Btrfs: System won't boot anymore after unclean shutdown

Hi,
I have a problem with my ArchLinux (kernel 3.19.2-1-ARCH).
I have my root partition as BTRFS and no /boot partition.
After an unclean shutdown the system won't boot anymore.
GRUB loads the kernel and the kernel starts but it hangs saying: Mounted /dev/sda3 on real root.
Then, I have to start a Live CD and do:
btrfsck /dev/sda3
After that the system boots correctly.
I've tried adding fsck to the HOOKS in the mkinitcpio.conf file and in fact it tries to fsck the filesystem (but with BTRFS, fsck.btrfs doesn't work...)
What can I do?
Thanks

I'm also having this problem. I tried booting up the netinstall image to debug it, but I can't mount my btrfs volume from there either: mount just hangs. After a while, the kernel goes:
[...] INFO: task mount:612 blocked for more than 120 seconds.
[...] Not tainted 3.19.2-1-ARCH #1
[...] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
[...] INFO: task btrfs-transacti:636 blocked for more than 120 seconds.
[...] Not tainted 3.19.2-1-ARCH #1
[...] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
From this post I guessed that I might just need to wait so that I could defrag the volume once it was mounted, but it's been hanging for over 15min now (the message above continues to come up periodically).
Like the OP in the thread I linked to above, my btrfs volume is inside an LVM volume (which is on dm-crypt). Don't know whether that's relevant.

Won't boot anymore after nvidia-xconfig

Hey Guys,
Got a problem with my Arch Linux here, hope you can help.
Today I tried to install the official Nvidia Driver and BumbleBee following along the great Wiki on this topic.
Everything worked just fine and I also could run optirun gfxgear or somemthing like this.
I wanted to switch to the Nvidia Settings in the settings menu and it told me to configure my xconfig and restart x so I typed nvidia-xconfig in the terminal and it gave me an success output.
I restarted my system and now it hangs on the graphical thing I think. It won't boot anymore.
Hope you can help me out.
Thanks alot
Edit: My Nvidia Card is a Nvidia GT 740M if this matters
Last edited by Whitz (2015-02-09 11:02:41)

No, I have a laptop with 2 graphic cards an intel hd4000 and a nvidia gt 740m.
I ran the Arch Linux installation well until I tried to get the nvidia gt working with bumblebee.
I followed the wiki of the bumblebee topic and it worked well. I wanted to switch into the nvidia settings and it told me my x isnt configured properly and I should type nvidia-xconfig and restart X.
After the restart it won't boot to the graphical interface anymore.
Hope this cleared up the things
Also I dont get any errors but it just wont load..

IMac won't boot anymore after power cut

Thanks to the great storms in New Jersey, my iMac does not boot anymore after a power cut. Does not get past the apple logo screen with the spinning wheel and keeps rebooting every 2 minutes.
I was able to mount the HD via Firewire on a host machine and the disk seemed fine.
I booted from the Install disk and ran Disk Utility - seemed fine though I could not verify the disk permissions ?
One other thing - I seemed to remember the white light (front bottom right) was blinking before during start-up. Now it goes and stays black after couple of seconds.
Help please,
Philippe

HI Phillipe and Welcome to Apple Discussions...
If you haven't done so, try running the Apple Hardware Test.
http://support.apple.com/kb/HT1509
I doubt repairing disk permissions can't help this problem. It sounds like a hardware issue.
*"I booted from the Install disk and ran Disk Utility - seemed fine though I could not verify the disk permissions ?"*
When you ran Disk Utility via Firewire, did you actually Verify the hard disk for errors?

