CentOS 5 :: Hdb: Timeout Errors After Power Off Only
May 4, 2010
The problems I was having earlier: [URL]seemed to be solved.
I was not getting any error messages after restart. I should have powered down fully, but did not think that it would make a difference. :(
The same issue is again occurring, but after shutdown ONLY and only on the first boot. After the first boot, a system restart will not cause any error messages. (I have rebooted at least ten or twenty times to make sure)
But after a system shutdown, the first boot hangs up and I get the
"Red Hat nash version 5.1.19.6 starting hdb: timeout waiting for DMA hdb: drive not ready for command"
errors five or six times before each boot. Also the system boots very slowly the first time.
I used the getinfo.sh all command and posted the info to the suggested site here: [URL]
Is it possible this could be a hardware issue? This is an old salvaged HDD. Ive changed everything I c an think of in the BIOS with no results.
I have used the hdparm -d /dev/hdb command and verified that dma is not being used on initial boot or after a shutoff but IS being used after a reboot...
here are the HDD settings
/dev/hdb:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
I am a complete novice when it comes to Linux, but want to learn, and installed CentOS5 on an old P4 Dell I had lying around. Dell Dimension 8100 BIOS is version A02 Install seemed to go fine, but when I power up I get the following message
Red Hat nash version 5.1.19.6 starting hdb: timeout waiting for DMA hdb: drive not ready for command
this happens a few times each, then CentOS finally loads.
If Im understanding this right, DMA is direct memory access. Is it possible the hard drive, motherboard etc does not support this?
My spouse bought me a Seagate BlackArmor NAS 110 recently, and I finally had time to connect it to our home network. I have samba installed, and my linux box (opensuse 11.1) can see the NAS, but when I try to open the network connection I get a "timeout on server" message. I bumped up the network connections, but still no luck. The odd thing is that last night I was able to connect and see the public folders for awhile. And her Windows Vista computer seems to connect without a problem after using the seagate software.
I'm no network admin, and have exhausted my resources on this.
I'm using natty, and in power management settings the maximum time I can set to put my pc on sleep after being idle is 2 hours, how can I increase this time? I need to put it on at least 4 hours.
A couple of days ago on my Fujitsu Laptop which was nearing its end (in about 2 more years, I'll have to send it to the scrap pile) I had a GNOME Power Configuration error. This is the story of my struggles and my thread of cries for help: I was booting after installing an update for Maverick Meerkat, and I got a message during the load screen that said: INSTALLATION PROBLEM: The configuration defaults for Gnome Power Manager have not been installed correctly. Please Contact your system administrator.
So I dropped into GRUB During my 5th boot (while trying to boot once more in hopes it was just a boot error) and I selected the latest/updated version of Ubuntu, but I dropped into the recovery mode version so I could attempt some commands to try and fix it. Then, I dropped into the root terminal to attempt more commands to avoid specifying my networking device, and typing sudo before the commands. I got on my alternate computer and searched my problem. I installed a whole bunch of crappy commands that didn't do anything, and ended up purging GNOME completely and doing:
pulled up an old clunker and put centos 5.4 on it the other day. well the grub spash screen appears but i have to manually hit enter to select a kernel.at the /boot/grub/grub.conf file and timeout=5. this is a new install. so I tried changing that value to 0 and it does boot the kernel immediately but never displays the splash screen. so something is not right I assume. btw I see a message (loading stage 2) for about 20 seconds as the computer boots and I have never seen that message on my ubuntu machine, so I wonder if something is off there.
I set the default os to boot as windows 7 with a timeout of 1 second. I thought that this would be enough time to switch os ubuntu when i need to, but I am unable to. How can i reset the timeout to 3 seconds? I also cannot view the ubuntu partition within windows because of ubuntu's file system.
I have centos 5.3 server and the problem is the ssh timeout time set to 10 minutes of inactivity. I want to set the timeout to 1 hour, how can I set the timeout time?
One person using our DNS servers reported a very curios problem. When he tries to access [url] he gets a timeout error. I tried loading the site using chrome, firefox and ie8 and I get the same results.
I am having a problem with 5.4 that I did not have with 4.5. The problem happens only sometimes but in specific instances. Basically a summary of the problem is that certain network transactions timeout. The specific instances are with wget, rpm, http. The problem usually, but not always, occurs with pptp stuff. (NOT running pptp but getting pptp stuff). For instance, the following command, which finishes in seconds on non-5.4 OS's: wget [URL] downloads about 20% then gets stuck. About 5 minutes later it downloads another 20% and then gets stuck, etc. The same thing with rpm: rpm -ivh [URL] waits about 3 minutes and then gives an error. I think it does the same thing as the wget but wget will keep trying, while rpm gives up. The error from rpm: Retrieving [URL] ..five minutes later:
I can wget the above as I mentioned before and install it that way. Before I do it, yum works fine. Afterwards, yum exhibits the same behavior of timing out (because it is using the pptp repository). Also visiting the pptp web site from Firefox times out on certain pages. I originally thought it was some problem with the pptp site, but I notice that log into hotmail.com. Does the same thin (fine on other operating systems). A view with Wireshark on the wget (pptp) shows the my machine receiving a reassembled TCPPDU from 216.34.181.96 (Sourceforge), sending an ack, receiving a reassembled PDU, sending an ack, receiving, sending followed by the 5 minutes or whatever of nothing. Then sourceforge sends an RST and a SYN and the process is repeated.
