• In CentOS 4.3 Webmin 1.3000 bandwidth monitoring is eating disk space. How to delete those files?

  - by Silkograph

  I maintain Linux server being used for Mail, Squid and DNS service. Recently I observed that something was eating server disk space. But at last, today I caught the culprit which was consuming the disk by storing large number of files. On this server, Webmin 1.300 is installed. We use Squid proxy and Sarg to monitor Internet access. I always manually clear Sarg generated files under /var/www/html/squid for last few years. But I never realized that Webmin is also storing some kind of bandwidth log files in its' directory structure. I have noticed that under /etc/webmin/bandwidth/hours it has stored more thousands of files since year 2007 totaling about 17 GB. We have used 40 GB HDD for this server machine. My question is how can I delete those (/etc/webmin/bandwidth/hours) files safely?

• How can I retrieve data from a Western Digital Passport External Disk which is not getting recognized but getting shown as healthy in Device manager

  - by Rabimba Karanjai

  When I plug in this external harddisk It is not getting shown in the My Computer. But it gets shown perfectly well in the Device Manager When I go into the Computer Administrative panel and into the disk manager it asks me to initialize the disk Now when I try to initialize it, regardless of the method I try it shows me an error "Incorrect Function" As you can see windows tells me it is working properly. Is there anyway I can retrieve data from this?/access it? I have googled and it seems to be a frequent problem with WD drives. Anyone has any solutions on how I can get the data back?

• How is the 137GB limit counted in Virtual PC (two systems on one disk)?

  - by Nux

  I have a dual boot (Win7, XP) physical machine on my old computer which I want to virtualize and move to my new one. So I've uninstalled everything that I can and run shrink from RescueCD (used GParted). Now I have two about 80GiB partitions with a gap between them, so still this seem to be above the given limit. Still the resulting VHD (made with Disk2vhd) is much below the limit (about 110GiB) and both partitions are below the limit. So my question is - is it failing due to the limitations of disk size for VPC or is failing simply because it's a dual boot system. Or maybe it would work if I would move partitions to be close to each other (the gap between them is about 171GB and the whole physical disk is 1TB)?

• Laptop crashes when connecting to external harddisk

  - by Gnot

  I recently had a problem with my laptop. when I booted up the machine, I would get a SMART failure error message and when I pressed F1 to continue, it would take a very long time to boot and it would come back to the same error message again. Thinking that my hard disk was dying, I bought a new hard disk and installed on my laptop and so now my laptop is alright. However I need to recover data from that old hard disk, so I bought an external hard disk case and placed the old hard disk onto the case and connected to my laptop with USB. The first few times when I connected, I could see the files from the old hard disk and managed to copy some files over although it took extremely long to transfer. But now whenever I connect to the old hard disk, after a few minutes, my laptop will crash and re-boot. Do you think my old hard disk is dead beyond repair? Or you can offer some help here? Any assistance would be appreciated!

• How do I get a USB hard-disk adaper to work with a PCMCIA USB card?

  - by Carl

  I have a PCMCIA (Cardbus) 32bit USB 2.0 2-port card. If I plug my MP3 player in it works fine. I have a USB adapter for a hard disk drive. When I plug that into the PCMCIA USB slot the light on that hard disk flashed between red and green - it should stay green. "USB Mass Storage device" is added in the Device Manager, but no drive letter appears in My Computer. The installing device icon down by the clock never goes away. (Windows XP SP3.)

  - by amitahire

  I am new to Fedora, am still figure my way through it. I was going about tweaking it and preparing it to my needs, While installing through yum I dont have much other than the fact that I have to search for the packages. But when I open "Add/remove software" of Fedora. I am greeted with " No space left on the disk" and when I seek for more details it says " Disk Error :[errno 5] Input/output error" I did some research and I saw that it usually occurs during installation, but here I have successfully installed it. Can someone help me with it? Later on I even had notification of the same warning. And mind you I got loads of free space. Thanks for the help

• Why Virtualbox VDI doubles the space of the VM hard disk?

  - by logoff

  I have one Xubuntu 12.10 64 bit Virtualbox VM on a Windows 7 64 bit host. It has one dynamic allocated hard disk with VDI format with maximum capacity of 20GB. If I use a command df -h in the VM I get that 5.3GB are in use in th main partition. I have only 2 partitions, one for the ext4 hard disk and another with 512MB of swap. I have no snapshots. The VDI file of this VM has 10.7GB. It is normal this difference of space? It is caused because the VDI format?

• How to reduce Fedora's disk size in VMware player.

