Hi There,

I am trying to create file system on a software raid5 device but after while it hangs on:

Writing superblocks and filesystem accounting information:

i have tried with mkfs.ext4, and mke2fs as well but the result was the same.
any ideas what could be wrong ?

"iostat -x 5", check if there is activity going on. Start it before you do 
the mkfs to make sure nothing is going on (for instance a resync) before 
you start creating the filesystem.

A large filesystem with ext3/ext4 takes quite a while to create. How long 
did you wait until you decided it was "hung" ?
