Operating Systems Linux Red Hat Moving filesystems into LVM - query. Post 302925921 by Peasant on Thursday 20th of November 2014 07:58:43 AM

I have recently moved a 2 TB database on HPUX with pvmove from one storage to another.

This was being done lun per lun.

It was done during the day (night is peak in this enviroment), everything went fine with no issues whatsoever.

This is probably due to everything being done on 8G FC network and high end storage with alot of cache.

NAME
pvck - check physical volume metadata SYNOPSIS
pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...] DESCRIPTION
pvck checks physical volume LVM metadata for consistency. OPTIONS
See lvm for common options. --labelsector sector By default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0. This parameter allows you to specify a different starting sector for the scan and is useful for recovery situations. For example, suppose the partition table is corrupted or lost on /dev/sda, but you suspect there was an LVM partition at approximately 100 MB. This area of the disk may be scanned by using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800): pvck --labelsector 204800 /dev/sda Note that a script can be used with --labelsector to automate the process of finding LVM labels.
