Hi,
here is the configuration file.
Yesterday I blanked 2 tapes, and assignated one to a pool "Daily" and
one to the pool "Weekly". I ran btape fill and test with successs.
I then started full backup jobs of 12Gb in loop. Got that result:
Job A Daily, EOD 12GB ok
Job B Weekly, EOD 12GB ok
Job A Daily, EOD 24GB ok
Job B Weekly, EOD 24GB ok
Job A Daily, EOD 36GB ok
Job B Weekly, EOD 36GB ok
Job A Daily, Starting, unloading tape from JOB B and i got the "MTEOM"
error at this point. (Could not append to end of data)
08-May 09:16 setmseblx0007-sd JobId 181: 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.
This morning I updated the status of that volume from the console,
putting it to append again, and the job started and finished successfully !
There is a "sleep 60" after the load in my mtx-changer script, and a
"sleep 180" after the unload. Should be enough no ? when I do it
manually with "mtx" it takes something like 15 seconds.
Now the 4th "Job B" sent me the MTEOM error as well at the same position
on the tape.
Here is the configuration file :
Device {
Name = IBMLTO4
Media Type = LTO4
Device Type = tape
Archive Device = /dev/nst0
Autochanger = yes
#Changer Device = /dev/sg3
#Alert Command = "sh -c 'tapeinfo -f %c | grep -i tapealert'"
Label Type = IBM
Check Labels = yes
LabelMedia = No;
Random Access = No;
RandomAccess = No; # which one is the correct
syntax ?
AutomaticMount = yes; # when device opened, read it
RemovableMedia = yes;
AlwaysOpen = yes
Requires Mount = no;
#Maximum Job Spool Size = 2G # default is unlimited
#Spool Directory = "/export/shared/spool"
# things to try:
TWO EOF = No # tried but append test fails. default is No
#Offline On Unmount = no # default is No
Hardware End of Medium = no # default is Yes
BSF at EOM = No; # default is No
#Backward Space Record = no # default is Yes for
tape device
#Backward Space File = no #
# Use MTIOCGET = Yes # only need to no on
some ***BSD systems
Fast Forward Space File = no # tried, not better, got
MTFSF error
# This line required if above HEOM is
set to "No"
Volume Poll Interval = 300 # Poll the drive to seek the status
}
Autochanger {
Name = TL2000
Device = IBMLTO4
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg3 # already set in the device resource. both
are possibles
}
Thank you all for your help !
