LVM Inkonsistent

[felus]

Hallo,
Ich hab ein raid5 worauf lvm2 läuft. Das LVM beseht aus einer Volumegruppe und erstmal nur 1 logisches volumen.Konkret sieht das so aus:
Raid->LVM2->DM-Crypt->XFS


nun wurde leider nicht mein computer ordnungsgemäß heruntergefahren und das lvm will einfach nicht mehr starten.

das einzige was ich gefunden hab ist 'vgcfgrestore' aber dazu hätte ich wohl erst ein backup machen müssen.

Edit:
ich habe eine backupdatei gefunden, die von gestern ist. Leider klappt es mit ihr nicht


server ~ # vgcfgrestore -v -f /etc/lvm/backup/vg vg

Würde mich sehr über eine Lösung freuen.

[bla!zilla]

Poste mal die /etc/lvm/lvm.conf.

devices {

dir = "/dev"
scan = [ "/dev" ]
preferred_names = [ ]
filter = [ "r|/dev/nbd.*|", "a/.*/" ]
cache_dir = "/etc/lvm/cache"
cache_file_prefix = ""
write_cache_state = 1
sysfs_scan = 1
md_component_detection = 1
ignore_suspended_devices = 0
}

log {
verbose = 0
syslog = 1
overwrite = 0
level = 0
indent = 1
command_names = 0
prefix = " "
}

backup {
backup = 1
backup_dir = "/etc/lvm/backup"
archive = 1
archive_dir = "/etc/lvm/archive"
retain_min = 10
retain_days = 30
}

shell {

history_size = 100
}


global {

umask = 077
#umask = 022
test = 0
units = "h"
activation = 1
fallback_to_lvm1 = 0
format = "lvm2"
proc = "/proc"
locking_type = 1
fallback_to_clustered_locking = 1
fallback_to_local_locking = 1
locking_dir = "/var/lock/lvm"
}

activation {
missing_stripe_filler = "/dev/ioerror"
reserved_stack = 256
reserved_memory = 8192
process_priority = -18
mirror_region_size = 512
readahead = "auto"
mirror_log_fault_policy = "allocate"
mirror_device_fault_policy = "remove"
}


metadata {
pvmetadatacopies = 2
}

# Gentoo: uncommented, since we provide the dmeventd init script
dmeventd {
mirror_library = "libdevmapper-event-lvm2mirror.so"
snapshot_library = "libdevmapper-event-lvm2snapshot.so"
}


in /etc/lvm/archive sind auch Dateien von vg_00000.g bis vg_00023.vg
wobei da das gleiche drin steht wie in der /etc/lvm/backup/vg und kein vgcfgrestore funktioniert
