Hi all,
Due to a certain app requeriments, I need to share an iscsi lun
between two sl5.x and five sl6.x servers. This lun is formatted with
ext4 fileysytem (I have used one of the sl5.x servers to do this). Can I
expect some type of problems ???
You need to reconsider the filesystem type for a shared LUN. Even if only one
server at a time mounts this filesystem, using a clustered filesystem will
prevent some of the problems you might experience.
See https://secure.wikimedia.org/wikipedia/en/wiki/Shared_disk_file_system for
a list of filesystems providing this functionality; upstream's GFS is
available, as far as I know, in both 5.x and 6.x and may be a good choice for
what you're wanting to do.
GFS2 was my first option, but due to changes on gfs code between version
released by upstream on RHEL5.x and RHEl6.x, I have discarded ...
I don't need a cluster filesystem, because only one server at the same
time needs to mount this filesystem ...
