I have a weird issue with a couple of CDOT 8.3 simulators. I just set up two sets of two-node clusters, i.e. four simulators in total, stored in one VMware datastore over NFS. After configuring the sims for our lab and training needs, I halted them and created a snapshot of the datastore volume. Next step was to create a FlexClone of the datastore volume, mount it under a new name and register the sims with four new unique names. Question "Moved or copied" is answered "Copied". I have done this MANY times with older versions of CDOT and 7mode sims.
This time, all four sims panics with the following message:
WAFL CPLEDGER is enabled. Checklist = 0x7ff841ff
PANIC : prod/common/wafl/free_cache.c:909: Assertion failure.
version: 8.3: Mon Mar 9 19:20:57 PDT 2015
conf : x86_64.sim
cpuid = 0
Uptime: 51s
recursive PANIC: page fault (supervisor read data, page not present) on VA 0xd0

cpuid = 0
Uptime: 51s
The operating system has halted.
Please press any key to reboot.
(hopefully I typed everything correctly, since there is no way to copy&paste from the vSphere console...
The changes I have made to the sims are
- Added four Ethernet ports
- Changed systemid on the second nodes of each cluster to match the licenses
- Removed pre-configured disks in systemshell and added 32 x 9GB FC (type 36) and 16 x 500MB SSD (type 35). These sizes should be supported in 8.3, but did I add too many?
If I power on the original sims in the parent FlexVol then these work just fine. So question is what happens during the clone. As I said, I have done this dozens of times before with other releases.
Any help appreciated.
