Migration from RAID1 to RAID5 turned out to be many times easier than I thought 🙄 In general they are 5 simple little wait steps and 1 a beer for courage.

For me, the system has been created RAID array md0 in which they participate 2 sda and sdb disk. I will add a 3rd sdc to them to create RAID5 from 3 disk. In general, this acrobatics is for the scientific purpose of a virtual I have not yet tested it in a real environment, but I don't expect dramas on a real machine when the time comes.

  1. We create the same file system layout as on our other disks – sfdisk -d /dev/sdb | sfdisk /dev/sdc
  2. We are upgrading our current RAID5 array – mdadm –grow /dev/md0 –level=5
  3. We add the new disk to the array – mdadm –manage /dev/md0 –add /dev/sdc . Here comes the thin point that the array is still RAID1 and will not start syncing because our new drive is spare
  4. The most important moment sdc becomes active and synchronization begins – mdadm –grow /dev/md0 –raid-devices=3 . Good time to open your beer if it is not done 😉 Do not interrupt the process under any circumstances!!!
  5. After the synchronization is over, it has to resize the partition because the loss of space in RAID1 is 1 / n and in RAID5 is 1-1 / n

The biggest bonus is that there is no need to restart the system or remove and create additional arrays.

sfdisk -d /dev/sdb | sfdisk /dev/sdc
mdadm --grow /dev/md0 --level=5
mdadm --manage /dev/md0 --add /dev/sdc
mdadm --grow /dev/md0 --raid-devices=3
resize2fs /dev/md0

Good evening 😛

I haven't scratched anything for a long time that I'm on vacation and I'm spending a lot of time testing my new 9600GT video card. True, the 9800GTX is not what I wanted to buy, but the price of this one was temptingly low and I decided to spare the money.. I think it's a good buy. The map exceeded my expectations several times. So far, except for GTA IV, all other games at 1440x900 are running at max with AA & AF 😉 😈 The video card belongs to the company Gainward which is relatively unknown to me. The card has 512MB of DDR3 memory with 256 household bus 😎 generally good performance is 😉 The important thing is that it is actively cooled and carries on a clock, although for now I will refrain, so far the games don't start to lag at me then we'll see I can just change the bottom with one that supports SLI instead of knocking and frying the poor card. I also put Windows on because of her 7 and I can say that the gentlemen from the micro-soft have done great – they removed all idiotic things from the worm that they irritated unnecessarily, the system works stably and most- the important thing for me is to support dx10 to test the optimum on the card. As a final word I can say that 9600GT is a good and cheap solution if you decide to upgrade the old video, for me the difference was huge from 8300 (bottom) to the present 🙂

I look like a kid, I test games a lot, I read which one with which graphics and so on. I scrolled through Devil May Cry 4 great game with great graphics supports dx10 and dx9 modes according to the hardware you have 🙂 I would test to see the difference between the two versions but I forgot, maybe some day I will download it again and then I will write a static on whether dx10 makes sense 🙂

from 2-3 days I'm doing something pretty bad 😈. As you know, I have a little one without an optical device to it, and therefore when folding an OS, it is necessary to reinstall it in an alternative way, ie through the USB port, and because I do not 100 and a shortfall of BGN for a USB DVD just so I can reinstall like a dude when I folded something I bought a flash drive that my Mac is for reinstalled from 2 weeks. I also bought an 8GB for 32 BGN, the rest will be used for beer 😉 I looked at the tutorials and saw 2 disturbing things

1. to make such a flash drive you need to have an optical drive according to this one tutorial which, however, is not quite complete 😉 separately that not every release allows it. immediately followed the question fuck, well, I only have one computer and I don't have an optical device??? There are no such problems with Linux, you just download the iso and unpack it and then with syslinux you write to make a boot reckord and you're ready, so I looked for another way

2. I found similar to the first tutorial but complete with the requirement to have a poppy installed :mrgreen: ебаси хората ами нали целта ми е сега да инстална пък ако старата ми машина не подържа мак какво да правим 😉 както и да е без много много да му мисля закачих мак на персоналния ми комп и о небеса стана 🙂 всичко направих от исото на iAtkos v5 10.5.5 installation flash everything went smoothly isntalria is extremely fast

