From 118bc193b0905f5afb79bad31364573de971b7bc Mon Sep 17 00:00:00 2001 From: Gorka Eguileor Date: Thu, 31 May 2018 10:51:03 +0200 Subject: [PATCH] spec: Fix grammatical error We have a several instances of "does not exists" in the spec, probably caused by copy-pasting. To fix it and prevent new cases from appearing, this patch replaces it with the proper "does not exist". --- spec.md | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/spec.md b/spec.md index 2c5f3044..f2bfa4ae 100644 --- a/spec.md +++ b/spec.md @@ -897,8 +897,8 @@ The CO MUST implement the specified error recovery behavior when it encounters t | Condition | gRPC Code | Description | Recovery Behavior | |-----------|-----------|-------------|-------------------| -| Volume does not exists | 5 NOT_FOUND | Indicates that a volume corresponding to the specified `volume_id` does not exist. | Caller MUST verify that the `volume_id` is correct and that the volume is accessible and has not been deleted before retrying with exponential back off. | -| Node does not exists | 5 NOT_FOUND | Indicates that a node corresponding to the specified `node_id` does not exist. | Caller MUST verify that the `node_id` is correct and that the node is available and has not been terminated or deleted before retrying with exponential backoff. | +| Volume does not exist | 5 NOT_FOUND | Indicates that a volume corresponding to the specified `volume_id` does not exist. | Caller MUST verify that the `volume_id` is correct and that the volume is accessible and has not been deleted before retrying with exponential back off. | +| Node does not exist | 5 NOT_FOUND | Indicates that a node corresponding to the specified `node_id` does not exist. | Caller MUST verify that the `node_id` is correct and that the node is available and has not been terminated or deleted before retrying with exponential backoff. | | Volume published but is incompatible | 6 ALREADY_EXISTS | Indicates that a volume corresponding to the specified `volume_id` has already been published at the node corresponding to the specified `volume_id` but is incompatible with the specified `volume_capability` or `readonly` flag . | Caller MUST fix the arguments before retying. | | Volume published to another node | 9 FAILED_PRECONDITION | Indicates that a volume corresponding to the specified `volume_id` has already been published at another node and does not have MULTI_NODE volume capability.
