你好,

这是昨天的新闻，但是如果你错过了它，在vSphere 5.5U1中似乎有一个影响所有NFS用户的bug。

NetApp和VMware(至少，Nutanix也是)正在研究这个课题。

查看下面的帖子获取更多信息:
http://datacenterdude.com/vmware/nfs-disconnects-vmware-vsphere/

这也可能解释了Nutanix在支持5.5U1?
你们在没有5.5U1支持的情况下发现这个问题了吗?

Sylvain。

    \nIt's made the news yesterday, but in case you missed it, there seems to be a bug within vSphere 5.5U1 that affects all NFS users.
    \n
    \nNetApp & VMware (at least, maybe Nutanix too?) are working on the subject.
    \n
    \nSee the post below for more information:
    \nhttp:\/\/datacenterdude.com\/vmware\/nfs-disconnects-vmware-vsphere\/
    \n
    \nThat may also explain the delay from Nutanix in the support of the 5.5U1?
    \nDid you guys catch this while working no the 5.5U1 support?

    ESXi 5.5 U1 NFS数据存储断开的问题在内部和我们的客户中都发生了。昨天已经向我们的客户发送了17号现场咨询，建议他们推迟对ESXi 5.5的任何升级。U1。

    看来vmware刚刚在这个问题上发布了KB-2076392。

    ESXi升级到5.5 U1后NFS频繁apd (2076392)
    现象描述在运行ESXi 5.5 Update 1时，发现ESXi主机经常与NFS存储失去连通性，并出现apd到NFS卷的现象。您会遇到以下症状:
    • 报告了针对NFS数据存储的间歇apd，这可能会导致Windows虚拟机客户端和Linux虚拟机中的只读文件系统出现蓝屏错误。请注意: NFS卷包括VSA数据存储。
    • 在APD条件期间和之后，阵列仍然响应ping, netcat测试也成功，没有证据表明物理网络或NFS存储阵列问题。
    • NFS阵列的日志和跟踪也没有明显的问题，其他未运行ESXi 5.5 U1的主机可以正常工作，对NFS共享读写也没有问题。
    • 你可以在vobd日志中看到类似的条目:请注意:这些日志条目以12345678-abcdefg0卷为例:2014-04-01T14:35:08.074Z: [APDCorrelator] 9413898746us: [vob.storage.apd. volume .]设备或文件系统的标识符[12345678-abcdefg0] has entered the All Paths Down state。设备或文件系统的标识符[12345678-abcdefg0] has entered the All Paths Down state.2014-04-01T14:36:55.274Z: No correlator for vob.vmfs.nfs.server.disconnect2014-04-01T14:36:55.274Z: [vmfsCorrelator] 9521467867us: [esx. issue .vmfs.nfs.server.]disconnect] 192.168.1.1/NFS-DS1 12345678-abcdefg0-0000-000000000000 NFS-DS12014-04-01T14:37:28.081Z: [APDCorrelator] 9553899639us: [vob.storage.apd. storage.apd. storage. abcdefg0-0000-000000000000timeout]标识符[12345678-abcdefg0]的设备或文件系统处于All Paths Down状态140秒后进入All Paths Down超时状态。I/ o现在将会快速失败。timeout]标识符[12345678-abcdefg0]的设备或文件系统处于All Paths Down状态140秒后进入All Paths Down超时状态。I/ o现在会快速失败。
    该问题已知影响ESXi 5.5 Update 1主机，且NFS存储已连接。VMware正致力于为客户提供解决方案。为了解决此问题，VMware建议使用ESXi 5.5 GA。

    \nFrequent NFS APDs after upgrading ESXi to 5.5 U1 (2076392)
    \nSymptomsWhen running ESXi 5.5 Update 1, the ESXi host frequently loses connectivity to NFS storage and APDs to NFS volumes are observed. You experience these symptoms:
    \n
      \n
    • Intermittent APDs for NFS datastores are reported, with consequent potential blue screen errors for Windows virtual machine guests and read-only filesystems in Linux virtual machines.Note<\/b>: NFS volumes include VSA datastores. \n
    • For the duration of the APD condition and after, the array still responds to ping and netcat tests are also successful, and there is no evidence to indicate a physical network or a NFS storage array issue. \n
    • The NFS storage array logs and traces also do not indicate any evident issue, other hosts not running ESXi 5.5 U1 continue to work and can read and write to the NFS share without issue. \n
    • You see entries in the vobd logs similar to:Note<\/b>: These log entries use the 12345678-abcdefg0 volume as an example:2014-04-01T14:35:08.074Z: [APDCorrelator] 9413898746us: [vob.storage.apd.start] Device or filesystem with identifier [12345678-abcdefg0] has entered the All Paths Down state.2014-04-01T14:35:08.075Z: [APDCorrelator] 9414268686us: [esx.problem.storage.apd.start] Device or filesystem with identifier [12345678-abcdefg0] has entered the All Paths Down state.2014-04-01T14:36:55.274Z: No correlator for vob.vmfs.nfs.server.disconnect2014-04-01T14:36:55.274Z: [vmfsCorrelator] 9521467867us: [esx.problem.vmfs.nfs.server.disconnect] 192.168.1.1\/NFS-DS1 12345678-abcdefg0-0000-000000000000 NFS-DS12014-04-01T14:37:28.081Z: [APDCorrelator] 9553899639us: [vob.storage.apd.timeout] Device or filesystem with identifier [12345678-abcdefg0] has entered the All Paths Down Timeout state after being in the All Paths Down state for 140 seconds.

    谢谢,非常清晰。

    太糟糕了，我们本来打算下周测试5.5U1，下个月开始大规模推出，估计我们得等等了……

    \nToo bad, we were to test the 5.5U1 just next week to rollout massively starting next month, guess we'll have to wait...

    当然你已经知道了，但是如果有人看到这个帖子并且不知道的话，这周VMware发布了一个5.5U1的补丁。我相信Nutanix正在进行内部测试。我们急切地等待结果
