umount

[Mošnička Roman]

dd,
potrebuji udelat umount na jeden svazek, takze:

[root na lnx9hra root]# umount /dev/sda3
umount: /backupp: device is busy

hmm, zkusim 
[root na lnx9hra root]# fuser -v /backupp
                     USER        PID ACCESS COMMAND
/backupp             root     kernel mount  /backupp

nebo 
[root na lnx9hra root]# lsof |grep backupp

problem je, ze nevidim proc je toto zarizeni busy ...
Nemate nekdo nejaky napad ?

dik a s pozdravem Roman Mosnicka
