Re: [gentoo-user] How to make a backup of my gentoo installation
Hi Damian, by the way rsnapshot is a more sophisticated tool to back up your root file system. it is based on rsync, but the bright idea behind is that it creates a history (hourly, daily, weekly, monthly) with copying the hole system only one time. Maybe this is what you preferably want.

You mistakenly set your system up as a 32 bit and you are changing it to a 64 bit ? If that is correct, I think you need to reinstall. There may be other threads you can search for but from what I have read, I think a reinstall is going to be recommended. I'm just a 32 bit user here but I don't think it is that easy to switch from 32 to 64 bit. I would check the forums, archives for this list and maybe some docs on the Gentoo site. The Gentoo wiki may be of help too. I wouldn't get my hopes up that this "switch" is that easy. If you don't get a guru to reply soon, may want to try starting a new thread. Dale :-) :-)

Re: [gentoo-user] dev-java/sun-jdk-1.6.0.11 Failed to unpack
Progress: I've discovered that athlon64 is a valid gcc make flag, so I changed it back. I've also discovered that the /etc/make.profile symlink was pointing at the x86 default-linux profile set, not the amd64 profile. I'm attempting a recompile now with the symlink changed, and hopefully this will fix my problems. I wonder if this latent error is not about to cost me a whole bunch more though. Is there anything I should do with the emerge command or any other command in order to correct this profile problem?

Re: [gentoo-user] dev-java/sun-jdk-1.6.0.11 Failed to unpack
Thanks, That only adds more questions. My environment is amd64. It appears to have downloaded the i586 binary. Surely this is incorrect? my make.conf file contains the line CFLAGS="-O2 -pipe -march=athlon-xp", which should trigger the 64 bit binaries to be downloaded and acted upon. The CFLAGS variable was previously set to "-O2 -pipe -march=athlon64", and I don't think that athlon64 is a valid gcc compile flag, but the response was the same with this set of CFLAGS variables too. Also,since I changed the CFLAGS variable, is there anything I need to do in compilation to correct any errors resulting from the original (I believe invalid) variable? Any suggestions gratefully received.

One disadvantage of software RAD would be that partition management tools like parted may not (or WILL not) do resizing on a software RAID but will (or should!) on hardware RAID. If you go with software RAID and later decide that a partition needs to be moved, resized, etc., then you may not be able to do it. I would suggest finding a good, if inexpensive, hardware RAID card or possibly play a bit with the RAID stuff on your motherboard to see if parted can work with it. Just some thoughts. Cheers, Mark

That helped a lot as far as noise goes. With the side off, it can be a bit noisy but with it on, there is almost no noise. It dampens the metal so that it can't let the vibrations of the noise through the sides. My top and bottom are pretty strong anyway so they do all right. Dale :-) :-)

Therefore I can say with certainty that it's not the change from ide/hdX to sata/sdX. If I recall, I encountered the same boot issue back when I only had an IDE drive and attempted to use 2.6.26. At that time I wasn't concerned, so didn't attempt to determine what was wrong. As additional info, I've replace my .config with arch/x86/configs/x86_64_defconfig and have the same problem. Cheers!

Loading modules ... libata ... ... scsi_wait_scan ... ... ahci ... ... sg ... ... ehci-hcd ... ... usb-storage ... ... uhci-hcd ... ... ohci-hcd ... Activating mdev With the 2.6.27 kernel, after displaying "Loading modules" and its related messages, the "Activating mdev" message never appears and the boot process is stopped. Anybody know what's wrong? FWIW, the mobo is an ASUS M2A-VM HDMI with an AMD64 X2 5000+ CPU and 8GB ram. The 2.6.25 kernel is new as I've just upgraded from an IDE HD to SATA. The 2.6.27 configuration was generated from the 2.6.25 configuration using "make oldconfig". Regards, David

[gentoo-user] How to make a backup of my gentoo installation
... using rsync. Hello, Finally I got a (less than perfect but) functional gentoo installation and I would like to backup my root directory to an external hard-drive. But I have a doubt regarding the options to be passed to rsync. I think this command should perform what I want: rsync -a --delete --relative --exclude '/home' / /mnt/wd-backups/ But I would like to ask you if this is correct. Best regards, Damian.