Sol10 won't boot anymore after patching

Hi,
I tried patching (Recommended patches of 1/1/2008) an old Netra T1 running Sol10 while running in multi-user mode (yes, I'm that stupid). Unfortunately when I rebooted the server it won't come up again all I get is:
Netra T1 200 (UltraSPARC-IIe 500MHz), No Keyboard
OpenBoot 4.0, 512 MB memory installed, Serial #51796331.
Ethernet address 0:3:ba:16:59:6b, Host ID: 8316596b.
Executing last command: boot disk
Boot device: /pci@1f,0/pci@1/scsi@8/disk@0,0 File and args:
SunOS Release 5.10 Version Generic_127111-05 64-bit

Use is subject to license terms.
/kernel/fs/sparcv9/specfs: undefined symbol 'stralloctty'
WARNING: mod_load: cannot load module 'specfs'
(Can't load specfs) Program terminated
ok
Trying a 'boot disk -s' or 'boot disk -r' doesn't make any difference.
Unfortunately the server is located in another country so booting from cdrom is not an option. I only have serial and network access (limited by a firewall that I don't control so remote booting is not an option either).
Anybody any idea how I can boot my server?
Thanks in advance,
Nico

I think a call to Sun is in order... however I do have a long shot you could try (at your own risk or course :) )
I checked a Solaris 10 system and confirmed that stralloctty is used by specfs (sparcv9)
I then check the 32-bit version on specfs and it doesn't use stralloctty...
You could trying booting the server in 32-bit mode instead of 64-bit while this wont solve the problem is may let you boot so you can fix it....
"........To get the image to install switch the machine to 32bit mode (not supported for newer machines). To set the mode, halt the machine and at the ok prompt type setenv boot-file kernel/unix
To change the machine back to 64bit mode type the following at the ok prompt: setenv boot-file kernel/sparcv9/unix........"
NOTE: I have not ever tried this so I would test it on a machine you have locally first!!!
BTW: I don't think patching in multi user is stupid, I think if you do it (and I do) you need to quiesce the system and make sure you have a backout plan e.g. detached mirror.
I am guessing something went amiss in the patching and the kernel is stuffed i.e. half applied patch

System won't boot - stuck after kernel timezone

Hello all,
I am new to Arch linux and I have finally decided to install it today. I think the installation process went well, I had to change a few things with grub and managed to get it to work...but....
The booting process gets interrupted right after the line that says:
:: Adjusting system time and setting kernel timezone [DONE]
Then, I see my hdd light blink for a couple of seconds and after that, it just hangs there forever.
Now, I am kind of wondering what the next step in the boot process is so I can have clues as to what is failing, any thoughts?
Thank you
Francois

I have no suggestions, but what comes next is:
Starting UDev Daemon [DONE]
here's the code from rc.sysinit:
if [[ $HWCLOCK_PARAMS ]]; then
stat_busy "Adjusting system time and setting kernel timezone"
# enable rtc access
modprobe -q -a rtc-cmos rtc genrtc
# If devtmpfs is used, the required RTC device already exists now
# Otherwise, create whatever device is available
if ! [[ -c /dev/rtc || -c /dev/rtc0 ]]; then
for dev in /sys/class/rtc/rtc0/dev /sys/class/misc/rtc/dev; do
[[ -e $dev ]] || continue
IFS=: read -r major minor < "$dev"
mknod /dev/rtc c $major $minor
done
fi
# Adjust the system time for timezone offset if rtc is not in UTC
# 1. Make creation time on udev nodes sane (FS#8665)
# 2. Filesystem checks can depend on system time
# 3. This also sets the kernel time zone, used by e.g. vfat

My MBP won't boot anymore after "repair disk" and "repair disk permission"

My 2011 MBP 15 with Lion stopped working after I attempted to use Disk Utility to "repair disk" and "repair disk permission".
It was having weird issues before I attempted the repairs, it was freezing every few seconds no matter what I am doing, the whole thing would freeze with only the mouse movable. then after a few seconds it goes back to normal again. This happened after I downloaded and installed some updates from Apple. I don't know if the updates would cause this or it's something else.
In Disk Utility, "Repair Disk Permission" took 5 hours. While "Repair Disk" resulted in "Disk utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files".
Now when it boots, there's a loading bar under the Apple logo, it loads half way and shuts down itself.
I can still get into CMD+R Utilities though.
Any idea how I can extract the data out of the disk? I'm going to format and do a clean install.

