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：

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：

复制代码

Autochanger {
  Name = F3
  Device = F3-Dev1, F3-Dev2
  Changer Command = ""
  Changer Device = /dev/null
}

Device {
  Name = F3-Dev1
  Media Type = File3
  Archive Device = /cephfs/yz
  LabelMedia = yes;                   # lets Bacula label unlabeled media
  Random Access = Yes;
  AutomaticMount = yes;               # when device opened, read it
  RemovableMedia = no;
  AlwaysOpen = no;
  Maximum Concurrent Jobs = 5
}

Device {
  Name = F3-Dev2
  Media Type = File3
  Archive Device = /cephfs/yz
  LabelMedia = yes;                   # lets Bacula label unlabeled media
  Random Access = Yes;
  AutomaticMount = yes;               # when device opened, read it
  RemovableMedia = no;
  AlwaysOpen = no;
  Maximum Concurrent Jobs = 5
}

1.2.2.3调整bacula-dir配置

把前面新添加的7个SD加到bacula-dir.conf中
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/）
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 = 10
Name = tt-8
SDPort = 9103
Address = xxxxxxxx
Device = F8
Password = "TFDk"
Media Type = File8
}
Storage {
Maximum Concurrent Jobs = 10
Name = tt-9
SDPort = 9103
Address = xxxxxxxx
Device = F9
Password = "TFDk"
Media Type = File9
}
Storage {
Maximum Concurrent Jobs = 10
Name = tt-10
SDPort = 9103
Address = xxxxxxxx
Device = F10
Password = "TFDk"
Media Type = File10
}
Storage {
Maximum Concurrent Jobs = 10
Name = tt-11
SDPort = 9103
Address = xxxxxxxx
Device = F11
Password = "TFDk"
Media Type = File11
}
Storage {
Maximum Concurrent Jobs = 10
Name = tt-12
SDPort = 9103
Address = xxxxxxxx
Device = F12
Password = "TFDk"
Media Type = File12
}
Storage {
Maximum Concurrent Jobs = 10
Name = tt-13
SDPort = 9103
Address = xxxxxxxx
Device = F13
Password = "TFDk"
Media Type = File13
}
Storage {
Maximum Concurrent Jobs = 10
Name = tt-14
SDPort = 9103
Address = xxxxxxxx
Device = F14
Password = "TFDk"
Media Type = File14
}
Storage {
Maximum Concurrent Jobs = 10
Name = yz-3
SDPort = 9103
Address = xxx
Device = F3
Password = "TFDk"
Media Type = File3
}