Alright, thank you for your help. I got it running late in the night

[gentoo-user] Booting from dmraid
Hello, I have followed this guide: http://en.gentoo-wiki.com/wiki/RAID/NVRAID_with_dmraid and practically everything is working. However, I want to make things better. I have used genkernel (with a custom config) because it is very easy to set up dmraid apparently. I am not happy with this because genkernel generates a 21MB initrd that runs some autoload scripts that load modules for every hardware device I don't have. I wonder why can't I statically compile dmraid support in the kernel and not require an initrd file. Is that possible? Thanks, -- Aram Hăvărneanu

Even when I had three drives in my case, I couldn't hear them because of the CPU and other fans running. I guess either my drives were quiet or you may be water cooling or something. I haven't had a problem with drive noise in ages. I do have a server case so heat has never been a issue for me. Right now my case temp is 73F, my CPU is 90.5F. One hard drive is at 77F and the other is at 84F. The one running at 84F is the currently active one with my OS. The other is just sitting there spinning. Hope that helps. Dale :-) :-)

Personally I use an external hard drive for storing my music collection and video files (movies, series, etc). I haven't had any problem while watching videos or listening music from the external hard drive. But I guess for other purposes it might not be the best solution.

However, I tried disabling adblockplus and that was no help. What I don't understand is why the site would display just fine in Opera, but not in Firefox.

Spinpoints have the reputation of being a good mix between cost effectiveness, speed and noise. Do you think that would result in a greater speed increase than another Seagate and RAID0? No. Stroller.

The factors to consider are cost, capacity, speed, noise, and heat. ... but $200 for 300GB is pretty expensive I don't find your criteria well-defined - fast, cheap (large) & reliable, pick any two. If the factors were ONLY cost, capacity, speed, noise, and heat, then I would say throw away your old hard-drive & RAID 0 across cheap 1TB drives, which are c £65 each at the moment. In RAID 0, however, the 0 stands for how much data you get to keep in the event of drive failure, and most of us don't want that. I also don't see your old drive as redundant. Haven't you considered just mounting an additional drive at /media/ video, or /var or /home or wherever? I personally don't find hard-drives to be significant contributors to a system's noise. There are too many fans in any of my machines to notice the difference made by an extra disk crunching away. Additionally, in typical PC systems with capacity for only 4 (maybe 6, these days?) ATA drives, I don't find heat to be a problem. I'm sure I've read articles saying how heat is the biggest contributor to drive- failures, but I have two machines in my airing cupboard here [1], each stuffed as full of disks as possible (3 in one, 4 in the other PC) and have never had a failure on any of them. One system is at least 4 years old, probably more like 6, the other at least a couple. In a later post you say drive throughput may be an issue for you, which I did not really find clear initially. I would personally consider a pair of two of the cheapest new drives I could find (probably 80gig @ £22 each inc VAT or 160gig @ £28) and RAID 0 them. Others may advise if the partition scheme which immediately occurs to me - 3 partitions: swap, /tmp and /mnt/video/my_tmp - is wise. RAID 0 will be twice as fast as any single drive, but for me I wouldn't need a large volume in that configuration, as I wouldn't keep anything important on it, nor the root of my system, nor anything that would need restoring in the event of a failure. Stroller. [1] US readers: I'm not sure if you use the same expression. In the UK the "airing cupboard" is the small cupboard in which the home's hot water tank sits. I guess you may keep the hot water tank in a large basement, but British homes have less room, so it is confined in a small cupboard which gets very warm indeed. Consequently it is used to dry bath towels after use, and hence the cupboard's name.

