I did not get your question clearly - if FS = filesystem, then how it is spanning several drives ? Are you using RAID ?

The c0t2 its backup on tape DDS-4(without trouble), but when i want backup the c0t0 on a tape DDS-3 with the command tar
does display "error EOF" (the information is <24GB!!!!!!!)so i did use the command ufsdump, displaying the next message:

how can its possible use two tapes if the information is less than 24GB!!!
is something wrong with the information or with the disk??
Thanks. Greetings Marcos
ufsdump works with single file system i.e. it's not possible to use ufsdump only to backup several file systems.
ufsdump will work on RAID volumes, as they are one file system ( hardware layer, several harddrives are irrelevant in that case, as this works transparently )
