General :: Hard Shutdown - Crashes - Partitions & HD ?
Sep 16, 2010
I've been running Debian Squeeze for the past couple of months. I decided to use a ReiserFS (not sure if it's relevant) and had a few problems where I had to hold the power button to shut down the computer. After that the system was not the same and froze from time to time (long periods of freezing) forcing me to hold the power button to shut down the computer, again.
Now, after /dev, /sbin...etc... not being found root not exiting, I have decided to do a new install, however, after several attempts at setting up new partition tables, deleting data on the HD and re-installing, I have failed. Maybe someone can give me some input... here are is my /var/log/syslog from when I ran the Debian install disk: pastebin - syslog - post number 1941832 (I think the end is most relevant).
In the mean time I am going to delete data on the current partitions (if I can) and try to re-install.

What I'm trying to do is to grant my regular user to locally mount partitions and shutdown the machine without a password. Here is what I've done to /etc/sudoers:
Code:
Host_Alias LOCAL = localhost
Cmnd_Alias SHUTDOWN = /sbin/shutdown
Cmnd_Alias MOUNT = /bin/mount, /bin/umount
<my_username> LOCAL=(root) NOPASSWD: SHUTDOWN, MOUNT
%wheel ALL=(ALL) ALL
My user is a member of wheel group and I want to type the password for each sudo command except for shutdown and mount. However I am asked for a password whenever I execute "sudo mount [...]" or "sudo shutdown [...]".

Right Now I'm using hdparm command in unix to shut down the hard disk but there are few issues with it.
when it wakes back up it consumes
lots power. Is there any other way
to do it?
Many times when I put my
hard disk to sleep, I can see few
bursts at the beginning and then
after a while it goes to sleep. I
think its because of the journaling
system in ubuntu (which I use) Have
anybody encountered that?
What would
be the best linux/unix operating
system (eg: ubuntu/centos/redhat) to
work on extensive hard disk
operations?

I want to make the transition from windows (sick of it). Im using Lenovo G530 Laptop and was wondering which would be the best Linux Os (meaning Ubuntu, fedora or something else). Keep in mind that I mostly use my laptop for college work and a lot of video and audio editing. I also want to be able to run Dual operating system (meaning that I wanna run both Linux and Windows) from the same computer as it might be easier for me to make the transition a little bit more easier. That being said I need someone to give me tutorials (video preferred) on how to make the partitions on the hard disk and step by step instruction on how to install both the two OS in my laptop.

I'm just curious - why do all linux distros (all I've seen) run their periodic disk checks during boot? I mean, I understand that a disk should be checked now and then, but why does the system do it during boot, when I'm waiting for it to load, instead of checking them during shutdown, when (most probably) user doesn't need the computer anymore.

I've been through a lot of the posts already, but nothing seems to solve my problem. I have Ubuntu 9.10 and Windows 7 dual installed (Windows was installed first). Everything has been working fine until a few weeks ago when I accidentally left a USB drive plugged in when I restarted my computer from Windows.
Ever since then, whenever I have restarted my computer from Windows grub2 has failed (it does not fail when I restart from Ubuntu). I get a varying message like Grub loading. The symbol ' ' not found. Aborted. Press any key..where the part between the single quotes is usually different each time. When this happens I have to reinstall Grub2 from a live disk, which is becoming a bit of a pain.
I've been reading around, but I don't really have a great understanding yet of how hard drives and partitions work in general, and so I haven't been able to work out what the source of this problem is.

My system sometimes crashes on startup/shutdown. No idea what causes it
This is my info:Kernel: Linux Mewtwo 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 07:54:58 UTC 2010 i686 i686 i386 GNU/LinuxUbuntu version: Ubuntu 11.04 (Note: This also happened BEFORE upgrading to 11.04)All the info i could get is in those pics (This happened on boot but I also have crashes on shutdown):[URL]I couldn't find those logs anywhere else in /var/log so I guess it happens before the log files are opened

I accidentally powered down in the middle of a session by removing the wrong battery from my laptop (a Motion Computing tablet), and ever since that happened knetworkmanager crashes with a segmentation fault on startup. I have uninstalled it and then reinstalled it from an openSuse 11.4 DVD I made a few months ago, but it still crashes on startup. Ifup says it connects to the wifi (Wayport Access @ McDonalds) I have available, but browsers don't reach the internet while Ifup is connected, so I can't sign on and get access to anything more recent. Is there some file I ought to delete,or some other software I ought to delete and reinstall?

