RMA for Sparc Solaris

[eviltommy69]

I'm testing the RMA for SPARC and I've found some issues already. First, the cpu.sh is using SAR, which doesn't run unless you setup your systems for performance statistics. I changed the script to use vmstat like the other Unix OS's, and it works great.

SunOS) vmstat 1 2 | tail -1 | awk '{print 100-$NF}';;

Also, I have some large UFS filesystems (connected to a Clariion) that are showing UNC percentages wrong. One of them indicates 189% available. It should be showing 12%. I have another indicating 49% available, when it should be 6%. How does the RMA calculate free space?

Thank you for correction

RMA for SunOs uses code like

Code: Select all

struct statvfs statbuf;
  if (statvfs(path, &statbuf)==0)
  {
     long int blocksize = (statbuf.f_frsize>0)?(statbuf.f_frsize):(statbuf.f_bsize);
     total = statbuf.f_blocks * blocksize;
     free  = statbuf.f_bfree  * blocksize;
     freeforuser = statbuf.f_bavail * blocksize;
     return True;
  }
  else return False;

total, free, freeforuser defined as "double" (because some C compilers does not support "long long" type)
How big is your filesystem?

The two filesystems are 24GB and 47GB.

What if you configure UNC test to show absolute size (Mg, Gb)? What values will be displayed by HostMonitor?

Filesystem#1 (24GB):
HM indicates 49% available, or 1831mb
SunOS indicates 6% available, or 1628mb

Filesystem#2 (48GB):
HM indicates 188% available, or 2470mb
SunOS indicates 22% available, or 10444mb

This is a Solaris 9 OS, and both of the filesystems are UFS.

Looks like problem in statbuf.f_frsize and statbuf.f_bsize variables.
Sun documentation doesn't really describe difference. RMA uses code that was recommended in several newsgroups, but how it should really work...
Could you provide telnet access to your system?

[eviltommy69]

Unfortunately, no...sorry.

[KS-Soft]

Probably we can make small test program to check what is going on...
Will you compile it?

Alex

[eviltommy69]

Yep, I can do that.

[KS-Soft]

Great, please give me some time to create that test program

Hi
I am really interested to know the outcome of this thread.
I just setup the RMA 0.80 for Solaris agent to run on my solaris 9 box. However hostmon is reporting different disk capacity results than the solaris.

Filesystem (8GB):
HM indicates 71% available, or 2851MB
SunOS indicates 86% available, or 6866MB

[KS-Soft]

I think we fixed that issue but we do not have SPARC system to recompile agent. Could you provide telnet/ftp access to some SPARC system?

Regards
Alex

Hi thanks for the prompt reply!

i'm very sorry but telnet/ftp access is not allowed. However , if u'd like me to compile the RMA code on the sparc server (or any code relating to this issue), i'd be more than willing. I've also sent an email to support@ks-soft.net about that possibility..

[KS-Soft]

Ok. I have sent source codes to your e-mail address.

I am having a similar problem where my disk space is reported wrongly. What was the solution ?
