The showmount commands shows the contents of the rmtab file. In theory, when something is unmounted, the entry should be removed, but it isn't guaranteed and you end up having the stale entries. I don't think there is a way to clean that up - except likely by rebooting or restarting the NFS service. You might be able to manually remove the entries from the file, depending on the version of data ontap, but there would be a concern that the NFS service may get a bit messed up if things were removed that shouldn't have been. ...

Snapshot growth comes from deletions or changes. Would there have been any sort of backup file being written to the file share? It will be difficult to pin point the exact cause of the size of the snapshots, especially if there are a lot of files / folder owners in the volume. ... View more

Just for clarification:   Volume A - the source volume - does this have the snapshots you are trying to identify? If it has the default snapshot schedule assigned, Data OnTap will be creating the snapshots. Volume DR_A - the destination volume - this should show the same snapshots on the source volume if it is a regular mirror, or it could have additioanl ones if it is a vault mirror.   The snapmirror relationship will also generate snapshots, that relationship can be created via Unified Manager or the CLI. You can compare the snapmirror-label to see if it matches the snapshots you are seeing.   Have you shown the volume show for both the source and destination volumes?     ... View more

You have to split the ownership if you want 12 disks used for each node.   You can have an odd number of disks in a raid group, that's no problem. Whether you have 1 or 2 spares is a personal choice. One spare would give you more usable capacity. If you know you could get a replacement disk quickly - then 1 spare should be fine. If it might take awhile to get a replacement on site, you may want to have more than 1. ... View more

As noted above, user / admin guides will help clarify things immensely.   In terms of SnapVault and SnapMirror status - IDLE status is fine, noting the amount of lag is a good key indicator of an issue. If the lag time is less than the time frame of the schedule (if it is a daily vault and the lag time is less than 24 hours), then usually everything is ok.   If there are other issues, the status will reflect that. ...

Depends on what you mean by performance impact. The clone is on the same filer and same aggregate as the parent volumes, so any extremely heavy activity on the clone could have an impact on any other volume on that filer / aggregate depending on the model of filer and size of aggregate. But having the clone read the same blocks as the parent could actually be beneficial if the blocks are already in cache from the other servers read request. ... View more

Maybe you have already done this, but I would ensure the shelves were disconnected from both filers, then confirm shelf IDs and set all speeds to 2 or 4 (have you verifed the adpater you are using is capable of 4?), then power cycle the shelves. After connect them to each other and then connect them to the controllers one link at a time, verifying that the controller can see the shelves after each individual connection. If you can't see all the disks on the first connection to the filer, you should look at cable connections / replace cables / reseat modules before attempting to add any further connections to the controllers. ...
