reiser4 and 2.5.60

reiser4 and 2.5.60

[Ookhoi]

Hi Oleg,

I builded a kernel with these options, like you told in your other mail
(which I lost, hence this new mail).

CONFIG_REISER4_FS=y
CONFIG_REISER4_CHECK=y
CONFIG_REISER4_DEBUG=y
CONFIG_REISER4_DEBUG_MODIFY=y
CONFIG_REISER4_DEBUG_MEMCPY=y
CONFIG_REISER4_DEBUG_NODE=y
CONFIG_REISER4_ZERO_NEW_NODE=y
CONFIG_REISER4_TRACE=y
CONFIG_REISER4_DEBUG_OUTPUT=y
CONFIG_REISERFS_FS=y

And disabled CONFIG_PREEMPT.

I still get a Segmentation fault when I want to untar a kernel source on
a fresh 512MB loop filesystem.

Does this help you?

Kind of.
It seems that inode_file_plugin(inode)->key_by_inode pointer is zero for one of inodes.
But I do not see how that can happen at all.
I personally untarred (and then compiled) kernel on this reiser4 snapshot without any
problems more than once (in fact this is on of my basic tests). I tried bot UP and SMP,
block device and loop device with file.  Can you describe your system in more details?

Bye,
    Oleg

Sure. It is a P-MMX, 200MHz, with 512MB ram, and a 4GB scsi disk.

OS is up to date (every day, or at least before each compile) Debian Sid.

As said before, I do reiser4 on a loop fs. I did the same with reiser3,
and that worked ok. Could the loop fs be a problem for reiser4?

I attach dmesg, cpuinfo, lspci and .config

Do you need more info, or want me to test things?
It seems that reiser4 in BK is not updated for a few days now.

Hm. That must be real slow, is it? (just because not all of the RAM is covered
by L2 cache, I mean. Or do you have some sensible chipset in there?).

Well, it should not, but if you can test it not on loop device just to
be sure, that would be nice.

I need to experiment a bit more locallywith info I got from you, I think.

It is slow, but I am not aware of issues with too little L2 cache. A
quick look at dmesg didn't give me more clue. Can you please explain a
bit, or give some google keywords?

It is only 200MHz, so I expect it to be slow, but if I can make it
faster that would be nice (without removing the ram if possible ;-)

I see if I can free a partition, or put an extra disk in.

Goody :-)  Well, let me know if you want me to test something. I'll let
you know what happens with reiser4 on a partition.

Well, some common chipsets of that time could only cache limited amounts of RAM
(64Mb for TX or VX chipsets, 256Mb for some other chipsets I dont remember about).
Accesses to RAM regions that are not cached are awfully slow.
But these accesses are still faster than hitting HDD ;)
So the "slram" driver was developed that allowed to use
non-cached memory as a RAM-disk for swap usage.

There is some sensible (from a quick look) article at
http://www.computerwriter.com/archives/1998/cw050798.htm

Well, try to remove the ram, first to make it to be only 256M then
64M and see if the system becomes faster at trivial non-memory hungry
stuff.
If this is indeed the case, consider changing motherboard/increasing L2
cache size (hard to do nowadays, when you cannot buy even P3 equipment
easily ;) ).
Nothing else comes to mind.

I can boot it with mem=64M. And try to unzip something large a few
times.

Owh, never mind, I'll save some money for a new one ..

That also gives me a Segmentation fault when I want to untar the kernel
source.

I did mkfs.reiser4 on a 2.2GB partition, mounted it, cd'ed into it, and
untarred the source (it is not zipped).

After this oops, another came when I did dmesg. It is below this one.

(mkfs.reiser4 is 0.3.0)

Hope this helps!
