DRBD编译安装中出现的问题及解决小结

erwerwe

问题1:
设置primary node时提示不能成功UpToDate data:

1 2 3

# drbdadm primary r1       r1: State change failed: (-2) Need access to UpToDate data Command 'drbdsetup primary r1' terminated with exit code 17

解决:

1 2 3

# drbdadm primary --force r1          ##强制设置 # drbd-overview 1:r1/0  Connected(1*) Primary(1*) UpToDate(1*)

问题2:
创建设备元数据时提示操作失败:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

# drbdadm -c /etc/drbd.conf create-md all md_offset 314568704 al_offset 314535936 bm_offset 314523648 Found ext3 filesystem       307200 kB data area apparently used       307152 kB left usable by current configuration        Device size would be truncated, which would corrupt data and result in 'access beyond end of device' errors. You need to either    * use external meta data (recommended)    * shrink that filesystem first    * zero out the device (destroy the filesystem) Operation refused. Command 'drbdmeta 1 v09 /dev/sdb1 internal create-md 1' terminated with exit code 40

解决:

1	# dd if=/dev/zero of=/dev/sdb1 bs=1M count=100

问题3:
启用资源时提示失败，无法创建transport:

1 2 3 4

# drbdadm up r1 r1: Failure: (172) Failed to create transport (drbd_transport_xxx module missing?) Command 'drbdsetup new-peer r1 1 --_name=node2 --shared-secret=123456 --cram-hmac-alg=sha1 --protocol=C' terminated with exit code 10 drbdadm: new-path r1: skipped due to earlier error

解决:
安装drbd_transport_tcp模块

1 2 3 4 5 6

# cp drbd_transport_tcp.ko /lib/modules/3.10.0-229.el7.x86_64/kernel/lib/ # depmod   # modprobe drbd_transport_tcp # lsmod|grep drbd_transport_tcp drbd_transport_tcp     17731  0 drbd                  463948  2 drbd_transport_tcp

问题4:
启用资源时提示失败，配置要求无效:

1 2 3 4 5

# drbdadm up r1 r1: Failure: (162) Invalid configuration request additional info from kernel: minor exists as different volume Command 'drbdsetup new-minor r1 1 1' terminated with exit code 10

解决:
安装drbd模块

1 2 3 4 5 6 7

#  cd drbd-9.0.0/drbd # cp drbd.ko /lib/modules/3.10.0-229.el7.x86_64/kernel/lib/ # depmod # modprobe drbd # lsmod |grep drbd drbd                  463948  0 libcrc32c              12644  2 xfs,drbd

问题5:
启动资源时提示失败，设备或资源忙

1 2 3 4 5 6 7 8 9 10

# drbdadm up r1 No valid meta data found Command 'drbdmeta 1 v09 /dev/sdb1 internal apply-al' terminated with exit code 255 # drbdadm create-md all open(/dev/sdb1) failed: Device or resource busy Exclusive open failed. Do it anyways? [need to type 'yes' to confirm] yes # Output might be stale, since minor 1 is attached Device '1' is configured! Command 'drbdmeta 1 v09 /dev/sdb1 internal create-md 1' terminated with exit code 20

解决:
fdisk /dev/sdb 删除该分区保存，然后再重新新建分区并保存即可



问题6:
提示unknown resource

1 2 3 4 5

# drbdadm primary r1 r1: Failure: (158) Unknown resource additional info from kernel: unknown resource Command 'drbdsetup primary r1' terminated with exit code 10

解决:

1	# /etc/init.d/drbd start

问题7:

1 2	# drbd-overview 1:r1/1  Connec/Connec Second/Unknow UpToDa/DUnkno

1	# systemctl stop firewalld

1 2	# drbd-overview 1:r1/1  Connec/StaAlo Second/Unknow Outdat/DUnkno

1	# getenforce 0
