Swift upload: "new bucket block: list chunk files: Cannot extract names from response with content-type: []" #713

Closed tivvit closed 4 years ago

tivvit commented 5 years ago

Hi

@sudhi-vm

Thanos, Prometheus and Golang version used thanos, version 0.2.1 (branch: HEAD, revision: 30e7cbdafd3ef01189f202945c2728fcf37e1cf1) build user: root@79ffcf51ff9b build date: 20181227-15:44:56 go version: go1.11.4

What happened I am having a problem with SWIFT store API

I can see it both in the sidecar and in store

What you expected to happen The sidecar should be able to close files

The store does not even start

How to reproduce it (as minimally and precisely as possible): started sidecar with configured SWIFT

Full logs to relevant components Here is the log from the sidecar

CC Swift client owner: @sudhi-vm

I think there are 2 issues here. Close error is not blocking anything I think (right?), but store looks like is blocking block loading.

tivvit commented 5 years ago

Yes the close issue looks like double close and the file looks like it was uploaded. The close error is no blocking - the sidecar is still working.

The store does not start because of the block load. But I am really not sure if the file is somehow corrupted from the sidecar or what is the problem.

pennpeng commented 5 years ago

@tivvit do you have any docs or blog to configuration thanos to use openstack swift？ please help me。

tivvit commented 5 years ago

@pennpeng I will publish the configuration. The configuration looks valid and is uploading files but it cannot be used due to the bug described in this issue.

bwplotka commented 5 years ago

@tivvit do you have time to give us a hand and run go test -v ./pkg/objstore/objtesting/... with export THANOS_SKIP_S3_AWS_TESTS='true' && export THANOS_SKIP_AZURE_TESTS='true' && export THANOS_SKIP_GCS_TESTS='true' && export THANOS_SKIP_TENCENT_COS_TESTS='true and Swift credentials configured?

This checks basic behaviour of the client. Might be something simple broken and reproducible by this acceptance test

FUSAKLA commented 5 years ago

@tivvit let me know if you need some help with this. Or if you struggle to find the time pass me the credentials and config internally and I can elaborate more on this. (we happen to be from the same company)

sudhi-vm commented 5 years ago

@bwplotka, @tivvit Just saw this, I'll take a look at it.

FlorinPeter commented 5 years ago

I ran into the same issue by using v0.6.1

FlorinPeter commented 5 years ago

after some local tests I found the issue and opened a PR #1489

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

FUSAKLA commented 4 years ago

Still valid. Just tried to migrate to Swift form S3 and failed with the same error message.

Hopefully should be fixed by https://github.com/thanos-io/thanos/pull/2665
