    unknown ZFS error freezes System

    I have a system connected to a zfs pool comprised of 2 drives. The OS is installed in an 8 Gb USB Stick.

    Right now, I am copying a lot of data (1.5 Tb ) made of various big documents (700Mb-10Gb) from a Nas in my 10/100 Ethernet network over to my ZFS array.

    Over the course of 24 hours, I found the system frozen 3 times ( With Frozen I mean that even moving the mouse would not move the cursor, and any keyboard command would not do anything. Even pushing the power button, that should make a window pop up, made nothing). Every time this happened the system was copying some files in the zfs array.

    Every time I found the system frozen, I also found the 2 HD spun down and completely silent.

    That made me think that the source of the error could be zfs.

    Apparently, in the log, there are few message until a precise time, when the error occurred, after wich no more messages are logged (until reboot).

    If you could help me, I would be really glad.

    System Info:
    Asus E35M1-i deluxe ( AMD E350 APU motherboard)
    4Gb ram
    OS installed on a USB stick.
    2X2Tb Western Digital Caviar Green EAX (connected to sata ports 1-2)

    Software: Ubuntu 11.04 (Updated)
    ZFS kernel module installed from official repository (zfsonlinux.com)
    Transmission client downloading data to the zfs disk is also running

    ZFS:
    There is no RaidZ on the pool. It's just a pool created with
    "sudo zpool create tank "device1" "device2"

    Re: unknown ZFS error freezes System

    It now froze again. I found it once again completely frozen with Hard Drives Spun Down.

    This time the system log hints at some problems with the wireless network ( I am connected via ethernet, but there is also a wifi network around, to wich he has a stored password).

    If anyone could help, I would appreciate.

    Re: unknown ZFS error freezes System

    Hi, I have the same problem, but not only zfs is hanging. Have a ubuntu 11.10 64 bit server Linux 3.0.0-17-server x86_64, connected to some iscsi lefthand storages with some zpools.

    Even a kill -9 does not help.

    Have you tried raising skinny elephants? It might let you shut the system down cleanly next time this occurs.