I was stupidly compiling code on my netbook with 10% battery left. The CPU ate up my battery reeaally quickly and it did a hard shutdown while still compiling.When I boot up, the Ubuntu loading screen shows up for about two seconds and then it goes to a completely black unresponsive screen. I have a live install on my thumb drive, but I don't actually know what I need to do to fix whatever broke.Edit:Oo, something happened. When I pressed a key the screen filled up with a bunch of stuff I don't understand. But the last two messages are:
[ 450.807328] Fixing recursive fault but reboot is needed!mountall: Disconnected from Plymouth

I cannot locate shutdown log for Linux shutdown to check various activities carried out during shutdown. I can view Startup Log which is availble on console>Applications>System Tools>System Logs.
I have included Shutdown/Startup in dbora, so that Oracle 10gR2 Shutdown/Startup will be automated during OS Shutdown/Startup.
I want to check Shutdown log because Oracle Shutdown was not running, as from $ORACLE_HOME/shutdown.log contains no entries, where as startup log contains latest startup details.
That means here 2 issues are there. One, I want to locate OS Shutdown Log and the other being Why Oracle Shutdown not getting executed.

Basically, when I do a reboot or shutdown and then the system tries to start I get a blank screen thus I have to hit the reset button and then I'm showed a grub menu (not sure why I have it set to autoboot) and then I can boot properly.

So I recently got a WD MyPassport external hdd with 500gb capacity. I formatted it to NTFS so that it would be more efficient transferring data between my Ubuntu and Win7 dual boot. But now I want know if it is possible for me to create a 100gb FAT32 partition on the external without destroying the data on it.

Ubuntu 10.10 is dual booted but it is my primary OS.
Unfortunately it's on the outer edges of the disk in an extended partition.
This has always bugged me, with regards to read/write performance.
Do my concerns of reduced performance have any foundation? Should i bite the bullet and format the drive installing ubuntu first?
I ran the disk read benchmark and my read speeds were 100MB/Sec at the beginning of the test to just 55MB/Sec at the end. I have no idea if the position of the test has any bearing on the position of the disk or whether the speed recorded is affected by other factors such as the tests function or simulation.

Is there any way to Merge hard drive partitions? I didn't really know what I was doing during install and wound up leaving myself with over 100GB of unallocated hard drive space. if I create a new partition out of this, could I possibly merge it with another? and if I do, should I merge it with root or home? I am using 10.10, by the way.

I've been struggling with this one for a while - I have three SATA hard drives installed on my system:
/dev/sda - an 80 GB disk with three partitions, one NTFS for WinXP, one ext4 for Fedora 11 x86_64, and a boot partition
/dev/sdb - a 250 GB disk with one partition, ext4
/dev/sdc - a 250 GB disk with one partition, ntfs
I can mount any partition on /dev/sda without problems - everything works exactly as expected. Attempting to mount a partition from one of the other disks results in something like the following (this is for sdc1):
Code:
[User@machine ~]$ sudo mount -t ntfs /dev/sdc1 /mnt/shared
[sudo] password for User:

Especially /var because I am running a MYSQL server on this box. I want to know if there is a safe procedure to follow to move these partitions from the current sda2 and sda3 that they are now to sdb2 and sbd3 because this is a much bigger disk. I don't want to break MYSQL and I don't want to be down for a long period. I have heard of some people suggesting a sym link to a /newvar and /newuser on sdb but I have also read this will not work when moving to a different physical drive.

I've recently tried installing Fedora 14 on a HP z600 workstation, but I'm running into major stability issues.
I can successfully boot fedora 14 from the live-cd and can perform basic tasks from the terminal and within gnome. However, I sometimes experience hard-crashes when I am browsing the web with firefox. In fact, I can pretty consistently cause this by downloading a relatively large file (~100MB) with firefox. Interestingly though, I don't experience any problems when doing the same with curl.
Furthermore, I run into the same issues when I install fedora 14. Worse, the system seems corrupted when it recovers after rebooting... sometimes failing to make it to the login screen.
I'm suspicious of the network driver, but also of the memory. I have performed the memory test included on the live-cd, but it reports no issues. This may be so, but from previous experience with computers, I don't trust memory tests to detect all memory issues.
Ubuntu is similarly problematic; vista appears fine, with limited testing.
*Hard-crash: system locks up for 5 or so seconds, followed by a black screen, and then reboots. There are no error messages displayed.
EDIT: As a point of reference, Fedora 11 seems to be a stable for me.

