Stuck Internal Snapshot

Ok - I know this is a very long shot for help, but here's the situation I'm in...

NS20 with CX3-10 - old, no support and I'm learning as I go.  It was our primary NAS for a few years, then we switched to NetApp and this system was retired about 4 years ago - just powered off after migrating data to the NetApp.  I'm trying to resurrect it to be used as a storage back end for VM Hosts in a prototyping environment for our developers - no expectations of backup or reliability.

Someone pulled 5 disks out of it, but I replaced them.  I've got the thing re-IP'd and it's responding well so far.  The SPS's are faulting, but everything else is pretty normal now. 

I removed all the old file systems from it except for one.  I removed the CIFS share and unmounted the file system, but it won't delete.  I've got two internal checkpoints that I can't get rid of.

[nasadmin@gshqcs01 bin]$ ./fs_ckpt cifs1 -list -all

id    ckpt_name                creation_time           inuse fullmark   total_savvol_used  ckpt_usage_on_savvol

99    root_rep_ckpt_32_28459_1 07/20/2009-11:57:55-EDT   n   N/A        N/A                N/A

100   root_rep_ckpt_32_28459_2 07/20/2009-11:58:02-EDT   n   N/A        N/A                N/A

You can see that they were created back in 2009, probably when the system was first stood up.

I've tried /nas/sbin/rootnas_fs -delete id=99 -o umount=yes -ALLOW_REP_INT_CKPT_OP

which everyone says should get rid of the internal replication checkpoints.  All this gets me is:

Error 5005: failed to complete command

I'm not seeing anything in the logs that explains the error in any more detail.

I'm hoping that there is some gracious soul out there that can help me remove the checkpoints and file system.  There has to be a way to wipe out a bad file system.

I did find the Replication Manager V5.1.0 software CD and Celerra Network Server 5.6.40.3 applications and tools cd - probably won't help at all though.

Thank you in advance!
