ploop: force journal commit after dio_post_submit() Once we converted extent to initialized it can be part of uncompleted journal transaction, so we have to force transaction commit at some point. The easiest way to do it is to perform unconditional fsync. TODO: This case and others can be optimized by deferring fsync. But this is subject of another patch. https://jira.sw.ru/browse/PSBM-45730 Signed-off-by: Dmitry Monakhov <dmonak...@openvz.org> --- drivers/block/ploop/io_direct.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/block/ploop/io_direct.c b/drivers/block/ploop/io_direct.c index 8032999..5a2e12a 100644 --- a/drivers/block/ploop/io_direct.c +++ b/drivers/block/ploop/io_direct.c @@ -523,6 +523,8 @@ dio_post_submit(struct ploop_io *io, struct ploop_request * preq) err = io->files.file->f_op->fallocate(io->files.file, FALLOC_FL_CONVERT_UNWRITTEN, (loff_t)sec << 9, clu_siz); + if (!err) + err = io->files.file->f_op->FOP_FSYNC(io->files.file, 0); file_end_write(io->files.file); if (err) { PLOOP_REQ_SET_ERROR(preq, err); _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
