Re: How do I make every node have direct access to the file system?

hi!

thirst of all i must thank you all for your postings.

let's begin from the start:

i have a running master node with 2 partitions

/dev/sda1 mounted as /boot
/dev/sda2 mounted as /

let's forget about swap partition for now

there are howtos for mirroring /dev/sda2 with the help of drbd to another
node

if the master node goes done then the other takes over, as far as i
understood the whole thing.
i havent had time yet to play with the drbd solution.

but what happends if the second node goes also down?
the cluster becomes unavailable.

so we thought of using a nfs share instead of /dev/sda2

so the master node boots up and instead of using /dev/sda2 as / filesystem
it uses a
nfs share. the next node boots from it's hard disk, finds the masternode an
continues as usual

we tought of using openfiler as nfs server, because openfiler includes also
failover to a second
openfiler installation.

the goal is, that every node can become a failover node, not even only two
nodes which are mirrored via drbd.

i think due to my bad english, that there were some missunderstandings
regarding the access to the filesystem. i hope i cleared it out a little bit
now.

greets
