Comment #3 on issue 269 by [email protected]: gnt-instance grow-disk does not work in ganeti 2.6.0
http://code.google.com/p/ganeti/issues/detail?id=269
This issue is pretty weird. It seems like some odd interaction with config references (the disks in this case). However, I'm not able to reproduce it for debugging :(. Do you have that only with that specific instance or with all of them?
I could track it to two possible changes (from 2.5 to 2.6) verified using: git blame v2.5.1.. -L'/^class LUInstanceGrowDisk/,/^class/' lib/cmdlib.py
One is commit e7f99087 the other one is commit 62bfbc7d. Beside of those two commits nothing has changed code in that regard.
I verified using drbd and plain (as your instance is plain) instance disks. Both worked in my environment.
