Summary: RAID 1 with 600 targets/RAID 5 with 50 targets causes OOM with
320MB of RAM, and I don't know why.
First off, thanks for everyone's hard work on this lovely piece of
software. It's very nice to be able to mess around with things at this
level without having to delve into kernel space, and being able to
manipulate things with command lines and libraries :-)
I've been trying some experiments recently, mainly as a precursor to
some ideas I had, and I've run into some issues with device-mapper.
Specifically, my use of *lots* of targets, and the tendancy of the
kernel to head into OOM territory when you try this. I've been using a
2.6.22 kernel (with Ubuntu's basic patches, but I don't think that's
what's causing this) under a VMware virtual machine with 320MB RAM, and
it seems to be having some issues. It's got a default text-mode Ubuntu
7.04 setup, with probably a few more things loaded than it really needs,
but not that much.
With RAID 1 targets, I can get up to about 600 targets before the whole
thing seems to lock hard (dmsetup itself gets OOM'ed, and I can't get
back to the shell or to any other of the virtual terminals). While
scaling up to that point, I find that for every RAID 1 target,
device-mapper seems to eat ~.5MB of RAM. The targets themselves are
currently very small (1MB I think) as this was more a test in many
targets, rather than in large targets.
I was also interested in the RAID 5 patch, so I'd earlier tried a kernel
with the 20070720 version of the patch (marked as 2.6.22-rc7, but it
applied cleanly against the aforementioned 2.6.22 kernel, and it was the
latest version available when I was downloading). OOM also occurred, but
at only ~50 targets. In this case, there's a substantial delay between
telling dm-setup to load the target and OOM (dmesg post-mortem says ~50
seconds), and the shell is still responsive, so I could get a dmesg log
(attached).
I've also attached the genlist.py that I hacked together for generating
many targets, as well as the 100 item "test" target file I started with
for RAID 5 before narrowing the problem down to ~50. genlist should be
fairly self-explanatory (command line for the example test file was
"python genlist.py -l 100 sda sdb sdc")
Any thoughts on what's causing this, and anything that can be done to
reduce/remove the problem? I'm guessing this isn't a usual target
configuration, as most people with 50 RAID 5 targets probably have GBs
of RAM...
I can reproduce all of this easily, so if there's any further questions
about my configuration or recommendations for things to upgrade, I'd
love to hear them!
Thanks,
Tom Parker
