Loading... # 错误 ## platform.linux_distribution问题 ### 表现 ``` RuntimeError: AttributeError: module 'platform' has no attribute 'linux_distribution' ``` ### 原因 在Python 3.8及更高版本中，platform.linux_distribution已经被删除了，所以ceph会报错。 ### 解决 解决方法简单粗暴，直接修改程序逻辑就好。 编辑 /usr/lib/python3/dist-packages/ceph_deploy/hosts/remotes.py 然后找到platform_information函数，将下列两行用try语句包裹: ``` linux_distribution = _linux_distribution or platform.linux_distribution distro, release, codename = linux_distribution() ``` 然后设置三个变量的默认值，修改后是这样的: ``` def platform_information(_linux_distribution=None): """ detect platform information from remote host """ """ linux_distribution = _linux_distribution or platform.linux_distribution distro, release, codename = linux_distribution() """ distro = release = codename = None try: linux_distribution = _linux_distribution or platform.linux_distribution distro, release, codename = linux_distribution() except AttributeError: pass ``` 保存退出，然后再次尝试运行。 ## ceph-deploy文本显示问题 ### 表现 ``` [a1][INFO ] Running command: sudo fdisk -l [ceph_deploy][ERROR ] Traceback (most recent call last): [ceph_deploy][ERROR ] File "/usr/lib/python3/dist-packages/ceph_deploy/util/decorators.py", line 69, in newfunc [ceph_deploy][ERROR ] return f(*a, **kw) [ceph_deploy][ERROR ] File "/usr/lib/python3/dist-packages/ceph_deploy/cli.py", line 166, in _main [ceph_deploy][ERROR ] return args.func(args) [ceph_deploy][ERROR ] File "/usr/lib/python3/dist-packages/ceph_deploy/osd.py", line 434, in disk [ceph_deploy][ERROR ] disk_list(args, cfg) [ceph_deploy][ERROR ] File "/usr/lib/python3/dist-packages/ceph_deploy/osd.py", line 375, in disk_list [ceph_deploy][ERROR ] if line.startswith('Disk /'): [ceph_deploy][ERROR ] TypeError: startswith first arg must be bytes or a tuple of bytes, not str [ceph_deploy][ERROR ] ``` ### 原因 类型不通问题，需要以bytes形式匹配。 ### 解决 打开 /usr/lib/python3/dist-packages/ceph_deploy/osd.py 查找下列代码: ``` if line.startswith('Disk /'): ``` 将其替换为: ``` if line.startswith(b'Disk /'): ``` 保存退出，重新运行即可。 ## 残留Block问题 如果用ceph-deploy强制删除了原来的集群，那原来的OSD可能会保留在磁盘内。 所以当再次部署的时候，使用ceph-deploy擦除磁盘的时候可能导致异常情况: ``` [x1][INFO ] Running command: /usr/sbin/ceph-volume lvm zap /dev/sdb [x1][WARNIN] --> Zapping: /dev/sdb [x1][WARNIN] --> --destroy was not specified, but zapping a whole device will remove the partition table [x1][WARNIN] stderr: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy [x1][WARNIN] --> failed to wipefs device, will try again to workaround probable race condition [x1][WARNIN] stderr: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy [x1][WARNIN] --> failed to wipefs device, will try again to workaround probable race condition [x1][WARNIN] stderr: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy [x1][WARNIN] --> failed to wipefs device, will try again to workaround probable race condition [x1][WARNIN] stderr: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy [x1][WARNIN] --> failed to wipefs device, will try again to workaround probable race condition [x1][WARNIN] stderr: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy [x1][WARNIN] --> failed to wipefs device, will try again to workaround probable race condition [x1][WARNIN] stderr: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy [x1][WARNIN] --> failed to wipefs device, will try again to workaround probable race condition [x1][WARNIN] stderr: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy [x1][WARNIN] --> failed to wipefs device, will try again to workaround probable race condition [x1][WARNIN] stderr: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy [x1][WARNIN] --> failed to wipefs device, will try again to workaround probable race condition [x1][WARNIN] --> RuntimeError: could not complete wipefs on device: /dev/sdb [x1][ERROR ] RuntimeError: command returned non-zero exit status: 1 [ceph_deploy][ERROR ] RuntimeError: Failed to execute command: /usr/sbin/ceph-volume lvm zap /dev/sdb ``` 要想解决这个问题，就得手动删除磁盘中残余的Block，先用lsblk查看磁盘情况 ``` lsblk ``` 我这边显示的情况是: ``` NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop1 7:1 0 55.5M 1 loop /snap/core18/2409 loop2 7:2 0 71.3M 1 loop /snap/lxd/16099 loop3 7:3 0 61.9M 1 loop /snap/core20/1518 loop4 7:4 0 67.8M 1 loop /snap/lxd/22753 loop5 7:5 0 47M 1 loop /snap/snapd/16292 loop6 7:6 0 55.6M 1 loop /snap/core18/2538 sda 8:0 0 50G 0 disk ├─sda1 8:1 0 1M 0 part └─sda2 8:2 0 50G 0 part / sdb 8:16 0 1T 0 disk └─ceph--66fb0189--7b8a--423e--a26c--f4a85545f396-osd--block--df953059--5020--4c8c--8b82--4dd8a22a0b1c 253:0 0 1024G 0 lvm rbd0 252:0 0 20G 0 disk rbd1 252:16 0 20G 0 disk rbd2 252:32 0 2G 0 disk rbd3 252:48 0 20G 0 disk rbd4 252:64 0 4G 0 disk rbd5 252:80 0 8G 0 disk rbd6 252:96 0 8G 0 disk rbd7 252:112 0 8G 0 disk ``` 可以看到在要抹除的磁盘/dev/sdb下，存在一个前ceph集群残留的存储块: ceph--66fb0189--7b8a--423e--a26c--f4a85545f396-osd--block--df953059--5020--4c8c--8b82--4dd8a22a0b1c 把它擦除掉就好了 ``` sudo dmsetup remove --force ceph--66fb0189--7b8a--423e--a26c--f4a85545f396-osd--block--df953059--5020--4c8c--8b82--4dd8a22a0b1c ``` 删除这个block之后，磁盘里可能还存在一些LVM或者分区，用wipefs强行写入删除: ``` wipefs -af /dev/sdb ``` 最后修改：2025 年 01 月 15 日 © 允许规范转载 赞 如果这对你有用，我乐意之至。
