[Devel] [RH7 PATCH] ploop: reloc vs extent_conversion race fix
We have fixed most relocation bugs during fixing https://jira.sw.ru/browse/PSBM-47107 Currently reloc_a looks like follows: 1->read_data_from_old_post 2->write_to_new_pos ->sumbit_alloc ->submit_pad ->post_submit->convert_unwritten 3->update_index ->write_page with FLUSH|FUA 4->nullify_old_pos 5->issue_flush But on step 3 extent coversion is not yet stable because belongs to uncommitted transaction. We MUST call ->fsync inside ->post_sumit as we do for REQ_FUA requests. Let's tag relocatoin requests as FUA from very beginning in order to assert sync semantics. https://jira.sw.ru/browse/PSBM-49143 Signed-off-by: Dmitry Monakhov --- drivers/block/ploop/dev.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/block/ploop/dev.c b/drivers/block/ploop/dev.c index 40768b6..e5f010b 100644 --- a/drivers/block/ploop/dev.c +++ b/drivers/block/ploop/dev.c @@ -4097,7 +4097,7 @@ static void ploop_relocate(struct ploop_device * plo) preq->bl.tail = preq->bl.head = NULL; preq->req_cluster = 0; preq->req_size = 0; - preq->req_rw = WRITE_SYNC; + preq->req_rw = WRITE_SYNC|REQ_FUA; preq->eng_state = PLOOP_E_ENTRY; preq->state = (1 << PLOOP_REQ_SYNC) | (1 << PLOOP_REQ_RELOC_A); preq->error = 0; @@ -4401,7 +4401,7 @@ static void ploop_relocblks_process(struct ploop_device *plo) preq->bl.tail = preq->bl.head = NULL; preq->req_cluster = ~0U; /* uninitialized */ preq->req_size = 0; - preq->req_rw = WRITE_SYNC; + preq->req_rw = WRITE_SYNC|REQ_FUA; preq->eng_state = PLOOP_E_ENTRY; preq->state = (1 << PLOOP_REQ_SYNC) | (1 << PLOOP_REQ_RELOC_S); preq->error = 0; -- 1.8.3.1 ___ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
