  • spontaneous hard disk password

    - by sc
    I had an HP proliant server go down recently. All of the sudden the sas controller (e200i) would not see any of the physical disks. New disks were detected just fine. I thought it was odd that all 6 disks would go down at one time so sent them to a data recovery firm to find out what happened. I'm being told that, somehow, all of the disks were spontaneously password protected. These are Hitachi 2.5" drives and I guess this is something of a known issue. The company has worked for a while to try and recover them, with no luck. Has anyone had experience with this? Any recommendations for how to recover the drives or a company that might have the expertise to do so?

  • Server drives: 2.5" SCSI less reliable than 3.5" ?

    - by Bill
    Just had an HP 2.5" SAS 10k drive fail on a RAID5 array after about 2.5 years. It made me wonder if this was a fluke or an indication that 2.5" drives are less reliable than 3.5" SAS drives. I've had many 3.5" SAS drives running for many years without any issues (knock on wood). I would think that smaller drives would generate less heat and therefore be more reliable, but couldn't find any evidence of this. I realize all drives will eventually fail and that it's a crap shoot with any particular model, but was hoping someone could point out some related studies or comment on the SCSI drive sizes they've found to be most reliable in servers. Thanks.

  • Issue with broken disk on Solaris with raidctl - how to proceed

    - by weismat
    I have a SunFire T2000 server which has 2 mirrored disks pairs. The server required an exchange of the system battery. After swaping the battery first no disks were found. After booting from CD we managed to find the disks, but now one disk is broken and the raidctl reports a failed synchronisation. The boot process stops now when trying to mount the file systems. The power light of the broken drive is not even blinking. What is the best way to proceed now ? Fortunately I could live with loosing the data on the drive as it is backed up, but I would like to keep the rest of the data as it contains /etc and get the server booting again.

  • What happens to missed writes after a zpool clear?

    - by Kevin
    I am trying to understand ZFS' behaviour under a specific condition, but the documentation is not very explicit about this so I'm left guessing. Suppose we have a zpool with redundancy. Take the following sequence of events: A problem arises in the connection between device D and the server. This causes a large number of failures and ZFS therefore faults the device, putting the pool in degraded state. While the pool is in degraded state, the pool is mutated (data is written and/or changed.) The connectivity issue is physically repaired such that device D is reliable again. Knowing that most data on D is valid, and not wanting to stress the pool with a resilver needlessly, the admin instead runs zpool clear pool D. This is indicated by Oracle's documentation as the appropriate action where the fault was due to a transient problem that has been corrected. I've read that zpool clear only clears the error counter, and restores the device to online status. However, this is a bit troubling, because if that's all it does, it will leave the pool in an inconsistent state! This is because mutations in step 2 will not have been successfully written to D. Instead, D will reflect the state of the pool prior to the connectivity failure. This is of course not the normative state for a zpool and could lead to hard data loss upon failure of another device - however, the pool status will not reflect this issue! I would at least assume based on ZFS' robust integrity mechanisms that an attempt to read the mutated data from D would catch the mistakes and repair them. However, this raises two problems: Reads are not guaranteed to hit all mutations unless a scrub is done; and Once ZFS does hit the mutated data, it (I'm guessing) might fault the drive again because it would appear to ZFS to be corrupting data, since it doesn't remember the previous write failures. Theoretically, ZFS could circumvent this problem by keeping track of mutations that occur during a degraded state, and writing them back to D when it's cleared. For some reason I suspect that's not what happens, though. I'm hoping someone with intimate knowledge of ZFS can shed some light on this aspect.

  • How is it possible for SSD's drives to have such a good latency?

    - by tigrou
    First time i read some information about SSD's, i was surprised to learn they internally use NAND flash chips. This kind of memory is generally slow (low bandwidth) and have high latency while SSD's are just the opposite. But here is how it works : SSD drives increase their bandwidth by using several NAND flash chips in parallel. In other words, they do some data striping (aka RAID0) across several chips (done by the controller). What i don't understand is how SSD's drives have such a low latency, whereas they are using NAND chips? (or at least lot better than what a typical single NAND chip would do) EDIT: I think under-estimate NAND chip capabilities. USB drives, while powered by NAND's are mostly limited by USB protocol (which have a pretty high latency) and the USB controller. That explain their poor performance in some cases.

