Forget strace. I have come across programs/device drivers that will stop
working once you remove print{f|k}s added for debugging! Various delays can
make a program work well. Is your program using a device driver you know
might be faulty? Try GDB, my friend.

Or in so called 'user-space' sys 2m35.222s Time the kernel spent on the program, trying to do I/O, for example Thanks for the answer.? If my script takes 162m total time, out of which computing time is 58m and IO operation in 2m.? Then what might be the reasons that takes remaining 102m of my script time??

Re: [Ilugc] tape drive configuration
Thanks for your reply. It seems that the BIOS is not supporting this device . You might need to flash/upgrade the BIOS / some configuration needs to be done in the BIOS. Check with the H/W vendor. Checked with the Hardware Vendor. That will not do any harm to the access of device they said. Error is only related to bootable state of that SCSI device. MPT Rom boot tries to boot from the device. But there is no bootable meduim or device is found. So its giving this error.

Although most of the time the target Flash is pretty restrictive, I usually have a separate, full fledged target filesystem with GDB et al, mounted over NFS. And when you have a filesystem with all the tools you need, you development time comes down unbelievably. My second preference would be to use gdb-server on the target and gdb itself on a less restrictive host. Regards, -- Shuveb Hussain B I N A R Y K A R M A Chennai, India.

Balu manyam wrote: i already used fdisk - deleted partition 2 - re-added the same with bigger size - and then saved with 'w' - i got the message that the kernel will obey the new part table from the next reboot - but that does not seem to be true - as it did not happen even after the reboot - I still see the old partition table Fdisk is not the right tool for it. It only changes the partition.. doesn't change the file system.. you will require a utility that can also dela with filesystem. Parted fits in well for your requirement. I havent tried using it before.. Was always lucky to have data on a LVM :). The man page says it is possible to extend space without destroying data.. My suggestion is to back-up data before trying this.. I haven tried it myself But in ur case you have already changed the partition.. so i am not sure how this will work.. best way would be to re-create the same partition with fdisk.. then use parted. how r u checking your filesystem size? df? df displays size based on fs properties.. so even if you have a larger partition without extending the filesystem.. that would be the case... to confirm check the /proc/ info for exact kernel status of the disks... i think i should be able to boot the machine off a CD and do this - but just curious if one can do this from a running OS and reboot if need be Partprobe should force your kernel to read your partition table without re-booting.. Never edit partitions for file systems which are already mounted. if normal data partitons no re-boot would be required.. if any of the system partitions are used, you will require rescue CD.
