Hithere,
I compiled bacula-1.38.2 last week and I running btape to test my LTO
drives.
We have two HP Ultrium drives, which are part of a HP C7200/dell pv128
autochanger. I am currently testing the drives separately. Both drives
pass the "btape test" command. Both drives fail when using "btape fill
simple".
For Drive-1,btape fills ~2GB then aborts. I guess the last block is
never written properly. The fill test continues though, it thinks it
has filled the tape and attempts read the last block, where it hangs.
So...
Suggestions for troubleshooting ?
Any magic mt commands I should be issuing before starting the test ?
Thanks,
Chris
Here is my bacula-sd.conf:
Device {
Name = Drive-1 #
Drive Index = 0
Media Type = LTO-1
Archive Device = /dev/nst0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = no;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes;
LabelMedia = yes;
# Enable the Alert command only if you have the mtx package loaded
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
# SpoolDirectory=/.tape_spool
# Maximum Spool Size = 20G
# Maximum Open Wait = 30 seconds
}
Device {
Name = Drive-2 #
Drive Index = 1
Media Type = LTO-1
Archive Device = /dev/nst1
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = no;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
LabelMedia = yes;
# Enable the Alert command only if you have the mtx package loaded
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
# SpoolDirectory=/.tape_spool
# Maximum Spool Size = 20G
# Maximum Open Wait = 30 seconds
}
Here is the output for "btape fill simple:"
> ./btape -v -d 100 /dev/nst0
*fill
This command simulates Bacula writing to a tape.
It requires either one or two blank tapes, which it
will label and write.
If you have an autochanger configured, it will use
the tapes that are in slots 1 and 2, otherwise, you will
be prompted to insert the tapes when necessary.
It will print a status approximately
every 322 MB, and write an EOF every 3.2 GB. If you have
selected the simple test option, after writing the first tape
it will rewind it and re-read the last block written.
If you have selected the multiple tape test, when the first tape
fills, it will ask for a second, and after writing a few more
blocks, it will stop. Then it will begin re-reading the
two tapes.
This may take a long time -- hours! ...
Do you want to run the simplified test (s) with one tape
or the complete multiple tape (m) test: (s/m) s
Simple test (single tape) selected.