  • Installing Solaris 10 on sunT5220 - ZFS/UFS raid 10?

    - by Matthew
    I am in a bit of a time crunch, and need to get two T5220's built. We were very happy to see two boxes in our aged inventory which had 8 HDD's each, but didn't think to check if they were running hardware RAID or not. Turns out that they aren't. When we install, we are given the option to use UFS or ZFS, but when we select a place to install we're only given the option of installing on one single disk. Is it possible to create a software raid 10 across all of the disks and install the OS on that? Sorry if any lingo is wrong, I'm not really a Sun guy and our guru is out of town right now. Any help would be really appreciated! Note: Most of the guides I've found on google entail installing the OS on a single disk, and then creating a separate RAID 10 on other disks. We would actually like the OS to reside on the RAID 10. Hope that clarifies things.

  • How to figure out disks performance in Xen?

    - by cpt.Buggy
    So, I have a Dell R710 with PERC 6/i Integrated and 6 450Gb Seagate 15k SAS disks in RAID10, I have 30 Xen vps working on it. Now I need to deploy second server with same hardware for same tasks and I want to figure out maybe it's a good idea to use RAID5 instead of RAID10 because we have a lot of "free" memory on first server and not so much "free space". How do I find out disks performance on first server and find out could I move it to RAID5 without slowing down of whole system?

  • HP DL380 G5 Predictive failure of a new drive

    - by CharlieJ
    Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ

  • When using RAID10 + BBWC why is it better to separate PostgreSQL data files from OS and transaction logs than to keep them all on the same array?

    - by Vlad
    I've seen the advice everywhere (including here and here): keep your OS partition, DB data files and DB transaction logs on separate discs/arrays. The general recommendation is to use RAID1 for OS, RAID10 for data (or RAID5 if load is very read-biased) and RAID1 for transaction logs. However, considering that you will need at least 6 or 8 drives to build this setup, wouldn't a RAID10 over 6-8 drives with BBWC perform better? What if the drives are SSDs? I'm talking here about internal server drives, not SAN.

  • ZFS Configuration advice

    - by rbarrette
    I need some advice on configuring ZFS. Here is what I have: Physical Disks: 4x 3 TB 2x 2 TB 2x 1 TB What is the best configuration for my Vdevs and storage pool. I want to maximaze space but still maintain redundancy. Should I just get 2 more 3TB's and just create 2x 3-3TB raid2z storage pools? Create a 1x 4-3TB raidz2 vdev? Can I put redundancy at the pool level and create individual vdevs for each drive and then add 2x 1TB+2TB striped vdevs to keep all vdevs the same size. Keep in mind I do need to migrate data from the smaller drives and am planning on adding more 3tb drives later on. What do you think?

  • Is it possible to create a Mirror or Stripe volume for the boot partition in Windows 2008/R2?

    - by Georgios
    Hello, I have a server with two identical disks and I have installed Windows Server 2008 R2 on C, which is a 60GB volume on Disk 0. Using the disk manager, I have attempted to create both a Mirror and Stripe volume in Disk 1 but every time I get the same error "No extents found in the plex". This error occurs after Windows has converted both disks to Dynamic. The fact that the manager allows me to attempt to do this would point to the fact that this is possible. However I have been unable to find any solutions to this error. Any ideas on how to solve this? Thanks Georgios

  • Fake demostration software for command line

    - by Joe
    I'm looking for some software that would be useful for giving demonstrations. I regularly have to show the effects of scrips ect to classes while talking about their effects, and equaly regularly I have finger trouble and have to rewrite various commands - wasting class time and general energy. I'd like to be able to record a sequence of commands in advance, and then play them back at the speed of my choosing. So I might have a file that containes the commands: echo "hello world!" ls ls -l ls -l | sort I'd like to be able to play these commands back by typing similar ones in. So I'd have a blinking command prompt and if I typed 'echo "hxxx' the command prompt would read home$echo "hell and if I typed any other letters the terminal would fill up with the remainder of the command until I press enter, when it executes the command. The point is that even if I screw up the command when typing it, the command that I'd prepared in advance would be executed. My question is - does similar software exist for giving demonstrations? or even, is this an easy thing to script up...? EDIT - two quick things first of all I'm on osx - but it would be nice to get a general solution for other people who arrive here from google. and second a lot of the comments/answers are concentrating on, in effect, making it fast and easy to enter long commands by means of hotkeys and the like. Actually I'd like it to at least look like I'm typing live - that's why I put in the bit about the one-to-one keymapping, but I don't think I explained that quite as well as I could have...

