i have a reproducible segfault with vgscan.

i had pvmove'd several lv's. Then i rebooted. since then, vgscan
segfaults
the first 3 times  out of every 4 times i run it.

eg:

[root@rossi linux]# vgscan 
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "Main_VG"
Segmentation fault
[root@rossi linux]# vgscan 
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found inactive volume group "Main_VG"
Segmentation fault
[root@rossi linux]# vgscan 
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found inactive volume group "Main_VG"
Segmentation fault
[root@rossi linux]# vgscan 
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found inactive volume group "Main_VG"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: you may not have an actual VGDA backup of your
volume
group

this means i have to call vgscan 4 times in a row from my initscripts
before i can run vgchange.. :(

vgcfgrestore also has the same behaviour. :( segfault, segfault,
segfault, ok, segfault, segfault segfault ok.. etc..

System is 2.3.99-pre6-pre7.

I've looked at the BUGS page but i don't see this problem listed.

Further info available on request..

regards,

Paul Jakma.

Could you provide your VG configuration ("vgdisplay -v") and
a "vgscan -d" output to enable me to further dig into this one...

Thankd,
Heinz
