[PVFS-users] meta server and io servers out of sync

[Hale, Darrian J]

Thanks everyone for all your help, 

I just have one last question regarding: "Before you delete the meta file,
find its inode number".

Is the inode contained in the meta file? If so how do I find that out.  Or
do I want the inode number of the meta file itself?

I cannot get the inode number through the mounted filesystem, stat doesn't
think that file exists.

Thanks again, Darrian
