Unable to create a Logical Volume

[marvik]

Dear All,
I am unable to create a LVOL on Linux.

vgdisplay -v vg00 shows::

Loaded external locking library liblvm2clusterlock.so
Using volume group(s) on command line
Finding volume group "vg00"
--- Volume group ---
VG Name vg00
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 13
VG Access read/write
VG Status resizable
MAX LV 0

lvcreate -L 3G -n lvcrash vg00
Error locking on node g1pdwap13: Volume group for uuid not found: zbMvwQsDfdtewXed5nuHCTzLnS0eTy1p58qjMbHgJMzCf6RSuWICbpitXX3LqyEp
Failed to activate new LV.

LVOL is created but is unavailab


Red Hat Enterprise Linux ES release 4 (Nahant Update 5)le.
I tried doing

root@pdwap13:~# lvchange -ay /dev/vg00/lvcrash
Error locking on node g1pdwap13: Volume group for uuid not found: zbMvwQsDfdtewXed5nuHCTzLnS0eTy1p58qjMbHgJMzCf6RSuWICbpitXX3LqyEp

Any suggestion are highly appreciated.

Thanks

Hello MArvik,

Boot into Rescue Mode.

# vgchange -a n vg00
# vgchange -u vg00
# vgchange -a y vg00
# vgdisplay -v vg00
# mount -a
# df

Thanks

You are using cluster locking, then you need to start the clvmd service, or disable cluster locking if this host is not part of a cluster.

lvcreate -n logical_volume_one --size 255G volume_group_one
Instead of specifying the LV size in GB we could also specify it in terms of logical extents. First we use vgdisplay to determine the number of PEs in the volume_group_one:


vgdisplay volume_group_one | grep "Total PE"

which returns


Total PE 65536

Then the following lvcreate command will create a logical volume with 65536 logical extents and fill the volume group completely:
