Yvan,

I see that you are running a TL2000 have you run the btape fill test on
your system. If you have did you get any errors?

I seem to be getting the following one.

05-May 15:17 btape: Fatal Error at dev.c:1705 because:
dev.c:1704 Attempt to WEOF on non-appendable Volume

Thanks
H

Subject: Re: [Bacula-users] Tape MTEOM error with Dell TL2000 (IBM
TS3100)

Hi,

thank you for the advices. We have very similar configurations, and I'm 
sure I'm not too far from the solution. I tried to use your settings in 
the storage daemon config file, and the "mt" options as well, than I 
didn't try so far.

But, as soon as I put those settings, I have another error

        Hardware End of Medium = No     # defaut is Yes
        Fast Forward Space File = No    # This line required if above

which is :
3-May 02:20 setmseblx0007-sd JobId 170: Error: Unable to position to end

of data on device "IBMLTO4" (/dev/nst0): ERR=dev.c:1354 ioctl MTFSF 
error on "IBMLTO4" (/dev/nst0). ERR=Input/output error.

Strange that it works for you then ... I issued all the "mt" commands 
you wrote. Tapeinfo gives me the samed infos as you have, but it's MTFSF

error or MTEOM ...

Yvan Broccard
  

I also had very similar problems when I first started testing Bacula.
    

Now,
  

I have both TS3100 & TS3200 models running without any issues on
RedHat 4 and 5 servers. My configurations are:

Autochanger {
        Name = TS3200_1_DRV1
        Device = LTO4_1
        Changer Device = /dev/sg7       # This is mapped to the
    

AutoLoader
  

        Changer Command = "/etc/bacula/config/mtx-changer %c %o %S %a
    

%d"
  

}

Device {
        Name = LTO4_1
        Drive Index = 0
        Media Type = LTO4
        Archive Device = /dev/nst0      # Device nstX created
automatically by st daemon.
        AutoChanger = yes
        AutomaticMount = yes;    # when device opened, read it
        AlwaysOpen = yes;          # Default value yes
        RemovableMedia = yes;
        RandomAccess = no;
        Requires Mount = no;
        Maximum Open Wait = 300         # Default value
        Maximum Rewind Wait = 300       # Default value
        Maximum Changer Wait = 120      # default is 120 secs
        Maximum Job Spool Size = 2G     # default is unlimited
        Spool Directory = "/export/shared/spool"
        Label Type = IBM
        Check Labels = yes
        LabelMedia = no;
        Hardware End of Medium = No     # defaut is Yes
        Fast Forward Space File = No    # This line required if above
HEOM is set to "No"
        BSF at EOM = no                 # Default is no
        Two EOF = no
        Volume Poll Interval = 300      # Poll the drive to seek the
    

status
  

}

I also changed the LTO4 tape drives' parameters with the "mt" command.

1. mt -f /dev/st0 stsetoptions
2. mt -f /dev/st0 compression
3. mt -f /dev/st0 stsetoptions buffer-writes
4. mt -f /dev/st0 stsetoptions async-write
5. mt -f /dev/st0 stsetoptions fast-eod
6. mt -f /dev/st0 stsetoptions two-fms
7. tapeinfo -f /dev/sg2
