我刚刚安装了docker版本17.06.2-ee-3，在Red Hat 7.4版本上构建了915cbaa。当我尝试构建一个图像时，即使剩下足够的空间，它也会失败No space left on device。我发现这篇文章：https://jpetazzo.github.io/2014/01/29/docker-device-mapper-resize/可能不再适用了，但无论如何我都遵循了它，现在docker info显示：
Data Space Used: 30.68GB
Data Space Total: 268.4GB
Data Space Available: 134.7GB
Metadata Space Used: 32.23MB
Metadata Space Total: 2.147GB
Metadata Space Available: 2.115GB
我可以使用Docker版本1.7.1，构建786b29d以及带有docker版本1.11.1的Red Hat 7.2，构建5604cbe，使用Red Had 6.7成功构建相同的映像。
根据要求：

的请求，这是我收到空间信息时的输出：
force_basic_auth: True任何人都知道如何解决这个问题，并且实际上在这里使用docker？
答案 0 :(得分：3)
我终于解决了这个问题。在构建图像时使用trigger AutoConvert on Lead (after update) {
list<Lead> LeadsToConvert = new list<Lead>();
for(Lead myLead: Trigger.new){
if(!myLead.isConverted && myLead.API_Convert__c == true)
LeadsToConvert.add(myLead);
}
list<Database.LeadConvert> leadConverts = new list<Database.LeadConvert>();
for(Lead myLead : LeadsToConvert){
Database.LeadConvert lc = new database.LeadConvert();
lc.setLeadId(myLead.Id);
lc.convertedStatus = 'Qualified';
//Database.ConvertLead(lc,true);
lc.setDoNotCreateOpportunity(true);
leadConverts.add(lc);
}
if(!leadConverts.isEmpty()){
for(Integer i = 0; i <= leadConverts.size()/100 ; i++){
list<Database.LeadConvert> tempList = new list<Database.LeadConvert>();
Integer startIndex = i*100;
Integer endIndex = ((startIndex+100) < leadConverts.size()) ? startIndex+100: leadConverts.size();
for(Integer j=startIndex;j<endIndex;j++){
tempList.add(leadConverts[j]);
}
Database.LeadConvertResult[] lcrList = Database.convertLead(tempList, false);
for(Database.LeadConvertResult lcr : lcrList)
System.assert(lcr.isSuccess());
}
}
}
，我看到docker安装了一个10G的分区，里面装满了。我无法找到如何增加它，我与docker的某个人交谈，他告诉我把这些设置放在/etc/docker/daemon.json文件中：
watch df -h在我这样做并重新启动docker之后，挂载的分区是20G，我可以构建我的图像。
