Hi Josef, Just a friendly ping, I am more than happy to test a patch, if you send it inline in the email, since the pastebin you used expired after 1 day, and I couldn't access it. I came across and tested Yu Kuai's patches [1][2] which are for the same issue, and they indeed fix the hang. Thank you Yu.
Hi, Matthew Thanks for your test.
[1] nbd: don't clear 'NBD_CMD_INFLIGHT' flag if request is not completed https://lists.debian.org/nbd/2022/04/msg00212.html [2] nbd: fix io hung while disconnecting device https://lists.debian.org/nbd/2022/04/msg00207.html I am also happy to test any patches to fix the I/O errors.
Sorry that I missed this thread. IMO, if inflight requests is cleared by ioctl NBD_CLEAR_SOCK after my patch [2](or other callers for nbd_clear_que()), such io will return as error. Thus I don't think such io errors need to be fixed. Josef, do you have other suggestions? Thanks, Kuai
