Hi, all. I managed to get my changer working with Amanda using chg-scsi. Today I started the first test dump to see what would happen.
Using hardware compression, my DLT-IV tapes hold about 70 GB. I set up a dump of several large and small partitions totalling ~88 GB. One was not mounted for the dump so the total was actually 73 GB. I set runtapes to 2 in the amanda.conf file thinking this would tell amanda to use two tapes, but I see this in the amdump log: [snip] INITIAL SCHEDULE (size 73008621): gorge /export/home pri 11747 lev 0 size 16340165 gorge /usr/xxxx pri 11747 lev 0 size 15425329 gorge /usr/oracle2 pri 11747 lev 0 size 12874971 gorge /usr/oracle pri 11747 lev 0 size 7166160 gorge /usr/oracle5 pri 11747 lev 0 size 4502198 gorge /usr/oracle3 pri 11747 lev 0 size 4348242 gorge /usr/oracle4 pri 11747 lev 0 size 4143069 gorge / pri 11747 lev 0 size 3541838 gorge /public pri 11747 lev 0 size 982111 gorge /var pri 11747 lev 0 size 818101 gorge /export/gorge pri 11746 lev 0 size 2865347 gorge /export/mada/yoga pri 11746 lev 0 size 40 DELAYING DUMPS IF NEEDED, total_size 73008621, tape length 69029888 mark 43 planner: FAILED gorge /export/gorge 20020226 0 [dumps too big, but cannot incremental dump new disk] planner: FAILED gorge /var 20020226 0 [dumps too big, but cannot incremental dump new disk] planner: FAILED gorge /public 20020226 0 [dumps too big, but cannot incremental dump new disk] delay: Total size now 68342837. [snip] -------- So it dropped some small partitions until it got to a total it likes. I thought, however, that runtapes tells Amanda to use the changer to fill additional tapes as needed. Am I assuming the wrong thing? Does runtapes mean something else? I have included some snips from my configs. Please shed some light on this if you can.