  • Can I split one RAID1 partition in two?

    - by Prosys
    I have a linux box with CentOS 6.2 and a RAID1 (2x 2Tb) configuration: /dev/md1 -> / (10G) /dev/md2 -> /home (1.9T) I want to split the md2 in two different partitions, so I can get the following configuration: /dev/md1 -> / (10G) /dev/md2 -> /home (1T) /dev/md3 -> /example (900G) How can I achieve this? I already know that I can resize the partition, but that doesn't alter the real partition table (only the md device), so how can I do this?

  • RAID1: Which disk will be mirrored?

    - by tmelen
    How does a RAID1 system determine which disk to use as the source and which disk to use as the destination when mirroring? Assume for instance the following scenario: A RAID1 array is created with two disks A and B. A is replaced by disk C, which is added to the array. Files are beeing modified as time goes by. Now B is removed and A is reinserted. Will the RAID1 system realize that A and C are out of sync? And that C is more up-to-date than A? And if not, is there a safe way to avoid the mirroring process to start immediately when disk A is inserted?

  • How does a Promise FastTrak 133 interleave a striped array?

    - by Jemenake
    I co-worker had two drives configured as a stripe on a motherboard with an on-board Promise FastTrak 133. The motherboard failed, and we've been unable to find any others with an on-board Promise controller which can recognize the array. With Linux or some disk editors, I can see data on both drives... and I want to see if I can combine the data from both drives onto a single, larger drive. But I need to know how that information is interleaved on the drives. I've tried dmraid on Linux, but that doesn't recognize the drives as an array. I guess I could just try combining alternating blocks from the drives, starting with a block size of 256B and keep doubling until I get a result that looks intact. But I'd like to avoid that if someone already knows how Promise controllers spread the data over a striped array.

  • Software disables itself when the PC is accessed via RDP

    - by blckgrffn
    We have a large, specialty printer that has vendor specific software that enables its use outside of it showing up simply as a printer in the Windows Control Panel. This software recognizes when we RDP into the machine and "disconnects" the PC from the printer within its proprietary control panel. All is well when an application like TeamViewer is used to access the machine. Ostensibly, the application is helping us be safe by "enforcing" that the machine used for the printer is a walk up workstation, or so the support folks informed me. If TeamViewer etc, fixes the issue, then what is the problem? We have many headless workstations in our warehouse attached to a variety of specialty machines, all used via RDP. We want/need to keep access to the machines the same for the sanity of our production staff. The meat of the question - how, specifically, might a machine know that it is being accessed via RDP (terminal services management???) and how might this be defeated without altering an application or driver. Of note, the system being used is a Windows 7 Pro machine hooked to the printer via USB. Thanks! Nat edit Is there any combination of /admin switches, etc. that will possibly fix this? Simply putting /admin did not.

  • Have two partitions in RAID1

    - by mateikav
    The answers are unclear wherever I look. I have two 2TB drives for a RAID1 and I want to mirror them while having two partitions on the drives. One partition will be 100GB and contain programs, the other partition will be 1.8TB and contain personal files. Some may ask why? The answer is that my programs are currently on another older drive and I want to save time and pain uninstalling and re-installing critical programs while merely copying them to the new drives via Shadowcopy. When I create the RAID1, will both partitions be mirrored? Is this possible? I am sorry if I am being confusing or unclear.

  • Rebuild mdadm RAID5 array with fewer disks

    - by drjeep
    I have a 4 disk RAID5 array, one of which is starting to fail according to smartd. However, since I'm using less than half the space on /dev/md0, I'd like to rebuild the array without the failing disk. The closest scenario I've been able to find online has been this post, however it contains bits that don't apply to me (LVM volumes) and also doesn't explain how I go about resizing the partition after I'm done. Please note I have backups of important data, but I'd like to avoid rebuilding the array from scratch if possible.

