Recently I wrote a filesystem under linux. I use read_inode2 to fetch inode staff(in the reiserfs way), and it is diskless(that means with MS_NODEV ops). When I want to export it using NFS, I found I should do following things: /* There are two requirements on a filesystem to be exportable. * 1: We must be able to identify the filesystem from a number. * either a device number (so FS_REQUIRES_DEV needed) * or an FSID number (so NFSEXP_FSID needed). * 2: We must be able to find an inode from a filehandle. * either using fh_to_dentry (prefered) * or using read_inode (the hack). */ for the first one, I should provide a FSID( I want to know where I can do it). for the second one, I use the preferred way(fh_to_dentry). Does that enough for me to export my filesystem by nfs?
