Re: [Libguestfs] [PATCH] parted: add more udev_settle calls.

add udev_settle calls to print_partition_table and sgdisk_info_extract_field because the inspect-os calls guestfs_part_get_parttype and guestfs_part_get_gpt_guid for all parition devices found and this causes intermittent with opening block devices that are certainly present yet RESOLVE_DEVICE macro would fail wiht ENOENT. --- daemon/parted.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/daemon/parted.c b/daemon/parted.c index 124d1e9..03e83cb 100644 --- a/daemon/parted.c +++ b/daemon/parted.c @@ -320,6 +320,8 @@ print_partition_table (const char *device, bool add_m_option) CLEANUP_FREE char *err = NULL; int r; + udev_settle (); + if (add_m_option) r = command (&out, &err, str_parted, "-m", "-s", "--", device, "unit", "b", @@ -328,6 +330,9 @@ print_partition_table (const char *device, bool add_m_option) r = command (&out, &err, str_parted, "-s", "--", device, "unit", "b", "print", NULL); + + udev_settle (); + if (r == -1) { int errcode = 0; @@ -665,6 +670,8 @@ sgdisk_info_extract_field (const char *device, int partnum, const char *field, return NULL; } + udev_settle (); + CLEANUP_FREE char *err = NULL; int r = commandf (NULL, &err, COMMAND_FLAG_FOLD_STDOUT_ON_STDERR, str_sgdisk, device, "-i", partnum_str, NULL); @@ -674,6 +681,8 @@ sgdisk_info_extract_field (const char *device, int partnum, const char *field, return NULL; } + udev_settle (); + CLEANUP_FREE_STRING_LIST char **lines = split_lines (err); if (lines == NULL) { reply_with_error ("'%s %s -i %i' returned no output",
