I collected bad experiences with backing up with the kernel on the local side. I since then prefer to have another box managing the filesystem than the one i'm backing up

"rsync -xva" does wonders ... the "-x" flag tells it not to cross filesystems, so it won't try to back up stuff like /proc

The new server went in last night ... a replacement for the replacement.
It's working nicely, and it even has a hardware RAID card, so if I lose a disk it's just a matter of tossing a new one in. But as I've said many times before, disaster recovery and backup are two different issues.

I might just throw more disks into my home server and my Internet server, and back them up to each other.

Subject: automatically shutting down winXP HOME remotely

[Reply] [ReplyQuoted] [Headers] [Print]

at work, we have two computers (one linux, one xp HOME) hooked on an UPS, but only the linux server has direct contact to the ups. so, when the lights go out and the linux cleanly shuts down, the xp HOME computer doesnt get notified to shut down properly. easy, i thought, just "net rpc shutdown -f -I ipaddress -U admin%pass" the sucker and off he goes, but no, doesnt work. WERR_OK is the error i get...

then i thought, well, lets use good old telnet, at least HOME comes with a telnet server. but no, admin is not allowed to telnet to the box, because he is not in TelnetClients group, which does not even exist on this machine....

so, someone saved a few bucks with buying a cheaper XP and now i am wasting time (and therefore their money) with finding a solution for the simple task of automatically shutting down winXP HOME remotely

anybody got a solution or a hint?

Speaking of fucker, is there a single program for linux that burns DVDs even slightly reliably?
Preferably, I wanna try burning at slow speeds. Suggestions?

Oh, hey JONG. Since this is the Linux room and you're asking a WinXP question. Post nekkid pics of your gf and we will give you the answer. Or not.

I always had good experience with growisofs, but I think that most distros replaced it with wodim. So you might try that as well.

I'm not sure, but I mean that the dvd+rw-tools are shipped with dvdrecord these days. So that maybe an other alternative.

So Ford.. you could probably help me with this now. Or maybe someone else??
I have a machine with two new 1 TB SATA hard disks.. and I am trying to install Ubuntu Server 9.04.. I want software RAID 1 across the disks, LVM, and three partitions (on each disk).. root, swap, and home. I never used linux LVM before, so I am not sure if the trouble is me or the LVM. The first thing I tried was making a volume group and adding both disks to it.. but this does not seem like the way it is done with this lvm. Any hints as to what I should do in what order?

I'm assuming that you've already discovered that you have to do /boot as a RAID-1 set across all physical disks, preferably on the first partition? After that, you can make the remainder of each disk another RAID-1 set, and then make the whole set a PV. Then you create a VG in the PV, and an LV in the PV.

Ford has more recent experience than I do with regard to migrating an existing system into RAID+LVM, however. I haven't done anything that brave lately

I haven't really figured anything out yet. In the past, I made /boot a raid1 set, and / a raid1 set.. and I didn't bother with LVM. And yes, /boot is always first. But Ubuntu Server 9.04 install gives you the option of using LVM on one disk, no LVM.. or.. "good luck you're on your own"... There is no guidance as to how to set up a RAID at all with the LVM. Fedora made setting up a RAID1 easy.

Agreed on that ... Fedora/RedHat/CentOS makes this kind of thing very easy.
I don't know how to do it in Ubuntu at install time. I've got it running at home now, but with hardware raid :)

So anyway, you want /dev/hda1 and /dev/hdb1 to be a raid-1 set with /boot on it, and then you want /dev/hda2 and /dev/hdb2 to be a raid-1 set with an LVM PV on it. After that's configured, you can put two LV's in that PV, one for root and another for swap (and one for /home if you want that in a different volume).

This is assuming that you have enough room in the box to add more disks later, of course. Without that there's not much point in going LVM in the first place.

Well.. this is the new cownow machine. When I had a pair of 250G disks I was perfectly happy to have just /boot and root. But I was kind of thinking that with this new pair of 1TB disks, I don't really want just one huge file system. (I am not counting swap, which of course is there as well). I am kind of in a hurry to get this machine installed, so at first I thought, well, it is so much more space than I will use for a long time (I am only at 25-30 gigs right now), so I will just chop it up as let's say 100MB /boot, 100GB root, 8GB swap (I have 4GB RAM), and the rest /home. That allows more than enough space for everything and I will not have to worry about it for a long time, given the usage of the machine not being that hardcore... But when I went to do the installation, Ubuntu Server installation seemed to be making LVM easy and pushing me toward it. But now that I see it is going to be a whole learning process, I think I am going to go back to my original plan and just do a straighforward RAID.. manually creating the four partitions, matching on each disk.. as RAID volumes, then setting them up as RAID1, and installing... Since I currently use 30GB for everything, I figure 100GB root and approx 892GB /home ought to be just fine for a very long time.

The secret is to download the alternate install. The regular gui install won't let you do it.
The alernate one is text based, and part of the install process, lets you make raid partitions and then make a raid device and then a filesystem on which you can then install, and it all works.
I didn't try the LVM stuff, but it lets you do that too.

Migrating insane pain in ass, you're better off starting from scratch if you can, but it's doable.