  - by user428862

  I'm new to Fedora 14, vmware player. After getting Fedora up and running in VMware player. The disk size was 2.7 GB. After three hours of working with it, the disk size has bloated to 4.3 GB. I havent added software to account for the near doubling in size. How do I reduce the size back to 2.7GB range or lower. Im new to Fedora and superuser controls. Im removing more software than adding software. Is this a VMWARE problem or Fedora problem?

• Laptop HDD not mounting.

  - by D3X

  I have a laptop with broken (shorted out) motherboard and a 640 GB HDD. I want to recover my data from the hard disk. Every time I connect the hard disk using an external casing, it is being detected in the disk management service but not visible in my computer, nor accessible through command prompt. The Hard Disk is functioning as I can feel the hard disk rotor working properly when connected using the casing. Also the LED on the hard disk is blinking, the data is there but i am unable to access the data. Someone please suggest me ways of using the hard-disk as a slave disk using casing.

• RAID 0 disk failure, how to recover the RAID?

  - by user7985

  Situation is this. A PC with 2 hard disks, in an RAID 0 Array. The electronics on one of the disks has failed. I can not find the same board for the disk (I've tried this, removed board from the OK disk, and the second, the damaged one, works fine). I've made an image with "dd" on linux on a new hard drive (same size, not same model) and now I get "Offline member" in the RAID config screen. Will I succeed to recover the data which is stored on the drives, any help, any experience with this kind of problem. And surly, I know it was stupid to put the disks in RAID 0 and store data on them :(

• How to save your Linux state (suspend to disk) periodically to recover from crashes?

  - by WoLpH

  One in a while my laptop crashes/dies because of a bad/empty battery, crappy wifi driver or whatever other reason. For a while I've wondered if it's possible to force Linux to periodically save the state (like vmware snapshots) to disk so you can restore from that with possibly slightly outdated work but at least with all of your apps open in the same state you've left them. I don't really see the point in having to boot everything from cratch constantly, although KDE saves your state on logout, that doesn't happen periodically (by default) either. It would make it much nicer to recover from your crashes if your ram was written to disk periodically. Anyone know if there's a system call to do this without also shutting down the machine? Even a manual button to save the entire state would be nice.

• Accessing host LVM partition from Windows XP through Virt.manager 0.8.5 / Qemu / KVM

  - by Nico de Smidt

  Hi, requested use case is having a Windows XP SP3 guest running in 64bit Ubuntu. (Linux pcs 2.6.35-22-server #35-Ubuntu SMP Sat Oct 16 22:02:33 UTC 2010 x86_64 GNU/Linux) I want this guest to access an LVM LV on the Ubuntu disk. I've setup the following LVM config: --- Logical volume --- LV Name /dev/storage/sdc1 VG Name storage LV UUID Zg5IMC-OlqB-prL5-fgg4-3A9A-OgKP-oZ0QkJ LV Write Access read/write LV Status available # open 0 LV Size 1.01 GiB Current LE 259 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 251:3 -- 1) I've setup a storage pool for /dev/storage 2) I've mkfs.vfat /dev/storage/sdc1 3) and made a virtual IDE disk in the virt-manager setup for the guest. Target device: IDE Disk 2 Source path: /dev/storage/sdc1 -- Now when running XP (guest) Windows sees a new disk in Disk Manager and want's to install a partition on it, since it believes the drive is empty. After formatting from within Windows I can put data on the new disk volume. -- Back in Ubuntu however I cannot access this this any more since it created a partition within an LVM Logical Volume. Running fdisk -l shows the following: root@pcs:/media# fdisk -l /dev/storage/sdc1 Disk /dev/storage/sdc1: 1086 MB, 1086324736 bytes 32 heads, 63 sectors/track, 1052 cylinders Units = cylinders of 2016 * 512 = 1032192 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x8d72e4f4 Device Boot Start End Blocks Id System /dev/storage/sdc1p1 1 1050 1058368+ c W95 FAT32 (LBA) -- which seems fine to me, but when trying to mount /dev/storage/sdc1p1 I get the following error: mount /dev/storage/sdc1p1 /media/xp mount: special device /dev/storage/sdc1p1 does not exist which makes sense since in lvdisplay sdc1p1 does not exist Main question: I want to mount the vfat partition in both Ubuntu and XP What am I missing here????? regards, and thanks for your consideration.

• format/build raid 5 with one 4k drive, three 512b

  - by skidawgz

  I have 4 WD 1TB drives which I want to 4x1TB Raid5. I am not sure what course of action to take next. How do I configure my 4th drive (sde) to align with the rest? Will this affect performance?