A stopped loading bar is indicative of a failed firmware install that didn't complete, it's trying to install and is failing.
Do a PRAM reset
https://support.apple.com/kb/HT1379
Reboot into Safe Mode, (shift key down) then reboot normally and see if that fixes the issue.

You may have to try to reinstall your firmware manually, you'll need another disk burning Mac
Find your exact firmware(s) here (or on Apple Downloads page)

Lastly it could be your boot drive is failing or something wrong happened with the update and accounting for all the to the other issues.
A OS X "overwrite" may solve the issue, may not.

K9N SLI System won't boot anymore

Hi!
My system was working fine until I switched it off yesterday. Usually it is switched on for quit a long time, several days or sometimes even weeks (Stuff downloading etc.) As I first built the system I had some temperature issues, but a cool big Zalman CPU Cooler and some well placed Fans in the casing solved it. For three, four months it has been working fine.
But, since it is pretty hot over here the last few weeks I decided to switch it off at night so it wouldn't produce so much heat in the room. The next day as it wouldn't switch on I noticed that the Power LED was still burning, although everything else had shut down.
Does anybody know what this could be?
I already reduced the whole thing to the bare nescessities to find a source for the problem. Regretfully it doesn't change anything. As soon as I switch the power supply on the Power LED starts to burn and nothing else happens...
Does this mean the MB is a goner??? And if so, why suddenly now, after working fine for several months? Or maybe the CPU? I don't have double parts so I can't test other components. And again: why now after functioning perfectly?
The specs:
K9N SLI (MSI 7250 V. 2.1)
AMD Athlon 64 4600+ DC
2x OEM 1GB DDR2 667 MHz
2x Winfast PX7600GT in SLI Mode
Latest available BIOS & Drivers (LIVE Update)
The last temperatures I saw were around 42 Degr.Celcius while on but idle and around 51 when active (games etc.) so I wouln't expect that to be the prob.
Thanks for any useful help!
Willem

Well, the question about the PSU made me take a good look at the thing and it turns out it is a dual rail PSU or whatever they call it. When I was looking through the forum for similar problems I noticed that a lot of you out there hate those because they more then once cause problems...
Since I didn't have any way to check the PSU I yust bought myself a relatively cheap one, single rail, with 420V and what do ya know... It now works perfectly again.
I don't know if the current temperatures have anything to do with it but maybe the heat was too much for the other one but it just caused a startup problem. Since the system had been running for a while I got stuck with the problem when I switched it off......
Anyway, I start looking for a decent PSU now. Henry, Thanks for setting me on the right track!

Powermac G5 1.8Ghz June 2004 won't boot anymore

Hi all,
Past week i've bought a second hand PM G5. At first it seems to be all ok, but right now its not working anymore.
I've managed to install the OSX on the first evening i've had the PM G5. After installing evrything seemed to be fine. But after 30 minutes surfing on the internet, it froze. I had to give it an hard reset by holding down the power button.
After turning it of, it won't boot anymore. after a few times trying with 10 secconds between it, i unpluged the powercabel for 2 minutes. Wile turning it on after 2 minutes, it was booting , but it stopped booting after 1,5 minute and froze.. after hard resetting it, i've managed to boot it right. The OS seemed to be ok again, but after 5 till 10 minutes it froze again.
Right now it won't boot anymore... it starts (without the front light, this light only blinks fast once i turn it on, but after that no more. Sometimes it won''t even flash.
I've been buzzy replacing some components to get to know if it was a hardware fail. I've first replaced the PSU with two other PSU's from the PM G5, but won't do a thing.
The i've replaced the memory with 4 kind of difrent pairs, but won't do a thing either. At last i replaced the Logic Board, this won't even do a thing about it.
Of course i replaced the PRAM battery first, but also this won't help me.
I've tested it in AHT, but evrything was working well, according to AHT. I've managed to get the system log, but nothing scarry though here also, only some 122 errors some times. (download the system log here: http://www.mijnbestand.nl/Bestand-F4DDN66WLRCI.log )
I've reset al things possible like PRAM reset, PMU reset. Nothing seem to be working.
What can i do next to get this thing work?? I'm getting nut's here..
Please help..
Thanks a Lot
MArtijn Snoek

