[Libguestfs] [PATCH] daemon: consider /etc/mdadm/mdadm.conf while inspecting mountpoints.

From: Nikolay Ivanets <stenavin(a)gmail.com&gt; Inspection code checks /etc/mdadm.conf to map MD device paths listed in mdadm.conf to MD device paths in the guestfs appliance. However on some operating systems (e.g. Ubuntu) mdadm.conf has alternative location: /etc/mdadm/mdadm.conf. This patch consider an alternative location of mdadm.conf as well. --- daemon/inspect_fs_unix_fstab.ml | 13 ++++++++----- daemon/inspect_fs_unix_fstab.mli | 3 ++- 2 files changed, 10 insertions(+), 6 deletions(-) diff --git a/daemon/inspect_fs_unix_fstab.ml b/daemon/inspect_fs_unix_fstab.ml index 170440d2c..9d54dadda 100644 --- a/daemon/inspect_fs_unix_fstab.ml +++ b/daemon/inspect_fs_unix_fstab.ml @@ -38,14 +38,15 @@ let re_xdev = PCRE.compile "^/dev/(h|s|v|xv)d([a-z]+)(\\d*)$" let rec check_fstab ?(mdadm_conf = false) (root_mountable : Mountable.t) os_type = - let configfiles = - "/etc/fstab" :: if mdadm_conf then ["/etc/mdadm.conf"] else [] in + let mdadmfiles = + if mdadm_conf then ["/etc/mdadm.conf"; "/etc/mdadm/mdadm.conf"] else [] in + let configfiles = "/etc/fstab" :: mdadmfiles in with_augeas ~name:"check_fstab_aug" configfiles (check_fstab_aug mdadm_conf root_mountable os_type) and check_fstab_aug mdadm_conf root_mountable os_type aug = - (* Generate a map of MD device paths listed in /etc/mdadm.conf + (* Generate a map of MD device paths listed in mdadm.conf * to MD device paths in the guestfs appliance. *) let md_map = if mdadm_conf then map_md_devices aug else StringMap.empty in @@ -224,11 +225,13 @@ and map_md_devices aug = if StringMap.is_empty uuid_map then StringMap.empty else ( (* Get all arrays listed in mdadm.conf. *) - let entries = aug_matches_noerrors aug "/files/etc/mdadm.conf/array" in + let entries1 = aug_matches_noerrors aug "/files/etc/mdadm.conf/array" in + let entries2 = aug_matches_noerrors aug "/files/etc/mdadm/mdadm.conf/array" in + let entries = List.append entries1 entries2 in (* Log a debug entry if we've got md devices but nothing in mdadm.conf. *) if verbose () && entries = [] then - eprintf "warning: appliance has MD devices, but augeas returned no array matches in /etc/mdadm.conf\n%!"; + eprintf "warning: appliance has MD devices, but augeas returned no array matches in mdadm.conf\n%!"; List.fold_left ( fun md_map entry -> diff --git a/daemon/inspect_fs_unix_fstab.mli b/daemon/inspect_fs_unix_fstab.mli index 4778fd962..2ca06debc 100644 --- a/daemon/inspect_fs_unix_fstab.mli +++ b/daemon/inspect_fs_unix_fstab.mli @@ -24,7 +24,8 @@ val check_fstab : ?mdadm_conf:bool -> Mountable.t -> Inspect_types.os_type -> this function also knows how to map (eg) BSD device names into Linux/libguestfs device names. - [mdadm_conf] is true if you want to check [/etc/mdadm.conf] as well. + [mdadm_conf] is true if you want to check [/etc/mdadm.conf] or + [/etc/mdadm/mdadm.conf] as well.
