What does the "Maximum Frequency" number mean in the Windows Resource Monitor?

- by nhinkle

In the Windows Resource Monitor's CPU tab, there is a status box and graph for the "Maximum Frequency", right next to the "CPU Usage" values. What does this mean? The value is sometimes over 100% on my system... what could that imply? By looking at CPU-z's real-time report of the processor's clock speed, it seems to be loosely related to what frequency the CPU is running at, which would imply that it means "percent of maximum possible frequency the CPU is running at"; this would be of relevance on systems with SpeedStep and/or TurboBoost technology (or similar). Furthermore, setting the system to "power saving mode" lowers the "maximum frequency" value to around 60%, while setting it to "high performance" mode sets it to around 110%. However, the percentage does not seem to exactly correlate to the CPU speed being shown. What value is this actually representing then?

Degraded RAID5 and no md superblock on one of remaining drive

- by ark1214

This is actually on a QNAP TS-509 NAS. The RAID is basically a Linux RAID. The NAS was configured with RAID 5 with 5 drives (/md0 with /dev/sd[abcde]3). At some point, /dev/sde failed and drive was replaced. While rebuilding (and not completed), the NAS rebooted itself and /dev/sdc dropped out of the array. Now the array can't start because essentially 2 drives have dropped out. I disconnected /dev/sde and hoped that /md0 can resume in degraded mode, but no luck.. Further investigation shows that /dev/sdc3 has no md superblock. The data should be good since the array was unable to assemble after /dev/sdc dropped off. All the searches I done showed how to reassemble the array assuming 1 bad drive. But I think I just need to restore the superblock on /dev/sdc3 and that should bring the array up to a degraded mode which will allow me to backup data and then proceed with rebuilding with adding /dev/sde. Any help would be greatly appreciated. mdstat does not show /dev/md0 # cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] md5 : active raid1 sdd2[2](S) sdc2[3](S) sdb2[1] sda2[0] 530048 blocks [2/2] [UU] md13 : active raid1 sdd4[3] sdc4[2] sdb4[1] sda4[0] 458880 blocks [5/4] [UUUU_] bitmap: 40/57 pages [160KB], 4KB chunk md9 : active raid1 sdd1[3] sdc1[2] sdb1[1] sda1[0] 530048 blocks [5/4] [UUUU_] bitmap: 33/65 pages [132KB], 4KB chunk mdadm show /dev/md0 is still there # mdadm --examine --scan ARRAY /dev/md9 level=raid1 num-devices=5 UUID=271bf0f7:faf1f2c2:967631a4:3c0fa888 ARRAY /dev/md5 level=raid1 num-devices=2 UUID=0d75de26:0759d153:5524b8ea:86a3ee0d spares=2 ARRAY /dev/md0 level=raid5 num-devices=5 UUID=ce3e369b:4ff9ddd2:3639798a:e3889841 ARRAY /dev/md13 level=raid1 num-devices=5 UUID=7384c159:ea48a152:a1cdc8f2:c8d79a9c With /dev/sde removed, here is the mdadm examine output showing sdc3 has no md superblock # mdadm --examine /dev/sda3 /dev/sda3: Magic : a92b4efc Version : 00.90.00 UUID : ce3e369b:4ff9ddd2:3639798a:e3889841 Creation Time : Sat Dec 8 15:01:19 2012 Raid Level : raid5 Used Dev Size : 1463569600 (1395.77 GiB 1498.70 GB) Array Size : 5854278400 (5583.08 GiB 5994.78 GB) Raid Devices : 5 Total Devices : 4 Preferred Minor : 0 Update Time : Sat Dec 8 15:06:17 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 1 Spare Devices : 0 Checksum : d9e9ff0e - correct Events : 0.394 Layout : left-symmetric Chunk Size : 64K Number Major Minor RaidDevice State this 0 8 3 0 active sync /dev/sda3 0 0 8 3 0 active sync /dev/sda3 1 1 8 19 1 active sync /dev/sdb3 2 2 8 35 2 active sync /dev/sdc3 3 3 8 51 3 active sync /dev/sdd3 4 4 0 0 4 faulty removed [~] # mdadm --examine /dev/sdb3 /dev/sdb3: Magic : a92b4efc Version : 00.90.00 UUID : ce3e369b:4ff9ddd2:3639798a:e3889841 Creation Time : Sat Dec 8 15:01:19 2012 Raid Level : raid5 Used Dev Size : 1463569600 (1395.77 GiB 1498.70 GB) Array Size : 5854278400 (5583.08 GiB 5994.78 GB) Raid Devices : 5 Total Devices : 4 Preferred Minor : 0 Update Time : Sat Dec 8 15:06:17 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 1 Spare Devices : 0 Checksum : d9e9ff20 - correct Events : 0.394 Layout : left-symmetric Chunk Size : 64K Number Major Minor RaidDevice State this 1 8 19 1 active sync /dev/sdb3 0 0 8 3 0 active sync /dev/sda3 1 1 8 19 1 active sync /dev/sdb3 2 2 8 35 2 active sync /dev/sdc3 3 3 8 51 3 active sync /dev/sdd3 4 4 0 0 4 faulty removed [~] # mdadm --examine /dev/sdc3 mdadm: No md superblock detected on /dev/sdc3.

