Move "Shares" between Logical Volumes

How can I move an existent "Share" to another "Logical Volume"?
P.S.: This move must be performed "online" -> No downtime possible.

Thanks a lot!

I have not seen any mechanisms to transfer logical volume *contents* online from one logical volume to another. IMO this would require another access layer above the file system, which I have not seen yet.

So just for clarification: Do you not only want to move the share, but its data as well? And "online" means not only the DSS has to remain online, but the share and it's using clients as well?

Even with (temporary) read-only access to the share, I only see a disruptive way of moving the share:
- make the original share r/o
- copy the share's content to the new location
- change the share's storage location
- delete the data at the share's original location

But I would expect this to disrupt the share's clients connections.

Hi JMO!

The backround is as follows:

- Clients which are using an existent share "Datashare1".
-> I would like to move this "Datashare1" to another Logical Volume (at another VolumeGroup with more disc space).
- Users/Clients which are mounting the share "Datashare1" should not notice any change!
-> I can do that move at night (no user online) but i can not restart the whole server/using knoppixx etc.

Hi Stefan,

now that actually does sound easy:
- make the "old" share r/o (just to make sure no one interferes with the following actions)
- create a temporary share for the new LV/path (if not available via an already defined share for some up-level directory) with write permissions
- at some client, mount both shares
- move the content from old share to new share
- change the "old share" definition to point to the new directory and re-enable r/w

Done. Oh, and YMMV ;)

Regards,
Jens

-> How can I do this? "NAS Resources" -> "Path" could not edited after initial creation.

Oops, I don't have access to an DSS at the moment, so I couldn't check in advance. According to the manual this should be possible, see section 5.2.2.3.1:
--- cut here ---
You will find all existing shares organized below. You can edit them with a simple click. All
parameters except the name are modifiable.

If it really won't work, then you'll have to delete the old share and recreate it, including the permission settings :eek:

With regards,

Hi Jens,

My fault... manual edit of the path destination is not possible but with mouse-action you can browse to the designated lv/folder.

I will create a "temp" share with the destination folder (at destination lv/vg), move files, and than edit the path of the original share to the new folder and delete "temp" share.

Thanks a lot for your assistance!