When I put the machine directly on an AT&T IP connection (12.147.X.Y) everything worked fine. Same with Comcast on a direct link. The times I am having problems is when our router is hooked up to a Comcast IP (70.88.X.Y) and assigns 192.168.5.X addresses to our machines. So when I was doing the above from 192.168.5.27 going through the router through Comcast is when I had the problem. So it is probably something with the router, but it is hard to figure out since CentOS 4.5 and Fedora do not exhibit this behavior, nor does 5.4 on most sites (mail.yahoo.com for instance). I did verify, at least from what I could, that ICMP type 3 and 4 are not being blocked. If they were, the same problem would happen on other op systems. And I was able to ping, albeit just locally, but we looked at the router settings and ping was not blocked.
I have Centos 5.1 and im a total newbie. I have managed to get it running with Apache and PHP but after I install mysql it fails to start with the above error. I have removed it as well using YUM and reinstalled it but it still will not start.
I'm trying to get the options for rotate timeout to work and it does not.Timeout always seems to defaults to 1 sec no mater what value I set it to, which is fine but still the option does not work.I'm setting these according to the manpage for resolv.conf, please Let me know if I'm missing somethingHere is my resolv.conf file
I built a home server (NAS/WWW/SSH/media server etc) and chose CentOS 5 as the OS (stability, easy of configuration).I was just about to start tuning the power consumption when I realised that the kernel CentOS uses is so "old" that it does not support the latest reduced power consumption enhancements that Linux has achieved in big strides in the recent past (we are probably still talking 6-12+ months ago e.g. tickless kernel)..
So my questions; 1) I know CentOS was maybe not meant for home servers (certainly its not its primary purpose), but if it is, any ideas of what kind of power consumption it takes (I know its relative) and if there are particular power consumptions that are worthwhile?
2) Do you recommend me compiling my own 2.6.21+ kernel from kernel.org or am I just likely to have compatibility issues (I really did not want to do that) or when is CentOS 5.4 supposed to have a newer 2.6.21+ version kernel?
Was it wrong of me in principle to choose CentOS for a home server when I am power conscious? (I don't have a low-power VIA processor either but a P4 so I am really just hoping to make do with software changes).
I was having a problem on my squid server whereby 1 website would timeout daily and return a nscd not found error: [url]....There may be other sites but this is the only one I know of. A selection of other sites still work correctly, which is the strange thing.I have found that by restarting the dns cache everything works again: /etc/init.d/nscd restart.I never know quite when this will timeout so it is not very good for people accessing that site on the server.
I have a VPS running on centos-5-x86 and mysql server went down two days ago this is my mysql server log

I try to set up a 5 nodes cluster and a shared Coraid Storage with conga but it fails with "Shared Storage Support" checked.The message is:'A problem occurred when installing packages: Packages of set "Clustered Storage" are not present in available repository' and it is shown under every node on the next sceen after I submit.The pc where conga runs is on the same subnet (192.168.xxx.xxx) and it has the same /etc/hosts of the other nodes.In that pc runs a proxy too and the nodes go out through it (that pc has 2 NICs)Every node (2.6.18-128.1.14.el5-xen-x86_64) is patched whith the last yum update (this morning) the same is for the pc (2.6.18-128.1.14.el5).Every node has 4 NICs , 2 NICc towards the storage the others in bonding towards the WAN.Every node is exactly alike, they have been installed with the ks.cfg generated from the first node and they all have the support for Clustering, Virtualization, and Clustered Storage.
I have installed vnc-server on my CentOS 5.6 virtual machine. I can connect to it with a java web browser so it seems to be working. However, I get the following error message when I start, stop or restart the vnc-server process. Quote: Starting VNC server: 1:ken xauth: timeout in locking authority file /root/.xauthkk661q
I had a power failure the other day and my server shutdown abruptly. After bringing the server up I noticed that the /var partition came up as read only. I was not able to edit the crontab, not able to write to files within /var/log/ and do other write operations within /var.
I did a mount and it showed that /var was mounted read and write but when trying to run certain operations the system was still saying that it was read only.
This OS is has been cloned from the drive of another computer. The motherboard is now an SIS730. I assume the hardware is sufficiently different to prevent the OS from shutting down the computer.How do I fix this? ---without installing, if possible.
I have built a Centos 5.3 server for a friend of mine that is being used as a NAS server. The server has 4 1TB drives in a RAID 5 configuration and a dedicated non raid system drive for the OS. My friend isnt very Linux literate so I need this bow to be relatively simple. I have worked most of it out but have a question with regards to remote reboot.
I need to be able to shut this device down through the power switch without human intervention (at the moment when the power switch is pushed the server asks to confirm shutdown) the server wont have a Monitor connected so this isn't practical. Is it possible to use the power switch to do an clean, immediate shutdown?
