I updated scripts and manual for Oracle 10.2 @ OCFS && ASM @ SLES9 Sp3
(http://ftp.portera.com/Linux/);
important change rely to OCFSv2 timeouts (taken from
here -http://www.oracle.com/technology/pub/articles/hunter_rac10gr2_2.html#1
6 ). Problem is that OCFSv2 detects failure and panic if it cannot make IO
on the voting area of disk in 12 seconds, which is smaller than many IO
timeouts around (NetApp takes about 10 - 20 seconds to takeover, for
example).

Btw, I wonder, why SuSe don't change defaults for panic mode on servers - it
is obvious that servers should have defaults as

kernel.panic=1
kernel.panic_on_oops=1

(who need server which do not restart in case of panic?)

Timeout issue can explain few oops seen by OCFSv2 users (together with panic
settings).

PS. After all, it is all pretty stable on iSCSI. FC and Multipath is another
issue - require careful configuration (I was not able to configure it for
netApp FSP and old Qlogics 1Gbit HBA, and system freeze easily with and
without different 'oops').
