Sharing SAN disk with multiple severs
Hi ,
I had a requirement to share a san disk between two rhel severs. I am planning to discover the same disk in two rhel nodes and mount it. Is it a feasible solution? and what kind of issues we may encounter mounting same disk in two OS's parallel ?

Hi All,
I have mirrored SAN volume on my B80 rootvg. Can I just remove the mirror and "Remove a P V from a V G" and it will be a diskless AIX?
Is that going to boot on SAN rootvg volume?
Thanks in advance,

Hi all,
My main function is as a DBA. Another person manages the server and the SAN.
I just want to know if I should be worried about high disk I/O or is it irrelevant as the I/O "load balancing" will be "taken care" of by the SAN?
For example, I have hdisk1-5 and I can see that there are... (2 Replies)

KFS(4) Kernel Interfaces Manual KFS(4)
NAME
kfs - disk file system
SYNOPSIS
disk/kfs [ -rc ] [ -b n ] [ -f file ] [ -n name ] [ -s ]
DESCRIPTION
Kfs is a local user-level file server for a Plan 9 terminal with a disk. It maintains a hierarchical Plan 9 file system on the disk and
offers 9P (see intro(5)) access to it. Kfs begins by checking the file system for consistency, rebuilding the free list, and placing a
file descriptor in /srv/name, where name is the service name (default kfs). If the file system is inconsistent, the user is asked for per-
mission to ream (q.v.) the disk. The file system is not checked if it is reamed.
The options are
b n If the file system is reamed, use n byte blocks. Larger blocks make the file system faster and less space efficient. 1024 and 4096
are good choices. N must be a multiple of 512.
c Do not check the file system.
f file Use file as the disk. The default is /dev/sd0fs.
n name Use kfs.name as the name of the service.
r Ream the file system, erasing all of the old data and adding all blocks to the free list.
s Post file descriptor zero in /srv/service and read and write protocol messages on file descriptor one.
EXAMPLES
Create a file system with service name kfs.local and mount it on /n/kfs.
% kfs -rb4096 -nlocal
% mount -c /srv/kfs.local /n/kfs
FILES
/dev/sd0fs
Default file holding blocks.
