NFS storage change IP and mounth path
-
Hello,
I'm using NFS as storage and I need to change target ip&path details.
I found some scripts for change these details but must be run old NFS and new NFS at same time, also this actions needs to run each host 1 by 1.
On Xen-Orchestra is there any easy and unpainful method to change NFS server ip&path details?
Thnak you.

@olivierlambert Wow, Thank you for your fast answer Oliver, I did this. But I didn' realise this changes needs to on XOA VM or each hosts?
-
You need to replace each PBD connected to this shared storage, yes. It's unrelated to XOA, since "editing" a PBD isn't possible, only recreate it.
That could be a feature in the future, I don't see any blocker to implement that with some automation in XO.

@olivierlambert Thanks again.
Another question: This unplug procedure takes loong time and mostly doesn't finish correctly. Is there any faster solution?
-
Is it because the NFS is already not available anymore?
-
@olivierlambert Yes, old nfs storage is already died.
-
In that case, that will need some extra stuff. You'll need to lazy umount (-l) each NFS mount so the PBD unplug works.

@olivierlambert Thank you. I'm not lazy but I'm little inexperienced about that problems
(btw Ansible really helpful for this kind of multi server cli based things) -
@olivierlambert As a 25+ years linux experienced man I learn another thing today.
umount - unmount file systems
-l Lazy unmount. Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not busy anymore. This option allows a "busy" filesystem to be unmounted. (Requires kernel 2.4.11 or later.)

That's why life is great, we can always learn new stuff
