I've been noticing a strange one in our clusters. We have a vmfs datastore which a small cluster of x6 hosts writes to for their scratch partition. Each host writes their scratch to a different folder. What I have been noticing, is that when rebooting the cluster at the same time, they will randomly lose access to the datastore, with the following error in the vmkernel.log.. Failed to open device naa.60002ac0000000000000000200020cb8:1 : Atomic test and set of disk block returned false for equality Straight after that the logs show other datastores being mounted OK. I am struggling to fix this, as it seems totally random, but only seems to occur when all 6 hosts are rebooted at the same time. Something is not right if thats all it takes! Has anyone seen that before? Google comes up with literally nothing. |

What type of FC HBA, driver and firmware? I had this issue some time ago. Root cause what buggy FC HBA driver that was just recently fixed (April or so this year). |

Software iscsi in Esxi! Had all sorts of funny stuff with LLDP agents on intel, and another odd behaviour where I cannot enable two dual 10Gbe cards for SR-IOV, only one enables and the other disables. I shall not question, hooking together enterprise systems in the modern day is nothing what it used to be like. So many bugs, so many workarounds, just to try and get a working setup. |

Hehe. Yeah. Not saying everything was better before, but it was a lot less complex. I would probably log a case with Vmware on that one. They had a ESXi workaround for me with the buggy drivers. |
