 Typical problem with ufsdump backup on solaris 7
Hi All,

I am facing a typical problem with my backup on solaris 7 server.I
have a script which awk's the 6th field from the "df -k -F ufs" output
and puts it in a file and my loop takes the input from the file then
takes the backup using the ufsdump utilty.

I have 5 metadisk filesystems like /dev/md/dsk/d1, d2 , d3 ,d4 & d5. I
am able to backup from my script all the normal file systems and some
of the metadisk file systems except e.g d3 , d4 & d5.

When i am trying to backup these three file systems i get this error,

root@phoenix# ufsdump 0ucf /dev/rmt/0ubn /dev/md/dsk/d4
  DUMP: Unexpected condition detected: /dev/md/dsk/d4 is not a
character device
  DUMP: Cannot open dump device `/dev/md/dsk/d4': Not owner

I want to know why this typical behaviour is occuring which is doing
some metadisk file systems backup leaving some giving the above error.

Please anybody from the group could explian me this would be really

Thanks in Advance.

Are those 3 filesystems larger than the others?

Why are you grabbing the 6th field from 'df' (which should be the mount
point), when your command appears to be only using the first field?  

Anyway, you mount the block device (which appears in 'df'), but you need
to use the character device with ufsdump and fsck (which is what the
error message is telling you).

Either pass the mount point (like /data) or pass the character device
