General :: Ubuntu: Tool For Displaying Disk Activity In General And By Process?
Oct 12, 2010My Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

Software :: Which Value Is For Highest Priority For Real-time Processes
Dec 18, 2009I want to set my program with highest priority for real-time processes. I understand the priority for real-time processes ranges from 1-99, but I get completely confused after reading Understanding the Linux Kernel and the manual of sched_get_priority_max(): which value has higher priority? either 1 or 99. Understanding the Linux Kernel says 1 has highest priority but sched_get_priority_max() returns 99 for SCHED_FIFO and SCHED_RR policy.

Programming :: Process Does Not Write To Disk While On Background
May 18, 2011I am doing a program that reads data from a gps and some other devices and writes some files with all the information. When I run it normally it works fine, but if I run the program in the background (with the ampersand) files are not created until I bring it to foreground or close it. I am confused, the program should run the same way with and without the ampersand. (Could it be that the main process that creates all the threads does not create them when it is executed in background? It seems like if the program is stopped until I take it to the foreground).

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.
General :: Process Scheduler A Part Of Process Queue?
Aug 12, 2010as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.

View 1 Replies View RelatedGeneral :: Windows 7 Disk Management Utility Doesn't Show Disk With Ext3 Partition
Oct 10, 2010I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?
Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.
General :: Migrated From Ext3-disk To A Ext4 Disk - Warning: Unable To Open An Initial Console
Feb 4, 2010OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev
chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda
ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?
