Raid 10 repair question
by o1bigtenor 20 Feb '15

20 Feb '15

Greetings I have been running a raid 10 array for almost 3 years. Last September on a reboot (forced by Firefox and kernel memory interaction problems) came up with one of the drives being listed as DOA. The raid array has continued to run on 3 drives although on reboots there is much complaining from whatever in the boot up process. I had the replacement drive sent to me and today I installed the drive. I was under the assumption that the raid array would rebuild itself upon startup with a new drive (4th out of 4). This did not happen. I am running Debian Jessie (testing) and have the whole time in question. I can mount the array and it is visible. I'm looking at backing up the array (on blu-ray discs) but as I'm now to circa 45 GB of data and I was at about 22 GB when I last did a backup this is going to be a momentous event. How do I ask mdadm to include this new drive into the array? (Without borking everything!! I have found lots of instructions on how to create but none in an hour of trying different search phrases on how to rebuild or how to cause the array to rebuild itself. I have only been able to find instructions for when the array is totally sick and I'm not there (yet - - - grin!) but I don't want to wait until another drive craps out to get things going.) TIA Dee

RAID and IX-2-dl
by D. Hugh Redelmeier 20 Feb '15

20 Feb '15

I just bought a LenovoEMC / IOmega IX2-dl NAS box (cheap, of course). It has a pair of WD Green 2T disk drives. The supplied firmware is Linux, of course. With a pretty face. /proc/cpuid says "Feroceon 88FR131 rev 1 (v5l)" which I think is an unfortunately old ARM family. It has 256M of RAM. The kernel is "2.6.31.8". It offers me RAID 1, RAID 0, and "none". I don't think that I want either RAID and I'm not sure what "none" is. I don't want RAID 1 because It doesn't give me much reliability improvement for the price (halving the space) and it doesn't give me any speed improvement. I don't want RAID 0 since it gives me less reliability than no RAID. I want two different filesystems so that when one goes south, the other isn't lost. Any advice on how to lightly prod this system to do what I want? Here's some configuration information. /etc/fstab doesn't mention the hard drives First, here's how it looks with the RAID1 setup. lsblk(8) says. (This command is new to me. I think that I like it): NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 680.4M 1 loop /mnt/apps loop1 7:1 0 8M 0 loop /mnt/etc loop2 7:2 0 100K 0 loop /oem sda 8:0 0 1.8T 0 disk ├─sda1 8:1 0 20G 0 part │ └─md0 9:0 0 20G 0 raid1 │ ├─md0_vg-BFDlv (dm-0) 253:0 0 4G 0 lvm /boot │ └─md0_vg-vol1 (dm-1) 253:1 0 16G 0 lvm /mnt/system └─sda2 8:2 0 1.8T 0 part └─md1 9:1 0 1.8T 0 raid1 └─6366c931_vg-lv163c50af (dm-2) 253:2 0 1.8T 0 lvm /mnt/pools/A/A0 sdb 8:16 0 1.8T 0 disk ├─sdb1 8:17 0 20G 0 part │ └─md0 9:0 0 