- sooner or later. 2. Backups through tape or client dump-to-disk won't get done often enough. Much of the time, they won't get done at all, or be done more often than weekly. I think this is made worse by the reliability of Linux. 2. Software mirroring can help, but it doesn't protect against making a stupid mistake and thereby rendering the machine unbootable. Also, no one I've asked can tell me how to successfully recover from a crashed software-mirrored disk. Probably there is a method, but no one seems to know what it is, and if it exists, it is probably somewhat complex -- not the thing you could talk your client through via telephone. 3. Hardware mirroring is now cheap, simple, and easy to recover from or just keep running on one drive until fixed. Unfortunately, there does not appear to be any way to install e-smith to an inexpensive hardware mirror or other type of raid array. The promise card in my earlier post is less than $100, making it only slightly more expensive than software mirroring, and much easier to work with. 4. There are apparently some hardware raid controllers on the supported list, but they are not available through normal reseller channels, and tend to be very expensive, and to require expensive SCSI hard drives. So, while these are an option, they aren't going to be cheap. 5. Even if you could install directly to a hardware raid device, if you screw something up while working from the command line, you may end up with a machine that won't boot anyway. (For instance, the Adaptec IDE raid rpm has a flaw that renders the machine completely unbootable). I know you can still (probably) recover from that, but again, you won't be able to talk your customer through that process over the phone, and your precious data is very much at risk and unavailable until you can get there in person. I think I've convinced myself of the benefits; I'm not sure if you or anyone else agrees. Regards, Tom Darrell May wrote: > "Thomas E.

The 3ware Escalade 6200 is a two-channel true hardware RAID controller (the Promise card you listed isn't really), and it sells for about $129 on pricewatch. It's on the e-smith HCL, addressing point 4 of your message, and it doesn't require SCSI hard drives. Another possibility is the ARCO DupliDisk arrangement. It's nowhere near as nice as the 3ware, and it costs at least as much, but it's a bit more transparent. Both of these would give you a hardware RAID 1 implementation. What you propose (separate drives for system and data, but neither drive mirrored or anything--right?) would do nothing to preserve the data (it's still on just one drive, which can fail), and would add another point of failure (that way, either drive can go, and take down the system).

Re: [e-smith-devinfo] adding a 2nd hard drive
Dan: As you will note from my msg to Darrell, I'm going to try the 3ware, but I still have a nagging uneasiness with it, as a misstep or defective RPM can blow away the boot drive array and the data with it. Your point of view: If you mount a raid on /home, might as well install the whole system on it--again, better to have fault tolerance for the whole system than just for the data. isn't what I'm feeling, especially after repeatedly reinstalling the Adaptec IDE RPM, and seeing the system blown away and refuse to boot thereafter. You will know much better than I do, but between the use of the separate /home directory on a raid array, and an up-to-date reinstallation diskette, am I going to need any reconfiguration after a reinstall of the e-smith (assuming I remember to pull the IDE cables to the data drives)??? Now I know that certain hand-customizing won't survive this kind of reinstall, but assuming the server is vanilla except for the /home remount, where will I be? Thank you for jumping in, BTW, and I hope you see my point: with a destructive install, if a re-install is needed, it is *NOT* better to have fault tolerance for the whole system than just for the data. Now, since I've been trying to become a partner for several weeks, and haven't yet sampled your tech support, maybe you see it differently, and don't often find situations where damage can't be repaired and a reinstall is needed. I'm coming from a different world, where a reinstall fixes (most) everything ;-). Regards, Tom Dan Brown wrote: > Quoting "Thomas E. Keiser" <[EMAIL PROTECTED]>: > > > 3.

Ah, OK, I think I better understand your concern now. You're right; if you're thinking "reinstall to fix most strange problems", you'd be better off with /home on a separate drive/array. Reinstallations don't seem to be needed very often, though. > survive this kind of reinstall, but assuming the server is vanilla except > for the /home remount, where will I be? You should be pretty well set in that case. You'd still need to redo whatever changes you made to mount /home from a separate drive, of course. > install, if a re-install is needed, it is *NOT* better to have fault > tolerance for the whole system than just for the data. I still don't agree here--fault-tolerance for the whole system is still better than fault-tolerance for the data only. However, to address your concern as well, you'd be looking at two separate arrays (certainly possible on a 3ware 6400/6410). > partner for several weeks, and haven't yet sampled your tech support, Just to be clear--it isn't "my" tech support, as I have no connection with e-smith other than as a user. I know a little bit about the system, and I've written some how-tos, but that's just from my general interest. > it differently, and don't often find situations where damage can't be > repaired and a reinstall is needed.

My thinking was that, AFAIK, "upgrade" installs the appropriate versions of everything on the e- smith CD, replacing whatever you have installed. I don't really know what it does with other software.

I Well, it certainly shouldn't format the drive. Try this sometime: install a clean 4.1.2 system, and then upgrade php, samba, or something else. Then do an "upgrade", and see what version of whatever you upgraded is now installed. If the "upgrade" restores it to the original version, I think that'd be a good sign. -- Dan Brown, KE6MKS, [EMAIL PROTECTED] "Meddle not in the affairs of dragons, for you are crunchy and taste good with ketchup." -- Please report bugs to [EMAIL PROTECTED] Please mail [EMAIL PROTECTED] (only) to discuss security issues Support for registered customers and partners to [EMAIL PROTECTED] To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Archives by mail and http://www.mail-archive.com/devinfo%40lists.e-smith.org

They are inexpensive and available to resellers. Here is the distributor list: http://www.3ware.com/order/northamerica.shtml As a reseller, contact 3WARE directly and sign-up as a Channel Partner online. They offer 'eval' units to test for 30 days. Once you try one you'll probably change your mind and implement 3WARE h/w raid. :) Also see Eric Womack's HowTo on the contrib site. :) -- Darrell May DMC NETSOURCED.COM http://netsourced.com -- Please report bugs to [EMAIL PROTECTED] Please mail [EMAIL PROTECTED] (only) to discuss security issues Support for registered customers and partners to [EMAIL PROTECTED] To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Archives by mail and http://www.mail-archive.com/devinfo%40lists.e-smith.org

Darrell: Thnx for the info on 3ware; I've ordered one of each, and will certainly give them a fair trial. But one thing I said in my earlier post still gives me pause: 5. Even if you could install directly to a hardware raid device, if you screw something up while working from the command line, you may end up with a machine that won't boot anyway. (For instance, the Adaptec IDE raid rpm has a flaw that renders the machine completely unbootable). I know you can still (probably) recover from that, but again, you won't be able to talk your customer through that process over the phone, and your precious data is very much at risk and unavailable until you can get there in person. So, while hardware raid is nicer than software raid, it is still vulnerable as a boot drive array in ways that it wouldn't be if it were just a data array.
