Re: [Bacula-users] Bacula stalls after 2.5 TB

I have a job running right now.  It seems to be in the "stalled" state.  

status storage

Device "Drive-1" (/dev/nst1) is mounted with:
    Volume:      037178L4
    Pool:        Default
    Media type:  LTO-4
    Slot 49 is loaded in drive 0.
    Total Bytes=1,354,752 Blocks=20 Bytes/block=67,737
    Positioned at File=0 Block=21

status client

Shows no data counter changes.

   Backup Job started: 02-Dec-10 09:32
    Files=1,215 Bytes=1,040,342,163,456 Bytes/sec=39,869,018 Errors=0
    Files Examined=1,215
    Processing file: /firewall/mysql/archive/sdw_sw/sw_20090916.tar
    SDReadSeqNo=5 fd=5

Though bytes/s is going down

The file does not seem to be open so I am at a loss of what is going on with 
some of these files.

Are you sure it really stops? How long did you wait?

repeat the "status dir" command a fw times. Are any of the counters
(Files, Bytes, Files Examined) and the file name changing?

What does "status storage" report?

Can you see or hear if the tape drive is active?

What does a "ls -l /firewall/mysql/archive/sdw_netflow/netflow_20100430.tar"
on that system show?  Is there any chance that this is a sparse file
with (big) holes (eventually even unintentionally, like after some
error in a RAID)?

Best regards,

Wolfgang Denk