• I can't install Ubuntu on my Dell Inspiron 15R at all

  - by Kieran Rimmer

  I'm attempting to install Ubuntu 12.04LTS, 64 bit onto a Dell Inspiron 15R laptop. I've shrunk down one of the windows partitions and even used gparted to format the vacant space as ext4. However, the install disk simply does not present any options when it comes to the partitioning step. What I get is a non-responsive blank table As well as the above, I've changed the BIOS settings so that USB emulation is disabled (as per Can't install on Dell Inspiron 15R), and changed the SATA Operation setting to all three possible options. Anyway, the install CD will bring up the trial version of ubuntu, and if I open terminal and type sudo fdisk -l, I get this: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xb4fd9215 Device Boot Start End Blocks Id System /dev/sda1 63 80324 40131 de Dell Utility Partition 1 does not start on physical sector boundary. /dev/sda2 * 81920 29044735 14481408 7 HPFS/NTFS/exFAT /dev/sda3 29044736 1005142015 488048640 7 HPFS/NTFS/exFAT /dev/sda4 1005154920 1953520064 474182572+ 83 Linux Disk /dev/sdb: 32.0 GB, 32017047552 bytes 255 heads, 63 sectors/track, 3892 cylinders, total 62533296 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xb4fd923d Device Boot Start End Blocks Id System /dev/sdb1 2048 16775167 8386560 84 OS/2 hidden C: drive If I type 'sudo parted -l', I get: Model: ATA WDC WD10JPVT-75A (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 41.1MB 41.1MB primary fat16 diag 2 41.9MB 14.9GB 14.8GB primary ntfs boot 3 14.9GB 515GB 500GB primary ntfs 4 515GB 1000GB 486GB primary ext4 Model: ATA SAMSUNG SSD PM83 (scsi) Disk /dev/sdb: 32.0GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 8589MB 8588MB primary Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.

• Need help partitioning when reinstalling Ubuntu 14.04

  - by Chris M.

  I upgraded to 14.04 about a month ago on my HP Mini netbook (about 16 GB hard disk). A few days ago the system crashed (I don't know why but I was using internet at the time). When I restarted the computer, Ubuntu would not load. Instead, I got a message from the BIOS saying Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key I took this to mean that I needed to reinstall 14.04. When I try to reinstall Ubuntu from the USB stick, I choose "Erase disk and install Ubuntu" but then I get a message: Some of the partitions you created are too small. Please make the following partitions at least this large: / 3.3 GB If you do not go back to the partitioner and increase the size of these partitions, the installation may fail. At first I hit Continue to see if it would install anyway, and it gave the message: The attempt to mount a file system with type ext4 in SCSI1 (0,0,0), partition # 1 (sda) at / failed. You may resume partitioning from the partitioning menu. The second time I hit Go Back, and it took me to the following partitioning table: Device Type Mount Point Format Size Used System /dev/sda /dev/sda1 ext4 (checked) 3228 MB Unknown /dev/sda5 swap (not checked) 1063 MB Unknown + - Change New Partition Table... Revert Device for boot loader installation: /dev/sda ATA JM Loader 001 (4.3 GB) At this point I'm not sure what to do. I've never partitioned my hard drive before and I don't want to screw things up.

• How do I record video to a local disk in AIR?

  - by Jim OHalloran

  I'm trying to record a webcam's video and audio to a FLV file stored on the users local hard disk. I have a version of this code working which uses NetConnection and NetStream to stream the video over a network to a FMS (Red5) server, but I'd like to be able to store the video locally for low bandwidth/flaky network situations. I'm using FLex 3.2 and AIR 1.5, so I don't believe there should be any sandbox restrictions which prevent this from occurring. Things I've seen: FileStream - Allows reading.writing local files but no .attachCamera and .attachAudio methids for creating a FLV. flvrecorder - Produces screen grabs from the web cam and creates it's own flv file. Doesn't support Audio. License prohibits commercial use. SimpleFLVWriter.as - Similar to flvrecorder without the wierd license. Doesn't support audio. This stackoverflow post - Which demonstrates the playback of a video from local disk using a NetConnection/NetStream. Given that I have a version already which uses NetStream to stream to the server I thought the last was most promising and went ahead and put together this demo application. The code compiles and runs without errors, but I don't have a FLV file on disk which the stop button is clicked. - <mx:Script> <![CDATA[ private var _diskStream:NetStream; private var _diskConn:NetConnection; private var _camera:Camera; private var _mic:Microphone; public function cmdStart_Click():void { _camera = Camera.getCamera(); _camera.setQuality(144000, 85); _camera.setMode(320, 240, 15); _camera.setKeyFrameInterval(60); _mic = Microphone.getMicrophone(); videoDisplay.attachCamera(_camera); _diskConn = new NetConnection(); _diskConn.connect(null); _diskStream = new NetStream(_diskConn); _diskStream.client = this; _diskStream.attachCamera(_camera); _diskStream.attachAudio(_mic); _diskStream.publish("file://c:/test.flv", "record"); } public function cmdStop_Click() { _diskStream.close(); videoDisplay.close(); } ]]> </mx:Script> <mx:VideoDisplay x="10" y="10" width="320" height="240" id="videoDisplay" /> <mx:Button x="10" y="258" label="Start" click="cmdStart_Click()" id="cmdStart"/> <mx:Button x="73" y="258" label="Stop" id="cmdStop" click="cmdStop_Click()"/> </mx:WindowedApplication> It seems to me that there's either something wrong with the above code which is preventing it from working, or NetStream just can't be abused in this wany to record video. What I'd like to know is, a) What (if anything) is wrong with the code above? b) If NetStream doesn't support recording to disk, are there any other alternatives which capture Audio AND Video to a file on the users local hard disk? Thanks in advance!

