CentOS 5 :: 5.3 Hangs While Remotely Copying Data Onto Server?
Jan 25, 2010
Problem : centos 5.3 hangs while remotely copying data onto this server.
I have A centos 5.3 x86 Version installed on Xeon Quad core , running on 8 GB DDR2 RAM, RAID 1 confgured on SATA drives. this was old installation copy and It has many more things running on it.Therfore, I can't just reinstall it.
I have setup SAMBA PDC + ldap on it. I encounter that system hangs when I copy data into this server from LAN computers.
My troubleshooting steps :
1. I have checked for network issue , My network works fine when I transfer data between other LAN compuers.
2. Even I have tried confguring seprate LAN....
3. I thought their might be some problem with my SAMBA configuration, therefore I did data transfer from sftp .
I built a centralized storage system a year ago (Aug. 2010) and for the past 10 months it has preformed flawlessly. About two months ago (July 2011) I began having problems writing to my centralized storage. The copies (cp -rpv) fail whether they are nfs or samba mounted disks to my centralized storage.
Attempting to copy either frame sequence (.dpx, .tiffs, .targas) or .MOV files now lock up my system and knock my storage offline.
The error that continues to echo back when this happens is :
I have not made any changes or updates to my storage configuration since building it last August 2010. I have reached out to Areca, and they found nothing wrong with the Raid Controller or my Raid settings.
I tried to troubleshoot all the basics - swapped out cables, replaced the WD storage disks, changed switches still the problem persists.
If anyone else has experienced this issue please let me know what you did to fix it. I can also post any error logs or message logs if that would be of assistance.
I'm not terribly new to Linux, but I am new to the forums, so hear me out! I am in the process of creating an electronic mapwall for our meteorology program, and have designed the computing system from scratch. I have two Linux Boxes, each with capabilities for 6 attached monitors...a total of 12 displays driven from two machines. My intention is to have one machine be the master...it has a touchpanel control. The inputs to the touchpanel will then trigger events for the both the master and the slave machine to display. Each of them has a specific IP address (DNS entry), and are not on a subnet.
Now...is there a way to remotely login to the slave machine and have it display on it's OWN monitors? The code is Java and which works on the master machine to animate directories of .gifs for each of the master's attached monitors. I will most likely have Java execute shell commands for the remote login (ssh), but I believe the answer lies somewhere in the X-configuration. Do I have the machines in an adverse configuration (creation of a subnet would be better)? Lots of questions...lots of desire...few answers!
I just installed Webmin on this CentOS 5.5 client and would like to know if it's possible to remotely administer the Squid server. The one I'm using for webmin is different from the one where Squid proxy is running.
I've started facing the weirdest problem. I have to restart the ethernet interface a couple of times a day and everytime i do that the server locks up completely and i have to hard reboot it.info: recently shifted to a new server, all new components and new installation, OS version CentOS 5.6
when I try to transfer files between flash drives, it starts to copy normally and then after few seconds it starts to lag. Transfer rate drops with each second by 0.2 MB down until 5 MB/s where it completely hangs. This happens to every single flash drive I put in and this is annoying because I have external HardDrive connected over USB port and I keep all my data in there, so when I try to transfer the files from the hard drive to the flash drive - it lags and hangs. Same thing if I want to copy from internal harddrive to flash drive. Although everything is fine when I copy from the flash drive to the internal harddrive and everything is fine when flash drive or the external harddrive is alone (no other flash drives or something is connected).
I am also using Ubuntu 10.04. I have tried transfering files on my netbook running ubuntu, because I thought that it might be a USB port issue but the same thing happened on the netbook too...
I am running an old p4 system with the latest ubuntu. It has been working wonderfully until today. It all of the sudden starts to hang when copying or even just accessing files from one specific hard drive. I have read that this is an error with ext4. Is there anyway to fix this?
It would be extremely difficult for me to transfer all of these files over if i don't know whether or not it will hang.
I currently have a problem in running rsync on 64 bit Debian Jessie (although the problem also occurred with 64 bit Debian Wheezy)I am trying to use rsync to archive my home directory (which is on a hard disk) to a USB memory stick. The home directory is about 18GB in size and the memory stick has 32GB.
Unfortunately, rsync hangs after copying a certain number of files and the process eventually has to be killed. Rsync was rerun but hung again at about the same point as before.This has now happened several times. Each time the hang occurs at about the same point.Use of strace after the hang shows that rsync appears to be processing a pdf file at the time, although not always the same pdf file.I originally had the rsync hang problem on a PC which ran 64 bit Wheezy and which used a USB 2.0 port.