Feedback on Using ZFS and FreeBSD

- by ToiletOverflow

I need to create a server that will be used solely for backing up files. The server will have 2TB of storage to begin with but I may want to add additional storage later on. As such, I am currently considering using FreeBSD + ZFS as the OS and file system. Is ZFS a reliable, trusted file system? Should I use it in this scenario? I have read that ZFS should be used with OpenSolaris over FreeBSD as OpenSolaris is usually ahead of the curve with ZFS as far as version updates and stability. However, I am not interested in using OpenSolaris for this project. An alternative option that I am considering is to stick with ext3 and create multiple volumes if need be, because I know that I will not need a single, continuous volume larger than 2TB. Thanks in advance for your feedback.

Created User in Linux (Ubuntu) Without Creating a Home Directory - Causing Problems

- by nicorellius

This may be a rookie mistake, but I created a user (new user) in Linux on a Ubuntu system and didn't actually create the home directory for this user. Now, when I log in, it says there are problems... If I delete the path home/<new user> and try to log in the system tells me I can use root as home directory but I will likely experience problems, and then it won't let me log in. What is the best way to create this directory with the appropriate permissions? Should I just create another user and delete this one? I need some help...

WD My Passport detected but not assigned a drive letter

- by abel

I have a WD My Passport external drive which used to work fine on my Win7 x64 box until recently. Since the past few days, windows would not detect my external drive. However, Storage under disk management lists my external drive(which means windows can see my drive) but without a drive letter. I am not able to assign a drive letter(the option is grayed out). I installed EASUS Partition Manager which allows me to assign a drive letter, but fails to do so when I apply to save changes. What do i do to assign a drive letter to the drive or make windows to detect it as of old? The external drive works well on Win7 x32(dual boot, same system) and win7 x64 on another box. Update: cant comment from Opera Mini 6 @zeke the drive works absolutely fine on other Win7 boxes and on the dual boot win7 on the same system.

