Red Hat / Fedora :: System Changed To Read Only - Cannot Bootup
May 30, 2011
All of a sudden my production system changed to read only. Ran fsck and it ran for about 5-10min before it crapped out. Now when rebooting, getting an ext3-fs error, attached is an image. The system is on an ESX environment.
Sometimes, in fact quite frequently, when I boot up my system, PulseAudio does not work. ('Connection Refused'). If I log out of my normal account, log in as root, log out of root, and log back in to my normal account, this seems to reset Pulse Audio and it works again. Seems like a security glitch, but I can't be sure.
I installed F11 on a SATA 500 GB Hard drive. I plugged this HD in various computers. It worked fine.
However, when I try it on the following platform (the one I have to get it to work): (PC104 bus, AMD 1.1GZ with 512 RAM), I get a file system error during bootup.
On the other hand, the system gave the chance to enter the root password. So, once I did this, I tried to run commands "fsck -f /dev/sda" and "fsck -f /dev/sda1". The command could not find sda or sda1.
I tried the fsck on different platforms (with the same HD), it worked fine.
I returned the CPU board to the vendor, and I am expecting a new board soon. I assumed the problem could be with the board itself. But, I am not sure.
i heared that in fedora 11 with new kernel version comes ext4 as default file system. when i was upgrading fedora 9 --> 10, i just changed repos in /etc/yum.repos.d. now the question, if i upgrade my system, will my file system got changed, and if it does, will my data got damaged?
I am using the default CVS available in Fedora 9. I initiated the CVS server by cvs -d /usr/local/cvsproj init To check-in and check-out the following exports commands are used export CVS_RSH=ssh export CVSROOT=:ext:swathi@SERVER:/usr/local/cvsproj
I shall explain problem by taking an example. A project was checked in long before (for example the checkin date is 25 Feb 2010). And today (i.e. 21 June 2011) I checked out the project from the repository. After checkout, the date of the project in the repository is changed from 25 Feb 2010 to 21 June 2011. This date is set to all the subfolders in that project. But the files in the project retains the checking date i.e. 25 Feb 2010. Why the check-in dates are getting updated/changed to the system time after doing check-out.
now my system does not connects automatically when fedora start's to eth0 i have to connect it manually by pull down menu in the beginning hostnname was dbe272b22.dslam-172-17-161-245-0532-474.dsl.cantv.net i do not remember if the last part ".cantv.net" was there.... i changed hostname "dbe272b22.dslam-172-17-161-245-0532-474.dsl" maybe ending with ".cantv.net" with system-config-network for hostname "edicta" i modified /etc/hosts by hand twice, now do not remember what i did exacly but here you can see /etc/hosts
I accidentally changed etc., folder ownership, and now my computer doesn't even start up. I tried starting up in failsafe mode and changing the ownership from the root console, but somehow I wasn't allowed to do that. Then I loaded kubuntu from a live disk and I changed etc ownership to root. I thought that would clear up the mess, but apparently live disk's root is not equivalent to system's: when I try to start up the computer I get a message saying the filesystem is readonly. I'm not too concerned, because I have a complete backup, but I'd rather avoid the time of re-installing all my software again.
Something has changed all my file permissions to read only and when I try and change them back it wont let me. Is there something I can do i Nautilus to correct it?
It even effects the waste basket-all the stuff in there is now read only and when I delete items I get a file operations window, which comes and then goes like its deleted them, but they re still in the waste basket, doesnt show an error message like it does if I try and move any other file.
i was browsing one of my friend hard drive using knoppix live CD, i was amazed to find that all the folder which he uses was empty, there was no files present in them, for example there was a folder in /usr/local named web, but when i browsed that folder using knoppix it was empty.I searched for files in every partition but still no result found.
After some time when i placed hard disk back and booted the PC normally, everything was in its proper place. Then i thought to make image of the hard drive and use it on my PC, the image booted well, but still those particular files were missing. I want to know how is that possible? Is there any way to get files from the remote system during bootup?
I tend to get constant crashes when using internet browsers ( Google Chrome and Firefox ) basically the application hangs not moving in any way, then eventually completely freezes up, the system then locks up and finally crashes.
Upon system re-start I get "Read Error" at boot ( No further information, it literally just says "Read Error" ).
It is sometimes fixed by going into the BIOS and select "Hold on No Error".
