Solaris delete file no free space

[Jagriti]

Hello good morning

I have a sun Solaris server,lately i discovered that my server lacks free space,so am wondering to control how many space is free on a tape and how I can delete a single file on a tape.

any thoughts
helps is really appreciated...

/dev/rmt/* are the actual devices.
The asterisk mean different for example "n" = no rewind.
mt -f /dev/rmt/0 status brings the status of the first tape drive

To read the contents of a tape
tar tvf /dev/rmt/0

To write to tape
tar cvf /dev/rmt/0 /dir/to/backup

To extract the contents of the tape
tar xvf /dev/rmt/0

Inode which results even if you delete the files from a filesystem, inodes do get cleared, they can still hold that address space.
may be you can run sync command 3 times.
on the other hand check fuser -cu <filesystem name>
it can bring you the users accessing the filesystem.

Delete and free space means the presence of some sort of file system to collate sectors,tapes don't bother with since they seek so slowly... Instead they'd be used as one big file,which keeps an archive. but if your tape's one of them from the obviously no data better go ahead with the program that have made the tape data, not the tape itself.