20G 0 raid1 │ ├─md0_vg-BFDlv (dm-0) 253:0 0 4G 0 lvm /boot │ └─md0_vg-vol1 (dm-1) 253:1 0 16G 0 lvm /mnt/system └─sdb2 8:18 0 1.8T 0 part └─md1 9:1 0 1.8T 0 raid1 └─6366c931_vg-lv163c50af (dm-2) 253:2 0 1.8T 0 lvm /mnt/pools/A/A0 mtdblock0 31:0 0 504K 0 disk mtdblock1 31:1 0 4K 0 disk mtdblock2 31:2 0 4K 0 disk df(1) says: Filesystem 1K-blocks Used Available Use% Mounted on rootfs 51200 4216 46984 9% / /dev/root.old 11339 3185 8154 29% /initrd none 51200 4216 46984 9% / /dev/md0_vg/BFDlv 4128448 714776 3203960 19% /boot /dev/loop0 691776 619873 71903 90% /mnt/apps /dev/loop1 7657 1010 6238 14% /mnt/etc none 7657 1010 6238 14% /etc /dev/loop2 128 128 0 100% /oem tmpfs 24776 80 24696 1% /run tmpfs 5120 4 5116 1% /run/lock tmpfs 49540 0 49540 0% /run/shm /dev/mapper/md0_vg-vol1 16493480 975280 15350636 6% /mnt/system /dev/mapper/6366c931_vg-lv163c50af 1902053516 202188 1901851328 1% /mnt/pools/A/A0 /dev/mapper/6366c931_vg-lv163c50af 1902053516 202188 1901851328 1% /nfs/Backups /dev/mapper/6366c931_vg-lv163c50af 1902053516 202188 1901851328 1% /nfs/Documents /dev/mapper/6366c931_vg-lv163c50af 1902053516 202188 1901851328 1% /nfs/Movies /dev/mapper/6366c931_vg-lv163c50af 1902053516 202188 1901851328 1% /nfs/Music /dev/mapper/6366c931_vg-lv163c50af 1902053516 202188 1901851328 1% /nfs/SharedMedia /dev/mapper/6366c931_vg-lv163c50af 1902053516 202188 1901851328 1% /nfs/Pictures After I switched from RAID1 to "none": NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 680.4M 1 loop /mnt/apps loop1 7:1 0 8M 0 loop /mnt/etc loop2 7:2 0 100K 0 loop /oem sda 8:0 0 1.8T 0 disk ├─sda1 8:1 0 20G 0 part │ └─md0 9:0 0 20G 0 raid1 │ ├─md0_vg-BFDlv (dm-0) 253:0 0 4G 0 lvm /boot │ └─md0_vg-vol1 (dm-1) 253:1 0 16G 0 lvm /mnt/system └─sda2 8:2 0 1.8T 0 part └─md1 9:1 0 3.6T 0 linear └─529a853a_vg-lv1ac0e3be (dm-2) 253:2 0 3.6T 0 lvm /mnt/pools/A/A0 sdb 8:16 0 1.8T 0 disk ├─sdb2 8:18 0 1.8T 0 part │ └─md1 9:1 0 3.6T 0 linear │ └─529a853a_vg-lv1ac0e3be (dm-2) 253:2 0 3.6T 0 lvm /mnt/pools/A/A0 └─sdb1 8:17 0 20G 0 part └─md0 9:0 0 20G 0 raid1 ├─md0_vg-BFDlv (dm-0) 253:0 0 4G 0 lvm /boot └─md0_vg-vol1 (dm-1) 253:1 0 16G 0 lvm /mnt/system mtdblock0 31:0 0 504K 0 disk mtdblock1 31:1 0 4K 0 disk mtdblock2 31:2 0 4K 0 disk Filesystem 1K-blocks Used Available Use% Mounted on rootfs 51200 4264 46936 9% / /dev/root.old 11339 3185 8154 29% /initrd none 51200 4264 46936 9% / /dev/md0_vg/BFDlv 4128448 714776 3203960 19% /boot /dev/loop0 691776 619873 71903 90% /mnt/apps /dev/loop1 7657 1013 6235 14% /mnt/etc none 7657 1013 6235 14% /etc /dev/loop2 128 128 0 100% /oem tmpfs 24776 80 24696 1% /run tmpfs 5120 4 5116 1% /run/lock tmpfs 49540 0 49540 0% /run/shm /dev/mapper/md0_vg-vol1 16493480 975516 15350400 6% /mnt/system /dev/mapper/529a853a_vg-lv1ac0e3be 3804366528 200884 3804165644 1% /mnt/pools/A/A0

Fw: [Cryptography] Lenovo laptops with preloaded adware and an evil CA
by William Muriithi 20 Feb '15

