The "/ dev/aacd0 on" & "on / var / ftp" parts make no sense to me. It should be: some_dev on some_dir (ufs, NFS exported, local, read-only) > > Launched with these parameters and this is what gives > > ftp # fsck -yf / dev/aacd0 > ** / Dev/aacd0 (NO WRITE) > ** Last Mounted on / var / ftp > ** Phase 1 - Check Blocks and Sizes > > As I understand it does not fix the fsck filesystem. > fsck filesystem_goes_here for example "fsck /dev/ada0s1a" or fsck mount_point_goes_here for example "fsck /" You are probably trying to fsck the wrong device... Rebooting to single user and fscking the RO mounted / fs works as usual. Please provide more info. HTH, Nikos