I now am running rsync on another PC, which runs 64 bit Jessie and which uses a USB 3.0 port..I have also tried three different USB sticks, two from one manufacturer and the third from another manufacturer.All give similar rsync hangs.
I am attempting to migrate from Mandriva to Ubuntu and attempted to install the 11.04 and 10.04 CD distos on a 7-year old computer (Elite Group L7VMM3 motherboard, 1.4 ghz AMD Duron, 1.2GB RAM, 40GB IDE HDD).
The 11.04 installation CD makes it through the HD partitioning (erase everything), Computer name, time zone, and keyboard detection, but hangs after starting the "Copying files" stage of the install. The progress bar stops just below the in "Copying files...".
The 10.04 installation CD makes it through the "Installing the base system", "Retrieving console-terminus" with the progress bar stalled at 6%. Although the computer is old, Vista successfully installs on it.
I have Centos 5 Installation with following Linux ipmpls.mobilink.net.pk 2.6.18-8.el5xen #1 SMP Fri Jan 26 14:42:21 EST 2007 i686 i686 i386 GNU/Linux. I have Nagios running on it for monitoring switches. It also runs postfix to give email alerts in case of a switch is unreachable. The problem is that the server hangs for a minute and returns to normal operation. During this period if a switch is polled it cannot be reached and hence Nagios shows the Flapping state on the switches. I need to understand as to why the server hangs
I have configured openssh 5.8p2 with centos 5.6. My sftp is working fine with chroot environment but i am having problem with SCP. I am dealing with muliti Redhat servers. When i try to transfer data from other linux server through scp it gives connection refused. For e.g ssh 5.8 is configured on new server and i want to transfer files from old server which is using openssh 4.3 version.i created same username and password on new server as on old server.My sftp users on new server has no shell access but only sftp access. When i try to scp from old server to new server it gives error connection refused. Is the below configuration only for sftp and can't scp? According to google the configurations i found are for scp and sftp. Do i need to generate ssh keys by giving users on new server shell access, once created then stop shell access again, as i dont want to give shell access permanent for security reasons? but i want to use ssh keys for more security as well.

Using the EPEL Repository, I went in and installed Cobbler to my DHCP/Gateway box.Everything went smoothly on the installation front. I went ahead and modified the cobbler settings file (/etc/cobbler/settings) to point to my server IP (same box), and then got tftp running properly. Now here's the problem.Normally, you need to run `cobbler check` to find issues and correct them. I run that, and all I get is blank. Nothing. It just hangs at the prompt until I kill it using CTRL+C.When I CTRL+C from the hanging, it states "cobblerd does not appear to be running/accessible"...
Code: [root@PalaceRedirect ~]# service cobblerd status cobblerd (pid 6991) is running...
I have Western Digital 1 TB external HDD. I had slackware 13 and it could copy data to it with speed around 30 MB/s (copy from machine to HDD) and it was cool. It's usb 2.0 as KInfoCenter says. But now in fedora 13, it's like 1 MB/s or even less (KInfoCenter still says usb 2.0). Any special mount option to set in fuseblk to speed it up? I mean something like blksize or like that?
Code:
/dev/sdc1 on /media/My Book type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
I am attempting to upgrade a system from 4.7 to 5.2 using a (now) DVD drive attached to the onboard IDE. Originally I had tried using a remote NFS image and a USB stick but I thought maybe there was a problem with the image. I can get up to the point of the installation of selecting the keyboard for the system and then it freezes and never goes any further. It doesn't appear to be a kernel panic since I can still switch between consoles.
I've got an MSI K9NGM2-FID with 14 drives in it. It serves as a file server for our backup server. It's got a secondary 4 port Silicon Image SII 3114 SATA card using the sata_sil module, and an old IDE Promise FastTrak TX2000. Technically I could have 16 drives but the 750W PS is walking the fine line on tripping it's self-breaker with the 14 drives and 7 fans. I would like to NOT have to disconnect all of this to do the upgrade.
I thought maybe that running the install using the "noprobe" option would help so it didn't detect and load the modules for the Silicon Image or the Promise cards and detect all of the drives but it still gets stuck on the step after selecting the keyboard. The installation info console and the dmesg console don't really provide any useful information. The installation console says:
INFO : moving (1) to step welcome INFO : moving (1) to step language INFO : moving (1) to step keyboard INFO : moving (1) to step findrootparts
And the last lines of the dmesg console says:
<6>device-mapper: multipath: version 1.0.5 loaded <6>device-mapper: multipath round-robin: version 1.0.0 loaded <6>device-mapper: multipath emc: version 0.0.3 loaded
Is there a hidden "debug" option that will turn on a lot of extra logging?
