LTO4 - tape data extraction problem
Hi everybody -
**Full disclosure, I'm a Linux beginner**
I work in an environment where we receive data in different formats, extract it and then manipulate it. Often the data comes on hard drives - but yesterday we recieved a chunk of information on an LTO-4 tape and I'm having a difficult time getting it off.
We have a CENTOS machine connected to a LTO-4 tape drive. I put the tape in and used
mt -f /dev/nst0 rewind (the drive activity light lit up and the tape rewound, so I know the connection is good and NST0 is the correct drive designation)
To get data off I tried
tar -xvf /dev/nst0 which results in:
tar: /dev/nst0: Cannot read: Cannot allocate memory
tar: At beginning of tape, quitting now
tar: Error is not recoverable: exiting now
I tried manipulating the block size - tried
mt -f /dev/nst0 setblk 0
mt -f /dev/nst0 setblk 512
but I get the same error either way.
Would really appreciate any help in figuring out how to get this data off the tape!
thanks in advance,