Hi martijnsnoek, and a warm welcome to the forums!
Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
http://support.apple.com/kb/HT1547
So, with the info you given, two things come to mind...
Bad solder joints around the RAM slots, try heating that area with a Hair Dryer for 3 to 5 minutes, then see if it starts.
If you can get it running, Get Temperature Monitor to see if it's heat related...
http://www.macupdate.com/info.php/id/12381/temperature-monitor
And/or iStat Pro...
http://www.islayer.com/apps/istatpro/
If you have any temps in the 70°C/160°F range, that's likely it.
BTW, have you blown the dust out of it since you got it?

Won't boot anymore but in safe mode

My laptop won't boot anymore. I get a gray screen with a prohibition sign. Here's what I found so far:
If I boot in the verbose mode it gets stuck on something like Looking for boot device.
I zapped the PRAM. Didn't help.
I can boot in safe mode.
I used Disk Utility to check the drive and permisions. Everything ok.
I can't boot from the original Snow Leopard DVD. I press C, the drive spins then stops.
I reinstalled Snow Leopard from the safe mode. Didn't help.
In safe mode Safari is crazy slow. Firefox runs full speed.
Any idea?

Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
Unless you can boot from your installer DVD there's nothing you can do to reinstall OS X, so I'm not sure how you did reinstall as you said.
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.

When I turn it on, the HDD makes click and click and the system tries to boot from DVD, from USB, from HDD, from IPV4, from IPV6 and then it says, that there is no bootable device.
Unfortunately I wanted to make the +Windows 8 Restoration-/Rescue-DVDs+ this weekend!
Huh!!!
Well, I still have an *+original Windows-7-DVD and license+*, which would be good as well (I used it the last years).
*YET*, I cannot install *+Windows 7+*.
It says something like that, that +this system is not available for Secure Boot+.
I read about "Secure Boot".
So I pressed F2, turned the laptop on and could with this reach the BIOS.
It is a *+InsydeH20 Rev. 3.7+*.
*BUT*, when I go to "Boot Mode" I can only see, that this option is greyed and I cannot change from +UEFI Boot+ to +CSM Boot+.
Even the change of the HDD made no difference.
I put in my old HDD with Windows 7 installed (wich works in the other laptop), but the system won't boot, for it is +not suitable for Secure Boot+.
*So, WHAT NOW?*
I mean, it cannot really be the Toshiba politics, that you need to throw away your laptop, if the HDD breaks, can it?
For I didn't create the Rescue-DVD, I have just my Windows 7 DVD and another HDD with installed Windows 7.
Do I need to buy another Windows 8 licence and another HDD, to install Windows 8 (suitable for Secure Boot) again?
Would it even work like that?
Or is there any chance to upgrade the BIOS, for that I can then change from UEFI Boot to CSM Boot?
Or is there any other chance, to use my other HDD with Windows 7, or at least a new clean HDD, on wich I then can install my Windows 7 OS?
I hope, that someone can give me any good advice, what to do now ... without throwing the Toshiba laptop away ;)
Thanks in advance!

If the HDD died, in needs to be replaced.
If notebook is still covered by warranty, the HDD will be replaced free of charge. If warranty isnt valid, you will need to pay for the new HDD.
I think this understandable.
_Now some facts about the Recovery disk._
If you did not create a recovery disk in the past, you could order the recovery medium on this page: http://backupmedia.toshiba.eu/landing.aspx
The recovery disk would install the Toshiba image and would set the notebook back to the same state like at the first day of purchase.
_Regarding the Win 7 installation:_
Usually to install the non UEFI capable system, the secure boot needs to be disabled and boot mode needs to be set to CSM mode.
If this isnt possible you should update the BIOS but to do that you need an running Windows system (Win 8).

