[Orca-users] Re: Orcallator on Solaris 10

Should have done more research before last night to list on segmentation 
error for orcallator... but here is more info now.

It looks like I did have problems in March 2005 on this server with 
orcallator getting segmentation errors.  I even wrote the list on this 
thinking it was caused by Veritas 4.1 install.  After complete erase of 
all my disk paths through reboot, it appeared to solve the issue and 
orcallator was working again.

I saw a few comments about MAX_RAWDISKS and USE_RAWDISK in the 
orcallator.se file as resolution to my issues.  There is no rawdisk 
reference in the version I have (r497 and r412) so that does not appear to 
be at issue.

Although I'm still not sure how, I am thinking that my disk paths coming 
and going is the culprit here.  We do a lot of moving around of volumes 
via snapshots and clones, so disk that appear today may not appear ever 
again.

Does anyone else do a lot of diskpath altering on their systems?  Do you 
have problems?

I did a "-d DWATCH_OS" option on the se run and got the following tail 
before is does a segmentation fault:

break;
return sderr(STRUCTURE);
count++;
ld = readdir(dirp<18446744071543194240>)
if (count<27> == GLOBAL_diskinfo_size<150>)
dp = *((dirent_t *) ld<18446744071543217808>)
if (dp.d_name<c3t61d91s1> == <.> || dp.d_name<c3t61d91s1> == <..>)
if (!(dp.d_name<c3t61d91s1> =~ <s0$>))
ld = readdir(dirp<18446744071543194240>)

dp = *((dirent_t *) ld<18446744071543217904>)
Segmentation Fault


I'm think I may need to rebuilt the paths again, but certainly would like 
to find a non-reboot option to this.

I may also alter orcallator.se to completly eliminate gathering disk info, 
since load/cpu/network/etc would be better than nothing.

Thanks,
Liston
