Hi Changhui,
The hang is actually expected because recovery fails.
Please pull the latest ublksrv and check if the issue can still be
reproduced:
https://github.com/ublk-org/ublksrv
BTW, one ublksrv segfault and two test cleanup issues are fixed.
Thanks,
Ming
Hi,Ming and Nan
after applying the new patch and pulling the latest ublksrv,
I ran the test for 4 hours and did not observe any task hang.
the test results looks good！
Thanks，
Changhui
.
Thanks for you test!
However, I got a NULL pointer dereference bug with ublksrv. It is not
introduced by this patch. It seems io was issued after deleting disk. And
it can be reproduced by:
while true; do make test T=generic/004; done
Hi,Nan
I can not reproduce this issue with repo
https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux-block.git/log/?h=for-next
,
which kernel repo do you using for test?
Thanks,
Changhui
I tested with the latest block code, commit
2ab79514109578fc4b6df90633d500cf281eb689, this issue also can be
reproduced.
The space of the root path has been filled up by
ublksrv(tests/tmpublk_loop_data_xxx), which may the issue be related to this?
