[SOLVED] LVM auf durchgereichten Festplatten -> Fehler am Host

[der-brumm-baer]

Hallo,

Ich betreibe auf meinem Proxmox Server einen Openmediavault Filserver.
Hierfür habe ich einen SATA Controller an das virtuelle KVM-System durchgereicht.
Die daran angeschlossenen Festplatten sind auch mittels LVM partitioniert.

Jetzt habe ich das Problem, dass die Volumes auf diesen Platten auch im vgscan des Host
auftauchen, aber eben als fehlende Partitionen
Ausgabe von vgscan:

  Reading all physical volumes.  This may take a while...

  Found volume group "pve" using metadata type lvm2

Jetzt habe ich schon versucht, in der /etc/lvm/lvm.conf einen Filter zu setzen, doch das
scheint nicht zu wirken:

      # Example
        # Accept every block device:
        # filter = [ "a|.*/|" ]
        # Reject the cdrom drive:
        # filter = [ "r|/dev/cdrom|" ]
        # Work with just loopback devices, e.g. for testing:
        # filter = [ "a|loop|", "r|.*|" ]
        # Accept all loop devices and ide drives except hdc:
        # filter = [ "a|loop|", "r|/dev/hdc|", "a|/dev/ide|", "r|.*|" ]
        # Use anchors to be very specific:
        # filter = [ "a|^/dev/hda8$|", "r|.*/|" ]
        #
        # This configuration option has an automatic default value.
        # filter = [ "a|.*/|" ]
        filter = [ "r|/dev/sdb|", "r|/dev/sdc|" ]

Mit dmesg und im syslog taucht auch laufend folgende Fehlermeldung auf:

dmesg:

[58646.459708] blk_partition_remap: fail for partition 1

syslog:

pve kernel: [58656.623222] blk_partition_remap: fail for partition 1

Wie kann ich die Festplatten vom Scan in LVM ausschliessen?

MfG
Sven

Hallo,

habe es jetzt hinbekommen.

Zusätzlich habe ich noch den "global_filter" um die Anfangsbuchstaben des Namens der VolumeGroup
erweitert. ( , "r|/dev/mapper/vg.*|")

        # Do not scan ZFS zvols (to avoid problems on ZFS zvols snapshots)
        global_filter = [ "r|/dev/zd.*|", "r|/dev/mapper/pve-.*|" , "r|/dev/mapper/vg.*|"]

        # Example
        # Accept every block device:
        # filter = [ "a|.*/|" ]
        # Reject the cdrom drive:
        # filter = [ "r|/dev/cdrom|" ]
        # Work with just loopback devices, e.g. for testing:
        # filter = [ "a|loop|", "r|.*|" ]
        # Accept all loop devices and ide drives except hdc:
        # filter = [ "a|loop|", "r|/dev/hdc|", "a|/dev/ide|", "r|.*|" ]
        # Use anchors to be very specific:
        # filter = [ "a|^/dev/hda8$|", "r|.*/|" ]
        #
        # This configuration option has an automatic default value.
        # filter = [ "a|.*/|" ]
        filter = [ "r|/dev/sdb|", "r|/dev/sdc|" ]

der lvscan ist jetzt sauber, und die Fehler im dmesg und syslog sind auch verschwunden.