Windows 7 file-based backup service

- by Ben Voigt

I'm looking for a good replacement for Lazy Mirror, since it doesn't support Windows 7 well. Pros: One of the things I really loved about Lazy Mirror is that it always maintains a "full" backup, but does so by only copying modified files. As each file was copied, the old version got archived (moved to an out-of-the-way location). So after mirroring ran, there'd be a complete copy of the file system, which could even be booted if necessary. At the same time, extra space on the backup media was used to store as many older versions of files as possible, without wasting space storing multiple copies of the same version. It seems that with Windows 7 backup, there'd be wasted space storing the same data in both the system image and file backup. It was completely file-based, but also aware of the registry (it had a feature to dump the live registry to hive files in the correct format). The backups were normal NTFS filesystems, no special tool was needed to read them. It automatically cleaned out the oldest previous versions when space ran out (unlike Windows 7 backup which apparently simply starts failing the the backup media fills.) It copied all file attributes including security. Cons: It doesn't deal well with junction points, symbolic links, and hard links. It didn't run as a service without lots of help from firesrv or srvany, and then you couldn't interact with the GUI. Running as a service was necessary to be able to mirror protected OS files. It didn't have open file handling, except for registry hives. I guess that the file-by-file archive and replacement could leave mismatched sets of files, if the mirror was interrupted. This would be the advantage of incremental backup techniques that require old full backup + all intermediate incremental backups to restore. But I don't see this as presenting much of a problem, you'd really only have a boot failure if you had a mixture of pre- and post-service pack files, and I can run a full image backup using another tool before applying a service pack. Does anyone know of a tool that does both full-system backup and storage of old versions of files like Lazy Mirror did (without storing the same data multiple times), and also can run as a service in Windows 7? Free is best of course, but a reasonably priced paid program (e.g. It would be absolutely awesome if it also triggered a backup/mirror pass when a particular external drive was plugged in and generated popup warnings if backups hadn't been run recently)

How do i find out what's preventing delete requests from working in iis7.5 and iis8?

- by Simon

Our site has an MVC Rest API. Recently, both the live servers and my development machine stopped accepting DELETE requests, instead returning a 501 Not Implemented response. On my development machine, which is Windows 7 running IIS7.5, the solution was to add these lines to our Web.config, under system.webServer / handlers: <remove name="ExtensionlessUrlHandler-Integrated-4.0" /> ... <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" /> However, this didn't work on any of our live servers; not on Sever 2008 + IIS7.5 and not on Server 2012 + IIS8. There are no verbs set up in Request Filtering, and WebDAV is not installed on any of our live servers. The error page gives no further information, and nothing gets recorded in the logs. How do I find out what's preventing DELETE requests from working in iis7.5 and iis8?

postgres memory allocation tuning 2

- by pstanton

i've got a Ubuntu Linux system with 12Gb memory most of which (at least 10Gb) can be allocated solely to postgres. the system also has a 6 disk 15k SCSI RAID 10 setup. The process i'm trying to optimise is twofold. firstly a single threaded, single connection will do many inserts into 2-4 tables linked by foreign key. secondly many different complex queries are run against the resulting data, using group by extensively. this part especially needs to be optimised. i have four of these processes running at once in order to make use of the quad core CPU, therefore there will generally be no more than 5 concurrent connections (1 spare for admin tasks). what configuration changes to the default Postgres config would you recommend? I'm looking for the optimum values for things like work_mem, shared_buffers etc. relevant doco thanks!

My saved drafts become unread email in Windows Live Mail and Gmail IMAP

- by Valamas

I have setup windows live mail with my gmail account in IMAP mode. When I draft an email and save it. It saves in the drafts automatically. Within a minute, my WLM sound alerts new mail and shows mail icon in the system tray. However, this is for the draft I have saved which appears unread. To make the mail notification icon go away in the system tray, I go off and mark the draft as read. This repetition is tedious and distracting. How can I avoid this annoyance? thanks

Restoring the exact state of a linux install to a different laptop with different sized drives and other hardware

- by user259774

I have an IBM running a Manjaro install that has already been used and settled into, with packages installed, browser profiles, etc, etc. The drive is 60gb, and it has a swap partition and an ext4 root partition. I need to move this profile to a Toshiba computer with a 320gb drive. How should I go about this? My inclination would be to shut down the toshiba, boot a live linux system, dd the whole 60gb drive to a file, boot the toshiba to a live system, then dd the file to its 320gb drive. Would this work? I know that it wouldn't with windows, but I believe this is an artificially imposed limitation from Microsoft. Is this correct, or is Linux similarly limited? If not, how could I go about this? Would clonezilla work, or would the hardware disparities prevent it from working?

