Exactly. I need HA working solution for mounting file systems.
In example:
1 storeage with 1 lun
2 hosts.

lun i mounted (for example ext2/ext3 ) on host1.
When host one is down, i can mount this lun on host2.

I don't know how it is possible, because host1 and host2 sees this lun.

On this site i haven't found anthing on configuration based on EMC and linux.
Have got any experience ?

Thanks