I'm trying to find out which application will copy DVD discs (video and data) in raw mode. Something that works for DVDs like cdrdao works for CDs. I tried using cdrdao but it errors out because the DVD disc is too big for it. I tried looking at Brasero but I can't tell if it offers a raw option. I see that Brasero lets you copy a DVD to a RAW image, then burn the RAW image back to a DVD-R. If Brasero uses RAW mode to do a direct copy, this would essentially do the same thing, but I can't tell if that is what it does. But, I think this will work.
I am working on an application in Motif and C++, which uses an XRT Table. With the XRT Table being an infrequently used product, it is hard to find good documentation on it, and one area in particular is sorely lacking... a good explanation on how to copy text from the table to the clipboard used by other X11 applications. I've come across an example application that demonstrates how to copy text to the clipboard, but I cannot seem to merge that knowledge with what I'm provided with the XRT Table API. Does anyone have any knowledge in using the XRT Table, and in particular, with copying selected fields within the table to the clipboard?
Now while installing, I had 2 Hdds. at the time of partitioning, i used both as separate Hdd and made a /backup. I used that for my backups. That was RH9. Now I want to install Centos 5. and i wish to keep the /backup as it was. (as my cron scripts and others are written in this way)I wish that it will be mounted at the time of boot. And moreover, I can add a new hdd (using the manuals) but I need to keep the data.
Also the second question:: I have implemented a WiFi hotspot in a hotel with a Cisco WLC and several Cisco APs. Now I wish to restrict and log on access for both wifi and wired LAN using user names. Raduis is okey... with a mysql password database... I found a thing named hotex hotspot billing. But that's expensive. Also FCS's module is expensive too. I do not need billing, just access control. Any ideas on this?? It must be a linux based kind of baremetal package...
I'm actually not a Linux newbie, but I'm DEFINITELY no expert either... I'm trying to copy all my data(approx 50 GB) from a usb drive(western digital 250GB) with ntfs partition in one go... The problem is that it only fails for big transfers... works fine for smaller transfers like 1Gigs or less... I have just one internal hdd partitioned into two ext3 partitions.. so I have sda1(Primary.. mount pt /), sda2(swap) and sda3(mount pt /piyush)... The usb drive comes up as sdb(sdb1).. just has one ntfs partition... I've also installed the ntf-3g drivers.... but doesn't seem to work... I've also noticed that when the machine hangs and I try to shut down, it fails and I get a message again again... (sdb1- no sense detected) or something like this... don't remember the exact message... will post the exact one if no one is able to figure out what's wrong...
I want to install Xubuntu 10.10 x64, but it does not work. While copying data the setup tells me about an Input/Output error, but i don't think there are hardware errors.
The environment:
AMD Phenom II 1055t 6x2,8 Ghz 2x 2gb ram Hitachi 1TB hard drive Two partitions: 1st for Windows 7 Ultimate (NTFS), 2nd for my Data (NTFS)
So I decreased the size of the data partition and created two new partitions beside the Win7 partition and the data partition. The first is ext4-journal (20gb) the second is Swap (4gb). I've done that all by the Xubuntu setup.
I've downloaded the image from the german mirror (TU Chemniz) and checked the integrety via SHA1. Checksum was correct. I also checked the data after burning.
I am researching the CentOS Cluster Setup. Does anyone know of a guide on this or have a thread linked that I can look at? I want to build a small cluster and then be able to add to it as it grows. Mainly I want to have web hosts, data, and mail behind it. The DNS will probably be on there own.
I am dual booting XP and Ubuntu 10.04, but in the future I will be getting a new machine and I will only be running Ubuntu and won't have access to iTunes. Because I have an iPod Touch, I have been trying to find workarounds for syncing everything that iTunes took care of in the past. One problem I have is managing movies. I have looked through various media players/iPod management tools (Amarok, Rhythmbox, gtkpod) and I am using Rhythmbox to sync my music and and attempting to use gtkpod to sync my movies.
gtkpod is able to sync songs (Tested with a few minute test clip) and short *.mp4 files (15mb I know for sure from test). I am unable, however, to get it to sync a movie (~700mb) I am able to drag it onto my iPod in gtkpod, but when I try to save the changes and write the files, it hangs at "Copying Tracks" at 0%. It eventually crashes during the couple times I have tried to wait it out. So this being my situation, my question is, is there a size limit to the *.mp4 files I can sync to my iPod Touch via gtkpod? is there any other tools that you know of that I can sync videos to my iPod with?
I recently removed windows 7 from my computer and am now only using ubuntu. I used a live cd to grow the partition to use the new available space, but now the system just hangs at the Verifying DMI pool data section of bios. This is usually the first thing before grub loads.