  • Java update/install via group policy

    - by Maximus
    I trying to deploy the latest Java RE version via GP, Java 7 update 9. I want to update computers that are currently running an older version of Java, a mixture of 7.6 and 7.7, some computers are running versions as old as 6.31. Some are running a mixture of both. I would also like this GP to install Java if it's not installed. Previously I used push out Java updates to users machines as Java didn't remove the old version. So when it was done the user would restart their browser or pc to start using the latest version. Not the best way to manage it as it leaves the old version installed but it worked. I've created group policies before for printer deployment, log on drive mapping scripts, but never software deployment. I've extracted the Java MSI and created a transform file to suppress reboot etc using orca. As described on this site http://ivan.dretvic.com/2011/06/how-to-package-and-deploy-java-jre-1-6-0_26-via-group-policy/. I have also tried saving the edited MSI directly and that didn't work either. But it just won't deploy. I have tried to enable logging as suggested on this site http://openofficetechnology.com/node/32, GPO logging via UserEnvDebugLevel, Software deployment logging via AppmgmtDebugLevel and MSI logging, but there is no log C:\Windows\Debug\UserMode\userenv.log being created. The windows event viewer has the following errors: Error 24/10/2012 11:44:04 AM - "Failed to apply changes to software installation settings. Software changes could not be applied. A previous log entry with details should exist. The error was : %%1612" Information 24/10/2012 11:44:04 AM - "The removal of the assignment of application Java 7 Update 9 - FB Java Transform from policy JavaDeploy succeeded." Error 24/10/2012 11:44:04 AM - "The install of application Java 7 Update 9 - FB Java Transform from policy JavaDeploy failed.

  • UV texture mapping with perspective correct interpolation

    - by Twodordan
    I am working on a software rasterizer for educational purposes and I am having issues with the texturing. The problem is, only one face of the cube gets correctly textured. The rest are stretched edges: You can see the running program online here. I have used cartesian coordinates, and all I do is interpolate the uv values along the scanlines. The general formula I use for interpolating the uv coordinates is pretty much the one I use for the z-buffering interpolation and looks like this (in this case for horizontal scanlines): u_Slope = (right.u - left.u) / (triangleRight_x - triangleLeft_x); v_Slope = (right.v - left.v) / (triangleRight_x - triangleLeft_x); //[...] new_u = left.u + ((currentX_onScanLine - triangleLeft_x) * u_Slope); new_v = left.v + ((currentX_onScanLine - triangleLeft_x) * v_Slope); Then, when I add each point to the pixel buffer, I restore z and uv: z = (1/z); uv.u = Math.round(uv.u * z *100);//*100 because my texture is 100x100px uv.v = Math.round(uv.v * z *100); Then I turn the u v indexes into one index in order to fetch the correct pixel from the image data (which is a 1 dimensional px array): var index = texture.width * uv.u + uv.v; //and the rest is unimportant imagedata[index].RGBA bla bla The interpolation formula is correct considering the consistency of the texture (including the straight stripes). However, I seem to get quite a lot of 0 values for either u or v. Which is probably why I only get one face right. Furthermore, why is the texture flipped horizontally? (the "1" is flipped) I must get some sleep now, but before I get into further dissecting of every single value to see what goes wrong, Can someone more experienced guess why might this be happening, just by looking at the cube? "I have no idea what I'm doing" (it's my first time implementing a rasterizer). Did I miss an important stage? Thanks for any insight. PS: My UV values are as follows: { u:0, v:0 }, { u:0, v:0.5 }, { u:0.5, v:0.5 }, { u:0.5, v:0 }, { u:0, v:0 }, { u:0, v:0.5 }, { u:0.5, v:0.5 }, { u:0.5, v:0 }

