It seems to me you're trying to access a normal filesystem (like ext4) 
from many clients at the same time?

It won't work, and you'll severely corrupt your filesystem by doing that.

If you really, really know what you're doing (seems you don't!), i.e. 
other clients are accessing the target readonly (note - the target, not 
mounting the filesystem readonly - this may still cause writes, i.e. 
journal reply, and corrupt the fs), you may "see" the files by syncing 
data on the initiator which made the write (or, possibly mounting the fs 
"sync").