Ok, this just started happening with ubuntu 9.10.
When it first happened, I didnt know what to do so i accessed all my data, backed it up in a diff partition, reformated my drives and reinstalled a clean 9.10. But now, every now and then (i think its when i use frostwire and have other programs running) my ubuntu keeps freezing up, it becomes non-responsive to anything i do, so i have to do a hard shutdown, after which, when i reboot, it is not able to mount /home, so i run FSCK and it fixes it, but ive done this about 3 times now, its starting to get a bit annoying, i dont know if anyone else has this problem, or if its a known bug. Here are my specs:
Running: Ubuntu Karmic 9.10 64 bit
3 Sata HDD: 1 TB, 750 GB, 350 GB
4GB Ram
2 Nvidia 7900GS
with a Pentium core 2 duo @ 3.0GHz

I got a new hard drive yesterday, a Seagate Baracuda XT 2000GB SATA3. I'm running it on the SATA3 jmicron chip in AHCI mode, and Opensuse 11.2 is having issues with using this hard drive properly.
The hard drive seems to take a while to detect, for one thing. After it is detected however, I am told I have no hard disk that can be used for installation. The exact message is:
"No hard disks were found for the installation. Please check your hardware!"
After that, I'm told the partitioner can't read the partitions on my hard drive properly:
"The partitioning on disk /dev/sda is not readable by the partitioning tool parted, which is used to change the partition table.
You can use the partitions on disk /dev/sda as they are. You can format them and assign mount points to them, but you cannot add, edit, resize, or rename partitions from that disk with this tool."
I partitioned the new hard drive under Windows, with a partitioning tool called Partition Wizard (free / home version). I'm not sure if hard drives partitioned with this tool are not recognized by OpenSuse's partitioner, or if it's something else.
I already installed Windows on this hard drive, so I can't delete all the partitions I have so far and start all over again (I'm keeping my system a dual-boot between Windows 7 and openSuse 11.2). What can I do so OpenSuse will see and modify my partitions? If it is the partitioning not being understood, is there some sort of tool that can make the partition table of the hard disk linux-readable? (a free Windows program that could do such).

I'm working with an older PC that belongs to my parents. They've been using Ubuntu 8.04 with no problems, and with 10.4s release, I planned to upgrade them to the newest version. The system's specs are as follows:
1.5ghz Athlon XP CPU
1.5gb RAM (PC 2700)
20gb hdd (IDE)
I have tried both the Ubuntu 9.10 (two different discs) and a 10.4 install CD and both give me the same issue. The installation proceeds along swimmingly until partitioning comes up. The partition table simply shows no hard drives. I have heard of this issue occurring with SATA drives and motherboard settings, but what could make it happen to an old IDE drive? Any odd-ball motherboard settings or anything that might need to be changed? GParted and the Live disc (along with the currently installed version of Ubuntu) recognize drives and can navigate them. What gives?

I have what seems to be a hard disk Write speed problems with my first hard drive. Timing the cp command of a 700 Meg file takes about 8 secs from disk 2 to 3 but takes 25 minutes from disk 2 to disk 1.
Here are the details:
Kubuntu 9.04 (Kernel 2.6.28-15-generic)
Hard Disk 1 : /dev/sda (WDC WD2500KS-00MJB0)
Partitioned
/dev/sda1 ext3 / 10 Gigs
/dev/sda2 extended 222 Gigs
/dev/sda5 linux-swap 2 Gigs
/dev/sda6 ext /home 220 Gigs
Hard Disk 2 : /dev/sdb (WDC WD2500AAKS-00F0A0)
Partitioned :
/dev/sdb1 ntfs 16 gigs
/dev/sdb2 xfs /home/eric/data_drive 216 Gigs
Hard Disk 2 : /dev/sdc (ST3500320AS)
Partitioned:
/dev/sdc1 xfs /home/eric/data_drive2 465 Gigs
By doing 'time cp ...sdb1/test.avi ...sdc1' takes about 8 seconds and same vice-versa. the command 'time cp ...sdb1/test.avi ...sdb1/test1.avi takes about 11 seconds and the same holds true if sdc1 is used But copy sdb1 or sdc1/test.avi to either sda1 or sda6 and it takes 25 minutes. Same problem if I copy from the same drive partition (sda). I have booted a livecd Knoppix 6.2 and the same problems happens.. So safe to say it's not Kubuntu. The only thing that is left to do is backup and reformat the partitions as XFS and try again. I also did a full smartcontrol Extended test and no errors. Checked all the various logs and nothing found.

I just bought a new 2 TB hard disk to replace my old 175 gig one. I currently am dual-booting Lucid Lynx and Windows 7, and rather than go through the process of reinstalling both, then reinstalling all my programs, settings, and everything, I was wondering if there's a way I can just copy the partitions on my 175 GB disk to the new one, grow them to fill up the rest of the free space on the new 2 TB disk, and then plug that HD into the primary master plug on my motherboard... will that work?

I'm trying to install Ubuntu 10.10 64-bit on my laptop HP pavilion 3046ee . When I reach the partition part , it doesn't detect the Windows 7 os , and doesn't detect any hard disk partitions ( it sees the whole hard disk as one unallocated partition ). I faced the same problem when I tried Ubuntu 10.04 LTS.
