Once a while, during boot, Debian forces checking of hard disks. I understand that's a wise thing to do. However, I wonder what you could do to abort such process and postpone it to next boot (let's suppose you are in a hurry and you have switched on your computer only for a quick glimpse to a document).
View 14 Repliesunclean shutdowns/reboots. Whenever I boot/restart, I notice the message "/dev/hdb1 (and hdb2) was not cleanly unmounted, check forced." Then fsck(?) scans them without errors, and everything continues normally. FWIW, hdb1 @ hdb2 are ext2, /boot & /tmp respectively, whereas all other partitions are ext3. Could that (ext2) be why? I checked halt, reboot, umountfs, umountnfs.sh, and umountroot in /etc/init.d, and nothing jumped out at me, though I'm not exactly sure what I'm looking at/for.

I recently installed Lenny 5.0.3 i386 onto an old HP XE783 box. I've got a couple of errors that pop up on boot, and I'm not sure how to troubleshoot them. A couple of the lines from /var/dmesg that strike me:weird, boot CPU (#0) not listedby the BIOS. ACPI Error (dsopcode-0595): Field [ALB2] at 120 exceeds Buffer [CRSA] size 104 (bits) [20080321] {along with two other ACPI Errors (psparse-0530): Method parse/execution failed; and (uteval-0233): Method execution failed.}.Error: Driver 'pcspkr' is already registered, aborting.
The most annoying thing (I think) has to do with the ACPI errors: the box won't power down after issuing a shutdown command; it bumps into single user mode then prompts for the root PW.
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'm having some issues creating output from kdump-tools. (Initially to diagnose some system freezes when using wine, but now I can't a staged panic to work and provide proper output.)
I initially started following what is stated at this link: https://www.bentasker.co.uk/documentati ... ian-jessie
Where basically the author says:
Code: Select allapt-get install kdump-tools crash kexec-tools makedumpfile `uname -r`-dbg
to get all relevant tools.
Then in /etc/default/kdump-tools edit the following to :
Code: Select allUSE_KDUMP=1
in /etc/default/grub I edit the following line to the following :
Code: Select allGRUB_CMDLINE_LINUX_DEFAULT="quiet crashkernel=128M"
followed by update-grub. Then I get the pleasure of rebooting.
once I'm back in my system, I do the following.
Code: Select allecho 1 > /proc/sys/kernel/sysrq
echo c > /proc/sysrq-trigger
The system freezes, but does not dump any relevant information or reboot. It just hangs.
I have recently updated my GNOME installation from 3.x to 3.14. Suddenly, there are many glitches. The power buttons on the power menu does nothing, I am forced to shut down via the terminal, everything goes black every now and again, and there is a weird colour pattern behind some icons when I hover over them. But most importantly, the icons and text do not show up on the "Activities -> Show Applications -> All" menu. They still there, as you can see the opening animation before they disappear, and I can click on them, but you just can't see them. The "Frequent" menu works fine. Here is a YouTube video I have made to explain my problem.

I did change the icons, but this was after these problems started happening, and so it should be un-related.
I am new to Debian but not Linux-based systems. I have been experimenting a lot with Debian Lenny/Squeeze. I am growing more comfortable each day with the Debian design. Yet there remain many unexplored areas. I am creating a migration check list. Things to check, prepare, or reconfigure when moving from one Linux-based system to Debian.
I have a good computer background and my current check list probably is fairly good. Yet I would appreciate input and opinions from experienced Debian users of things to watch in such a migration. Login defs, passwd/group files, different directory locations, keymaps, services and daemons, etc. I am not too concerned with the desktop as I plan to stick with KDE 3.5 for a while and I can basically move those settings across.
I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?

aborting...
From a persistent live USB Mint 10 Gnome 32 bit.
When booting, the grub menu appears and allows me to boot from the internal hard disk (sda) any OS there, such as WHEEZY (sda9). On the external disk (sdb) there is a dd'd copy (not an installation) of SQUEEZE (sdb1), which at one time was on sda but which has different partition assigments listed in its grub.cfg than the current ones shown below for sda.
Code:
Select allNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 111.8G 0 disk
├─sda1 8:1 0 23G 0 part
├─sda3 8:3 0 1K 0 part
├─sda5 8:5 0 3.9G 0 part [SWAP]
├─sda6 8:6 0 11.7G 0 part
├─sda7 8:7 0 19.5G 0 part /home/norman/data
[code]....
Can I manually boot the SQUEEZE copy on sdb1 using grub commands (set, linux, initrd, boot) without disturbing the WHEEZY and other OSs on sda? Or will they be disrupted?Alternatively if for example JESSIE is installed in sdb3, for example, can it be booted similarly without affecting the installations on sda? I hesitate to try this by trial and error because of the work and time involved in rebuilding messed-up OSs to their desired configurations.

