Operating Systems AIX 2.6TB filesystem to be copied or moved to another FS ? Post 302483285 by filosophizer on Saturday 25th of December 2010 08:00:36 AM

mirrorlv for the above example : filesystem of 200G allocation with actual Data of 100.6 GB takes around 3.5 hours.

Note: the filesystem / logical / volume group is from SAN Storage connected by one 4 GB fiber.

so we are here copying a filesystem/logical volume from SAN Storage to SAN Storage.

So, if 200G logical volume takes 3.5 hours with mirrorlv imagine 2.6TB ?
around 40 hours or so ?

next I will try to cp as zxmaus or as bakunin said, will backup and restore.

NAME
lvremove - remove a logical volume SYNOPSIS
lvremove [-A|--autobackup {y|n}] [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--version] [-f|--force] [--noudevsync] LogicalVol- ume{Name|Path} [LogicalVolume{Name|Path}...] DESCRIPTION
lvremove removes one or more logical volumes. Confirmation will be requested before deactivating any active logical volume prior to removal. Logical volumes cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem). Removing an origin logical volume will also remove all dependent snapshots. If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com- mand issued from one node can do this. OPTIONS
See lvm(8) for common options. -f, --force Remove active logical volumes without confirmation. --noudevsync Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre- ates. EXAMPLES
Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation: lvremove -f vg00/lvol1 Remove all logical volumes in volume group vg00: lvremove vg00 SEE ALSO
