I had inparallel 10 set with flush-threshold-dumped and flush-threshold-scheduled 25.I received dump failed errors "no holding space" and device busy. > > Potential danger here in number of tapes available. > One run can use up to 10 tapes, one cycle up to 50 tapes, > yet you only have 15 tapes in use. > > Perhaps you don't expect to use 10/run, but even at 2 per run > you barely have enough for a single cycle.

As a final result on backup server there will be 2 NEO's with 4 LOT4 tape drives plus 1 single LTO4 drive. so this holding space will be divide for two main Backup sets and third with this single tapedrive. But now I just want to get it working reliably with one set because secon NEO is doing backup with our current backap server (netvault) +---------------------------------------------------------------------- |This was sent by [email protected] via Backup Central. |Forward SPAM to [email protected]. +----------------------------------------------------------------------
