Package: multipath-tools
Version: 0.8.5-2
Severity: important
X-Debbugs-Cc: [email protected]
Dear Maintainer,
A server was setup with some disks configured in multipath.
The root filesystem is on LVM on internal disk, not configured for multipath.
Then build another lvm configuration on those devices (/dev/mapper/...)
Now, every time it starts, lvm takes the /dev/sd.. before multipath sets
/dev/mapper/... up.
Also, the booting proccess delays for 2+ minutes, mostly because of
systemd-udev-settle.service:
root@panblando:~# systemd-analyze blame
2min 22ms systemd-udev-settle.service
1min 105ms NetworkManager-wait-online.service
9.983s smartmontools.service
4.415s dev-mapper-dl380g8\x2d\x2dvg\x2droot.device
But this service is called from multipath:
[Unit]
Description=Device-Mapper Multipath Device Controller
Wants=systemd-udev-trigger.service systemd-udev-settle.service
Before=iscsi.service iscsid.service lvm2-activation-early.service
Before=local-fs-pre.target blk-availability.service
After=multipathd.socket systemd-udev-trigger.service
systemd-udev-settle.service
DefaultDependencies=no
Conflicts=shutdown.target
ConditionKernelCommandLine=!nompath
ConditionKernelCommandLine=!multipath=off
According to systemd-udev-settle.service(8) it is not recommended, as that
service can fail (in fact,
in the server it fails as systemd says)
I think that the problem is related to multipath, because it did not setup the
devices before lvm,
and maybe the problem is inside the initrd.
Then I did install multipath-tools-boot but the problem is the same.
The only way is to avoid mounting the filesystems in the LVM (or umounting
them) vgchange -an VG
and do the multipath and mount it, all by hand
The disk list in multipath is short (8 disks with only 1 path each by now)
Best regards,
Carlos Barros.