Tips for teaching Linux to beginners?

- by chiborg

I will teach Linux to people of the ages 20-75 with no prior Linux knowledge. I want to teach some basic concepts (what's an OS, what's a file system) and some practical knowlede: How to install it, network configuration, set up email client, installing software with a packet manager, etc. I have held a system administrators course in the past, but was under the impression that my method of teaching was not adequate. I've explained what I was about to show, showed students on the projector, told them to repeat it on their computers and summarized what they should have learned. They could ask questions all the time. But I fear they remembered only one-third of the knowledge I taught them. I have two questions here: Are there better methods to teach this particular subject in a classroom equipped with computers? Are there some tricks that "slow me down" when I teach stuff that I know inside-out?

Mother Board Question

- by user33931

1st, I am software guy. I do not do hardware. So I know to you hardware geeks, this is a dumb question. I just inherited a box with a ASUS P5GZ-MX mother board. I have attempted to install two nVidia PCI video cards. I put a 750w power supply in the system to be sure I have enough power. With no extra video cards, the 3.3 v shows normal. When I put one card in, the 3.3 goes to 3.5-3.6 and flashes red (over voltage) about 30% of the time. When I put the 2nd card in, it goes to 3.73 v and stays red all the time. Any Ideas why the voltage goes up when I add cards instead of going down? More Importantly, is this dangerous to the system?

Postfix tutorial inconsistency

- by Desmond Hume

I'm following this tutorial to setup a Postfix/Dovecot mail server with Postfix Admin as a web front end. As regards directory structure for virtual mail users, the author of the tutorial writes: Virtual mail users are those that do not exist as Unix system users. They thus don't use the standard Unix methods of authentication or mail delivery and don't have home directories. That is how we are managing things here: mail users are defined in the database created by Postfix Admin rather than existing as system users. Mail will be kept in subfolders per domain and account under /var/vmail - e.g. [email protected] will have a mail directory of /var/vmail/example.com/me. But when he gives instructions about configuring Postfix Admin, he suggests this to be contained by Postfix Admin's config.inc.php: // Mailboxes // If you want to store the mailboxes per domain set this to 'YES'. // Examples: // YES: /usr/local/virtual/domain.tld/[email protected] // NO: /usr/local/virtual/[email protected] $CONF['domain_path'] = 'NO'; Is there an inconsistency?

ITIL Incident Classification - Fault vs SR vs Technical Incident

- by ExceptionLimeCat

I am new to ITIL and Incident classifcations and I am trying learn more about them and understand how they could integrate in our organization. I have found it difficult to find a clear definition of Fault vs. Service Request vs. Technical incidents. I am basing my definitions on this article: http://www.itsmsolutions.com/newsletters/DITYvol6iss27.htm As I understand it: Service Request - Service provided by IT as part of regular administration of a system. Fault - An unexpected error in a system. Technical Incident - An interruption or potential interruption in IT service due to an expected incident caused by some IT policy.

How best to backup 6x Win2k3 Servers

- by saille

We have a external HP LTO3 tape drive. It needs to backup 6 Windows 2003 machines every night. Servers are HP DL380 G3 and the tape drive is attached locally to one of them via SCSI. On a budget of $0, and a goal of keeping-it-simple, what is going to be the best way to backup these machines? What software to use? NT Backup? Or does HP have something better for free? We don't need image backups - file system + system state will be adequate. Do we need to copy the files to be backed up onto the machine with the tape drive attached? Edit: Let me ask a more focussed question: Would you use NT Backup or something else? No soap boxing please, we've after some quick advice from someone who's used a similar setup.

Making Sure Which Partition to Choose with Linux Dual Boot?

