XenでBacula用のDomain-U作って運用してる。
気づいたらそのハードディスクイメージの使用率が100%になっててBaculaが止まってた。
Xenだから別にいいやと思って、ハードディスクをシステム用とデータ用で分けてなかった。
ちょっと前にISOを展開してHTTP経由で見れるようにしたのが原因。
今回はそのディレクトリをバックアップから除外して、ラベルを作り直して復旧させた。
本体は全然止まらないのに、バックアップがよく死ぬ。
Xenはよく止まる。
困ったもんだ。
Webから見れるようにしようと思ってから半年が経った。

ラベル削除
*delete
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
In general it is not a good idea to delete either a
Pool or a Volume since they may contain data.
You have the following choices:
1: volume
2: pool
3: jobid
Choose catalog item to delete (1-3): 1
Automatically selected Pool: Default
+---------+------------+-----------+---------+-----------------+----------+--------------+---------+------+-----------+-----------+---------------------+
| MediaId | VolumeName | VolStatus | Enabled | VolBytes | VolFiles | VolRetention | Recycle | Slot | InChanger | MediaType | LastWritten |
+---------+------------+-----------+---------+-----------------+----------+--------------+---------+------+-----------+-----------+---------------------+
| 1 | eth0 | Error | 1 | 257,482,597,491 | 59 | 5,184,000 | 1 | 0 | 1 | File | 2010-01-28 02:07:58 |
+---------+------------+-----------+---------+-----------------+----------+--------------+---------+------+-----------+-----------+---------------------+
Enter MediaId or Volume name: eth0
This command will delete volume eth0
and all Jobs saved on that volume from the Catalog
Are you sure you want to delete this Volume? (yes/no): y
bacula-dir.confに除外リストを追加
FileSet {
Exclude {
# 除外するディレクトリのフルパスを追加
}
}
リロード
service bacula-dir restart
