From f3433ed1a5176bff85b3fe04dba2d4c76618a299 Mon Sep 17 00:00:00 2001 From: whoami-rajat Date: Tue, 25 Jan 2022 19:24:30 +0530 Subject: Cinder store: Wait for device resize When we have an image with size > 1 GB, we follow the following steps to accomodate the image: 1) Detach the volume 2) extend the volume 3) Attach the volume 4) Open the volume device as a file and resume writing the image Sometimes due to several reasons (mostly network related), the size of the device file could mismatch with the actual volume size (or the backend LUN size). This can happen if the extend was performed (i.e. the control path) but it takes the time to reflect that into the mapped device (i.e. the data path). This mismatch can cause the issue "IOError: [Errno 28] No space left on device". To avoid this scenario, we check if the device size is less than the volume size, we wait for the extended LUN to show up in mapped device and then continue the image writing operation.
