[flexbackup-help] extract Errors

[a s. <asy...@ho...>]

Hello,

I have been using flexbackup on multiple servers for a while. 
I have had trouble free running until recently setting up a new server.

Hardware:
Dell 2850 Dual processor, Raid 5 SCSI disk
Fedora 8
LTO2 Tape drive (Powervault 114T rack)
Tape connected direct to onboard SCSI channel.
(I have this setup working on a different server with the only difference being an LTO3 drive and an older version of Fedora)

The backups work without error with various combinations of buffer, blksize, mt_blksize, and pad_blocks.
Test-tape-drive also works without error for various combinations

With the extract command I am getting errors after 200-400MB of data has been extracted
Following  is the various errors changing the buffer flag:(errors are the same for different combinations of the blk flags which work)





Buffer = false 


dd: reading `/dev/nst0': Input/output error

3656+0 records in

3656+0 records out

239599616 bytes (240 MB) copied, 32.0883 s, 7.5 MB/s

dd: warning: invalid file offset after failed read

dd: warning: working around lseek kernel bug for file
(/dev/nst0)

  of mt_type=0x72 --
see <sys/mtio.h> for the list of types

dd: cannot work around kernel bug after all

dd: `/dev/nst0': cannot seek

dd: reading `/dev/nst0': Input/output error

3656+0 records in

3656+0 records out

239599616 bytes (240 MB) copied, 32.1839 s, 7.4 MB/s

dd: reading `/dev/nst0': Input/output error

3656+0 records in

3656+0 records out

239599616 bytes (240 MB) copied, 32.2825 s, 7.4 MB/s

(This cycles through a few times then copies another bunch of files then starts the cyclic error again)


Buffer = mbuffer



mbuffer: error: inputThread: error reading at offset
e480000: Input/output error



(fails after approx 420MB has been restored, flexbackup hangs)



Buffer = buffer



buffer (reader): failed to read input: Input/output error

afio: "-" [offset 216m+64k+0]: Fatal error:

afio: "-": Premature input EOF



gzip: stdin: unexpected end of file(exits gracefully)
Any help or suggestions would be most welcomeGav.
