I've a two node linux cluster. Need to share 1 HD to
read/write simultaneously, from either box. Should
either fail, I need the other to keep functioning.
I created 1 lvm on each server (changed lvm.conf as
per instructions). Did gfs_mkfs -- no errors. Ran
this (on each server)
> ccsd
> cman_tool join
> fence_tool join
> clvmd
> vgchange -aly
> mount -t gfs /dev/gfs_vg/lvol0 /data
No problem. Now, when I create a file on each server,
it doesn't appear on the other. What's the deal?
(this is my cluster.conf:)