20 Feb '15

‎Evening, Forwarding this to this list as I am aware thinkpad is popular. Looks though like Lenovo is shipping a really dirty adware How can they have fallen for this? Regards, William Original Message From: Christian Barcenas <christian(a)cbarcenas.com> Sent: Thursday, February 19, 2015 9:47 AM To: cryptography(a)metzdowd.com Subject: [Cryptography] Lenovo laptops with preloaded adware and an evil CA -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 There's some interesting buzz online [1][2][3] about "Superfish", a bit of adware that Lenovo has apparently been preloading on some of its computers over the past few months. While preloaded adware is bad enough, Superfish does something even worse: to allow itself to MITM SSL-/TLS-protected web traffic, it installs a CA into the Windows trusted root certificate store. This CA is apparently pre-generated and its corresponding private key comes with every installation of Superfish. Furthermore, uninstalling Superfish does not remove this CA, so all users running Lenovo's tainted Windows installation are affected, even if they took the time to uninstall Superfish. A user on Twitter has apparently forged a certificate for Bank of America's online banking system [4] and I expect that we will see more of these shenanigans to come to light over the next few days. According to a thread on Lenovo's customer support forum [1], they are no longer pushing this adware on customers and are asking the authoring company to push a fix for this ASAP. Mozilla also has an issue on their tracker to mark the offending cert as "untrusted" in NSS. [5] Thoughts?

Volunteers for Open Source Comes to Campus on Feb 28, 2015
by Dawn Walker 19 Feb '15

19 Feb '15

Hi all, My name is Dawn Walker, I am a Graduate Student at the Faculty of Information at UofT. I’m helping run a free event to introduce students to free/libre/open source software on February 28, 2015 at University of Torontocalled Open Source Comes to Campus in conjunction with OpenHatch <https://openhatch.org/>(https://openhatch.org/) We're looking for people to help mentor attendees in a variety of ways as they learn how to contribute to open source projects: * Instruction <https://openhatch.org/wiki/Open_Source_Comes_to_Campus/Curriculum>on topics like open source community norms, issue trackers, IRC and git * Participation on a Career Panel <https://openhatch.org/wiki/Open_Source_Comes_to_Campus/Curriculum/Career_Pa…> * Lead a contributions workshop <https://openhatch.org/wiki/Open_Source_Comes_to_Campus/Curriculum#Contribut…>around a specific project (in this case potentially Open Street Map!) * Or, volunteer to support attendees throughout the day! The event run from 10am - 5pm, with coffee, tea and socializing for a half hour beforehand (Mentors don't need to show up at 9:30am sharp, but should be there by 9:45, we will also provide a lunch!). Instructors with a variety of backgrounds are welcome: while it's great if you have tons of experience using git and setting up development environments, we're also looking for people who've been involved with open source as non-programmers, who know a bit about picking bugs and submitting patches, or who just like to talk about their experiences with open source. Here are links to find out more about the Event <https://events.openhatch.org/events/2>(https://events.openhatch.org/events/2) and Code of Conduct <https://openhatch.org/wiki/OpenHatch_event_code_of_conduct>(https://openhatch.org/wiki/OpenHatch_event_code_of_conduct) If this sounds interesting to you, and you're available on February 28 please email me back at dawn.walker(a)utoronto.ca <mailto:dawn.walker@utoronto.ca> and/or sign up on our Event Page <https://events.openhatch.org/events/2>(https://events.openhatch.org/events/2)<mailto:dawn.walker@utoronto.ca>, I'd love to answer any further questions you might have! Best, Dawn Walker MI Candidate, Faculty of Information University of Toronto

Wireless router: TP-Link Archer C7 $100
by D. Hugh Redelmeier 16 Feb '15

16 Feb '15

This week (unless supplies run out, which happens) NCIX has this wireless router for $99.49 with free shipping. This is one that Scott has and recommends for OpenWRT. He says that you should go for Version 2.0 and that the box will say if it is a Version 2.0 router. For that reason it may be better to buy it in one of their stores. It has been cheaper (briefly $70 and Future Shop and Best Buy) but not often recently. <http://www.ncix.com/detail/tp-link-archer-c7-ac1750-dual-1c-91525-1251.htm> <http://wiki.openwrt.org/toh/tp-link/tl-wdr7500>
