ovirt-shell

使用ovirt-shell在一定程度上适合于某些场景。

# ovirt-shell -I -u admin@internal -l https://server_ip/api

手动创建导出域

构造目录,形如:

# tree exports . ├── 37e0e64b-5445-4bc3-8675-ceff4637e8e3/ │   ├── dom_md/ │   │   ├── ids │   │   ├── inbox │   │   ├── leases │   │   ├── metadata │   │   └── outbox │   ├── /blog/images/ │   └── master/ │   ├── tasks/ │   └── vms/ └── __DIRECT_IO_TEST__

创建_leases_文件:

# echo 2d2d2d2d2d2d465245452d2d2d2d2d2d3030303030303030303030303030 303000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000 0000 | xxd -r -p > leases

添加如下内容至_metadata_文件:

CLASS=Backup DESCRIPTION=Export IOOPTIMEOUTSEC=10 LEASERETRIES=3 LEASETIMESEC=60 LOCKPOLICY= LOCKRENEWALINTERVALSEC=5 MASTER_VERSION=0 POOL_UUID= REMOTE_PATH=192.168.1.108:/home/nfs_exports ROLE=Regular SDUUID=37e0e64b-5445-4bc3-8675-ceff4637e8e3 TYPE=NFS VERSION=0

_SHA_CKSUM=5737f1270bf93fdd660fea819655b01a34c315b9

使用如下脚本(参考源码中packaging/setup/plugins/ovirt-engine-setup/config/iso_domain.py)计算SHA校验值,并将其填入_metadata_中的_SHA_CKSUM段:

!/usr/bin/python

import hashlib from optparse import OptionParser

if __name__ == "__main__": parser = OptionParser() (options, args) = parser.parse_args() if len(args) != 1: parser.error("Missing metadata file") f = open(args[0], "r") mds = {} for line in f: line = line.strip() if not line or line.startswith('#'): continue try: key,value = line.split('=', 1) if key == '_SHA_CKSUM': continue mds[key] = value except Exception, e: continue f.close() #print mds csum = hashlib.sha1() keys = mds.keys() keys.sort() for key in keys: value = mds[key] line = "%s=%s" % (key, value) csum.update(line) print(csum.hexdigest())

更改权限:

# chown -R vdsm.kvm exports

然后可以作为空导出域进行导入。
