Title:
Laggy & Finally Completely Frozen 12.04.2 on Large cp or rsync
Status in “linux” package in Ubuntu:
Expired
Bug description:
I have two pairs of raided disks. I am trying to copy 1/2 T of data
from one to the other. First I tried "cp /from /to". It seemed to
behave ok, so I left it overnight. When I came back in the AM, the
machine was completely frozen. I had to use the power switch. Only
about 150GB had been copied. I tried again with "nice -n 10 cp ..."
and the same thing happened. Then I discovered ionice and shifted to
rsync. So I used "ionize -n 7 rsync -cva /from /to". I also turned
off the sleep/lock for the display. Again it seemed to behave ok, so
I left it while I went for dinner. Two-three hours later, I found
that all windows were frozen. I couldn't use REISUB, the reset switch
_or_ the power switch. I had to power off using the switch on the
power supply. Rebooting, I found that about 300G had been copied by
this point. I am trying for the 4th time now, again using rsync.
iotop is running. It regularly freezes between rsync's copying one
file and the next. If I try to shift to a window or type at the
terminal, there is a freeze until the file being copied by rsync is
finished. If I keep typing at the terminal (or in the text-box in
Firefox, as I am now) then things become smooth until I stop for a
bit. Then the freezing begins to happen again. (That's not
completely true. Tab completion at the terminal is a disaster. Cut &
paste in this window is the same.) It may be my fantasy, but it seems
that if I keep using the machine, getting it to respond to
keyboard/mouse intput, then it doesn't permanently freeze up. It's
when I leave to it's own devices for some time that I have a problem.
The only difference between the last try and the first 3, is that
after having a look at dmesg, I enabled IOMMU in the BIOS. Probably
irrelevant, but I did also notice the "spurious 8259A interrupt: IRQ7"
message in dmesg that has been reported in bug #75626.
I haven't changed anyting with the I/O scheduler, which has been
reported as causing I/O problems in bug# 427210 and #131094. So, it
still reads: "noop [deadline] cfq"
Tyan S3970 with 2 CPU's (8 cores).
Two pairs of WD drives (500G & 2T)
TARO add-on storage card (used by the 2T drives)
Ubuntu 12.04.3 fully updated.
Essentially new install (During this process I only added iotop, atop, htop,
acpi, m5deep & emacs)
500G drives are RAID-1; 2T drives are RAID-1 & encrypted.
