bug report

[Howard Shane]

Hi,

Your warning displayed when starting reiserfsck recommended a bug report 
when the program exits with an error or fails. I have a Maxtor 60 gb 
drive that I have had problems with for the last couple of days. Upon 
accessing a certain directory, whatever program I'm using (ls, file 
manager, dump) freezes, at which point I can't access anything on the 
mountpoint.  I get the following error on running reiserfsck (debian 
reiserfsprogs 3.6.4):

    reiserfsck --check started at Mon Dec  2 13:22:46 2002
    ###########
    Replaying journal..
    0 transactions replayed
    Checking internal tree../ 86 (of  88)/ 23 (of 170)
    The problem has occurred looks like a hardware problem.
    Check your hard drive for badblocks.

    bread: Cannot read the block (22148).

When trying --rebuild-tree:

    reiserfsck --rebuild-tree started at Mon Dec  2 13:28:59 2002
    ###########

    Pass 0:
    Loading on-disk bitmap .. ok, 4893046 blocks marked used

4873744, 5323 /sec

...at which point reiserfsck freezes completely. I have already backed 
up the data on this disk, so I don't need any support, and since it 
looks like a hardware problem I will try reformatting the disk next. 
Hope this info is of some help.

PS, I have used ext2, ext3 and xfs and think that Reiserfs is by far the 
best high performance filesystem out there. Keep up the great work.

Hi all,

Was just wondering about the possibilities of using reiserfs on my
Solaris 6 machine.

Any chance of that?

I am having problems with FS performance (large number, 20K of small
files in folder with constant writes and deletes) on the Sun Machine and
was thinking if this can help me.

The only way I know is to use a Linux machine running reiser and NFS it
over. But performance will surely be degraded this way....any other
suggestions?

If you can convice SUN to pay for the porting of reiserfs to SUN
then it is possible.
Alternativey you can follow htp://namesys.com/support.html instructions.

Linux is able to run on SUN boxes too, and reiserfs is available for
Linux on any supported hardware if it is littleendian or bigendian.

Switch the OS, switch the OS and the hardware or pay for the porting.
(This is assuming that you did all the necessary tuning of your solaris box
already).

Bye,

Almost none.  Unless you're clued enough about Solaris kernel internals to
port a filesystem, in which case you'd not be asking.

You might want to look into whether Solaris 7, 8, or 9 address your
performance concerns - Solaris 6 is quite ancient.

I doubt it.  I can't imagine Sun (or anyone else) paying Hans enough money to 
do this.

Veritas VXFS is good for this type of thing.  Any time you want half decent IO 
performance on Solaris you want Veritas VXFS and Volume Manager.

In 1999 I was doing some work on AIX machines.  I found that an AIX server was 
so slow that NFS mounting a ReiserFS file system over a 10baseT network was 
faster for some operations!!!  If you do a usenet search you can find 
references to this, comp.sys.aix or something.

Another option is to use Linux on the SPARC machine.  Linux on SPARC reputedly 
performs a lot better than Solaris if you have 8 or less CPUs, even without 
the ReiserFS issue.  I think that Linux on SPARC can even run Solaris 
binaries (but I'm not certain).


PS  There is no such thing as Solaris 6.  They jumped straight from Solaris 
2.6 (which is presumably what you are using) to Solaris 7.0.

It is not so far fetched....   There are big customers of theirs like 
United Airlines that want reiserfs, and they did meet with me, they just 
didn't act....  Pressure them, they are very influenceable over there in 
marketing....

Now, if we could just get reiserfs for OS X!  It would be so nice to have a 
firewire device which could work on linux and OS X.  Just missing a common 
FS.

Who should we bug to get this happening? Apple?

Any opinions on the new journalling HFS+ filesystem that was added in 10.2.2

Funny you should mention that.....

I gave them a 5.5 hour reiser4 presentation last month.  I don't know 
yet if they will buy a reiser4 port (I hope so, it would be a lot of fun 
to work with them, they aren't afraid to innovate....), but they did 
make pretty darn sure they understood reiser4....  

I bcc'd Dominic (the guy they hired from BeFS) just in case he finds 
this thread interesting....;-)

BeFS also pushes the envelope, so working with them could be rather 
interesting I think.
