1.1ceph数据迁移&&bacula配置调整

为了规避因单个OSD利用率达90%而导致整个集群错误无法访问，ceph集群现已在原ceph块设备的基础上建立了cephfs文件系统用于存储数据，需要把原备份到块设备上的设备迁移到新建的cephfs上，迁移完毕后把ceph rbd回收，后续所有的备份数据直接写到cephfs。

• rbd分配的指定空间满了之后需要新创建，cephpfs的空间可以横向扩容，也可以避免单个OSD引起集群故障

1.2在备份服务器的ceph-client上mount cephfs文件系统

• T机房（1xx.xxx.xxx.x3）：ceph-fuse -m 1x.xxx.xx.x9:6789 -r /tt_bacula /cephfs/
• Y机房（1x.xxx.xx.x1）：ceph-fuse -m 1x.xxx.xx.51:6789 /cephfs/

1.2.1迁移数据

• T：/data1/d0*/下的数全部数据迁移到/cephfs/tt/backup_d0*/
• Y：/data1/d0*/下的数全部数据迁移到/cephfs/yz/backup_d0*/
  特别注意：在做数据恢复的时候需要把数据还原到原/data1/backup_disk0*/下才能恢复数据

1.2.2 调整bacula-sd配置

1.2.2.1T机房

bacula-sd.conf中添加7个Device F8/9/10/11/12/13/14分别指向/cephfs/tt/下的7个目录
bacula-sd.conf新加配置如下：

Autochanger {Name = F8Device = F8-Dev1, F8-Dev2Changer Command = ""Changer Device = /dev/null
}
Device {Name = F-Dev1Media Type = File8Archive Device = /cephfs/tt/backup_d3/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10
}
Device {Name = F8-Dev2Media Type = File8Archive Device = /cephfs/tt/backup_d3/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10

}
Device {Name = F9-Dev1Media Type = File9Archive Device = /cephfs/tt/backup_d1/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10
}

}
Device {Name = F10-Dev1Media Type = File10Archive Device = /cephfs/tt/backup_d2/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10

}Autochanger {Name = F11Device = F11-Dev1, F11-Dev2Changer Command = ""Changer Device = /dev/null
}
Device {Name = F11-Dev1Media Type = File11Archive Device = /cephfs/tt/backup_d4/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10
}
Device {Name = F11-Dev2Media Type = File11Archive Device = /cephfs/tt/backup_d4/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10
}Autochanger {Name = F12Device = F12-Dev1, F12-Dev2Changer Command = ""Changer Device = /dev/null
}
Device {Name = F12-Dev1Media Type = File12Archive Device = /cephfs/tt/backup_d5/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10
}
Device {Name = F12-Dev2Media Type = File12Archive Device = /cephfs/tt/backup_d5/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10
}Autochanger {Name = F13Device = F13-Dev1, F13-Dev2Changer Command = ""Changer Device = /dev/null
}
Device {Name = F13-Dev1Media Type = File13Archive Device = /cephfs/tt/backup_d6/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10
}
Device {Name = F13-Dev2Media Type = File13Archive Device = /cephfs/tt/backup_d6/LabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 10
}Autochanger {Name = F14Device = F14-Dev1, F14-Dev2Changer Command = ""Changer Device = /dev/null
}

}

1.2.2.2Y机房

bacula-sd.conf中添加1个Device F3分别指向/cephfs/yz/目录
bacula-sd.conf新加配置如下：

Autochanger {Name = F3Device = F3-Dev1, F3-Dev2Changer Command = ""Changer Device = /dev/null
}Device {Name = F3-Dev1Media Type = File3Archive Device = /cephfs/yzLabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 5
}Device {Name = F3-Dev2Media Type = File3Archive Device = /cephfs/yzLabelMedia = yes;                   # lets Bacula label unlabeled mediaRandom Access = Yes;AutomaticMount = yes;               # when device opened, read itRemovableMedia = no;AlwaysOpen = no;Maximum Concurrent Jobs = 5
}

1.2.2.3调整bacula-dir配置

1. 把前面新添加的7个SD加到bacula-dir.conf中
2. T机房：把原来Job中的 Storage 都换成对应新建的Storage，例如原Storage = tt-7（/data1/backup_d7/）替换成现在Storage = tt-14（/cephfs/tt/backup_d7/）
3. Y机房：把原来Job中的 Storage 都换成对应新建的Storage = yz-3（亦庄把yz-1和yz-2在此做一个合并，合并到yz-3）
   bacula-dir.conf新加配置如下：

Storage {Maximum Concurrent Jobs = 10Name = tt-8SDPort = 9103Address = xxxxxxxxDevice = F8Password = "TFDk"Media Type = File8
}
Storage {Maximum Concurrent Jobs = 10Name = tt-9SDPort = 9103Address = xxxxxxxxDevice = F9Password = "TFDk"Media Type = File9
}
Storage {Maximum Concurrent Jobs = 10Name = tt-10SDPort = 9103Address = xxxxxxxxDevice = F10Password = "TFDk"Media Type = File10
}
Storage {Maximum Concurrent Jobs = 10Name = tt-11SDPort = 9103Address = xxxxxxxxDevice = F11Password = "TFDk"Media Type = File11
}
Storage {Maximum Concurrent Jobs = 10Name = tt-12SDPort = 9103Address = xxxxxxxxDevice = F12Password = "TFDk"Media Type = File12
}
Storage {Maximum Concurrent Jobs = 10Name = tt-13SDPort = 9103Address = xxxxxxxxDevice = F13Password = "TFDk"Media Type = File13
}
Storage {Maximum Concurrent Jobs = 10Name = tt-14SDPort = 9103Address = xxxxxxxxDevice = F14Password = "TFDk"Media Type = File14
}
Storage {Maximum Concurrent Jobs = 10Name = yz-3SDPort = 9103Address = xxxDevice = F3Password = "TFDk"Media Type = File3
}
