Greetings!
I have an issue with ZFS/NFS on OmniOS where copying or deleting large files causes the SAN to lockup and requires that we reboot it sometimes to recover. One customer was trying to copy a 400GB file and another tried to delete a 4TB vmdk from a vmware NFS vstore. In both situations the issue is reproducible and in both situations I cannot seem to find anything crazy happening on either of the boxes. This doesn’t mean anything though because I’m limited in my kstat/dtrace knowledge for troubleshooting this type of behavior on illumos. If there is an illumOS bug I’m missing or something that jumps out at ya please let me know…of if you need more detailed information I can detail both customer locations hardware, software, and operating conditions upon request. The VMware customer is running on r151016 and the other customer is running on the latest release. NFSv3 Only Clients OS: ESXi 5.5 All 64bit Linux Clients CentOS 5,6,&7 Some Older Debian 7 Boxes I should also note that the VMware customer experiences this same issue on two different SAN’s that are very different in hardware configurations. The one common thread is that they are all Sun Servers. X4170 M2, X4270 M2, x4540 This thread is being posted to both the illumos email list and the omnios email list as well. I’m looking, I guess, for a methodology to follow to trace this down and determine if it’s a bug or a misconfiguration either on the client or in ZFS or in the NFS server. I can get someone access if so desired. Have a great day!
