[Linux-cluster] GFS Cluster + PowerPath ... fail ?



Hi everybody!!

First at all I want to give to thanks to the list "Linux-cluster" for the received aid and the information that contributes to me. Thanks!

Now, i have another small problem. I have a gfs cluster with three servers. Each servers has 2 hba ( Emulex LP9082 ) and use PowerpPath 3.0.5-032 for the path failover. Each hba "see" two luns, one for the gfs data an another for cluste quorum. I think that PowetPath is ok because if i do "powermt display dev=all" i see:

8< ------ 8< ------ 8< ------ 8< ------ 8< ------ 8<

Besides, i think that gfs cluster is well configured. I use GFS-6.0.2.27-0 and kernel 2.4.21-37.ELsmp over a RHEL 3.0 Update5.

The problem is that when i restar pool service i get the next message:


8< ------ 8< ------ 8< ------ 8< ------ 8< ------ 8<

Pool are configured over the logical lun (/dev/emcpowera1 for gfs data and /dev/emcpowerb1 for cluster quorum )

the 'fdisk -l' commands show the following:

my questions that make doubt me and clear the dream to me are:

What are the errors that take place when i reinitiating the pool service ? It is normal? ( i think not )
What are the errors than take place when i run the "pool_tool -s" commands ?
What is "Removing (8,65)" when i restart the pool service ?


Thanks in advance and sorry my poor English ( i use http://translate.google.com :-p )
