[Bug 504113] Re: udev delays mounting USB devices during heavy I/O
Similar Test case: I copyed a big (3.8GB) file to an USB-Stick. During that i started "sudo udevadm -e" and plugged in a 2nd USB-Stick The copy process took ~8 minutes. The 2nd USB-Stick did not mount. Not during copyprocess and not after. Log is attached. The first entry in the log is when I plugged in the 2nd USB-Stick. (1st Stick Manufacturer: Corsair, 2nd: Trek) ** Attachment added: "udevadm-e.txt" http://launchpadlibrarian.net/39221556/udevadm-e.txt -- udev delays mounting USB devices during heavy I/O https://bugs.launchpad.net/bugs/504113 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The output from sudo udevadm -e is attached. I ran udevadm while copying to a slow USB device, and there was the usual delay during mounting - I've marked where it happened in the file (after seqnum 2147). ** Attachment added: "udevadm-2" http://launchpadlibrarian.net/39215259/udevadm-2 -- udev delays mounting USB devices during heavy I/O https://bugs.launchpad.net/bugs/504113 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 504113] Re: udev delays mounting USB devices during heavy I/O
Please run "sudo udevadm monitor -e" in a terminal, then plug in your USB key. You should see two groups of output, copy and paste this into the bug report.

[Bug 504113] Re: udev delays mounting USB devices during heavy I/O
the /dev/sdx1 messages appear immediately. So I think udev is OK. The next "higher" Step of mounting is devicekit-disk. I think the bug is there. Please take a look at the duplicate Bug.

[Bug 504113] Re: udev delays mounting USB devices during heavy I/O
Some extra info: I reproduced this bug just now and tried mounting the just-inserted external USB key manually with: sudo mkdir foldername sudo mount /dev/sdg1 foldername but the mount command returned the error 'special device /dev/sdg1 does not exist'. The syslog showed that /dev/sdg1 had already been recognised by the system, however. -- udev delays mounting USB devices during heavy I/O https://bugs.launchpad.net/bugs/504113 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 504113] Re: udev delays mounting USB devices during heavy I/O
Correct, it isn't installed. I think I read that Karmic uses udev instead of hal for auto-mounting, so perhaps that's why g-v-m isn't installed. I've changed the bug description to udev in case it's more accurate. ** Summary changed: - gnome-volume-manager delays mounting USB devices during heavy I/O + udev delays mounting USB devices during heavy I/O ** Description changed: - Binary package hint: gnome-volume-manager + Binary package hint: udev, nautilus To reproduce: - 1. Insert a (slow) usb key and let g-v-m automount it. + 1. Insert a (slow) usb key and let nautilus automount it. 2. Start copying a large file to this usb key, eg 700 MB. 3. While the copy is underway, insert another USB key. - g-v-m either mounts the second usb key when the file copy finishes, or - doesn't mount it at all. + nautilus either mounts the second usb key when the file copy finishes, + or doesn't mount it at all. The attached syslog shows the latter event (ie the second USB never gets mounted - it didn't even appear in nautilus's Places sidebar to let me manually mount it). It also shows /bin/sync being blocked, which might be relevant. This happens in Ubuntu 9.04 and 9.10. I'm using the 2.6.32.2 kernel, but it also happens with the stock 2.6.31 kernel.
