HDD/RAID changes only with DSS reboot ?!

[HangaS]

Hi,

I just have the same issue here but with a 3ware 9650SE-8LPML.
I had 3 1TB units in RAID5, I added a 4th unit to the array using the 3DM2 interface, no hassles here. The array was expanded online on the live without any need to reboot or other downtime.

Now I want that extra space to be visible in DSS, I tryed Rescan in Volume manager, but the old unit size shows up.

Do I need to reboot DSS in order for it to see the extra space??

Well, I found that the reboot is not really necessary in a response on another topic. However the system got quite unstable since then, with NAS shares not showing up.

I believe that the Resize LV option reseted my connections and somehow the servers could not reconnect afterwards.. :|

Did the RAID complete the migration and if it did and rescan did not work to see the new unit try the PV Resize tool located in the Console screen in the Extended tools menu (CTRL + ALT + X).

Any errors in the event viewer?

Yes, the PV Resize did it, but the connections were all reset, and some NFS mounts got stale.

The problem is that when I did the PV Resize, the tools didn't show up a warning stating that connections could be reset, otherwise I would have done that sometime later when most users were not affected.

The same is true for enabling Volume replication.
All connections for this volume are lost without a warning!