I tried installing OpenBios to see if using different BIOS firmware would resolve the issue, but the OpenBios install failed ....so no dice there either.
I am trying to work out if it is a hard drive problem or if it is purely a problem with Fedora.
It was working fine for a couple of months and when it does boot up ... the system works fine, ( Until another crash ).
It seems like the internet browsers crash the system and then the system crashes and can then no longer remember how to boot up.
what this could be that could be software based....if not it looks like I will need a new hard-drive.
I just booted into Linux and the Update Manager prompted me to restart. After the restart the GRUB interface I expect to see is no longer there and now it is just a command line that says press tab for more options. I have not got a clue with shell language as I have had no time to learn it as of yet. Do I need to uninstall and reinstall Linux or is there a command that can be typed that boots up the operating system. Even better if there is something I can do is there also another command that can bring back that interface I was used to.
I have configured my system to connect to a wireless network on bootup, but now every time I boot I have to wait and watch it connect (it outputs some dhcp connect stuff) which delays the boot process. is there any way to just initialize the script and then go on with the boot process instead of letting it output some pointless crap and waiting for it to end?
On installation of my OEL (Oracle Enterprise Linux), I've made a mistake, and set the date and time wrong. It's pointing to a date far in the future. So I change the date (and time), all looks OK. But when I boot, all is back to the same date (in 2015). I'm running this OS in VMware, I don't know if this issue relates to VM or not.
I need to write a small application which needs to detect if the system time is changed by an another application/user and perform some action as soon as it is detected (maybe log the data that time has changed, along with info about which application/user changed it).
How can this be achieved?
I have good programming experiences in shell script, c and beginner level in python. I don't need to know when it was changed, just need to know who/what changed it. The system uses NTP to sync the time, but it is also possible for anyone/any application to change the time(for eg: using the simple "date" command as well).
All my torrents go to my home/username/Download/ folder, I could read/write yesterday but now I cant even copy the files to a flash drive.The error i get is "Cannot create regular file '/home/username/Download/file' : Read only file system.
I've upgrade my fedora 11 to 12 by installtion DVD and everything is fine right now.Everything is there and the new system looks good.However,my boot screen is still the same with 11.How can I switch to the new screen?
I updated to the newest kernel today ( 18.104.22.168-174.2.19.fc12.x86_64 ) via software updates and noticed there is a 10 second pause just after the grub screen goes away and before plymouth comes up. This never happened with the previous kernel. Anyone notice this?
I want to play a video thru VLC player as soon as when system boots up. is it possible using crontab or any other way to go about it??? Also I want to play a file by telneting to a remote server (eg: the file is present is /media/disk/movie.mpg). is it possible to write a script and execute them using crontab.
I am facing bootup issue in Fedora 14.I troubleshoot the bootup issue i m facing probably because I have done change the name of volumes from disk utiltiy. I read somewhere that it should be done from another place (administration option, the last menu of fedora and there is some volume/disk management..like thing that give rod like blue/red picture of disk=>System-config-lvm) rather then disk utility under system tools. I think that my LVM path is not setup..due to rename of volume..it is mismatched somewhere...that includes path...finally using rescue disk i enter in shell prompt and mounted my system using chroot /mnt/sysimage then found that my /home is empty, so done some readings and found that using mount /dev/vg_brs/home /home i am able to get my home fixed that now appeared my user and whole data.
but that is till i m in shell prompt. Don't know where and how to fix/add this line so that boot loader of fedora will take this instead of something other that it is taking and not founding resulting in failure to boot with message (in between lines)
I have a cheap usb kvm that doesn't pass the EDID data back to the computer from the monitor. And now Fedora 12 seems to rely on autodetection of the monitor to start up at the proper resolution. When I have my samsung 712N on the kvm, fedora 12 boots to only 800x600 max resolution. If I connect the monitor directly to the computer video card, fedora sets the screen resolution to the desired 1280x1024 properly.
When booted through the kvm, fedora won't let me detect or select the correct monitor, and I haven't found any way to work around the problem other than pulling the monitor off the cable, connect to the cpu, reboot. After it's booted I can reconnect the monitor to the kvm and the video is fine.
My question is does anyone know how to manually tell Fedora 12 at startup what kind of monitor I'm using and skip the bootup monitor detection? So far I've spent a couple unproductive hours with google to discover this isn't a totally uncommon problem and no site I've found seems to have any solution.
