Topic: Tape backup ...... No space left on device

[vesnick]

Hi Guys,
I have placed this topic in the sme server 6 section as i feel it could relate to all SME versions.

I have got a 5.5 server  with a single 40gb hdd
running nonstop without errors from late 2002.

(ok I know 5.5..... i'll soon upgrade to 7 )

The server has an ADAPTEC  STD2401 20X40G SCSI tape backup
system and the tapes are dds4 20x40 tapes with a ADAPTEC ASC 29160KIT SCSI card.

SME User manager shows.

Currently your configuration and data files total approximately 24Gb.
Currently your hard disk  contains 31Gb of data.

flex Backups now have an error
----------------------------
DUMP: 80.10% done at 810 kB/s, finished in 2:00am
buffer (writer): write of data failed: No space left on device
bytes to write=10240, bytes written=-1, total written   13648040K
  DUMP: Broken pipe
  DUMP: The ENTIRE dump is aborted.
-----------------------------------------------------------------
Looks like the tape is full   "No space left on device" .  How can this be?
Is there something I've missed in the initial setup of the hardware back in 2002.....Help !!

regards
Nick

Higher compression will probably solve it.
Is full compression enabled?
In the hardware or the software?
See the tapedrive vendor for more info.

When it says 20/40 ... that is 20 gig uncompressed and 40 gig at best compressed.

You have to remember that files will not always compress that far ... especially if there zip files etc already.

My suggestion is get a bigger backup drive ... there really cheap on e-bay.

Looking at the stats you may also have a configuration problem ... 14gig written at 80% don't look right either.

But even so I would go for a bigger tape backup ... I'd say with that setup you would only get 25-30 gig backed up at very best.

The last time I used a tape drive under Linux (well, Xenix, really, back in 1988...) the dump command had an argument telling it the size of the tape (block size x number of blocks) - I kept having to modify systems for clients who upgraded from dc-300 tapes to dc-300xl tapes to tell "dump" to use the whole tape...

Was the STD2401 fully recognized when you installed it in 2002?  If so, did you have DDS4 tapes then, or is there any chance it was originally setup as a DDS3 12/24 tape drive?