The other option is shutdown through a web page is this something that has been done before? I know he can do it through terminal by issuing a shutdown now command but as I said this guy wants something simple. I don't really want to explain everytime he needs to shut the Server down how to do it if he can just do it via a website or even with the power button.
I'm not sure this belongs in this forum as opposed to the hardware forum, but I do not beleive this is a hardware issue.I want to stop the scrren from blanking and going to power save. I'm running 5.3_x86-64 and I'm using the nVidia drivers direct from nVidia called NVIDIA-Linux-x86_64-96.43.13-pkg2.run.
So far, I'm added DPMS off in /etc/xorg.conf, removed all the screensaver packages and all the power management packagesbut the screen is still going blank after a time of inactivity.What else do I need to do? I can not allow the screen to go blank, there should be no screensaver or power management and the machine should stay in a completely awake and ready-to-use state at all times.
Before to describe my problem I want to say that I searched a lot on the internet and I think I tried all the solutions provided by other users to similar problems.
I've got an IBM xSeries 346 server running CentOS 5.5 with all updates applied with yum.
The video card is an ATI Radeon (lspci says: 01:06.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]).
Everything worked fine until a bad day where there was an environmental power failure and the server crashed.
I turned it on, I manually check the file system, some files went lost and after the reboot the X server didn't start.
After the first boot I had problem with /etc/rc.d/rc.sysinit, sbin/multipath.static and /dev/cpu/microcode, I solved them and now the message it shows is:
"Failed to start the X server (your graphical interface) It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?"
I choose OK and it appears an empty log, if I go in /var/log/gdm and I do an ls -al:
total 0 -rw-r--r-- 1 root root 0 Oct 28 04:44 :0.log.4 -rw-r--r-- 1 root root 0 Oct 28 04:44 :0.log.3 -rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log.2 -rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log.1 -rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log
So a lot of empty log files.
I press enter on the OK that appears at the bottom of the screen and it says: Would you like to try to configure the X server?
I choose Yes, I enter the root password and appears the following messages:
Couldn't start X server on card 0 Couldn't start X server with old config, trying with a fresh configuration
Then another messages:
Trying to restart the X server, I press enter on OK and it loops the initial message ("Failed to start the X server...)

I've made a CentOS 5 x86_64 setup last year, around november/december.This system is supposed to operate as a home router/gateway, firewall, nas, small intranet/extranet server and media center.I've previously built a system using older parts (Pentium III 866MHz), and had on it CentOS 5 x86.It successfully served the same purpose (except nas and media center) for quite some time, about 1-2years, until i felt i needed better hardware (more memory, speed and disk space mainly) and 64-bit support.
Part of this intended setup isn't finished (router/gateway, firewall, media center), partially because i'm still lacking a good 1000mbps switch and a supported wireless n 3-antenna card in AP/server mode.In the previous setup, i had router/gateway, firewall and small intranet/extranet server working, with a crappy 100mbps switch (the switch is broken now).the new setup has run pretty well, it had been upgraded 2 times, etc...But since it has been installed, even before any updates, upgrades or repo additions, there has been always warnings/errors during kernel boot.I'm listing my specs, configs, versions and logs bellow. all the partitions, RAID and LVM were created during CentOS initial setup.
I had a server with CentOS 5.5 and Asterisk fail today most likely due to the power failure. I guess the stupid electrician turned the power ON and OFF multiple times while changing the burned out fuse without unplugging the PBX. It was set in CMOS to power back on when there is power outage so my two HDDs which were set in RAID-1 now shot.
Trying to start the system and it goes through some check and fixes and then tells me to do Ctrl+D or enter password and run fsck. I have tried both methods and I don't think they yeild anything.
Ctrl+D reboots and same store again with the system fixing and asking me to Ctrl+D again. Putting the password and doing "fsck -y" gives many errors and it fixes it and then it just keeps looping. I am afraid this is making it worst than better. So, after few loops I did few more restarts and just give up. Took out the HDDs and installed new ones and install CentOS+Asterisk so business runs as usual on Monday.
However, I am kind f*ked if I don't get the files out of these HDDs. This is my first time using fsck and also encountering this type of a problem. What is the normal procedure when fixing inodes misplaced in a case like this? and what should I do to at least be able to grab my files?
I have already connected one of the drives to Windows and used Disk Internals (which maps Linux drives) but I see only folders with no contents except for /tmp/ which has contents. While the HDDs were in the system I could actually browse files and they were fine. I am really keen to get the drives fixed but I am also afraid that bad usage of fsck might replace lots of files and burn it all.
I no expert and this was a bit of mucking around. Installed Version 5 dot something on a desktop (DELL OptiPLex) with a couple of extra HDDs, for a server to play with (samba to Windows). I used the drives as a single logical drive via LVM.
We had a power cut, now it doesn't work. In fact it's been hanging around for a couple of years and before I dump it I wonder if there is any chance of getting some of the wife's letters, pictures, etc that I promised I try and get off.
The /boot partition seems to be there and I've attached a photo of what happens at boot, and I admit....I haven't a clue what it all means. Also I did not think ahead and did not create a recovery disk. I know, I know heap damnation on me for being so reckless, but any chance I can get myself back in the wife's good books?
