Can I use same secret key for mutual authentication in the case of LUN export?
No. The key must be unique.
What is the maximum number of NFS or iSCSI LUNs that you can have on ElastiStor?
You can create N number of NFS or iSCSI LUNs based on your requirement.
Can I send an I/O of 1MB size in a single request on NFS?
Yes. NFS volumes are currently allowed to be mounted with an rsize/wsize of 1M. You can use the following sample mount option:
mount -o vers=3,rsize=1048576,wsize=1048576,mountproto=tcp,sync 126.96.36.199:/acctsample /mnt/nfslocal/
Can I disable the configuration options related to the protocols I do not use, in ElastiCenter?
Yes. The current release supports disabling of FC-specific options.
- In the ElastiCenter, click admin > Global Settings.
- Go to
ui.protocol.enablefc, click the Edit icon, and then specify
- For the changes to take effect, either relogin to ElastiCenter or refresh the browser.
All FC-specific options disappear from ElastiCenter UI.
When I use FC I see a LUN with the ID 0 and size 1MB displayed though i did not create it. Why?
This is a system LUN and is not for use.
Deleting data on my CIFS share doesn’t increase the free space. Why?
This is because the data is not permanently deleted. Instead, data is moved to the CIFS share recycle bin. To delete data permanently, do the following:
- In the Storage Volumes page, select a CIFS Storage Volume.
- Click Manage CIFS configuration in the actions pane.
- Click Edit and then disable the CIFS share Recycle bin option.
- Click Save.
On Windows client
If you have not disabled this option (earlier) and then data is already moved to the CIFS share Recycle Bin, to clear the data, you must do the following:
- (If Show hidden files and folders option is enabled) Go to the folder .recycle and then clear the data.
- (If Show hidden files and folders option is disabled) Do the following:
- Go to Control Panel > Folder Options > View tab.
- Enable hidden files, folders, and drives. Now you can view the .recycle folder.
- Clear the data.
I am on a common NFS Share. Is there a way to restrict an other user on this share from deleting my files?
Yes. If you want a home directory kind of NFS share, when configuring the NFS Storage Volume (see the following screen), set the option
Map as Root Users to No.
I changed the primary IP address of the VSM. Now I cannot access the iSCSI Storage Volumes. What should I do?
Do the following:
- Log out of all the iSCSI Volumes on the clients.
- Delete the login entries of the VSM on the clients.
- Relogin to the clients with the new IP address.