- by user128360

In the Linux Mint 12 LXDE the partitions are listed as nsd 1, 2, 3, 4, though I have a Windows 8 CP installation on one of the two partitions on the single hard drive. The space usage is differing in both system calculations, though still relateable. Where the partition is at around 20 GB usage in Windows 8 it will be at around 24 GB in the Linux installation menu. I am just wondering is there a certain way to choose the right partition? Also in the drop down menu regarding the boot loader, there are multiple options, which one would be the one to be chosen in this case? What about the system-reserve partition of Windows 7 (the one I am trying to overwrite)? What is happening with that?

Hi, I have following partitions on a 1 TB disk. 14 GB UNKNOWN recovery partition 100MB NTFS System Reserved partition for Windows 7 448GB NTFS Windows 7 system partition 468GB NTFS Data partition for windows 7 Now because of the problems mentioned in my other question here I got a brand new windows 7 cd and want to install it from scratch after deleting all the extra partitions. But windows 7 installation doesn't give me such options. It refuses to touch the 14GB Recovery and 100 MB (reserved by previous windows 7) partition. Any ideas ? Note: Because of it is a dynamic disks most of the freely available tools refuse to delete the partitions on the disk. regards.

HD movies stutter.

- by Absolute0

I just put together a new system build in the hopes that all of my daily tasks would run smoothly and without any hiccups. Unfortunately I am still seeing some sound and sometimes video stuttering when playing HD movies in VLC (no problems with xvid/divx files). My setup is as follows: Intel core i5 750 quad core 2.66mhz 4GB ram asus p55 motherboard radeon hd 5570 video card 650gb 7200rpm western digital sata HDD 23" Nec ea23wmi monitor Operating System: Windows 7 What might be the main bottleneck that needs upgrading to fix my delays? Seems like the hard drive might be the problem but anything faster than 7200rpm is beyond my budget for a decent hard drive. Could it be anything else?

Is it possible to install Windows 8 on the SanDisk ReadyCache 32GB SSD drive?

I bought the SanDisk ReadyCache 32GB SSD drive this week. I didn't know about the caching stuff and thought that I would be able to install Windows 8 on it. Now I'm using it as a cache drive with the ExpressCache software. But I wonder if it is possible to use this SSD as a primary system drive with an operating system installed on it. I've tried to format the disk via Windows Disc Manager Tool, but the format option is disabled. Only delete and information options are allowed. Can you help me with this?

baffling stat pauses - (reiserfs)

- by Twirrim

I've got a SuSE server with reiserfs formatted partitions, all on a RAID1 mirror. I'm noticing odd spikes in iowait, but generally all seems okay. iostat claims not even 3% iowait in general: avg-cpu: %user %nice %system %iowait %steal %idle 6.53 0.03 1.45 2.92 0.00 89.07 After tracking down some odd behaviour when ls'ing, it appears "stat" (ls is aliased to include color which does a stat process on each file) randomly takes 5 seconds on a file in the directory. ReiserFS does a file system sync every 5 seconds, but that's interval between not length of time taken to sync. Out of curiosity I did remount using noatime to see if that would help though as it would reduce sync's workload, but no joy. Anyone got any thoughts what might be causing this pause? Disks appear healthy, RAID controller believes the RAID is healthy, and io stats show the disks aren't working very hard at all.

g++ in Knoppix 6 LiveCD

- by HazyBlueDot

To avoid the inevitable, let me put this in context. I am instructing an Intro to Unix course this semester and the students are using Knoppix 6.4.3 off the LiveCD. They are not required to install the system to their hard drive, and I would like to not require them to, however they do have use of a USB flash drive. This version of Knoppix seems to include gcc, but NOT g++. The course curriculum requires compiling C++ programs. I know I can run: sudo apt-get update sudo apt-get install build-essential to install (among other things) g++, but of course this only makes sense on a system installed to a hard drive. So my question is, can I write a script that calls gcc with appropriate options and flags to compile a C++ program that students could use in place of g++?
