[parisc-linux] LVM 1.0.1-rc4 on hppa

[joel.soete]

Hi all,

I just co the last cvs of kernel 2.4.9-pa42 and everything seems to work find as 
well as on model 712 as on model B180.

Then I try to have a look into LVM (last 1.0.1-rc4)on the B180:
no error at compile time neither for kernel neither for tools (just warning: 
pv_read_all_pv_of_vg.c:129: warning: deprecated use of label at end of compound 
statement)

Then I try first to do a 'pvcreate /dev/sdb' which failed:
vpcreate -- ERROR: "/etc/lvmtab" doesn't exist; please run vgscan

Also I excute 'vgscan':
Segmentation fault.

Here is my last kernel log:

looks like a null pointer dereference in a shared library -- can't tell
which without seeing the maps for vgscan.  i recommend running vgscan
under gdb and seeing wht's going on.

About gdb for hppa, may I use the one into 
"pehc /pub/parisc/binaries/debian/unofficial-debs/".

Yes.  I don't know what the current status is of getting an official gdb
for PA/Linux is... Matt?

Waiting for someone(Alan Modra?) to do a merge with upstream. Once that's done 
then the changes can be sent upstream as well as incorporated in the newly 
revived debian gdb package.

Alan's been too busy to do it but if there are any other gdb gods out there 
we'd love it if someone took this on.

The all LVM-HOWTO test seems to works fine if change -O2 to -O0 into make.tmpl.

I thinks so too.
I will try now to recompile with -O2 and -ggdb to try to have a better idea.

Thanks again for help,

ddd (as well gdb) failed on message:
0x4015dc88 in mocount () from /lib/libc.so.6

into call lvm_dont_interrupt (0);

which is a "simple loop on s" calling 'signal(s,SIG_IGN)' if s is not SIGKILL.

What could be broken?


Thanks again for help,

I also try to work with gdb and efence but it does not seems to work:
I re-link LVM (with -O2) tools with libefence then launch gdb.
At gdb prompt I type in "set environment LD_PRELOAD=libefence.so.0.0"
then "run".
But the message of the load of efence does not appears?
And run failled on Segmentation fault without any diagnostic of efence.
I think it is not the right way to work: if in command line I do "export
LD_PRELOAD=libefence.so.0.0" then launch "mkdir toto" the message of
efence load appears well?

Does it exist some where some HOWTO explaining the actual way to use
efence?

[parisc-linux] LVM-1.0.1 with kernel 2.4.16-pa16 (was: LVM 1.0.1-rc4 on hppa)

[joel.soete]

Hi all,

Just for information that this release compiles (now with -O0) fine with kernel
2.4.16-pa16 and also seems to works fine (at least on my b180.

Joel, please don't cc messages to both parisc-linux and sistina lists.
they have a bogus closed mailing list policy which means that people
replying to your email get annoying and offensive automatic emails.

lvm-1.0.1-rc4 (as well as lvm-1.0.1-rc2) works fine for me on various
2.4.9-paXX kernels including 2.4.9-pa42 (see below).

I guess :-) that you compiled the lvm-tools with optimization. Since 
there seems to be a general problem with the lvm-tools and gcc3 (appears 
also on other architectures (see lvm mailing list)) recompile the 
lvm-tools without optimisation or "weak" optimisation (-O0).

-O0 is no optimisation, -O1 is weak optimisation and -O2 is most
optimisations.  This is normally a bug in the code, not the compiler...
