[linux-lvm] lvcreate seg faults in 1.0.1-r4

[linux-lvm] lvcreate seg faults in 1.0.1-r4

[Tim Nichols]

[-- Attachment #1: Type: text/plain, Size: 3045 bytes --]

I am having trouble getting lvcreate to work.  I've been able to create the PV and VG, but lvcreate always core dumps with a seg fault.   I've confirmed that I have the same code level in the kernel and tools (1.0.1-rc4).  I've tried compiling the tools with gcc (v2.96) and egcs (v2.91.66), but both fail.  I'm running a 2.4.14 kernel, lvm as a module, and glibc-2.2.4-19.  
  The problem seems to be with a corrupt lvol name from what I see in the gdb output I've attached.

 Any help would be great.

 Tim

try to compile the lvm userspace utilities without opimisation (-O0).

good luck

That seems to have solved the problem.  

 Thanks....

Re: [linux-lvm] lvcreate seg faults in 1.0.1-r4

[Francis SOUYRI]

  Hello Tim,

    You have a problem with gcc 2.96 (I have the same problem with a 
RedHat 7.2 gcc 2.96), Change in the file "<lvm_path_source>/make.tmpl" 
the line "CFLAGS+= -g -O2 -Wall -pg" by "CFLAGS+= -g -O0 -Wall -pg" and 
recompile the lvm utilities.

Best regards

Francis