• What's going on with my server? High load, lots of idle CPU time, low disk utilization

  - by Jonathan

  I run a web site and send a legitimate opt-in, daily email newsletter to subscribers. Both the web hosting and email sending are done by the same machine. I have about 100,000 subscribers who have opted in to my daily email newsletter. My PHP script did a pretty good job sending mail to all of them until fairly recently, but as the list has grown I can't keep up. When I run top, I have very high load--usually at least 6 or 7, sometimes as high as 15--even though I only have two CPUs. However, when I run sar, my CPU is idle an average of about 30% of the time. So, it seems I'm not CPU bound. When I run iostat, it seems as though I'm not disk bound because my %util for each device is very low (no more than 5%). Given that I don't seem to be CPU bound or disk bound, why is top reporting such high load? Additionally, since I don't seem to be CPU bound or disk bound, why is my email sending script not able to keep up? Here's what I see when running top: top - 11:33:28 up 74 days, 18:49, 2 users, load average: 7.65, 8.79, 8.28 Tasks: 168 total, 5 running, 162 sleeping, 0 stopped, 1 zombie Cpu(s): 38.9%us, 58.6%sy, 0.8%ni, 0.0%id, 0.7%wa, 0.2%hi, 0.8%si, 0.0%st Mem: 3083012k total, 2144436k used, 938576k free, 281136k buffers Swap: 2048248k total, 39164k used, 2009084k free, 1470412k cached Here's what I see when running iostat -mx: avg-cpu: %user %nice %system %iowait %steal %idle 34.80 1.20 55.24 0.37 0.00 8.38 Device: rrqm/s wrqm/s r/s w/s rMB/s wMB/s avgrq-sz avgqu-sz await svctm %util sda 0.19 71.70 1.59 29.45 0.02 0.07 5.90 0.55 17.82 1.16 3.59 sda1 0.00 0.00 0.00 0.00 0.00 0.00 7.10 0.00 13.80 13.72 0.00 sda2 0.05 50.45 1.13 24.57 0.01 0.29 24.25 0.35 13.43 1.15 2.97 sda3 0.05 10.17 0.20 2.33 0.01 0.05 43.75 0.05 20.96 2.45 0.62 sda4 0.00 0.00 0.00 0.00 0.00 0.00 2.00 0.00 70.50 70.50 0.00 sda5 0.07 0.22 0.03 0.07 0.00 0.00 32.84 0.08 856.19 8.03 0.08 sda6 0.02 5.45 0.03 0.72 0.00 0.02 67.55 0.02 26.72 5.26 0.39 sda7 0.00 1.56 0.00 0.42 0.00 0.01 38.04 0.00 8.88 5.84 0.24 sda8 0.01 3.84 0.20 1.35 0.00 0.02 28.55 0.05 31.90 4.08 0.63 Here's what I see when running sar: 09:40:02 AM CPU %user %nice %system %iowait %steal %idle 09:50:01 AM all 30.59 1.01 49.80 0.23 0.00 18.37 10:00:08 AM all 31.73 0.92 51.66 0.13 0.00 15.55 10:10:06 AM all 30.43 0.99 48.94 0.26 0.00 19.38 10:20:01 AM all 29.58 1.00 47.76 0.25 0.00 21.42 10:30:01 AM all 29.37 1.02 47.30 0.18 0.00 22.13 10:40:06 AM all 32.50 1.01 52.94 0.16 0.00 13.39 10:50:01 AM all 30.49 1.00 49.59 0.15 0.00 18.77 11:00:01 AM all 29.43 0.99 47.71 0.17 0.00 21.71 11:10:07 AM all 30.26 0.93 49.48 0.83 0.00 18.50 11:20:02 AM all 29.83 0.81 48.51 1.32 0.00 19.52 11:30:06 AM all 31.18 0.88 51.33 1.15 0.00 15.47 Average: all 26.21 1.15 42.62 0.48 0.00 29.54 Here are the top handful of processes listed at the particular time I happened to run top -c: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 8180 mysql 16 0 57448 19m 2948 S 26.6 0.7 4702:26 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/bristno.pid --skip-external-locking 26956 brristno 17 0 0 0 0 Z 8.0 0.0 0:00.24 [php] <defunct> 26958 brristno 17 0 94408 43m 37m R 5.0 1.4 0:00.15 /usr/bin/php /home/brristno/public_html/dbv.php 22852 nobody 16 0 9628 2900 1524 S 0.7 0.1 0:00.17 /usr/local/apache/bin/httpd -k start -DSSL 8591 brristno 34 19 96896 13m 6652 S 0.3 0.4 0:29.82 /usr/local/bin/php /home/brristno/bin/mailer.php 1qwqyb6 i0gbor 24469 nobody 16 0 9628 2880 1508 S 0.3 0.1 0:00.08 /usr/local/apache/bin/httpd -k start -DSSL 25495 nobody 15 0 9628 2876 1500 S 0.3 0.1 0:00.06 /usr/local/apache/bin/httpd -k start -DSSL 26149 nobody 15 0 9628 2864 1504 S 0.3 0.1 0:00.04 /usr/local/apache/bin/httpd -k start -DSSL

