Intel Modular Server System MFSYS25 Installation Experiences

[Petrus4]

ok I finally got the system to boot by changing /etc/fstab to:

# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext3 errors=remount-ro 0 1
/dev/pve/data /var/lib/vz ext3 defaults 0 1
#UUID=29133336-a2aa-4d47-9ccd-a4b380dff280 /boot ext3 defaults 0 1
/dev/dm-3 /boot ext3 defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0
#UUID=777b58c2-c780-41c3-919f-3640e4f5cce6 /srv ext3 defaults 0 2
/dev/dm-6 /srv ext3 defaults 0 2

But Multipath is still not working correctly:

proxmox-IN-M:~# multipath -llsdf: checker msg is "directio checker reports path is down"

Does anyone have an idea of why this may not be working?

Hi,
it's a little bit less info for that...
Perhaps a filter in /etc/lvm/lvm.conf?
What is the output of "blkid"?

Hi,
multipath can't work, because you see the disks only via one path.
The host see only three disks instead of six.
Something wrong with the assigning? (sorry don't know the intel modular server).