Mac mini won't boot anymore

My Mac mini won't boot anymore. It's been running fine for months.
It's running Leopard Server 10.5.2 Build 9C31
It starts to boot, I get the first spinning gear with the gray screen, then the blue desktop blinks, then a second spinning gear on a gray screen and it appears to hang (the gear stops spinning).
I booted off the install DVD, ran disk utility, repaired the HD, repaired the permissions: the behavior is the same.
Safe mode doesn't work (same hang as above).
Single user mode does work.
I can connect to it via Server Admin while it appears hung.
The last few lines of the system log are:

Any ideas?

Yes, it's been running Server since I purchased it.
I doubt the serial number is in use elsewhere: I purchased the 10-user version at a retail store in a sealed package and I've only installed it once.

System won't boot-no chime.

Despite repeated attempts and resetting the CUDA button, the system won't boot when start button is pressed. In the first few seconds it seems to make normal sounds; but no chime and settles into simply fan noise. This is true even if using C (with an Install CD). or Shift key. Is there anything else I can try? (I know it's actually a G3 B&W Motherboard; but I had nowhwere else to post it)

I do not remember exactly what was happening when it stopped. It may have been executing something , hung up, and wouldn't respond to the Command-Opt-Esc or I do remember one incident when it was booting up and stopped when it was partly thru "searching for local discs.
I checked the ref. article and tried to measure the voltages on the power connector. I was never quite sure what pin was what, since the colors did not jive with those in the article. At any rate 2 were approx. + 5 V (one was 4.85), the rest were essentially zero (I believe 1 or 2 were about 300 mv). I did notice that when the power connector is reconnected and start up is attempted, 3 little green lights come on on the motherboard. One goes off after a while.
I have tried the old Sonnet upgrade and have tried reseating all the RAM modules. All to no avail.
The Hard drive and all other parts seemed to be working fine prior to the failure.

System won't boot. INIT: No inittab file found Enter runlevel:

After the latest update that changed how intel ucode is updated, my system won't boot.
I think I missed a line when I edited "/etc/grub.d/10_linux" and ran grub-mkconfig -o /boot/grub/grub.cfg.
Any ideas on how to fix this?
I can't run grub-mkconfig from another machine, as it uses the live kernel info.
Any help would be greatly appreciated. Otherwise I'll have to reinstall

It seems to me that you've an old Arch version. inittab is deprecated AFAIK.
What is the Arch iso version?
That would probably be mid-2012 at the very latest I think as that's when I remember completely moving over to systemd...
@SyXbiT: Are you using the current Arch install ISO?

System won't boot up

Help please. I have a kt6 delta running an athlon 2700+ xp chip, 512 mb ddr 400.
When I set the fsb at the correct speed for the chip (166) the system won't boot hard drive led lights up constant. dvd drive and cd-r drive each run but the system won't boot. system seems to run fine at default and 133 mhz but the chip is incorrectly identified in windows (xp pro sp1) Any Ideas whats wrong?

Hi - I have the same board with the same processor, I have not problems rebooting after changing the bus speed. But I have had problems rebooting after adding in any card PCI or AGP. the system seems to have trouble clearing the Cmos, I would try clearing the CMOS with the JBAT. it doesn’t always seem to work but I have had some luck, though I have also pulled out the battery a couple of time too..
Good luck!

Upgrade from snow leopard 10.6.8 to montain lion on a iMac system won't boot getting a crossed out circle

Clean install OS.10.6.8 update it completly. May be you ignored some firmware update.
I have two incedents.
My thunderbolt port stopped working after upgrading to ML 10.8. I booted from external 10.6 , 10.7 still didnt work. Then i clean installed 10.6.8 and ran software update it updated the thunderbolt firmware and all is well now. This firmware update for some reason didnt show up in ML 10.8.
Secondly , when i upgraded my Brother's Macbook from 10.5 to 10.6.3 it would install but stuck with crossed out circle. Then i downgraded checked for update found an efi update , then the 10.6.3 worked fine.
