Problem migrating disk attached to the same vg (lvm)
Hi,
I'm trying to migrate the content of disk 'A' to disk 'B', that they belong to the same vg 'data'_vg'. Whe using pvmove, I get the following error: 'device-mapper: suspend ioctl failed: Interrupted system call'. I put down the whole trace:
Hiya,
Is there a known method from converting LVM data to VxVM data..
ie we have a load of local and SAN (HPDM) mounts on RHEL 4u5/5u1 servers which are now required to be clustered with SFS (VxFS,VxVM,CFS,VCS etc)
I've come across the vxvmconvert, but thought that was HP-UX only?

Hi guys,
I would like to ask your opinion about my theory, how to fix my broken LVM without risking any data loss.
I use Archlinux at home. I just love this distro, even it gives me a lots of work (particularly after system updates).
Basic system spec:

Scenario1:
VG00 lvm,not mirrored,2 disk of 36GB vg size
VG00 size is under 30G.
Is possible to remove a disk of 36GB and replace "on fly"
with a disk of 300GB on VG00?
Thanks (6 Replies)
My project: i want to migrate from a vg00(actual 75GB disk) to a new vg01 (300GB disk),hpux is 11.31 on itanium efi system.
vg00 is disk0
vg01 is disk8
I did this
#check disk dimension
diskinfo -b /dev/rdisk/disk0_p2 | awk '{print $1/1024}'
#create a part file

vgcfgrestore
VGCFGRESTORE(8) System Manager's Manual VGCFGRESTORE(8)NAME
vgcfgrestore - restore volume group descriptor area
SYNOPSIS
vgcfgrestore [-b|--backup_number VolumeGroupBackupNumber] [-d|--debug] [-f|--file VGConfPath] [-l[l]|--list [--list]] [-h|--help]
[-i|--ignore_size] [-n|--name VolumeGroupName] [-o|--oldpath OldPhysicalVolumePath] [-t|--test] [-v|--verbose] [PhysicalVolumePath]
DESCRIPTION
vgcfgrestore allows you to restore the volume group descriptor area from backup files in /etc/lvmconf or from VGConfPath to the given Phys-
icalVolumePath. The default backup file is /etc/lvmconf/VolumeGroupName.conf. This command DOES NOT restore data contained in logical
volume(s), only the LVM configuration metadata!
OPTIONS
-b, --backup_numberVolumeGroupBackupNumber
Restore from the specified backup number. Use together with option -n which gives the name of the volume group. See examples below.
-d, --debug
Enables additional debugging output (if compiled with DEBUG).
-f, --file VGConfPath
Restore from the specified path. Useful for selection of specific backups in the backup history or for copies of VGDA backups.
-i, --ignore_size
Restore though the size of the physical volume doesn't match the one in the backup.
-l, --list
Display volume group information contained in the backup file. If given twice, the physical and logical volume information con-
tained in the backup file is also shown.
-h, --help
Print a usage message on standard output and exit successfully.
-n, --name VolumeGroupName
Do a restore for this volume group name.
-o, --oldpath OldPhysicalVolumePath
If the path to the physical volume has changed between backup time and restore time, this option enables you to choose the corre-
sponding physical volume path in the backup file.
-t, --test
Do a test run reading the volume group backup WITHOUT trying to restore it
-v, --verbose
Give verbose runtime information about vgcfgrestore's activities.
--version
Output the version number and exit successfully.
Examples
To display information like with "vgdisplay vg00" stored in the backup file /etc/lvmconf/vg00.conf:
vgcfgrestore -n vg00 -l
To restore the VGDA of vg00 from the alternative backup file /tmp/vg00-old to physical volume /dev/sdn1:
vgcfgrestore -f /tmp/vg00-old -n vg00 /dev/sdn1
To restore the VGDA of vg00 from the alternative backup file
/etc/lvmconf/vg00.conf.5.old
to physical volume
/dev/sda5 :
vgcfgrestore -n vg00 -b 5 /dev/sda5
DIAGNOSTICS
vgcfgrestore returns an exit code of 0 for success and > 0 for error:
1 no physical volume on command line
2 invalid physical volume name
3 volume group is active
4 error doing restore to physical volume
5 backup is invalid for this volume group
6 volume group is inconsistent
7 physical volume doesn't belong to volume group backup
8 error reading physical volume
9 error getting size of physical volume
10 error writing VGDA to physical volume(s)
11 error removing special files of volume group
12 error setting volume group into lvmtab
13 error doing backup
95 driver/module not in kernel
96 invalid I/O protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line
