I use a ZFS array for backups. The data is first copied to this array, and later copied to tape. This post contains some information which might be useful should I need to replace one of the drives in the array. We have 10 HDD in this system. Two are used in a gmirror for […]

Today is the first Sunday since I started using a scratch pool with Bacula. I was disappointed to see an email asking for a tape to be mounted. Why? With four tapes in the scratch pool, I shouldn’t be asked for a tape. Something is wrong. But there is no directive on a pool to

I recently wrote about copying jobs with a very good backup tool. My goal was to keep copies of the backups on both disk and tape. Since then, I started playing around with a little webpage to keep tabs on what’s in my tape libary. Today I noticed a little problem. I have backups from 75 days ago that are waiting to be copied to tape.
I’ll just let you think about why this happened. Yesterday, this queue held jobs that were about 16 hours old. How did this old job get into the queue?

Here I go, removing an old ZFS dataset that is no longer required. But first, some stats (which have been edited to remove non-zfs output): [dan@kraken:~] $ df -h Filesystem Size Used Avail Capacity Mounted on storage 1.4T 15G 1.4T 1% /storage storage/bacula.DO.NOT.USE 5.8T 4.4T 1.4T 76% /storage/bacula.DO.NOT.USE storage/compressed 1.4T 49K 1.4T 0% /storage/compressed storage/compressed/bacula
I have an improvement on the original query. This one outputs ‘nil’ if the volume is empty. bacula=# SELECT mediaid, volumename, volstatus, slot, inchanger, pool.name, CASE WHEN volbytes < = 64512 THEN 'nil' else pg_size_pretty(volbytes) END FROM media, pool WHERE media.poolid = pool.poolid AND volumename LIKE 'ETU0%' AND inchanger != 0 ORDER BY slot; mediaid

I pretty much ignore my tape library. It asks for tapes when it runs out. However, I think I should be looking ahead and anticipating requests. Thus, I came up with this SQL query: [dan@ngaio:~] $ psql bacula psql (8.4.5) Type “help” for help. bacula=# SELECT mediaid, volumename, volstatus, slot, inchanger, pool.name, volbytes FROM media,

Earlier today, I noticed the following output from a Bacula job: 24-Sep 14:14 bacula-dir JobId 38548: Start Backup JobId 38548, Job=latens_home.2010-09-24_14.12.38_31 24-Sep 14:14 bacula-dir JobId 38548: Using Device “MegaFile-latens” 24-Sep 14:09 latens-fd JobId 38548: DIR and FD clocks differ by -307 seconds, FD automatically compensating. That’s 5 minutes. It shouldn’t be varying by that much.