  • C# Domain-Driven Design Sample Released

    - by Artur Trosin
    In the post I want to declare that NDDD Sample application(s) is released and share the work with you. You can access it here: http://code.google.com/p/ndddsample. NDDDSample from functionality perspective matches DDDSample 1.1.0 which is based Java and on joint effort by Eric Evans' company Domain Language and the Swedish software consulting company Citerus. But because NDDDSample is based on .NET technologies those two implementations could not be matched directly. However concepts, practices, values, patterns, especially DDD, are cross-language and cross-platform :). Implementation of .NET version of the application was an interesting journey because now as .NET developer I better understand the differences positive and negative between these two platforms. Even there are those differences they can be overtaken, in many cases it was not so hard to match a java libs\framework with .NET during the implementation. Here is a list of technology stack: 1. .net 3.5 - framework 2. VS.NET 2008 - IDE 3. ASP.NET MVC2.0 - for administration and tracking UI 4. WCF - communication mechanism 5. NHibernate - ORM 6. Rhino Commons - Nhibernate session management, base classes for in memory unit tests 7. SqlLite - database 8. Windsor - inversion of control container 9. Windsor WCF facility - for better integration with NHibernate 10. MvcContrib - and in particular its Castle WindsorControllerFactory in order to enable IoC for controllers 11. WPF - for incident logging application 12. Moq - mocking lib used for unit tests 13. NUnit - unit testing framework 14. Log4net - logging framework 15. Cloud based on Azure SDK These are not the latest technologies, tools and libs for the moment but if there are someone thinks that it would be useful to migrate the sample to latest current technologies and versions please comment. Cloud version of the application is based on Azure emulated environment provided by the SDK, so it hasn't been tested on ‘real' Azure scenario (we just do not have access to it). Thanks to participants, Eugen Gorgan who was involved directly in development, Ruslan Rusu and Victor Lungu spend their free time to discuss .NET specific decisions, Eugen Navitaniuc helped with Java related questions. Also, big thank to Cornel Cretu, he designed a nice logo and helped with some browser incompatibility issues. Any review and feedback are welcome! Thank you, Artur Trosin

  • GNU/Linux interactive table content GUI editor?

    - by sdaau
    I often find myself in the need to gather data (say from the internet), into a table, for comparison reasons. I usually need the final table output in HTML or MediaWiki mostly, but often times also Latex. My biggest problem is that I often forget the correct table syntax for these markup languages, as well as what needs to be properly escaped in the inline data, for the table to render correctly. So, I often wish there was a GUI application, which provides a tabular framework - which I could stick "Always on Top" as a desktop window, and I could paste content into specific cells - before finally exporting the table as a code in the correct language. One application that partially allows this is Open/LibreOffice calc: The good thing here is that: I can drag and drop browser content into a specifically targeted table cell (here B2) "Rich" text / HTML code gets pasted For long content, the cell (column) width stays put as it originally was The bad thing is, that: when the cell height (due to content size) becomes larger than the calc window, it becomes nearly impossible to scroll calc contents up and down (at least with the mousewheel), as the view gets reset to top-right corner of the selected cell calc shows an "endless"/unlimited field of cells, so not exactly a "table" - which I find visually very confusing (and cognitively taxing) Can only export table to HTML What I would need is an application that: Allows for a limited size table, but with quick adding of rows and columns (e.g. via corresponding + buttons) Allows for quick setup of row and column height and width (as well as table size) Stays put at those sizes, regardless of size of content pasted in; if cell content overflows, cell scrollbars are shown (cell content could be possibly re-edited in a separate/new window); if table overflows over window size, window scrollbars are shown Exports table in multiple formats (I'd need both HTML and mediawiki), properly escaping cell content for each (possibility to strip HTML tags from content pasted in cells, to get plain text, is a plus) Targeting a specific cell in the table for the content paste operation is a must - it doesn't have to be drag'n'drop though, a right click over a cell with "Paste content" is enough. I'd also want the ability to click in a specific cell and type in (plain text) content immediately. So, my question is: is there an application out there that already does something like this? The reason I'm asking is that - as the screenshots show - for instance Libre/OpenOffice allows it, but only somewhat (as using it for that purpose is tedious). I know there exist some GUI editors for Linux (both for UI like guile or HTML like amaya); but I don't know them enough to pinpoint if any of them would offer this kind of functionality (and at least in my searches, that kind of functionality, if present in diverse software, seems not to be advertised). Note I'm not interested in styling an HTML table, which is why I haven't used "table designer" in the title, but "table editor" (in lack of better terms) - I'm interested in (quickly) adjusting row/column size of the table, and populating it with pasted data (which is possibly HTML) in a GUI; and finally exporting such a table as self-contained HTML (or other) code.
