[Linux-cluster] Using Ext3 On External Storage

[Manish Kathuria]

What are the pros and cons of using ext3 filesystem on shared external
storage partitions when each of the partitions is going to be mounted
on only one node at a time ?

There is a two node active-active cluster running different services
under normal scenario one node mounting two partitions from the shared
external storage and the other node mounting another two partitions
from the shared storage. When one of the node goes down, the floating
IP address, the mounted partitions and the service on the failing node
will be transferred to the other node. At any point of time, each of
the partitions will be accessed by only one node. In this scenario,
What are the drawbacks or risks involved if the external shared
storage partitions are formatted with ext3 instead of GFS ?

Thanks,