• Finding out why Dell Controler is Degraded

  - by Kyle Brandt

  I installed open manage on a couple of my PE 2950s for snmp monitoring of the RAID. All the checks seem to come back okay except for controllerState: [root@aMachine ~]# snmpwalk -v 2c -c bestNotToPostPasswords myMachine -m +StorageManagement-MIB controllerstate StorageManagement-MIB::controllerState.1 = INTEGER: degraded(6) Other checks seems to indicate the battery, LD, and physicals disks are all good unless I missing something. Can anyone tell if I am missing something or neglecting something import in my RAID monitoring/understanding? I get degraded for both these servers I have set up.

• Is it possible to mount a disk image, created with dd, to a directory on a mounted external usb hdd?

  - by Keeper Hood

  I have an image of my home (/dev/sda3) partition, which I've created using the "dd" command. dd if=/dev/sda3 of=/path/to/disk.img I've deleted the home partition via gparted in order to enlarge my /dev/root partition. Then I've recreated the /dev/sda3 partition which is smaller in size then the one I've backed up to the image. I was wondering since I have a 2TB external HDD, could it be possible to mount my backed up image on the external HDD and then copy the files into the /home directory. Since the external HDD would be already in a "mounted state", I'm unsure whether this is a good idea, mounting on a mounted device. I'm running Slackware 13.37 (64bit). used ext4 on all the partitions. resized the root partition with gparted live cd. I've tried mount -t ext4 /path/to/disk.img /mng/image -o loop It gave me an fs error (wrong fs type, bad option, bad superblock on dev/loop/0) Then i did dmesg | tail which outputs: EXT4-fs (loop0) : bad geometry: block count 29009610 exceeds size of defice (1679229 blocks) I have no idea what to do, I want to restore my /home data from the image I've backed up.

• How to migrate a running KVM (with full disk copy) to another node?

  - by klipz

  I'm doing tests on KVM, and I'd like to see if I can make a hot migration, I mean the virtual machine won't stop running during the migration (but a few seconds of freeze is ok). I use a small cluster for my test : kvm1, kvm2, and kvmnfs. kvm1 and kvm2 runs the virtual machines kvmnfs is a NFS server, and it's mounted on /KVM on both kvm1 and kvm2 To migrate a VM (only RAM in fact) from kvm1 to kvm2, I run the same kvm command on kvm2 (with -incoming tcp:0:4444) that on kvm1, then I use "migrate -d tcp:kvm2:4444" : It works great, since the VM file is common to both machines. Now, I wan't to make a full migration (RAM + disk) of a local VM file (no more NFS) of kvm1 to kvm2. I tried to create an empty file, with touch, on kvm2 and use the same kvm command line + the "-incoming ..."). Then on kvm1 I use "migrate -d tcp:kvm2:4444" : It copies everything, then... the VM fails (any I/O disk gives an I/O error) ! And my VM file on kvm2, the one I created with touch, as still a size of 0 bytes. What am I doing wrong ? What is the exact command to use on kvm2 ? And what is the command to launch, in the monitoring mode, on kvm1 ?
