running bacula 2.0.3 with mysql 4.1.13 on SuSE 10.0; ADIC scalar-100 with 4 LTO-1 drives
Hello, I am still having a problem with concurrent jobs. Bacula is unnecessarily changing tapes and tapedrives. Basically i want to backup three different server every night and i want to use one drive for each server to speed up the process. So i use the following configuration: - Max concurrent jobs set to more than 3 - Different pools for each server - One job for each server - Distributed start times (Job1 at 22:05, Job2 at 22:10, Job3 at 22:15) to ensure that the drives are always requested in the same order. But bacula does strange things: Day1: Job 1 using Tape 1 in Drive 1 Job 2 using Tape 2 in Drive 2 Job 3 usnig Tape 3 in Drive 3 Day2: Job 1 using Tape 1 in Drive 1 Job 2 using Tape 4 in Drive 3 Job 3 using Tape 3 in Drive 2 Day3: Job 1 using Tape 1 in Drive 1 Job 2 using Tape 2 in Drive 2 Job 3 using Tape 3 in Drive 3 Day 4: like Day 2 Day 5: like Day 3 On Day 2, Job 2 does not use the already mounted tape 2 in drive 2 but instead gets an appendable tape from the pool and puts it in the next "free" drive (drive 1 is used by job 1, drive 2 is blocked by tape 2 which job 2 doesn't want to use) previously unmounting tape 3. So job 3 has to reinsert tape 3 into drive 2, because the drives 1 and 3 are in use. The main question is, why doesn't bacula use tape 2 for job 2? It is not full or otherwise unusable because it will be used the very next day. The job and pool configurations are the same for all servers and job 1 is working like expected (always using the same drive and tape). Anyone any idea what's going wrong?