I haven't considered RAID for data security because I'm backing up critical system and data files across physical locations. I figure that's better because I'm protected in case of fire or theft. It would be nice for the system to stay up in the case of a hard drive failure, but there are so many other components that could fail. >> Should I get another identical drive and set up RAID, or will >> that create too much noise and heat? > > A RAID won't cause more heat or noise than a second drive but it will also How much perceived noise does a second drive create? > I'd say if you don't care about redundancy, you should go for a single 1TB > disk.

I have had zero flash problems since then. Of course, we don't know if the OP uses 64-bit gentoo or not. Also, if you're using Firefox add-ons such as flashblock or adblockplus, I would try disabling them. Sometimes they interfere in the rendering of the page even when you've whitelisted the site.

LVM's support for mirroring and striping is exceptionally crude to say the least. You will also have problems if your stripes do not align with the underlying volume. Seeing as LVM is designed to make volume management easier and RAID is designed to provide redundancy, it is best to completely dispense with the mirror/stripe "features" of LVM and leave that to the thing that does it best - RAID - while letting LVM do what it does best - making your life infinitely easier with volume management. Plus, most built-in so-called hardware RAID solutions are utter crap and nothing worth the silicon they are built on. Linux software raid is many times better. Rule of thumb is that if the OS can see the underlying volumes that make up the RAID, you do not have real hardware RAID. You instead have something else that a marketing person decided would be cute if it were called hardware RAID.

The factors to consider are cost, capacity, speed, noise, and heat. So you don't care about security, right? With security I mean redundancy (RAID1,5,10,...) Should I get another identical drive and set up RAID, or will that create too much noise and heat? A RAID won't cause more heat or noise than a second drive but it will also not necessarily solve your problem: RAID0 gives you the capacity of both drives combined and a lot of speed but if one of the disks dies, all data is lost. RAID1 spends the complete capacity of one of the drives for redundancy. RAID5 needs three drives (so it doesn't fit into your cost, noise and heat requirements), gives you the capacity of two and enough redundancy to loose one disk. However, its write performance isn't extremely high. Should I get rid of my current drive and get a new drive, or will that not be much faster? Your drive is good, why should you scrap it? Velociraptors are reputed to be very fast, but $200 for 300GB is pretty expensive and 1TB would require 4 drives which I think would create a lot of noise and heat. There are two "brute force" ways for an HDD to get faster: You increase their rpm or you increase their storage density (so that in one rotation, the r/w head can read/write more data). The latter has the advantage that it causes no additional heat or noise but more rpm give you lower access times. I'd say if you don't care about redundancy, you should go for a single 1TB disk. I'd prefer a Samsung Spinpoint F1. Spinpoints have the reputation of being a good mix between cost effectiveness, speed and noise. Then I would use it (and the older disk) in an LVM volume group. LVM also supports mirroring (like RAID1) and striping (like RAID0) on a per-volume basis. That means that you could keep most of your data somewhere on the TB disk and still experiment with mirroring and striping using both disks for partitions which need more speed or more security.

That's why I suggested them :-) I use them a lot, especially when I have to
run the same set of commands on 15 different hosts, then I do something like:
for I in $(seq 1 15) ; do scp package.tar.gz a...@host${i}.domain.com ; done
for I in $(seq 1 15) ; do ssh a...@host${i}.domain.com tar xvzf
package.tar.gz ; done
You can get real cute and put the host name and commands into files (one
command/host) per line and run it all as two nested for loops:
while read -u hostfile HOST ; do while read -u commandfile COMM ; do ssh
a...@${host} ${COMM} ; done ; done
That's off the top of my head, it'll need some parenthesis to make it actually
work otherwise bash gets confused with too many ";"s but you get the idea. A
running ssh-agent in these cases is recommended too :-)

Thank you all for your suggestions. I think think that:
md5sum -c token{a..z}.md5sum and
md5sum -c token*.md5sum are the easiest on this occasion, although Alan's
last two commands are indeed "insanely useful"! ha! They will be saving me
hours of typing in the future. :)
