[opensuse] need debugging help (openSUSE LEAP)
Hi LEAP users, please could someone run these commands for me and send me the output? # as root! uname -mr modprobe -r scsi_debug modprobe scsi_debug dev_size_mb=100 sector_size=512 udevadm settle devname=$(grep --with-filename scsi_debug /sys/block/*/device/model | awk -F '/' '{print $4}') cat /sys/block/$devname/queue/{minimum_io_size,optimal_io_size} modprobe -r scsi_debug I want to compare the output of different kernel version 4.1.12, 4.1.13 and 4.1.15. Maybe there is a bug. So I'm specially interested in up-to-date and not-fully-updated Leap installations.

I ran this on TW even though you asked for Leap. I don't know if it will help or not, but I got: 512 64 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Uh, oh... I'm running a YOU while I typed the above, so I'm uncertain. The update is huge, by the way, I'm quite surprised. Biggest I have seen on a machine updated the previous week. I'll wait till I reboot the machine (it is a virtual one, vmplayer). Ok, rebooted, try again.

Quite different.
Thanks a lot Carlos and Malcolm! Seems that there is an issue from kernel 4.1.13 to 4.1.5. Looks strange that "optimum" is smaller than "minimum".
If you wish, I can try later on my laptop, before and after the update.
Maybe you can just reboot once again with old kernel to be 100% sure that it was the kernel update and not some of the other updates. FYI the original problem come from util-linux mailing list http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/11966 cu, Rudi -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ah. I failed to understand. Of course, doing it now.

There were a huge lot, perhaps the virtual machine was not current in updates previously. There were far less updates in the laptop.

I'm going to run the updates in the laptop, so I'll also take the chance to check your results. cer@Minas-Anor:~> su - Password: Minas-Anor:~ # uname -mr 4.1.13-5-default x86_64 Minas-Anor:~ # modprobe -r scsi_debug Minas-Anor:~ # modprobe scsi_debug dev_size_mb=100 sector_size=512 Minas-Anor:~ # udevadm settle Minas-Anor:~ # devname=$(grep --with-filename scsi_debug /sys/block/*/device/model | awk -F '/' '{print $4}') Minas-Anor:~ # cat /sys/block/$devname/queue/{minimum_io_size,optimal_io_size} 512 32768 Minas-Anor:~ # modprobe -r scsi_debug Minas-Anor:~ # After update and reboot: cer@Minas-Anor:~> su - Password: Minas-Anor:~ # uname -mr 4.1.15-8-default x86_64 Minas-Anor:~ # modprobe -r scsi_debug Minas-Anor:~ # modprobe scsi_debug dev_size_mb=100 sector_size=512 Minas-Anor:~ # udevadm settle Minas-Anor:~ # devname=$(grep --with-filename scsi_debug /sys/block/*/device/model | awk -F '/' '{print $4}') Minas-Anor:~ # cat /sys/block/$devname/queue/{minimum_io_size,optimal_io_size} 512 64 Minas-Anor:~ # modprobe -r scsi_debug Minas-Anor:~ # Same result as with virtual hardware.
