<p class="MsoNormal" style="text-indent:.5in"><span style="font-size:11.0pt">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.