So far so good, but still the question remains that there is no effective way without being limited by OS or hardware to make an installation flash drive for the Mac 🙂 and in general at the moment I'm thinking of various tricks to come up with a universal way for this purpose in this case everything is on 2 levels

1. Proper unpacking of the DVD with the contents of the axis in question does not hurt at the moment 100% successful

2. booting this level I still have not caught it in general I think to make a package with the files of Chameleon or EFI on Netkast according to depends and then save them I think I will deal a little easier with this level.

In general, at the moment I do not have my successes and failures, if I do not get tired I think I will soon have more serious progress., but it's ugly that when you have a lot of failures and you're not very inspired to continue abe complex sewing 🙂 as long as I've swollen people

Last week we built a local network of a school and launched the Internet through them 2 linksys wrt54gl as usual my expectations were justified by a lot of problems with both routers once again linksys did not disappoint me with their weak software and hellishly sad that they are a subsidiary of cisco 🙂 In general, I have never been biased towards technology, except for hp and linksys, but in both cases I have more than enough reasons to say so.. In general, the problems revolved around the fact that routers lost their settings completely or completely almost every day.. Also from time to time if they have not accidentally lost the settings if they disconnect from their pppoe connection then they did not want to re-hook although their option turned out to be explicitly at 1 min no connection to reconnect. Their power supplies were working. The substation is located in the school yard so there is little electricity or nasty fluctuations in it – excluded quite illogical things. Today I decided to change their software with which they work with some Linux 😉 . There are a lot of projects in general from friends I know on the subject I know are the best Tomato, OpenWRT and DD-WRT. After reading the first and last were with pretty good GUI capabilities and the second was oriented more towards more hardened Linux users 🙂 . I saw it once “the tomato” and in general I know that its capabilities are good but a friend who is well ahead with the matter told me to try the dd-wrt., having previously checked for your router which one is right. In my case, I had to download 2 the file one mini and the other standard, first I went with the mini to unlock the frame and then with the normal file so that everything is fine. In general I can't say how the router works but 100% better than before it is still on Linux 😉 :I can only comment on the software capabilities and they are more than stunning from absolute statistics for all speeds, connection packages, etc. to… options where they are in routers for 1000$ and up really more than a pleasant surprise is all that can pptp server, vlan’s, like, loopback deteckt, the possibility for console work is possible through the gui or through telnet or ssh more than convenient and easy 😉 in general I looked at the software around 20 min and I couldn't fill everything but definitely dd-wrt is more than a good choice. If your router is in the supported hardware do not hesitate to change your old company software 🙂 you will get more than you can use.

Of before 3 days I decided to upgrade the host machine, that is, to replace it with a new one. But apparently he was not quite successful. In general, the machine that was supposed to be the new host is 3200+ from 512 drr @ 400 with my favorite asus bottom 🙁 but it wasn't written. I stop the old machine, transfer the hard drive to the new one and start for the port, switch to a different architecture, I still don't know how to transfer without loss. And I decide to reinstall with my old netinstall CD but it doesn't work I decide it's too scratched. Svealyam new again the same hava I change cables tovati that thing and at one point the screen blinked and my machine crashed 🙄 I comb and there is no one I start to pick up cables ram no one. Fuck! I decided it was a carat video because of the blinking that happened 🙂 I found another video I'm playing another unpleasant surprise- no one is. SUX I found my pci video card from a friend who deals with repairing steigers and I try again none и work thick change ram cpu none. During this yesterday my greasy machine is doing some misery and after a quick cleaning everything is messing with it at least 🙂 The stupid thing is that now I'm back with the old anemic machine and I would like to do various palms streaming havi. Cheers, I'll find some socet a and then 🙂 If someone has a readable one with a DDR memory to whistle I accept offers 😉

ps Sorka for my incompetence, I hope you missed me 😈