I had some problems and had to upgrade my motherboard. I chose the same manufacturer and haven't had any major problems booting into Fedora 11. (I was totally amazed by this BTW).The only thing is that I have 8 GBs of memory in my computer and System-monitor now says that I only have 3.2. Lastly my nvidia driver which is working correctly, is giving errors about python at bootup. Something about glib being presentAnother weird thing is that GRUB will not let me interrupt it either during normal usage nor with a live CD loaded. This also started happening after I installed Fedora 11 on my old board.
When I went to start up the computer, the kernel usually hung at the same place on boot up, although sometimes it booted just fine. The default kernel is 22.214.171.124-174.fc12.x86_64. It's boot up arguments are:
I also have kernel 126.96.36.199-37.fc12.x86_64, 188.8.131.52-145.fc12.x86_64, 184.108.40.206-127.fc12.x86_64. I have seen the same behavior out of all four of them. Last night I ran Memtest86+ all night. It took eight passes with no memory errors. As far as hard disks go, I have two Seagate Barracuda 1.5 TB drives operating as software RAID 1 (mirroring). One of the drives does have three bad sectors. The motherboard is an Asus P6T6 WS. This morning I plugged in the GP diagnostic chip that came with it, but I'm not seeing a whole lot useful there, except that now it is just displaying "FF" non stop.
I did some poking around on the web, and it looks like "FF" is supposed to mean that the CPU isn't properly seated, which makes no sense because the system monitor software is detecting all four cores perfectly, and I have no other odd behaviors anywhere else. At this point I'm rather at a loss to understand what could be causing the difficulties. Sometimes any of the four kernels boots fine, and sometimes they don't. The funny thing is that on the blue "boot progress bar" all four kernels hang at exactly the same spot if they hang at all. After doing some more poking around, I'm relatively sure that "FF" does NOT mean that the processor isn't seated correctly. I'm going to try contacting Asus and see how far I get towards getting some good info on what the diagnostic codes mean.
I've been able to get a laptop on Fedora 14 (220.127.116.11-48) working with a Netgear WNA1100 Once up and running, I execute "ifconfig wlan0 up" from root, and everything connects just fine and is stable as long as I stay logged in. But, I haven't found how to do this automatically on boot.
I've tried to use NetworkManager, but I cannot figure out how to get the GUI to show up - it says its running and enabled in the Services gui, but I haven't figured out how to actually use it! I checked to see if the nm-applet is running with ps, and for the user login, I see:
I'm not sure if the "sm-disable" flag is my problem, or how to change it. I'm not even sure if NetworkManager will allow me to set things up for bootup, but that is the path I ran down...
I assume this is a fundamentally easy process to set this up on bootup, but I'm not stumbling across the method. I recall doing this kind of thing years ago when I was an engineer, and before I got my lobotomy to become a manager...
I have a problem where the volume in F15 is way too loud. The computer is a Dell Optiplex Gx280 using what is labeled as an Intel ICH6 for the audio card. I have the system volume at about 10% and have to still keep banshee's volume at 5% or lower otherwise it's just too loud. The system saves the volume level between reboots, however I've run alsamixer and noticed that the headphone jack is at max volume.
So, I ran: Code: sudo alsamixer -c0 lowered the headphone jack volume by half, then ran Code: sudo alsactl store 0 to save that setting. Upon rebooting, the headphone jack is back to 100%, though.
If I run Code: sudo alsactl restore 0 then it will restore the settings I saved but it obviously isn't doing this during bootup. How would I run this command at boot?
We are brand new to the Linux platform and just learning. So this is what we have done so far, Installed RHEL 5 on a test machine. Says it was succesfully installed. But when it boots it boots to a blank screen with no prompt or gui or anything just a black screen. Does not accept any input or anything.
We are able to get into the GNU Grub and this is what we see
I can enter b for boot
We would like for this to boot to a GUI interface.
I bought a new SD card which I intend to put some MP3s on - except that I can't write to it because it tells me the destination is Read Only. No-probs thinks I: I'll just reformat it.
"Error creating file system: helper exited with exit code 1: cannot open /dev/mmcblk0p1: Read-only file system"
Various chmod commands all result in Read-only file system. I tried umount then mount commands, but it couldn't find it to mount once I'd unmounted it using the same /media/ file path (I assume it's the only one).
