From 8c467ee8ef870d172b24e716130d7a0b6b882d6b Mon Sep 17 00:00:00 2001 From: Daan De Meyer Date: Wed, 12 Oct 2022 20:04:11 +0200 Subject: [PATCH] repart: Use COPY_REFLINK in context_copy_blocks() We might be copying between files without a loop device involved. In that case, a reflink is possible and will be much faster. --- src/partition/repart.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/partition/repart.c b/src/partition/repart.c index 94a87b97883..3a4f181370a 100644 --- a/src/partition/repart.c +++ b/src/partition/repart.c @@ -3200,7 +3200,7 @@ static int context_copy_blocks(Context *context) { log_info("Copying in '%s' (%s) on block level into future partition %" PRIu64 ".", p->copy_blocks_path, FORMAT_BYTES(p->copy_blocks_size), p->partno); - r = copy_bytes(p->copy_blocks_fd, target_fd, p->copy_blocks_size, 0); + r = copy_bytes(p->copy_blocks_fd, target_fd, p->copy_blocks_size, COPY_REFLINK); if (r < 0) return log_error_errno(r, "Failed to copy in data from '%s': %m", p->copy_blocks_path); -- 2.47.3