View 3 Replies View RelatedI have written a demon/service listening to a socket to accept and process connecting clients. I've modelled the service on the multi-threaded example given by [url].
The service seems to work correctly, processing clients then at what appears to be random points, it will terminate and I don't seem to get any error messages or information.
I'm executing the demon script by using another script, attempting to catch any output.
Both scripts are attached.

Now..: Booting Debian Unstable from USB or CD-ROM, then start installer. Tell it to install on second samsung S-ATA disk.

Or will the installer understand, and see the windows7 installation and add it to Grub?
If not, what should I do inside /boot/grub/menu.lst when Debian is up and running?
During installation when i set the partitions i have to provide a Name and a Label. What is the difference of these? It looks like only one should be needed. Any problems of using the same name for both?

I didn't have my ethernet connected and ended up only getting a pretty minimal desktop with not much installed besides Gnome. This bothered me, as I thought I could install the whole desktop off the CD. I reinstalled, this time with my Ethernet connected. This time it took much more time and gave me what I wanted, a complete desktop. Simply put, what do I need to install everything that I currently have without having my Ethernet plugged in?

I'm trying to do some RAID managing with mdadm. I would like to sync my spare disk and then remove it from the array for making a backup out of it with dd command (the best way i can think of to get the current image of the whole system as it can't be done using the active RAID as source, because is constantly in use and changing). So, I have RAID1 array with 1 spare and 2 active disks (configuration listed below). Now I would like to force spare to sync and then remove it from array, although not faulty.
However, mdadm man page states:
"Devices can only be removed from an array if they are not in active use. i.e. that must be spares or failed devices. To remove an active device, it must be marked as faulty first."
So, I'd have to mark a disk as faulty (which it is not) to be able to remove it from array. There seems to be several people reporting that they can't remove this faulty flag accidentally given to a drive. And mdadm does not give direct for such operation. Isn't there a way I could remove and add disks whenever feeling like it?? One way would be open the cover and physically remove the disk. I'm not taking the risk, though. System is almost always in use, so there is not much chance for me to power off for temporary disk removal.
RAID CONFIGURATION:
~# mdadm --detail /dev/md0

Version : 00.90.03

I have never seen this one before (see below) - note how /dev/sda1 is mounted from the first disk listed by fdisk, but /dev/sda2 comes from the second disk; what is going on here? This is what I did: I installed the latest debian "Testing", which went well - it found the disks in the order show by fdisk -l here. When it booted up after installation, it failed because it couldn't find /, which I repaired by editing the grub menu (I told it to start from the other disk), and it came up. But now I had to mount /u01 by hand from /dev/sda1; strange. I suppose I could just go and change the physical disks around, but I'd like to understand this. Any ideas?

The package manager seemed to hang when downloading a small update for YAST itself (related to ncurses, I think) so I hit the abort button. The package manager quit but now it doesn't work. Trying to start the software management module (Qt version) give me the following error:
UI Syntax Error
Couldn't load plug-in qt-pkg
Check the log file!
So I then tried the console version of YAST. The software management module doesn't work here either. It give me the following error:
UI Syntax Error
Couldn't load plug-in ncurses_pkg
Check the log file!
I Googled a bit and came to the conclusion that for the second error I should try the following command:
zypper install yast2-ncurses-pkg
But this just gives me another error:
zypper: error while loading shared libraries: libzypp.so.619: cannot open shared object file: No such file or directory
So now it appears that both YAST and zypper are corrupt!
I have a system running CentOS 5.5 (194.32 Kernel) that has been working fine for about 8 months. I found it stuck one morning dumping a Soft Lockup Kernel message every 10 seconds and have been trying to find out what is going on - here is what I've done and found.
System is a Core i3 with 4Gb DDR3 ram and 2 1.5Tb SATA drives - everything is less then 1 year old with not too much load (this is a backup system for my server - a twin and the other works fine)
Intel Mobo: DM55HC
Rebooting the system (after doing a fsck on the drives with lots of errors) it runs for about 20 hours or so and then drops back into this problem.
Prior to going into the soft lockup it reports that the Journal has aborted on one drive or the other and drops into a Read Only FS.
There is nothing in the logs apart from the aborting journal message and the soft-lockup)
Tried fsck with badblocks check on the 2 mountpoints for both drives (dunno how to check the swap partition) - nothing I could see there.
I have tried memtest for about 36hours. No errors
I ran smartctl long tests on both drives. No Errors
Installing two scsi hard disks on a debian system.
It is a physical old HP machine (netserver lc2000) with a fresh debian wheezy 7.0.8 installed.
